Pfizer vaccine efficacy wanes three months after second dose

Experts who have been investigating vaccine effectiveness have found that risk of infection rises the longer it is since people received the second dose of the Pfizer/BioNTech Covid-19 vaccine.

Experts from the Research Institute of Leumit Health Services in Israel found a gradual increase in the risk of Covid-19 infection from 90 days after the second Pfizer vaccine.


Their findings showed that the vaccine “provided excellent protection in the initial weeks after vaccination but suggest that protection wanes for some individuals with time”.

Experts have concluded that it appears clear that immunity wanes after the first three months of being fully vaccinated.

“Large scale Covid-19 vaccination campaigns can achieve control over the spread of the virus, but even in countries with high vaccination rates, breakthrough infections can occur,” the experts said.
