The studies that have linked vaccinations to autism have been proven to be frauds. Not only that, but those who do not innoculate their children, and allow diseases that could be eradicated to survive, can probably be considered rodfim. The eintire humanity will suffer when these diseases make a comeback in the children that are not protected.
I say this with all due respect to gedolim like Rav Shmuel Kamenetsky and family who are extremely anti vaccination, and into all kinds of natural health products. Yes, I know its hard to argue with the relative health that many in that family enjoy even at advanced ages, tavo aleihem bracha, I think that may be a special zechus that Hashem gives them. Plus R’ Yaakov’s genes surely don’t hurt either!
I know a family that was recently meshadech with an einikel of Rav Shmuel. Rebbetzin Kamenetsky told the mechutenes, “We’re so happy to be associated with your family!” At first they got all excited about such a warm approval from such a distinguished rebbetzin. Rebbetzin K then said, “I’m really happy that you don’t do vaccinations.”
Even so, that entire philosophy has recently been proven to be based on fraudlent research.
