Do contact with the virus work as booster shots for vaccinated/recovered people?
gpt
Kind of. The shot results in a predictable dose of antigen exposure, response, and zero risk of actual infection.

An exposure to the virus will absolutely provoke a response that will have a “booster” effect, but how much of a response will vary tremendously based on the nature of the exposure, and there’s obviously a risk of infection. Even asymptomatic infections cause tissue damage in lungs, so one would want to avoid that, if possible.

The booster effect exists in both cases, but they are not equivalent in safety, magnitude, or consistency.
