Safety of MF59-adjuvanted versus non-adjuvanted influenza vaccines in children and adolescents: an integrated analysis.

We reviewed the safety of MF59-adjuvanted versus non-adjuvanted influenza vaccines in children and adolescents (aged 6 months-18 years) in an integrated analysis of all pediatric trials evaluating MF59-containing influenza vaccines completed to date (5 trials). In the MF59-adjuvanted group (n=1181) versus the non-adjuvanted group (n=545) there was no increase in the incidence of unsolicited adverse events and serious adverse events. As expected, solicited local or systemic reactions occurred more frequently in MF59-adjuvanted subjects; however, a majority of reactions were mild and transient. These data support the safety of MF59-adjuvanted influenza vaccines in the pediatric population.
