evidence: Kirsch made many allegations in his presentation about the dangers of COVID-19 vaccines. Regarding the Pfizer vaccine, he claimed that a six-month study showed the Pfizer vaccine "killed five people" for each COVID-19 death it prevented. At the hearing, he said the statistic was not statistically significant but was still troubling. [...] COVID-19 has killed nearly 675,000 people in the U.S., and more than 4.5 million worldwide. The vaccines authorized in the U.S. have been shown to significantly reduce the likelihood of severe illness, hospitalization and death from COVID-19. And no evidence has established that a COVID-19 vaccine authorized in the U.S. caused any deaths. The CDC analyzed vaccine effectiveness across 13 jurisdictions from April 4 to July 17 and matched that data to vaccine registries from those areas. It found that after delta became the most dominant variant of the coronavirus, unvaccinated people were five times more likely to be infected than fully vaccinated people, and more than 10 times more likely to be hospitalized or die.
