Introduction: The frequency and mortality of the pandemic caused by influenza A(H1N1)pdm09 might have been underestimated, especially in developing countries. This study was designed to quantify the possible underestimation of pandemic influenza mortality and evaluate the concordance between the data reported for A(H1N1)pdm09 mortality and the causes of death reported during the pandemic period of April 2009 to February 2010.
Methodology: The death certificates of 754 confirmed cases of A(H1N1)pdm09 infection were included in the study.
Objective: to evaluate the coverage and impacts of the vaccination component in Integrated Health Programs.
Material And Methods: a descriptive study of secondary data analysis was carried out. We analyzed data generated by the Universal Vaccination Program (PROVAC) since 1991, the data compiled in the 2000 National Health Survey (ENSA) and the 2005 National Survey of Coverage of Integrated Health Programs (ENCOPREVENIMSS), as well as the IMSS Annual Epidemiological Gazettes since 1973.
