Unintended effects similar to injection website ache, fatigue, complications and muscle aches have been extra widespread with the Moderna shot in comparison with the usual flu shot, however most have been delicate to reasonable and short-lived.
Critical negative effects have been balanced between the 2 teams, occurring in 2.2% of those that acquired the mRNA vaccine and 1.9% of those that acquired the usual dose of the vaccine, the researchers reported.
