Researchers found that people who made antibodies to the coronavirus were much less likely to test positive again for up to six months and maybe longer. The institute's study had nothing to do with cancer - many federal researchers have shifted to coronavirus work because of the pandemic. Only 0.3% of those who initially had antibodies later tested positive for the coronavirus, compared with 3% of those who lacked such antibodies. Cases of people getting Covid-19 more than once have been confirmed, so "people still need to protect themselves and others by preventing reinfection."
