Antibody protection after mild COVID-19 may not last; an estimated 100 mln people have had long COVID

The following is a summary of some recent studies on COVID-19. They include research that warrants further study to corroborate the findings and that has yet to be certified by peer review.

Among 43 Australians who dealt with mild COVID-19 early in the pandemic, 90% still had antibodies 12 months later.
