How do you recover from a virus if not by becoming immune to it? Immune here in the sense of being able to fight it, not in the sense of being unaffected (the letter will clearly not happen, nor does it need to).
Ok, how long does that immunity last? Is it forever? Is it two months? Can we actually achieve herd immunity or would we be signing up for a reinfection merry-go-round?
> This is not true, nor a generally good guideline to think about things. Coronaviruses generally confer short immunity periods.
would the common cold be a good example? the common cold is caused by a few different coronaviruses, and it's not uncommon for people to get a cold at least once a year or even multiple times a year.
You're right, every disease we catch gives us complete immunity. That's why when you catch the flu once, you're immune to it forever.
I'm being sardonic here because you have a severe misunderstanding of how immunity and our immune system actually works. Some diseases (like the chicken pox) we never truly beat, it just becomes latent. Other diseases we only become briefly immune.
