Pfizer’s COVID-19 immunity protection diminishes after 2 months, and it can reach as low as 20% after 4 months: studies
  • Two recent studies found that Pfizer’s immunity protection diminishes rapidly a few months after a person has their second dose.
  • However, one study noted that the vaccine’s protection against death and hospitalization still remained as high as 96%.
  • The studies affirm Pfizer’s earlier comments that its vaccines may not defend against COVID-19 infection as effectively over time.

COVID-19 immunity protection from two doses of the Pfizer vaccine starts dwindling after about two month, still, the shots remain effective in guarding against hospitalization and death, according to a pair of studies published in the New England Journal of Medicine on Wednesday.

The new findings affirm what Pfizer, Moderna, and the Centers for Disease Control and Prevention have indicated in recent weeks – that the vaccines’ ability to protect the body from coronavirus infection may wane over time. Last month, the Food and Drug Administration authorized Pfizer booster shots for older or more vulnerable people.
