According to a Vietnam News Agency correspondent in London, Oxford University in the UK has decided to expand research into the combined use of COVID-19 vaccines to evaluate whether this vaccine mix is safe and helps prolong the free time. epidemic in vaccinated people or not.

In February 2021, a team of vaccine researchers at Oxford University started a study called Com-Cov, in which volunteers are given the first and second shots with two different vaccines. are Oxford / AstraZeneca and Pfizer. Now, the researchers will add Moderna and Novavax vaccines to the pilot program.
Matthew Snape, Associate Professor of Pediatrics and Immunization at Oxford University and lead the study, said the focus of the study was to find out if the available COVID-19 vaccines could be used. more flexibly, with the use of one vaccine for the first shot and another for the second shot, or not.
Associate Professor Matthew Snape expects that if research can prove that the mixed vaccination produces the same immune response as the standard vaccination and does not significantly increase the response to the vaccine, there will be more. people completing the COVID-19 vaccination plan earlier. This will also assist the health system in responding to a shortage of any vaccines currently in use.
To expand this study, researchers are looking for more volunteers over the age of 50 who have received their first shot of the vaccine in the past 8 to 12 weeks. Volunteers, who received their first shot with the Oxford / AstraZeneca or Pfizer / BioNTech vaccine, will be randomly assigned to receive a second shot with the same first shot or with the vaccine. Made by Moderna or Novavax.
