Even if I ALREADY had Covid, I should STILL get vaccinated, because we don’t know how long natural immunity lasts, and we also don’t know how long vaccine immunity lasts. And I should get the vaccine to keep a vaccinated person from catching Covid from me, but even if I get the vaccine, I can give it to the vaccinated person anyways. And, the other vaccinated person can still easily catch a serious case of Covid from me and die. Do I have all that right?
