South Africa throws away 2 million doses of COVID-19 vaccine due to contamination incident. Photo: Reuters According to RT (Russia) news agency (Russia), the South African Health Products Administration (SAHPRA) has decided not to deploy vaccination for 2 million doses of Johnson & Johnson vaccine being stored at a facility in the city of Gqeberha. , as the raw materials for their production were affected by a contamination incident at the factory in Baltimore (USA). The decision comes after the US Food and Drug Administration (FDA) said that millions of doses of vaccine produced at Johnson & Johnson’s Emergent BioSolutions facility in the US city of Baltimore were not suitable for use in the United States. use. “Based on what has been announced by the FDA, batches of vaccines being stored in our Gqeberha have been affected. The batches of these vaccines correspond to about 2 million doses,” South Africa’s Acting Health Minister Mmamoloko Kubayi-Ngubane said on June 13. These doses of the vaccine have not and will not be used to immunize South Africans, she added. SAHPRA chief executive, Dr Boitumelo Semete, also confirmed the batch of vaccines “cannot be widely distributed.” Meanwhile, South Africa’s health watchdog said in a statement that a new batch of about 300,000 doses of Johnson & Johnson’s COVID-19 vaccine has been approved by the FDA and will be shipped to South Africa at a later date. some point. The agency did not disclose the exact date the shipments arrived. However, Mr. Semete acknowledged that the problem with Johnson & Johnson’s vaccine had a significant negative impact on South Africa’s vaccine deployment strategy. As of June 13, South Africa, the country hardest hit by the COVID-19 epidemic in Africa, has recorded about 1.7 million cases of COVID-19 and over 57,000 deaths. However, the country with a population of about 58.5 million people has only injected 183,000 doses of the vaccine to its people, as of June 9, according to the World Health Organization (WHO). South Africa is also one of the countries that is campaigning to give up patents for a COVID-19 vaccine to allow all countries to produce generic versions at low cost. “If we want to save lives and end the pandemic, we need to expand and diversify our production, put medical products into treatment, and fight and stop the pandemic for as many people as possible,” the president said. South Africa Cyril Ramaphosa speaks at a meeting with G7 countries in the UK on June 13.

According to the Beautynesia The most common mistake when using sunscreen is chống unevenly applied .

You should note that the skin needs time to absorb sunscreen products, against the harmful effects of UVA and UVB rays. Image: Flipboard . If exposed to the sun immediately after using the cream, the product has not fully exerted its effects on the skin. Therefore, you should wait about 30 minutes after using the product and then go out. Photo: Stocksy United. The third mistake was written by Beautynesia mentioned is Use sunscreen only when you want to go out . It is obvious that the skin is exposed to direct sunlight when we are outdoors. But the skin can still be exposed to sunlight through windows and glass. Therefore, you should use sunscreen even when indoors. Image: Yahoo! .

Students in South Korea have returned to normal school with splash shields. (Photo: AP) However, the FDA also emphasized that each country’s approach may vary, so it does not recommend any approach to the United States to deal with new infectious diseases that will emerge. The above report introduces Korea’s approach to the COVID-19 epidemic, based on lessons learned from the Middle East Acute Respiratory Syndrome (MERS) outbreak in 2015, detailing the Korea’s efforts to deal with infectious diseases. The report indicates that the Seoul Government has invested heavily in the commercial use of infectious disease diagnostic technology, which has helped Korean private enterprises develop and rapidly produce testing equipment. In addition, South Korea followed the US, applying an “emergency use authorization” (EUA) regime for COVID-19 diagnosis. The Korean justice agency has revised the law, so that the authorities have the right to collect information about patients and people suspected of having infectious diseases in critical situations. Along with that, measures such as mandatory wearing of masks, social distancing, stopping some business activities, and effective exchange strategies, have helped South Korea contain the wave of COVID-19 spread. On the other hand, according to the ranking of resilience from the COVID-19 epidemic (Covid Resilience Ranking) published by Bloomberg (USA) every month, South Korea ranked 5th out of 53 assessed countries, an increase of one place compared to the previous year. with April. Korea’s highest ranking was 4th in November last year.

