[Evaluation of the influenza a H1N1 vaccination in Castilla and Leon regions, Spain]

Background and objectives: The recent approval of influenza A H1N1 monovalent vaccine has attracted considerable public health interest. The aim of this paper is to assess the development of vaccination campaign in Castilla y Leon.
Material and method: We have performed a descriptive analysis of the number of vaccines given in Castilla y Leon from November 16, 2009 to January 17, 2010, inside the designed campaign for that purpose.
Results: The total number of vaccines administered has been 116,243, 86,810 of which were from Focetria(®) which were administered to 3286 children under 18 years; 28,439 were from Pandemrix(®) and 994 from Panenza(®). The estimated vaccination coverage for all of the target groups has reached a percentage of 26.3% while the coverage achieved in pregnant women has been 4.7%. Of all the vaccines administered during this period, 82.2% were applied in the first month of the vaccination campaign.
Conclusion: The introduction of pandemic vaccine in target groups of Castilla y Leon has been lower than expected, with a mismatch between the different health areas.
