I am just guessing here, but I think the gadol they are referring to is Rabbi Shmuel Kaminetsky, Shlitah.
I did have my children vaccinated. When I first heard about anti-vaxxers I thought they were paranoid.
But then I saw my nephew regress into autism after receiving 7 vaccines in one day.
And I have been doing research for a couple of years now. And I learned about CDC corruption.
And debating provaccers who lie further strengthens my position. Like ProVaxxers who go around
lying there are NO studies linking vaccines to autism except for “Wakefield’s Fraudulent Study.”
Regardless of whether or not you accept those studies it is an absolute LIE to say There aren’t any
studies showing a link between Autism and Vaccines. And that’s just one example.
