The FDA on Wednesday said it plans to add a warning to Pfizer and Moderna vaccines after a CDC advisory panel said data suggests a "likely association" between the vaccines and rare cases of heart inflammation in adolescents and young adults. Despite the warning, doctors and researchers say they still strongly recommend that all Americans 12 and older get vaccinated, noting that the heart problems are uncommon and in most cases very mild.
