Actual (reported)A cohort of 4000 community-dwelling adults is followed to evaluate the effectiveness of the Finnish national A(H1N1)v influenza vaccination campaign in preventing the first episode of laboratory-confirmed A(H1N1)v influenza. The safety of vaccination and the severity of the disease are followed primarily from health care registers. In a subgroup of 200 participants, the humoral and cellular immunogenicity of the vaccine will be studied.
