Reply To: I took the 2 shots & 1 booster should i take the next one ?

It isn’t really so beneficial but it won’t really hurt. I’d say nothing to lose but not really necessary. But I’m not a doctor. Ask your doctor. Parenthetically, I assume everyone here understands the concept of emuna and that these types of discussions are regarding the proper hishtadlut one should perform. No need to point out it’s all up to Hashem which is, of coarse, a given.
