During the 2009/10 influenza A(H1N1)pdm09 pandemic, the five Nordic countries adopted different approaches to pandemic vaccination. We compared pandemic vaccination strategies and severe influenza outcomes, in seasons 2009/10 and 2010/11 in these countries with similar influenza surveillance systems. We calculated the cumulative pandemic vaccination coverage in 2009/10 and cumulative incidence rates of laboratory confirmed A(H1N1)pdm09 infections, intensive care unit (ICU) admissions and deaths in 2009/10 and 2010/11. ⋯ Compared with Denmark, the other countries had higher pandemic vaccination coverage and experienced less A(H1N1)pdm09-related severe outcomes in 2010/11. Pandemic vaccination may have had an impact on severe influenza outcomes in the post-pandemic season. Surveillance of severe outcomes may be used to compare the impact of influenza between seasons and support different vaccination strategies.

Vaccination Against Seasonal or Pandemic Influenza in Emergency Medical Services.
Influenza is a major concern for Emergency Medical Services (EMS); EMS workers' (EMS-Ws) vaccination rates remain low despite promotion. Determinants of vaccination for seasonal influenza (SI) or pandemic influenza (PI) are unknown in this setting. ⋯ Average vaccination rate in this study's EMS-Ws was below recommended values, particularly for women. Previous vaccination status was a significant determinant of PI and future vaccinations. The new mask policy seemed to play a dual role, and its net impact is probably limited. This population could be divided in three groups: favorable to all vaccinations; against all, even in a pandemic context; and ambivalent with a "pandemic effect." These results suggest a consistent vaccination pattern, only altered by exceptional circumstances.
