In mice, a kind of immune memory appears to protect the cells against future harm, a finding that could provide insight into treatments for irritable bowel syndrome and other inflammatory digestive conditions.
Half a year after infection, people who had recovered from COVID-19 had robust antibodies, along with traces of the virus in their gut, which may drive long-lasting immunity.
Studies on SARS-CoV-2’s milder cousins hint that our immune systems are quick to forget the viruses, but it’s unclear whether the same is true for the agent that causes COVID-19.
Two studies present biological evidence that measles infections in unvaccinated children wipe out immune memories of other pathogens, putting the kids at risk of other deadly diseases.
