You don’t need to be exposed to large viral loads to build immunity, you can actually build immunity with very limited exposure as long as the immune system is activated to some extent. Exposure level determines the severity of the illness, masks allow people to limit their exposure without hermetically sealing them off from all exposure entirely. Less sick, same immune response.
