The majority of Americans who have not been vaccinated - or who say they are hesitant about vaccinating their children - report that safety is their main concern. And decades of vaccine history - plus data from more than a billion people who have received COVID vaccines starting last December - provide powerful proof that there is little chance that any new dangers will emerge from COVID vaccines. Vaccines, given in one- or two-shot doses, are very different from medicines that people take every day, potentially for years.

What makes Goepfert think that scientists would not discover previously unsuspected problems caused by COVID vaccines in the years ahead? “A 90 percent decrease in risk of infections, and 94 percent effectiveness against hospitalization for the Pfizer and Moderna vaccines is fantastic,” he said.īut what makes vaccine experts such as Goepfert confident that COVID vaccines are safe in the long term? We have all seen billboards and TV infomercials from law firms seeking people harmed by diet drugs or acid-reflux medicines for class-action lawsuits.

That data is already in, and it is overwhelming. Many Americans say they want to “make sure the shot is safe” before getting vaccinated.
