An Instagram post highlighted a headline about a non-peer-reviewed study from Israel that found that unvaccinated people previously infected with SARS-CoV-2 had greater immunity against the delta variant than never-infected people fully vaccinated with Pfizer/BioNTech’s COVID-19 vaccine.

Researcher Distorts Facts on COVID-19 Vaccine Approval, Liability

The Pfizer/BioNTech COVID-19 vaccine was fully approved by the Food and Drug Administration, though an emergency use authorization also remains in place.
