Coronavirus immunity probably significantly higher than tests suggest – BelfastTelegraph.co.uk
The number of people who have coronavirus immunity could be higher than antibody tests suggest, a new study indicates.
Research from Karolinska Institutet and Karolinska University Hospital shows that many people with mild or asymptomatic Covid-19 demonstrate so-called T-cell immunity to the disease.
This is even if they have not tested positive for antibodies to the virus.
