(((WTAJ) — A new study conducted on the efficacy of Pfizer’s COVID-19 vaccine shows that protection against the virus drops to about 84% about 4-6 months after the second injection.
In Company-funded surveyThe efficacy of the vaccine was found to be the strongest, 96.2%, between 1 week and 2 months after receiving the second dose. The study also showed that efficacy decreased by an average of 6% every two months. Tested with more than 44,000 volunteers, at 4 months, the efficacy of most fully vaccinated individuals was found to drop to 83.7%.
This study has not yet been peer reviewed.
The study is being funded as Pfizer is promoting a third dose of COVID vaccine to enhance immune protection. This is a veto exercised by US health authorities. Currently, the US Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA) do not recommend boosters for fully vaccinated individuals.
“Fully vaccinated Americans do not need booster shots at this time. The FDA, CDC, and NIH are science-based to determine if or when boosters are needed. We are working on a rigorous process, “said the Department of Health and Human Services (HHS). In a press release..
According to the data, if the effectiveness of the vaccine continues to decline at a rate of 6%, the protection against the virus will be 50% about 18 months after full vaccination.
The study also showed that the vaccine was 97% effective against serious illness for at least 6 months, albeit with a decline.
