Covid Antibodies Fade Rapidly, May Not Offer Lasting Immunity

For those who were attacked with mild Covid symptoms they have to be cautious regarding so-called herd immunity as the loss of antibodies occurred more quickly than with SARS, an earlier type of coronavirus infection. While the protective role of antibodies against infection isn’t fully understood, they are generally considered a good representation of some protection against infection in general.

A recent study from King’s College London showed that the level of antibodies may drop to a degree that makes them undetectable as soon as three months after infection. However, the body also mounts other forms of immunity responses, including from so-called T-cells, which appear to play a role in protecting against reinfection with Covid-19.
