They prevented about 14.4 million deaths worldwide, according to <a class=\"css-yywogo\" href=\"https:\/\/www.thelancet.com\/journals\/laninf\/article\/PIIS1473-3099(22)00320-6\/fulltext\" title rel=\"noopener noreferrer\" target=\"_blank\">one estimate<\/a>.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">In a small percentage of people, they also produced side effects.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">Over the course of more than a year, The New York Times talked to 30 people who said they had been harmed by Covid vaccines. Their symptoms may turn out to be unrelated to the shots. But they \u2014 along with more than a dozen experts \u2014 felt federal officials are not doing enough to investigate their complaints.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">All vaccines carry some risk of side effects. More than 270 million Americans received about 677 million doses of the Covid vaccines, and even rare side effects \u2014 occurring, say, in just 0.001 percent of patients \u2014 might mean thousands of recipients were affected.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">Indeed, more than 13,000 have submitted claims to a government fund that compensates people for Covid vaccine injuries. So far, however, only a dozen people have been compensated, nearly all of them for a heart problem caused by the vaccines.<\/p>\n<\/div>\n<\/div>\n<div><\/div>\n<div class=\"css-s99gbd StoryBodyCompanionColumn\">\n<div class=\"css-53u6y8\">\n<p class=\"css-at9mc1 evys1bk0\">Here are four takeaways from our investigation.<\/p>\n<\/div>\n<\/div>\n<div>\n<div data-testid=\"lazy-loader\"><\/div>\n<\/div>\n<div class=\"css-s99gbd StoryBodyCompanionColumn\">\n<div class=\"css-53u6y8\">\n<h2 class=\"css-9ycfei eoo0vm40\" id=\"link-32213fa\">For most people, the benefits of Covid vaccines outweigh any risks.<\/h2>\n<p class=\"css-at9mc1 evys1bk0\">Even the best vaccines and drugs have some side effects. That does not negate their benefits, nor does it suggest that people should stop taking them.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">The rotavirus vaccine, for example, is an unmitigated success, but it can lead to intussusception \u2014 a life-threatening condition in which the intestine folds in on itself \u2014 in about 0.02 percent of children who are vaccinated.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">Some side effects caused by the Covid vaccines may be equally rare. Researchers in Hong Kong analyzed that country\u2019s health records and found that about seven of every million doses of Pfizer-BioNTech vaccine triggered a <a class=\"css-yywogo\" href=\"https:\/\/www.thelancet.com\/journals\/lanwpc\/article\/PIIS2666-6065(22)00012-8\/fulltext\" title rel=\"noopener noreferrer\" target=\"_blank\">bout of shingles<\/a> serious enough to require hospitalization.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">Other side effects are slightly more common. The Covid vaccines may lead to myocarditis, or inflammation of the heart, in one of every 10,000 adolescent males. (Myocarditis is one of the four serious side effects acknowledged by federal health officials.)<\/p>\n<\/div>\n<\/div>\n<div><\/div>\n<div class=\"css-s99gbd StoryBodyCompanionColumn\">\n<div class=\"css-53u6y8\">\n<p class=\"css-at9mc1 evys1bk0\">Deaths from the vaccines are vanishingly <a class=\"css-yywogo\" href=\"https:\/\/www.nature.com\/articles\/s41467-022-35653-z\" title rel=\"noopener noreferrer\" target=\"_blank\">rare<\/a>, despite <a class=\"css-yywogo\" href=\"https:\/\/www.nbcnews.com\/nightly-news\/video\/nurse-speaks-out-after-being-subject-of-anti-vaccine-conspiracy-theory-169818693905\" title rel=\"noopener noreferrer\" target=\"_blank\">claims<\/a> from some <a class=\"css-yywogo\" href=\"https:\/\/www.washingtonpost.com\/politics\/2023\/01\/03\/damar-hamlin-charlie-kirk-vaccines-coronavirus\/\" title rel=\"noopener noreferrer\" target=\"_blank\">conspiracy theorists<\/a> that vaccines <a class=\"css-yywogo\" href=\"https:\/\/www.rasmussenreports.com\/public_content\/politics\/public_surveys\/died_suddenly_more_than_1_in_4_think_someone_they_know_died_from_covid_19_vaccines\" title rel=\"noopener noreferrer\" target=\"_blank\">have led<\/a> to a <a class=\"css-yywogo\" href=\"https:\/\/www.latimes.com\/business\/story\/2023-04-11\/anti-vaxxers-loved-to-cite-this-study-of-covid-vaccine-deaths-now-its-retracted\" title rel=\"noopener noreferrer\" target=\"_blank\">spike<\/a> in mortality rates. <\/p>\n<p class=\"css-at9mc1 evys1bk0\">More intensive analysis may indicate that in some groups, like young men, the benefit of Covid shots may <a class=\"css-yywogo\" href=\"https:\/\/www.medrxiv.org\/content\/10.1101\/2023.12.07.23298573v1.full.pdf\" title rel=\"noopener noreferrer\" target=\"_blank\">no longer outweigh<\/a> the risks. But for the majority of Americans, the vaccines continue to be far safer than contracting Covid itself.<\/p>\n<h2 class=\"css-9ycfei eoo0vm40\" id=\"link-11393302\">Federal surveillance has found some side effects but may miss others.<\/h2>\n<p class=\"css-at9mc1 evys1bk0\">To detect problems with vaccines, federal agencies rely on multiple databases. The largest, the Vaccine Adverse Event Reporting System, is useful for generating hypotheses, but contains unverified accounts of harms. Other databases combine electronic health records and insurance claims.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">These systems spotted blood-clotting problems associated with the Johnson &amp; Johnson vaccine and a potential risk of stroke after mRNA immunizations, which is still under investigation. But federal researchers trailed Israeli scientists in picking up myocarditis as a problem among young men.<\/p>\n<p class=\"css-at9mc1 evys1bk0\">The American health care system is fragmented, with medical records stored by multiple companies that do not collaborate. Electronic health records do not all describe symptoms the same way, making comparisons difficult.
