PREVALENCE OF FLU VACCINATION IN BRAZIL‘S PUBLIC SYSTEM AMONG THE YEAR 2010 TO 2014

Introduction and Objectives: Flu is a common disease, mainly caused by the influenza virus, capable of outbreaks. Vaccination is cost-effective strategy to prevent aggravation. This study aims to evaluate the prevalence of influenza vaccination in Brazil between the years 2010-2014. Methodology: This is a quantitative study with cross section approach held in Brazil between the years 2010-2014. We used a study population composed of the anti influenza vaccine doses made by SUS in Brazil. Data were obtained from the DATASUS system, of secondary order, in the database category in the National Immunization Program (NIP). Results and conclusions: It was found that between 2010 and 2014 were applied 62,276,863 doses of influenza vaccine, with an average of 12,455,372.6 per year. Their geographical distribution is heterogeneous, and Southeast 45.6% and the North with 6% of the applied dose. Immunization against influenza is divided into categories: during vaccination campaigns, out of vaccination campaigns and in pregnant women. Out of vaccination campaigns accounted for 24% of cases during campaigns contains 72.7% of the doses, and immunization of pregnant women 3.3%. It was found that some regions are more protected by the immunization against influenza and vaccine application occurs most frequently during vaccination campaigns. However, more research in this area should be undertaken to assess the effectiveness of vaccination in preventing disease as well as its side effects.
