Children’s Health Defense: “VAERS [US] data released today showed 227,805 reports of adverse events following COVID vaccines, including 4,201 deaths and 18,528 serious injuries between Dec. 14, 2020 and May 14, 2021.”
Depending on which study you read, you can multiply reported adverse-effect numbers by 10 or 100, to arrive at a truer estimate of the human damage.
