Messenger RNA technology, which had never been widely used before Covid-19 vaccines, has been the target of many conspiracy theories, despite being shown to be highly safe. A rare risk of myocarditis (inflammation of the heart muscle) has been identified following Pfizer or Moderna injections, especially in young male adolescents, but the vast majority of cases are not severe, with short hospital stays. The FDA said it will continue to closely monitor data on all vaccines. †Our action reflects the robustness of our surveillance system and our commitment to ensuring we follow science and data in our decisions.‘ said Peter Marks.
