There's been like 3 confirmed of that actually happening and last I checked they didn't experience any symptoms.
There was some story just this last week talking about a 2nd case in the U.S. but it was from back in May? Weird they ran it now...jealousy?
From what I can tell the 'immunity' for these viruses is basically the T-cells keeping it from doing much a 2nd time. Even with a flu shot, you might get infected, but just not badly. The big question imo is how contagious someone may be if they get it again.
This past week, researchers reported cases of reinfection in a patient in Hong Kong and two patients in Europe; but in all three cases, the patients either developed a milder form of COVID-19 or were asymptomatic the second time around, according to NBC News.
But according to the new case study, the 25-year-old Nevada patient developed more severe symptoms the second time he was infected. His case was published as a preprint on the Social Science Research Network (SSRN) and hasn't yet been peer-reviewed. The researchers have submitted their paper to the journal The Lancet Infectious Diseases.
