Protection against covid in vaccinated people decreases in six months


Protection against COVID-19 infections in people fully vaccinated with the AstraZeneca and Pfizer preparations begins to decline in about six months, according to the results of a study released Wednesday.

The results released today by experts in charge of the Zoe Covid investigation revealed that the protection of the vaccine developed by Pfizer / BioNTech, which protected 88% against the virus one month after the administration of the second dose, was decreasing to 74% between 5 and 6 months after the second injection.
