Most measles cases are in unvaccinated or unknown-status people, not evidence of MMR waning. COVID vaccines protect children, studies confirm.
Japan’s vaccine delay didn’t cause SIDS to drop. Rates rose until 1998, when a safe-sleep program launched. Vaccinated kids have lower SIDS risk.
Many vaccines have been tested with saline placebos, contrary to Del Bigtree’s claim. Active controls are also valid when a safe vaccine exists.
Measles is far deadlier than the MMR vaccine. Paul Thomas’s claim compares mismatched numbers; pre-vaccine measles killed about 1 in 6,000 cases.
In a new video, Dr. Sherri Tenpenny claims that before the vaccine, measles deaths were very rare and that the vaccine isn’t needed.
A recent research paper from Peter McCollough’s group says that 299 deaths in the U.S. were reported after MMR vaccines, mostly in very young children, soon after getting the shot.
In her confirmation hearing, Casey Means avoided clearly backing certain vaccines, saying parents should decide with their doctors. She also claimed we don’t fully know what causes autism and that questions about vaccines and autism should not be completely closed.
In an old video, RFK Jr. claims that none of the 72 required childhood vaccines were properly safety tested, that drug companies push unnecessary vaccines to make money, and that vaccines caused a big rise in autism and other chronic diseases…
