Agree ransomnote.
But can an argument be made that the most prone to chronic ailments are the most likely to need the vaccination? Thus those showing most chronic diseases would be the vaccinated.
I agree the truth is kept from those who need information to make an educated decision.
The litigation compares the general vaccinated public - like school vaccination schedules etc. with those who did not attend public schools or follow CDC guidelines, so it doesn’t filter for people more likely in need of vaccination - it is blind in that respect.
