“If not RCT at least vaxxed vs unvaxxed retroactively”
If you read my comments you would know such a study HAS been done see the Philippines study cited above.
And of course RCT blinded placebo trials have been done
starting with the early Salk POli vaccine
down to the MMR which this thread is about :
Frequency of true adverse reactions to measles-mumps-rubella vaccine. A double-blind placebo-controlled trial in twins. Lancet. 1986 Apr 26;1(8487):939-42.
There , now you have placebo studies. Satisfied? (Don’t worry I’m not holding my breath)
“All you are saying that because the government says BELIEVE me that its safe without any studies to back it, i have to belive it ..”
not once have I said that.
So not only don’t you bother to read comments I write, you put other words in my mouth
