Sam,
You will notice that I did not react to Health’s comments even though I don’t agree with them, because he was disagreeing with their shittah. However ZDs comment was not arguing with the shittah, it was a childish attempt to belittle Gedolim. And that’s why I paraphrased it in my comment to him. Specifically because it is something he does often.
I think there is a matter of Halacha in debating the risks. There is no question that there are risks to the vaccines, the question is how great. And if a parent weighs the risks of vaccination vs no vaccination and the likelyhood of contracting disease while not vaccinated vs contracting it even when vaccinated, then it is a halachick shailah if the person is considered a mazik and if a school has rishus to exclude a child because of that.
That’s also why it’s not comparable to testing for Tay-Sachs as one of the commenters above thought they were being wise raising, because there is no danger at all in being tested for Tay Sachs.
I know you see the difference.
Shabbat shalom.
