Those who were infected and survived a battle with the coronavirus disease 2019 (Covid-19) should make sure they also get immunized with the vaccine for the virus.

“They will be asked to stand in line and get a vaccine also,” said Dr. William Schaffner, a professor of infectious diseases at Vanderbilt University Medical Center in Nashville, Tenn. “There will be no distinction made, in part because we think there’s no adverse event that will occur, and also the protection from the vaccine actually may be more long-lived, of longer duration than that you get from the natural infection.”

Coronaviruses are notorious for prompting a flawed and incomplete immune response in humans, infectious disease experts say.

It’s one reason why science has yet to come up with a cure for the common cold.

“With the four seasonal beta coronaviruses that circulate and cause all the upper respiratory infections you see in your practice, those people lose immunity in months to a year or two,” said Dr. Gregory Poland, director of the Vaccine Research Group at the Mayo Clinic in Rochester, Minn. “That’s why people fall prey to the common cold again and again.”

The body uses a relatively simple strategy to fight off common cold coronaviruses, and this strategy does not appear to make a lasting impression on immune system memory, Poland said. SOVEREIGNPH