“Logically, minimizing exposure will help reduce harm.” To date, health authorities have argued that the FDA’s decision only allows the product to be designated “reduced exposure”, but that does not prove that heated tobacco products reduce the risk of disease to the health of the user. use. In addition, there have also been some medical experts who have made statements that contradict the FDA’s decision, saying that the product is not different from cigarettes. According to official information from the FDA, studies on heated tobacco have demonstrated that the aerosols produced by these products still contain high levels of harmful and potentially harmful ingredients, including: formaldehyde, acrolein, carbon monoxide; NNN and NNK (substances related to diseases caused by tobacco smoke) but significantly lower than the currently circulating combustible cigarettes. Specifically, depending on the type of substance, the average concentration in aerosol gas will be reduced from 55% to 99% compared to the smoke of cigarettes. The FDA declares a heated tobacco product to be marketed in the United States as a risk-modified tobacco product. At the same time, the FDA also said that in the process of reviewing the records, FDA has consulted users. The results showed that users also found that the risk of using these products was lower than that of smoking cigarettes. However, they are also fully aware that using this heated tobacco product carries a higher risk than quitting smoking or using nicotine replacement products. PGS.TS.BS. Tran Van Ngoc – Chairman of the Ho Chi Minh City Respiratory Association said that, logically, minimizing exposure will help reduce harm. Assoc. Dr. Le Van Quang, Director of Central K Hospital also stated: “From the oncologist’s perspective, when a patient smokes, the greater the amount of carcinogens exposed, the higher the cancer risk. And for cigarettes, one thing is important: nicotine is not the cause of cancer caused by smoking, but the cause of cancer is the molecules in the smoke created by the combustion of cigarettes. leaves”. Heated cigarettes: Young people are many times harder to access than cigarettes The US FDA is a reputable health authority in the US as well as globally. Accordingly, protecting the young generation and people’s health is the top goal of FDA. Therefore, allowing a single heated tobacco product to be allowed access to the US market shows that they have done thorough research and considered carefully before making a decision. Not only in the US, but in countries where this product is allowed to be sold, it is almost impossible for young people to access the product. In order to make a purchase, the buyer must go through a background check to ensure that the buyer is a smoker and is of legal age of majority in the country of origin. At the same time, although allowing this tobacco product to be commercialized, FDA also requires manufacturers to regularly update their sales and trade processes to ensure control of young people’s access to the product. This product is at its lowest. Meanwhile, compared to heated cigarettes, young people can easily buy cigarettes anywhere with as cheap as giving. FDA representative, Dr. Priscilla Callahan-Lyon, confirmed that the FDA has carefully studied the issue of the product’s impact on young people. Accordingly, in terms of appearance, a heated cigarette is a rather large set of equipment, difficult to conceal and is not cheap, must be used with its own custom cigarette, and this product also does not contain attractive aromas. young. Not only in the US, but in countries that allow the circulation of heated cigarettes, the level of impact of this product on young people or new users is almost under control. Despite accounting for 85% of global sales of heated cigarettes, only 0.1% of middle and high school students in Japan use heated cigarettes daily, which is only one-fifth of the total. percentage of students smoking burned cigarettes. It is worth noting that the number of students using heated cigarettes is the same group of students who have used cigarettes before. According to an independent study of 7,000 teenagers in Germany, the number of people aged 12-17 who used a heated tobacco product in the 30 days before the survey was almost zero. One study Another independent study of more than 11,000 teenagers aged 11-15 years old in Switzerland also found that less than 2% had ever used heated tobacco, while the number of people who smoked lit cigarettes in this same age range increased. to over 33%. Regulating heated tobacco: No violation of the FCTC . Framework Convention In a seminar held recently, Ms. Tran Thi Trang, Deputy Director of the Legal Department, Ministry of Health said: “The Ministry of Health proposes not to allow the import and sale of e-cigarette products, heated cigarettes because these products are addictive, harmful to health, and cannot be piloted for people’s health.” If according to the above argument, invisibly, cigarettes – the product with the highest level of addiction and harm to the health of users and the community – becomes a product that is protected exclusively and consumers. no longer have the right to choose harm reduction products. “Smokers don’t deserve to die just because they don’t know about less harmful nicotine products,” said Cliff Douglas, director of the University of Michigan’s Tobacco Research Network and former director of the Centers for Disease Control and Prevention. American Cancer Society (ACS) Tobacco Control Policy, former Advisory Counsel on Tobacco Control Policy to the US Surgeon General. Meanwhile, the Framework Convention on Tobacco Control (FCTC) of the World Health Organization (WHO) also recognizes heated tobacco as a tobacco product. Therefore, if Vietnam manages heated tobacco like the current tobacco control law in the host country, it is also completely consistent with what the Framework Convention has stipulated. Lawyer Phan Hoang Lam, Law Firm DT LAW. On the other hand, Lawyer (LS) Phan Hoang Lam, DT LAW Law Firm said that: The Law on Prevention and Control of Tobacco Harms 2012 defines “tobacco is a product produced from all or part of tobacco ingredients, processed in the form of cigarettes, cigars, tobacco, pipe tobacco or other forms”. On this basis, heated tobacco is considered “tobacco” because it contains tobacco leaf ingredients, consistent with the concept of “tobacco” under the current legal provisions of Vietnam. Therefore, this drug should absolutely be regulated by Vietnam’s Drug Prevention and Control Law. According to LS Lam, in order to manage smokeless tobacco products more effectively, Vietnam needs to consider international scientific bases to evaluate and compare the level of harm to health of tobacco. smokeless compared to burned cigarettes. At the same time, with the function of State management, in order to create free and fair competition among manufacturers and products and protect the interests of consumers, protect public health, regulatory agencies The state should immediately come up with a plan to build a legal corridor for the production, circulation and control of these products.

