"With any vaccination campaign, we expect to see some cases of serious adverse events," he said. "They are very rare, but they are part of all mass-vaccination campaigns and we expect to see a small number of them."

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.

All 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.6 N0 f! {* v8 K% i7 r
