This is how the immunity acquired by the Pfizer vaccine weakens over time

A new studio on Pfizer / Biontech’s COVID-19 vaccine efficacy revealed that protection against the vaccine-generated virus drops to approximately 84 percent four to six months after receiving the second dose.

The survey, funded by the same company, found that the vaccine’s effectiveness was 96.2 percent stronger after a month or two after receiving the second dose.

The studio it also showed that the effectiveness decreased in media by 6% every two months and the vaccine was tested on more than 44,000 volunteers, and it appeared that after four months the effectiveness dropped to 83.7% in the majority of fully vaccinated individuals. .

The financing of the studio he arrives in one moment in which Pfizer is pressing for approval to administer a third dose of its vaccine to increase protection against the virus, which US health officials have opposed. At present, the Centers for Disease Control and Prevention (CDC) along with the Food and Drug Administration (FDA) do not recommend booster doses for fully vaccinated individuals.

“Fully vaccinated Americans don’t need a booster dose in this moment, “said the Department of Health and Human Services (HHS) in a press release. He explained that the Food and Drug Administration, the Centers for Disease Control and Prevention and the National Institutes of Health are participating in a rigorous scientific process to assess if and when a booster dose is needed, according to US channel FOX.

According to the data, if the effectiveness of the vaccine continues to decline at a rate of 6%, protection against the virus will be 50% approximately 18 months after full vaccination.

The studio also showed that despite the reduction, the vaccine was 97% effective against severe symptoms for at least six months.
