Cases of myocarditis soared among U.S. service members in 2021 after the COVID-19 vaccines were rolled out, a top Pentagon official has confirmed.

There were 275 cases of myocarditis in 2021—a 151 percent spike from the annual average from 2016 to 2020, according to Gilbert Cisneros Jr., undersecretary of defense for personnel and readiness, who confirmed data revealed by a whistleblower earlier this year.