Accordingly, heated tobacco products are designated as tobacco products that reduce exposure to harmful substances to the body compared to cigarettes. This decision of the FDA is also a response to some concerns of governments around the world about the ability of products to reduce harm. In addition, other concerns were also answered by experts. The risk is lower than with cigarettes, higher than that of quitting To date, health authorities are concerned that the FDA’s decision to only allow products to be designated “reduced exposure” does not prove that heated tobacco products reduce the risk of disease to human health. use.

Need a plan to build a legal corridor According to the Framework Convention on Tobacco Control (FCTC) of the World Health Organization (WHO), which Vietnam has acceded to and entered into force in March 2005, in the definition under article 1, item (f) published on the website of the Foundation for Prevention of Tobacco Harms (Vinacosh) also clearly states: “tobacco products” means products which are wholly or partly derived from tobacco materials manufactured to for sucking, sucking, chewing or inhaling. The 8th Conference of the Parties (COP8) held by WHO at the end of 2018 also once again reiterated that heated tobacco is recognized as a tobacco product. From this definition and the COP8 guidelines, it can be seen that whether according to the definition of the 2012 Law on Drugs and Prevention of Vietnam, or within the definition of the WHO Framework Convention on FCTC 2005, heated tobacco is a products must be subject to the control of the current Law on Drug Prevention and Control. Lawyer Phan Hoang Lam, Law Firm DT LAW On the other hand, lawyer Phan Hoang Lam, DT LAW Law Firm, said that the Law on Prevention of Tobacco Harms 2012 defines “Tobacco is a product manufactured from all or part of medicinal ingredients. leaves, processed in the form of cigarettes, cigars, tobacco, pipe tobacco or other forms”.

