One person is believed to have died from a serious reaction to the vaccine, Butler-Jones said, but the death hasn't yet been conclusively linked to the flu shot. He said it's possible the elderly person who died suffered from an underlying condition.' l# o5 h0 u" w2 m3 w: J- m
( o2 o. ~# G2 ~0 |/ M% E* dAll the serious side effects came after shots of the adjuvanted vaccine, which contains a compound to boost the vaccine's potency. Butler-Jones said that's likely because the vast majority of people being vaccinated are getting the adjuvanted vaccine.
