There’s a chance coronavirus vaccine may not provide immunity for very long: Fauci

White House health advisor Dr. Anthony Fauci said he worries about the “durability” of a potential coronavirus vaccine, saying there’s a chance it may not provide long-term immunity.

If Covid-19 acts like other coronaviruses, “it likely isn’t going to be a long duration of immunity,” Fauci, director of the National Institute of Allergy and Infectious Diseases, said during an interview Tuesday evening with JAMA Editor Howard Bauchner.

“When you look at the history of coronaviruses, the common coronaviruses that cause the common cold, the reports in the literature are that the durability of immunity that’s protective ranges from three to six months to almost always less than a year,” he said. “That’s not a lot of durability and protection.”