Many world-famous models, actors and athletes have applied EMS technology to practice to get a balanced body, healthy fitness or support recovery from injury. Currently, Europe alone has more than 6,000 gyms using this technology. Many benefits in just one machine The EMS training principle is based on the transmission of low-frequency electrical impulses to the muscle bundles through electrodes attached training suits. The impulses stimulate the muscles to contract on a natural reflex, similar to when exercising at high intensity. Compared to traditional training, EMS technology helps the practitioner impact muscle groups more comprehensively, from the outer to deep inside, stimulated by electrical impulses. From the special mechanism above, even without performing separate exercises with different tools for each muscle group, the practitioner still achieves high efficiency in fat loss and muscle building. Therefore, the time saved between a training session with EMS technology compared to a traditional gym is not small. A training session with EMS technology takes less than 25 minutes and only needs to maintain 2 sessions / week. As a result, this method is favored by people who are busy or unable to exercise vigorously such as office workers, business people, housewives, middle-aged people … Thanks to EMS technology, trainees only spend 25 minutes / training session, 2 sessions / week. According to research by Bayreuth University in Germany, after 6 weeks of applying EMS technology, 85% of trainees noticed a marked change in physique, slimmer body and firmer muscles. The study results also showed that training with full body EMS technology created 40% higher training intensity than traditional training with weights. Specifically, overall strength increased by 12%, while endurance and fitness improved by 69%. In addition, EMS technology is also considered to be a safe method of training because it does not need vigorous exercise or performing difficult exercises, so it can significantly eliminate the risk of injury. Practitioners just need to wear specialized outfits and perform some exercises with simple and easy to remember postures and movements. In addition, the electrical current of the EMS exercise machine is low frequency, so it does not create pain or cause the practitioner to lose a lot of energy. Along with reducing fat and gaining muscle, the electrical impulses from the EMS exercise machine also help the body boost metabolism. From there, the practitioner can improve blood circulation, eliminate accumulated toxins, strengthen the immune system and maintain a more relaxed, energetic spirit. This is also an ideal therapeutic support method for office workers, helping to reduce symptoms of neck and neck pain, back pain, and hernias by positively impacting the skeletal system and blood vessels. Besides improving physique, EMS technology also helps to reduce back pain, shoulder and nape. Become a favorite exercise model In recent years in Vietnam, EMS technology has been more applied to sports practice and has begun to receive great attention. In particular, 25 Fit is one of the pioneering centers to invest in applying this technology on a large scale with a methodical and professional operation according to the standards of modern EMS gyms in Europe. All gyms at 25 Fit are equipped with EMS exercise machines from Miha Bodytec firm. This is one of the first EMS Training equipment suppliers in the world to be certified by FDA (USA) for safety and quality standards. The machine consists of a control panel, a training shirt that integrates electrodes and an adapter cable that conducts electrical impulses, all designed to deliver high training efficiency and ensure user safety. In addition, each customer will get 25 Fit equipped with a functional clothes inside to maintain the moisture on the skin and help the electrical impulses be transmitted optimally. This garment is manufactured by Miha Bodytec from a fabric with modern technology and high antibacterial ability. 25 Fit’s EMS exercise machine meets FDA (USA) quality and safety standards. Besides EMS machine, before every training session at 25 Fit, customers will be trained by trainers to use pre-workout to replenish energy and increase endurance. At the same time, the trainer will carefully check the daily fitness index with the InBody machine to adjust the exercise and give advice to the customer to adjust the exercise regimen and nutrition accordingly. Coming to 25 Fit, trainees can also enjoy the luxurious and airy gym space; Use bathroom, private dressing room, fully equipped with modern equipment and amenities.

