First seen Apr 22, 2026 · Last updated May 23, 2026 · Updated 8 times
Summary
This study looked at whether people infected with COVID-19 who never had symptoms still develop antibodies (immune response) compared to those who had symptoms. Researchers followed over 200 adults from households with a confirmed COVID-19 case. The goal was to understand if silent carriers can spread the virus and whether they build immunity.
