The researchers’ findings were posted on a preprint website ahead of peer review and suggest that people under 30 may be less protected against a second infection.
“I know a lot of people think, ‘I had COVID, so I don’t need to get a shot,’” says John Alcorn, Ph.D., a professor of pediatrics at the University of Pittsburgh School of Medicine and UPMC Children’s. Pittsburgh Hospital.

“But this study suggests that some patients, particularly young people, do not have particularly good antibody memory after infection, indicating that immune boosting with vaccination is important for these people.”
Alcorn, the senior author, said it’s not clear why young people had the lowest antibody levels, but while their findings suggest that the severity of the disease can affect a person’s level of protection, it doesn’t explain everything.

UPMC said Alcorn and his team plan to follow up the same patients to measure how neutralizing antibodies change over time, as well as compare antibody levels in those who did and did not receive the injection.
