Zweedse onderzoekers vinden dat mensen met milde of asymptomatische Covid-19 T-cell immuniteit hebben ondanks dat ze niet positief testen voor de aanwezigheid van antilichamen.

“A new study from Karolinska Institutet and Karolinska University Hospital shows that many people with mild or asymptomatic COVID-19 demonstrate so-called T-cell-mediated immunity to the new coronavirus, even if they have not tested positively for antibodies. According to the researchers, this means that public immunity is probably higher than antibody tests suggest.”
