The frequency of cases of severe side effects detected in the administration of H1N1 vaccines in Japan has been higher than for seasonal flu vaccines said the Japanese Health Ministry.
68 cases of serious side effects were recorded according to a health ministry survey. Eight more deaths were reported outside the survey, bringing the death toll after vaccination to 21.
Although the victims died following vaccination, the committee argued that the vaccines were not necessarily the cause of death. The experts found that in most cases, it was highly likely that they died because the condition of their diseases worsened, they said.
