Is the sound form the 80's god. Yeah if you recover from the infection its cuz your immune system fought and killed the virus. When it does that it learns about the virus and how to defend its self against it in which you get immunuty but the problem now is that no one knows how long the immunuty stays with you it could be a week, month or year. More research is needed to determine the duration. And yeah the vaccine gives you immunuty.

The best n reliable way of defending oneself from pathogens is get infected n develop a specific antibody to fight for secondary infection which we call it natural acquired active immunity. This works for Covid 19 too but the problem is the half life of the antibodies produced against z virys, for how long they gonna stay n fight for us? Still unresolved question. About vaccines its part of artificially acquired active immunity which contains so many substance including the attenuated virus which alerts our body to prepare antibodies pro-infection tho there may be side effects against those chemicals inside.
