Jalimon, first we have to confirm whether or not one can gain immunity to covid or if it’s a recurring type infection like the common cold or gonorrhea. There are currently about 200 cases of reinfection in S.Korea. One of the possible explanations is that those 200 just didn’t mount enough of an immune response the first time. The other is much less preferable which is that you can’t gain immunity at all. If they do conclude that immunity is not possible, I would snatch up some Gilead stock REAL QUICK.
