Some experts questioned whether Moderna had collected sufficient data on potential side effects. Regulators and scientists are particularly concerned about the risk of heart disease myocarditis, or inflammation of the muscles of the heart, pericarditis, or inflammation of the lining around the heart.
The June FDA attached a warning about these risks to the Pfizer-BioNTech and Moderna vaccines, and Thursday officials said that men aged 18 to 25 years who were fully vaccinated with either Moderna or Pfizer-BioNTech. He said the risk was high.

Dr. Alroy-Preis said some vaccines provide protection for years after booster shots. Whether that applies to the coronavirus vaccine is a “million-dollar issue,” she said.