COVID-19 vaccine from Johnson & Johnson. Photo: AFP / VNA On April 13, US federal health authorities recommended to suspend the use of Johnson & Johnson’s COVID-19 vaccine for “cautious” reasons, awaiting the results of investigating the possible link between the vaccination. this with thrombotic side effect. The Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) are reviewing six cases of thrombosis following the vaccination. Meanwhile, according to Reuters, on April 15, US infectious disease expert Anthony Fauci hopes that US regulators will soon make a quick decision on resuming Johnson & Johnson’s vaccination, bringing the vaccine back. immunization program. The day before, the US CDC advisory committee postponed at least a week to vote on whether to resume use of the Johnson & Johnson vaccine to wait for more data on thrombotic risks. Mr. Fauci feared that the prolonged delay of the vaccine could affect people’s hesitancy. “I think we need to continue to emphasize that this is a very effective and usable vaccine that is very, very valuable in a global context,” he said. Following the US, some countries have made similar moves with the Johnson & Johnson vaccine
On April 13, the South African Ministry of Health announced it had suspended the use of the Johnson & Johnson vaccine in the country’s vaccination program, although South Africa has not received a report related to coagulation after 290,000 people in the country. has received the COVID-19 vaccine from the brands. Two weeks ago, South Africa licensed the use of vacicne Johnson & Johnson and so far only vaccinated this vaccine to health workers in the study framework. Before the above developments, Dutch Health Minister Hugo de Jonge said that the country has not decided whether to launch the Johnson & Johnson vaccine injection this week or not. He stated that the Netherlands will wait for information from the European Pharmaceutical Authority (EMA) before making a decision. In contrast, some countries continue to use the Johnson & Johnson vaccine. Belgium has said it will not stop the vaccination at this stage. Poland started to vaccinate Johnson & Johnson when the government confirmed that the benefits of the vaccine outweigh the risks. Meanwhile, Spanish officials have not received the notice of stopping the Johnson & Johnson vaccination. For its part, the World Health Organization (WHO) says it is monitoring global data of various reports to see if similar cases occur elsewhere, and it will take time. Time to evaluate vaccine data from Johnson & Johnson. Denmark completely discontinues the AstraZaneca vaccine; Thailand is still considered the mainstay Prime Minister of Thailand Prayut Chan-O-Cha (middle) was vaccinated against COVID-19 by AstraZeneca company in Bangkok, on March 16, 2021. Photo: AFP / VNA Before the Johnson & Johnson vaccine, the AstraZeneca vaccine was also in the same situation. The AstraZeneca vaccine is suspected of causing thrombosis, causing a series of European countries to suspend use, despite WHO recommendations. Recently, on April 14, Denmark became the first European country to permanently stop using the AstraZeneca vaccine due to concerns about rare blood clotting side effects. Denmark thinks that AstraZeneca’s vaccine may not be needed because it has managed the COVID-19 pandemic and may just depend on the vaccines from Pfizer and Moderna. Before that, from March 11, Denmark, along with Iceland and Norway, have suspended the use of this vaccine. Followed by a number of other European countries, including France, Germany and Italy. Federal Health Ministers and states in Germany unanimously recommend a second shot after getting the first shot with the AstraZeneca vaccine, under which one shot of the preparation is given to those under 60 years of age. This could be a second shot with another vaccine. In Bulgaria, Health Minister Kostadin Angelov also announced that the launch of AstraZeneca’s vaccine in the country could be stopped because people are not interested. The European Drug Administration – the European Union’s (EU) drug regulator – then recommended that countries continue to use vaccines as the benefits of vaccines far outweigh any potential risks. hidden from humans. Last week, the European pharmaceutical regulator listed clotting as an extremely rare side effect of the AstraZeneca vaccine. Some countries have started to re-use the vaccine after the suspension, but limited in the number of people vaccinated. As is the case in the UK, the country says it will offer another vaccine for people under the age of 30. While some countries are vaccinated with AstraZeneca, Thailand Health Minister Anutin Charnvirakul announced that the AstraZeneca vaccine will be the mainstay of the Southeast Asian country’s COVID-19 vaccination program. Mr. Anutin confirmed that Thailand has the expertise to closely monitor vaccine information and the decision is based on science. Thailand’s vaccination campaign mainly relies on domestically produced AstraZeneca vaccine and 2 million doses of Chinese vaccine to vaccinate about 35 million people, equivalent to 50% of the population – Thailand’s goal. must be reached by the end of 2021. Along with Thailand, Korea has decided to continue to vaccinate AstraZeneca for those who qualify. People younger than 30 years of age have not yet received the vaccine because the risk of blood clots outweighs the benefit of the vaccination. Continued reassurance and investigation of coagulation phenomenon after vaccination Health care workers give COVID-19 vaccine to people in Llanelli, South Wales (UK), April 9, 2021. Photo: AFP / VNA While countries are moving differently with the Johnson & Johnson and AstraZeneca vaccines, WHO continues to assert the benefits of COVID-19 vaccination. On April 15, WHO Director in Europe Hans Kluge reaffirmed that the benefits of the AstraZeneca vaccine outweigh the risks. “Make it clear that there is no doubt that the AstraZeneca vaccine is effective in reducing hospital admissions for COVID-19 and preventing severe illness that leads to death. The WHO has recommended this vaccine as soon as possible,” he said. as possible for adults to increase resistance to the SARS-CoV-2 virus “. WHO officials also pointed out that out of the 200 million people who got the AstraZeneca vaccine, there are only a few rare cases of a blood clotting disorder. He emphasized that the risk of blood clots in patients with COVID-19 is much higher than in those receiving the AstraZeneca vaccine. A study by scientists at the University of Oxford UK showed that COVID-19 patients have a higher risk of developing blood clots in the brain than those vaccinated against the disease. Data from over 500,000 patients with COVID-19 show that blood clotting occurs at an incidence of 39 out of 1,000,000 patients. Of the more than 480,000 people who received the COVID-19 vaccine made by BioNTech / Pfizer or Moderna, the incidence of coagulation was 4 / 1,000,000, while the rate was slightly higher for those receiving the vaccine. AstraZeneca – about 5 / 1,000,000 after the first injection. After the coagulation incident with the Johnson & Johnson and AstraZeneca vaccines, the researchers found that this rare side effect only occurs with vaccines using adeno virus vector technology (the virus that causes the common cold). There has been no record of coagulation in people who received the vaccine using other technologies from Pfizer and Moderna. However, the link between the technology using adeno virus vectors and coagulation is only a simple guess, there is no evidence. Russian vaccine has not caused any blood clotting cases and is increasingly “expensive”. Vaccine Sputnik V in Moscow, Russia. Photo: AFP / VNA When Western countries investigated blood clotting side effects, the Gamaleya Research Institute – which develops the Russian vaccine Sputnik V – said the vaccine has not caused any adverse reactions related to blood clotting. According to the Gamaleya Institute, there is no reason to equate the safety of the Johnson & Johnson, AstraZeneca vaccines with Sputnik V. All three of these vaccines are vector-based, using the adeno virus to deliver the protein of SARS-CoV- 2 into human cells, helping to stimulate the immune system’s response. However, all three manufacturers use different structures and technologies in vaccine formulation. Iran is the latest country to order Russian vaccines. Iranian Ambassador to Russia Kazem Jalali confirmed that the contract to buy 60 million doses of Sputnik V has been signed and completed, enough to give 2 doses to 30 million people. Ambassador Kazem Jalali also announced that Iran will receive the vaccine by the end of 2021. Russia is also transferring technology to produce this vaccine to a number of countries. Most recently, the Korean company ISU Abxis on April 15 announced an agreement with the Russian Direct Investment Fund (RDIF) on the technology transfer and production of Russia’s Sputnik V vaccine for Korean companies. . It is expected that the production of vaccine trials will soon be deployed at a facility in Yongin, south of Seoul. The Russian Sputnik V vaccine is the second most popular vaccine in the world approved for use by national pharmaceutical regulators.

