by Ferreira Ramalheira, Raquel Maria

Abstract (Summary)
Respiratory infection, particularly influenza outbreaks are common in institutionalized individuals. Vaccination is the most efficient prevent measure. The aim of this work were: to study respiratory infection incidence in institutionalized elderly subjects in 15 months period and to analyze the occurrence of adverse effects after influenza vaccination in a nursing home in Campinas, São Paulo State. SUS dependent elderly people (N= 154) living in Lar dos Velhinhos de Campinas were visited weekly to detect flu like syndrome from June 2004 to August 2005. It was included individuals with ability to understand and to answer research questions and those who accept to participated. After influenza vaccination campaign of April 2004 (coverage 95%) individuals were investigated in the 5-day to discover vaccine side events. A multiple logistic models were applied to investigate association between co variables and flu like syndrome and adverse events (dependent variables). Among the 154 subjects, it was identified 50 (32.5%) individuals witch present flu like symptoms during study period. Temporal trend of the 76 episodes showed concentration in June 2004 and 2005. Incidence of at least one side effect was 14.3 per 100 vaccinated residents. Local symptoms were referred by 12 (57.1%) individuals, whereas the most frequent complain was local pain in women (53.3%) and men (50%). Neither side effects nor flu like syndrome were associated with co variables in the logistic models. Despite high influenza coverage levels it was detected respiratory virus circulation in the nursing home. It is reinforced the importance of influenza vaccination of residents and staff, and also improvement of routine measures to prevent secretion transmission disease. The safety and low reatogenity of influenza vaccine may help campaign adhesion. Etiologic surveillance of flu like syndrome could improve understanding of the pathogens circulation among risk population
