According to a study published in the British Medical Journal, Pfizer vaccine efficacy begins to wane three months after the second dose was administered.

The team of experts stated that the study supports the idea of booster vaccines being rolled out.

Experts from the Research Institute of Leumit Health Services in Israel found that the risk of getting Covid-19 gradually increased 90 days after receiving the Pfizer/BioNTech vaccine.

Although the study, which involved 80,057 people across all ages, was predominantly observational, experts stated that it’s clear that immunity wanes three months after receiving the second vaccine dose.

The group stated, “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.”

-AD-

AstraZeneca stated that antibody protection from its vaccine also wanes although it’s thought that the jab offers long-term T-cell immunity for older people, according to CEO Pascal Soriot, which may be better than other vaccines.
