I'm not an expert, but common sense says no. It's a virus, so think flu. Once you kick it, you should be done with that strain.
The "flu shot" is reformulated every year based on mutations as well. This will be the same type of deal. Also, you can't hide behind a mask forever. Everyone WILL eventually be exposed.
FWIW, I have heard of doctors recommending to take it as well as advising to NOT take it.
