NCT01066169

Brief Summary

As recommended by the Dutch Health Council, certain risk groups and health care workers in The Netherlands were vaccinated to prevent morbidity due to pandemic influenza A/H1N1. Adults were vaccinated twice with the monovalent influenza A/California/2009(H1N1) MF59-adjuvanted surface-antigen vaccine Focetria® (Novartis). The vaccination campaign was executed by general practitioners. The aim of the study is to verify whether HIV-infected individuals generate an adequate immune response after the first and after the second vaccination.

Interventions

This is not an interventional study. In this observational study we monitored the immune response in a cohort of people who were vaccinated during the national vaccination campaign. The vaccine that was used in The Netherlands is the monovalent influenza A/California/2009(H1N1) MF59-adjuvanted surface-antigen vaccine. It contains 7,5 µg hemagglutinine and the MF59C.1 adjuvant, which is an oil-in-water emulsion, composed of Squalene 9.75 mg, Polysorbate 80 1.175 mg and Sorbitan trioleate 1.175 mg. This vaccine has been approved for use according to a two dose schedule.
