Authors' objectives:

To evaluate the immunogenicity of a two-dose schedule of Baxter cell-cultured, non-adjuvanted, WV H1N1 vaccine, and GlaxoSmithKline AS03A-adjuvanted, split-virion H1N1 vaccine, with respect to the EU Committee for Human Medicinal Products for Human Use (CHMP) and the US Food and Drug Administration (FDA) licensing criteria.

Authors' recommendations: The AS03A-adjuvanted split-virion 2009 H1N1 vaccine is more immunogenic and provides greater antigen-sparing capacity than the WV 2009 H1N1 vaccine. The adjuvanted vaccine satisfies more CHMP criteria than the WV vaccine. Seroprotection is attained more rapidly with adjuvanted split-virion vaccine than WV vaccine. A second dose of adjuvanted split-virion vaccine increases seroprotection rates more than WV vaccine. The WV vaccine is associated with fewer local and systemic reactions than the adjuvanted vaccine, but, as judged by our findings, the adjuvanted split-virion vaccine is better overall. A single-dose strategy provides potentially greater public health benefits than delivery of two doses to one-half of the population, but a two-dose strategy should be considered for the elderly.
