(KFOR NEWS October 8, 2021) A study published this week found that the Pfizer COVID-19 vaccine begins to weaken after roughly two months.
A study published in the New England Journal of Medicine found that protection began to drop off after that point – although protection from severe disease, hospitalization, and death remained strong.
The study also found that people who were infected and recovered from COVID-19 before getting the vaccine had stronger resistance.
Pfizer’s vaccine is the only one so far to get full authorization from the FDA.
