@chaimmayer We are going around in circles, and there is inherently a lot of circular logic here. But consider this, and this addresses
@mmgfarb point as well. Of course doctors are not all knowing creatures, and of course if you don't have Ruach Hakodesh you can't know facts not presented. But we trust the vast body of doctors scientists, regulators and government agencies to make determinations on our behalf, due to the vast amount of data and evidence available to them.
Let's use GMO's as an example. There is no real science that they are unhealthy. It's something people have done naturally for thousands of years, and now it's being done scientifically, in a lab, with exacting results, which is admittedly scary. However, GMO's are enabling thousands of lives to be saved by having sturdier seeds in extreme third world countries, and so on.
If the government agencies that are allowing this to go on were mere puppets in the hands of industry, as the anti-GMO's claim, and they're really life threatening and dangerous, don't you think that there would have been some sort of mass epidemics across sub saharan africa? Shouldn't there be a stronger incidence of cancer in fast food workers becasue they spend so much time near microwaves? and so on and so on.
Halacha tells us that these governmental agencies have the authority of a Beis Din when it comes to enacting health and safety regulations, and they were talking about much less transparent governments than the USA. (Aruch Hashulchan, Rav Nosson Gestetner, et al). Not because they are all knowing, they aren't, and they admit that. But because they, to the best of current methodology, have determined these products to be safe. And that includes vaccines.
I could go on, and I've given up on farkoifte anti vaxxers. But what I tell people is this:
Kids are dying and getting really sick from measles. I don't know if you've known people who had polio as a child, but I do. When they survive with lungs intact, the rest of their life is still misery. Generally they didn't survive.
We tend to not be aware of how terrible some of these diseases are because they aren't common. But vaccinations have saved untold millions of lives. There were, and even possibly still are issues, but most have been addressed, and there is a ton of circular and quack science out there. It's not about Eastern vs western, I'm all for some alternative medicines. It's about responsible medicine. To blanketly and uncompromisingly not vaccinate is, in my opinion, totally irresponsible. You can slow down the schedule, etc. But it should be done with medical advice, and by all means, find a doctor who understands your perspective. But just like you wouldn't avoid cancer treatment because of your hergesh (I hope, some people would, and are rotzchim beyadeim mamash), this should be no different.
And when it comes to poskim, all the big rabbonim always said to follow conventional medical wisdom. That is our chiyuv hishtadlus. Even if there are some outliers, none will sign a paper that says not to vaccinate, (the psak you sent doesn't say that either), and that isn't normative halacha.
I said my piece, unwillingly. I wish you much siyata dishmya in your decision
