t cells are meant to provide twice the immunity compared to antibodies but they aren't detected in antigen tests. maybe some new type of test maybe developed...There's bad news on the herd immunity front too,according to the Spanish there's very few people have any antibodies and the lancet has backed this by studying other countries where the virus is rampant .SD is all they can recommend..
