U.S. public-health leaders sought to reassure Americans that Covid-19 shots are safe and to get vaccinated after reports that a relatively small number of mostly young men had suffered a heart problem after being immunized.
About 1,200 cases of heart inflammation have been reported in people who received messenger RNA Covid-19 vaccines, according to the Centers for Disease Control and Prevention. The numbers were reported at a Wednesday meeting of the CDC’s Advisory Committee on Immunization Practices.
