COVID Vaccines Lose Effectiveness Within 6 Months- UK Research Reveals

According to researchers in Britain, protection against COVID-19 offered by two doses of the Pfizer/BioNTech and the Oxford/AstraZeneca vaccines will wane within six months, underscoring the need for booster shots.

Studies have shown that after five to six months, the effectiveness of the Pfizer jab at preventing COVID-19 infection in the month after the second dose plummeted from 88% to 74%.

For the AstraZeneca vaccine, effectiveness fell from 77% to 67% after four to five months.

The updated analysis was based on data from more than a million app users during the period December 8, 2020 to July 31, 2021, comparing self-reported infections in vaccinated participants with cases in an unvaccinated control group.
