Research: Coronavirus antibodies may last just a few months

The most recent research on this topic, however — published this week in The Lancet — suggests that one in five people studied lost detectable levels of antibodies within five weeks.

The study tested 60,000 people in Spain for antibodies three times between April and June. About 7% of the participants who had antibodies during the first phase of the study (April 27 to May 11) no longer had them in the second phase (May 18 to June 1), according to CNN. About 14% of participants who had antibodies during the first stage no longer had them by the third phase (June 8 to 22).

Loss of immunity was most common among people who never developed symptoms, Reuters reported.

“Immunity can be incomplete. It can be transitory. It can last for just a short time and then disappear,” Raquel Yotti, one of the study’s coauthors, said during a news conference.
