A new Chinese study shows that people who develop antibodies after becoming infected with the coronavirus may not keep them more than a few months, especially if they showed no symptoms to begin with.

Previous studies had found that most people who became infected developed antibodies. Health departments around the world give antibody tests as a way to prove a person has already had the coronavirus.

The findings call into question the idea of “immunity passports,” which some countries want to issue to people who test positive for antibodies. These people would be allowed to go back to work and travel because they’re supposedly immune to the virus.

“Together, these data might indicate the risks of using COVID-19 ‘immunity passports’ and support the prolongation of public health interventions, including social distancing, hygiene, isolation of high-risk groups and widespread testing,” the authors of the study wrote.
