Would you say that the government telling those people that they should be afraid of vaccines will help or hurt in this case?
I don't think people base their beliefs purely based on what the administration says
the whole rollout and lockdowns, Fauci, etc. were a perfect storm to cause skepticism towards vaccines
I gotta be honest, I don't really think these immigrant groups see or care what Trump/RFK are saying. If anything they see them as an "enemy" who they should not trust.. This is an incredibly left-leaning city where the majority of public health information (or any other messaging) being disseminated is counter to what the current federal admin is saying (as a rule, it seems).
So to answer your question, I don't personally think it helps or hurts in any significant amount relative to other cultural drivers.
