Anxiety, not problems with shots, caused adverse vaccine reactions

It was anxiety - and not a problem with the shots - that caused fainting, dizziness and other short-term reactions in dozens of people at coronavirus vaccine clinics in five states, U.S. health officials have concluded. Many of the 64 people affected either fainted or reported dizziness. Some got nauseous or vomited, and a few had racing hearts, chest pain or other symptoms. None got seriously ill.