On the market today, there are many sunscreen products, from domestic to foreign: Japan, Korea, China … with different indicators. It is the diversity of origin, origin, composition (used for dry skin, normal skin, combination skin) … that makes it difficult for consumers to choose suitable sunscreen products.

Moreover, in addition to sunscreen products with clear origins, many small shops, markets, websites … sell low-quality sunscreen products but imitate the prestige “brand”, popular.

Import sunscreen products

In recent days, the weather in the North is more sunny, peaking more than 40 degrees Celsius, consumer demand for sun protection products such as sunscreen, gloves, glasses, masks, especially anti-sun sunshine increased. This is also the time for low-quality sunscreen products to hit the market.

Walking around the market for students in Cau Giay (Hanoi), it is not difficult to see the areas selling cosmetics of unknown origin and labels. Remarkably, most products sold on the market are not preserved under the necessary conditions, away from direct sunlight.

Sunscreen is also sold on a variety of websites with different prices.

According to the survey, the prices of sun protection products in these markets are quite cheap, ranging from 70-100,000 VND / bottle, lower than in stores specializing in selling cosmetics from 50 – 100,000 VND / product. At first glance, the cosmetic products on the market have the same design, design, and design as genuine products, helping consumers’ eyes. Even for those with low incomes, this will be a popular product, suitable for money.

Sunscreen – the indomitable object on a hot summer day

As one of the indispensable products on a summer day, sunscreen helps people protect the skin, avoiding the effects of ultraviolet (UV) rays in the sun. Ultraviolet rays are divided into 3 types, UVA, UVB, and UVC rays. In which, UVA, UVB rays can pass through ozone layer and harm human health; UVC rays are blocked by the ozone layer, unable to penetrate the ground. Therefore, when going outdoors, our skin will be affected by UVA and UVB rays, which darken the skin, damage the skin, accelerate the aging process and increase the risk of skin cancer.

Sunscreen helps people protect the skin from the effects of ultraviolet (UV) rays in the sun.

To protect the skin from the effects of UV rays, consumers who choose sun protection products, including sunscreens, should pay attention to choosing a cream with a higher SPF number, which protects the skin from UV rays. higher. For example, SPF 2, skin protection ability is 50%; SPF 15, skin protection ability is 94%; SPF number is 100, the ability to protect the skin is 99%. However, consumers should not choose products with the SPF number too high, as it can cause skin irritation. Therefore, consumers only need to choose at 30, 50 for the best.

Besides, when buying a sunscreen, consumers also pay attention to the PA index (denoted PA ++, +++…) on the sunscreen. The more + sign, the better the resistance to UV rays.

However, consumers also note, it is possible that the sunscreen is suitable for one person, but irritates the skin for another. So, consider before choosing this skin protection product.

