>So the amount shed is too low to infect anyone beyond 9-10 days (I think, I am not a virologist, etc.)
Is it possible to acquire immunity against the virus (in a similar way that vaccines work) by being in contact with someone at say day 20+?

There is also a similar theory that cloth masks might have the unintended positive side effect of building immunity. They are not perfect, so the virus might still reach its target. But the viral load could be reduced enough that instead of infection it leads to immunity.
