The toxic effects of mercury have long been known, but vaccines containing dangerous levels of mercury are still administered to children. From Dr. Sircus at drsircus.substack.com:

Save a vaccine terrorist organization? When it comes to injecting Thimerosal (mercury) into children and calling it safe, we might as well say alligators in your backyard and great white sharks swimming where you are are enjoyable experiences. The amount of ethylmercury in a multidose flu shot is 25,000 times the EPA’s safety level for drinking water. Federal and state laws provide that whenever expired thimerosal vaccines are disposed of, they constitute hazardous waste.
Between conception and age 18, a compliant American child today could get a cumulative load of as much as 500 mcg of ethylmercury from multidose flu shots—nearly double what they were once getting from all the childhood vaccines put together.
Kids who received 100 micrograms of Thimerosal were over ten times more
likely to have autism than the kids who received no mercury-containing vaccines.

In 1998, the FDA banned Thimerosal in all over-the-counter products, ending its use in creams, eye medicine, and disinfectants like mercurochrome. It’s ironic that the CDC, still recommends its injection into babies. No one in their right mind can call vaccines safe because the government pays out billions to parents of vaccine-damaged children.
In 2025, the new slate of vaccine advisers to the US Centers for Disease Control and Prevention voted Thursday to recommend that Americans receive influenza vaccines that are free of Thimerosal, even though, according to every media outlet, there is no evidence of harm from the preservative. No wonder the mass media have lost the trust of most people. Now the recommendation is that NO ONE, Not One Baby, pregnant woman, or anyone else, get a flu shot with Thimerosal, and the media and every pro-vaccine expert in the world can shout and cry all they want. Still, at least in America, this nasty neurotoxic poison is finally out of the child vaccine schedule.