Experts warn against the harmful effects of sunscreen if used in the wrong way

Recently, the US Food and Drug Administration (FDA) recommends a sunscreen with a maximum SPF of 50-60 for the best skin protection. Two safe and effective ingredients in sunscreen are zinc oxide, titanium dioxide. Meanwhile, the ingredients aminobenzoic acid (PABA) and trolamine salicylate have been warned by the FDA to be unsafe.

FDA also requires manufacturers to demonstrate the safety of 12 sunscreen ingredients: cinoxate, dioxybenzone, oblulizole, homosalate, meradimate, octinoxate, octisalate, octocrylene, padimate O, sulisobenzone, oxybenzone, avobenzone. Therefore, consumers need to pay close attention to the ingredients on the product label when choosing sunscreen. Safe sunscreens approved by the FDA include sprays, oils, lotions, creams, gels, avocados, glues, ointments, and waxes. The agency says more information is needed before drawing a conclusion with its powdery sunscreen.

To prevent skin cancer, Associate Professor, Dr. William W. Huang, Wake Forest School of Medicine, recommends applying sunscreen about 30 minutes before going out in the sun and reapplying at least every two hours. Facial skin is a sensitive, vulnerable place to ultraviolet rays leading to skin cancer, so priority is given to applying cream on the face.

Ohio-based dermatologist Amy Kassouf also noted that sunscreen should be applied to small areas of skin like the eyelids, lips, and ears. Most lip cosmetics do not contain SPF. The skin on the edges of clothing is also often sunburned, so more sunscreen should be applied, according to dermatologist Jennifer Stein in New York. People with sensitive skin should use sunscreens containing zinc oxide and titanium dioxide in place of the chemical sunscreen ingredient.

According to chemist and founder of the beauty website The Beauty Brain – Perry Romanowski, expired sunscreens will no longer be able to protect your delicate skin. At this time, sunscreen, whether physical or chemical, has no longer reached the SPF level as advertised. Meanwhile, chemical sunscreens with ingredients containing oxybenzone, avobenzone and homosalate can oxidize and become less effective. Physical sunscreens contain zinc oxide or titanium dioxide, although there is no oxidation, they still lose the quality and effectiveness of sun protection. Simply put: while the sunscreen ingredients are active, they may not be able to function properly in skin protection.

Also sharing about the harmful effects of sunscreen, Dr. Erin Gilbert said that when you open the bottle of sunscreen with dirty hands, or open too many times can cause bacteria to enter the product. Decreases the quality of the cream and causes acne breakouts when used.

Dr. Gilbert recommends that if you leave sunscreen in a hot place such as in a car, swimming pool or in a bag, it will expire more quickly due to high temperature environments. In this case, you should replace it every few months to ensure that the sunscreen will always work effectively.

U.S. halts use of Johnson / Johnson vaccine

The implementation of johnson&johnson’s (J&J)one-dose Covid-19 vaccine was halted on April 13 when regulators announced they were reviewing rare cases of blood clots after receiving it. The move could prompt thousands of people expected to get the J&J vaccine this week to find an alternative.

The Food and Drug Administration (FDA) and the U.S. Centers for Disease Control and Prevention (CDC) both recommend halting the distribution of the J&J vaccine after recording 6 cases of cerebral vein sinus thrombosis (CVST).

Symptoms are noted in women between the ages of 18-48 and appear 6-13 days after the J&J. vaccine injection. “Among cases of coaalysis in the U.S., one person has died and one patient is in critical condition,” said Peter Marks, head of the FDA’s Center for Biological Research and Evaluation.

However, stopping the use of the J&J vaccine in the US when there are only a few cases of blood clots has raised questions about over-reactions.

Speaking at the White House on April 13, Dr. Anthony Fauci, Director of the National Institute of Allergy and Infectious Diseases, said that the CDC and FDA have acted “with extreme caution” and stressed that the decision to recommend stopping the use of the J&J vaccine is only temporary.

“I don’t think they made the decision in a hurry,” Mr. Fauci said.

Despite this, the move left those planning to get the J&J vaccine confused and raised concerns that it could cause hesitation over covid-19 vaccination.

Earlier, 15 million J&J vaccines were damaged due to production errors at a factory. In Colorado, three mass vaccination points stopped using the J&J vaccine last week after 11 people reported symptoms of nausea and dizziness after receiving the vaccine.

