Pfizer, Moderna vaccine protection can last for months – or more

June 28, 2021 – COVID-19 from Pfizer and Moderna vaccines can protect against coronavirus for months – and much longer for those who had been infected and were subsequently vaccinated, according to a new study.

The study, in the journal Nature, says either vaccine provides robust protection for at least 12 weeks after a second dose and could provide low-level protection for at least a year.

The researchers say their study showed the vaccines offer “robust and prolonged” protection.

The New York Times reported that the researchers on this study and others suggest that COVID-19 immunity could last for years, or even a lifetime, in people with the disease who are cured and vaccinated.

The researchers, led by Ali H. Ellebedy, PhD, of the Department of Pathology and Immunology at the Washington University School of Medicine in St. Louis, warn that variants of the virus that emerge in the future could alter the effectiveness of the drug. vaccines.
