During 2009-2010, we examined 217 cases hospitalized with laboratory-confirmed pandemic influenza in nine FluSurv-NET sites and 413 age- and community-matched controls and found a single dose of monovalent non-adjuvanted influenza A(H1N1)pdm09 vaccine was 50% (95% CI=13%–71%) effective in preventing hospitalization associated with A(H1N1)pdm09 virus infection.
