A multicentre, randomized, phase III clinical trial in 5071 healthy adults was conducted to evaluate the safety and reactogenicity of a 15 microg HA dose of a candidate oil-in-water emulsion-based adjuvant system (AS)-adjuvanted split-virion H5N1 (AS-H5N1) vaccine compared to a licensed seasonal influenza vaccine, Fluarix.(1) Stringent criteria were used to evaluate adverse events and reactogenicity profile. Overall, 96.7% of the 5071 vaccinated subjects completed the study. Significantly more participants in the AS-H5N1 vaccine group reported general or local adverse events. Pain was the most common symptom in both treatment groups. Less than 1% of subjects withdrew from the study due to adverse events and no withdrawals were due to serious adverse events related to vaccination. The safety and reactogenicity profile of the AS-H5N1 candidate vaccine can be considered clinically acceptable in the context of its use against pandemic influenza.
