Effectiveness of Pfizer’s COVID-19 Vaccine Wanes 6 Months Post-Injection

Pfizer’s COVID-19 vaccine effectiveness drops to 84% 6 months after the vaccine series is complete, raising the question about whether a booster shot is needed.

This report, which has yet to be reviewed by an outside scientific panel, determined that the initially stated efficacy rate of 96% drops to 84% after 6 months. The highest level of effectiveness occurred 2 months after completion of the vaccine series. The data set includes more than 44,000 test subjects. However, the vaccine’s ability to protect against severe illness remained high, at 97% even 6 months post-inoculation. Click here to read more.
