We are talking about the duration of protection of the Pfizer vaccine against the Omicron variant, but what about the protection of people who have received the AstraZeneca vaccine?

Whether you have been vaccinated with the Pfizer, Moderna or AstraZeneca vaccine, Public Health recommends that you get your booster dose today. The vaccination for this third dose has been extended since January 4 and by the end of the month, all adults aged 18 and over will be able to make an appointment on the Clic Santé platform.
Where the information is less clear is if, in addition to your two doses of vaccine, you have been infected with one or the other of the variants, either Delta or Omicron.
Clearly, being infected has allowed your metabolism to make antibodies. But how long will these antibodies be effective? What if you have been infected with the Delta variant, will these antibodies protect you against the Omicron variant?
You see, there are still a lot of unanswered questions. All the specialists we consulted told us the same thing: we must give time to time. In January, research will be undertaken to learn more about the protection induced by infection and the persistence of this protection. Until science is more precise on this subject, it is therefore recommended to get the booster dose, allowing a period of three months, or at least eight weeks, to pass. after the time of infection.
