Greetings from the Greek Isles and a special shout out to Binyamin.
While I’m not sure if being called a “Hellenist” is sort of like being designatd an upscale apikores, I go back to a simple point that in matters of public health such as vaccination against highly infectious diseases, our primary sources of guidance are medical and public health professionals, not a rav or posek, no disrepect to the latter. If something about the medical advice we receive raises a red flag, than certainly discussing it with you R/P may be warranted and he may offer some useful guidance as to reconciling that advice with halacha. If the Rav himself is not also a medical professional, it was be malpractice for him to render medical opinions. We are not like the goyishe lunatics who refuse medical care, transfusions etc. because doing so might contradict their misguided notion of hashgacha paratis (i.e. if you are sick its (R’L) “God’s will” and seeking medical intervention is to disrupt “God’s” will. Even if you want to put yourself and your own family at risk by foregoing recommended vaccinantion s (with the concurrence of your R/P), you have zero right to project your foolishness on the rest of the Tzibur and place others at risk.
Having said that, hoping all the CR family including UB) stays well and is up-to-date on the ir shots.
