Mutated virus may reinfect people already stricken once with covid-19, sparking debate and concerns
In the placebo group of the trial for Novavax’s vaccine, people with prior coronavirus infections appeared just as likely to get sick as people without them, meaning they weren’t fully protected against the B.1.351 variant that has swiftly become dominant in South Africa.
About 30 percent of the people in the South African trial had antibodies in their blood at the start of the trial showing they had recovered from an earlier infection.
But that previous exposure didn’t necessarily appear to afford protection. Among those who got saltwater shots, the people with a prior infection got sick at the same rate as study participants who had not been previously infected — a surprise because they would have been expected to have some immunity. Nearly 4 percent of people who had a previous infection were reinfected, an almost identical rate to those with no history of infection.