For regulators, halting the use of the J&J vaccine has made it difficult to meet the urgent need for vaccines during the pandemic. When investigating the issue, U.S. officials must also try to maintain public confidence in the vaccination program. The suspension of J&J vaccination shows that regulators are taking potential issues seriously, but if they can’t find an answer yet, it could make people more concerned about vaccinations.

Link between J&J vaccine and cerebral vein sinus thrombosis

Cerebral vein sinus thrombosis (CVST) is a condition in which blood clots are formed in the veins and sinuses of the brain. This is a rare form of a stroke. In the general population, this symptom occurs in about 5 out of 1 million people. Symptoms of CVST include headache, blurred vision, convulsions, and loss of body control.

However, there are a number of factors that cause regulators to pay attention to cases of CVST after a single dose of J&J. Mr. Marks explained that, patients with blood clots also have tinglet reduction, the condition of tinglets in the blood decreases to very low levels, leading to bleeding and bruising. The combination of blood clots and low tinglets prevents patients from using common anti-coaculation treatments such as heparin, a blood thinner. That’s why health officials want to halt J&J.J. vaccinations until concerns can be investigated and give new guidance if necessary.

In addition, another factor is the cases of blood clots that occur in young women, who usually do not face a high risk of suffering from this disease.

The suspension of the J&J vaccine has been reminiscent of many European countries suspending all or part of the Covid-19 AstraZeneca vaccination program due to fears of blood clots. In March, the European Medicines Regulator (EMA) halted distribution of the AstraZeneca vaccine before allowing it to continue. Later, regulators concluded the AstraZeneca vaccine did not increase the risk of blood clots.

“This is a safe and effective vaccine. The benefits of vaccines in protecting people from the risk of dying and hospitalization from Covid-19 are far greater than the possible risks,” EMA Executive Director Emer Cooke said at a press conference in March.

Both the AstraZeneca vaccine and the Johnson /Johnson vaccine are based on modified adenovirus vectors. Adenovirus is a separate virus designed to provide DNA instructions to cellsto make the mutable protein of SARS-CoV-2, the virus that causes Covid-19.

Nearly 7 million people in the U.S. who have been vaccinated with the J&J. Vaccine AstraZeneca are still under review and have not yet begun distribution in the U.S., even though the country’s government has purchased millions of doses of the vaccine.

The link between the J&J vaccine and symptoms of cerebral vein sinus thrombosis has not yet been clarified, but Vox has made several assumptions.

“Mutant proteins are produced using instructions from vaccines,” said Robert Brodsky, Director of hematological division at Johns Hopkins University. In some cases, mutating proteins can trigger the response of the immune system. That immune response can also damage the tinglets, causing symptoms such as blood clots.

In addition, if a spike in a protein can trigger this reaction, it is likely that the virus is intact that can also activate CVST in vulnerable people.

Rare complications that create major public health challenges

The Covid-19 vaccine has been tested on tens of thousands of people in clinical trials, and all three licensed vaccines in the U.S., Moderna, Pfizer/BioNTech, and Johnson & Johnson have all been proven safe, with levels of side effects being mild to medium.

But as the number of people taking part in vaccine trials increased from thousands to millions, rare complications began to appear.

That happened to Pfizer/BioNTech after the vaccine was distributed to the market. Some people after vaccination experience a severe allergic reaction to the Pfizer vaccine. Similar problems also appeared with the Moderna vaccine. In January, the CDC estimated that the rate of allergic reactions to the Pfizer/BioNTech vaccine was 11.1 per 1 million vaccinations, while the rate of the Moderna vaccine was 2.5 per 1 million vaccinations.

Health officials have revised the vaccination process to screen people with a history of severe allergies. They also asked the person after vaccination to stay for 15 minutes for monitoring, as most allergic reactions occur during that time period.

Regulators can add screening criteria for people at higher risk for blood clots before getting the J&J vaccine.

It’s too early to say whether regulators will do the right thing when it comes to halting J&J vaccinations. Studying potential vaccine issues can boost people’s confidence in vaccinations, but can also cause confusion and fear of complications, making more people more vigilant.

What about those who have received the J&J vaccine?

Dr Fauci said that, for those who had received the J&J vaccine more than a month ago, they didn’t need to worry. However, those who have recently received the J&J vaccine and begin to have symptoms associated with cerebral sinus thrombosis should inform their doctor. “6-13 days after vaccination will be the time of symptoms,” Mr Fauci said.
