If vaccines were 100% safe they wouldn’t need liability protection. There wouldn’t be a vaccine court. There would be studies on the metals contained in vaccines and the risk they pose in the blood stream.
I would still vaccinate my kids (its gambling) and still get a tetanus shot, but no way on the flu shot or any other shot. And that hpv vaccine shot they give teenagers not a chance in hades I would ever do that one. That one is way bad.
