“…The other ten studies analyzed vaccine coverage among the senior population. The majority of them were surveys conducted in representative samples of the target population, 7,9,13,16,17,20,24 and the remaining three among outpatients of a primary care clinic and reference hospitals 22,23,30 . Five surveys detected vaccine coverage similar to the Ministry of Health's (MOH) administrative data 9,13,16,17,30 .…”

Five surveys detected vaccine coverage similar to the Ministry of Health's (MOH) administrative data 9,13,16,17,30 . On the other hand, large differences were observed by the other three: among the elderly of two low income communities ("favelas") in the city of Rio de Janeiro, survey coverage was 50.2% and 38.3%, compared to MOH 75.7% coverage for the whole city; 66.3% coverage in Belo Horizonte, the country's third largest city, compared to 85.5% according to MOH data; and 83.8% among outpatients of a primary care clinic in Botucatu, state of São Paulo, compared to 62.2% (MOH) 7,22,24 .…”

SUMMARYSince 1999, Brazil has undertaken annual influenza vaccine campaigns, free of charge, targeting the elderly population, health professionals, and immune-deficient patients. We conducted a systematic review of literature in order to evaluate the effectiveness of the initiative. We used the keywords influenza, vaccine, Brazil and effectiveness to search the main databases. Thirty-one studies matched our inclusion and exclusion criteria. Influenza vaccine coverage among the elderly is high, though not as high as suggested by the official figures. Estimates on effectiveness are scarce. The majority come from ecological studies that show a modest reduction in mortality and hospital admissions due to influenza-related causes. Such reduction is not evident in the North and Northeastern states of Brazil, a finding that is probably related to the different seasonal pattern of influenza in equatorial and tropical regions. Brazilian epidemiologists still owe society better-designed studies addressing the effectiveness of influenza vaccine campaigns.

“…This lack of vaccine uptake has been studied by various Brazilian authors, who have identified the following factors: age 14,15,16 , schooling 15,16 , and comorbidities 14,15,16 . Non-compliance was explained by some myths related to post-vaccination adverse events and even lack of belief in the vaccine 17 .…”

Vaccination is the most effective measure to prevent the complications of influenza. This population-based study aimed to estimate influenza vaccine coverage in non-institutionalized elderly, analyze the factors involved in lack of influenza vaccine uptake, and identify post-vaccination adverse effects. The study population lived in an urban neighborhood in Southern Brazil, and the sample consisted of 425 elderly. A total of 396 elderly individuals (age 60-95 years) were interviewed. Although 100% of the sample reported knowing about the vaccine, only 5.3% referred to their personal doctor as the source of information. Among elders that had not received the vaccine, 83.2% were explicit about not wanting to take it. The main reasons were fear of adverse effects and disbelief in the vaccine's effectiveness. However, the actual prevalence of adverse effects was low. Age, smoking, and lack of a doctor's appointment in the previous year were independently associated with vaccine non-compliance. The results show that improvements are needed in the immunization campaign, especially targeting elders less than 70 years of age and smokers.

“…However, females prevailed among the vaccinated, a distinct result was found for the Spanish population, in which males were 38% more likely to receive the vaccine against pandemic influenza (16) . Investigations carried out with elderly in two municipalities did not observe statistical association between gender and adherence to the seasonal influenza vaccine (17)(18) . Gender is a characteristic that also appears to be unrelated to the severity of infection and the risk of mortality by the pandemic A (H1N1) (19) .…”

RESUmoObjetivou-se investigar os fatores sociodemográficos, clínicos, comportamentais e o recebimento de informações sobre a vacina contra a Influenza pandêmica A (H1N1) associados à vacinação de idosos. RESUmENEl objetivo fue investigar los factores sociodemográficos, clínicos, de comportamiento y el proceso de recepción de información, asociados a la vacunación contra la influenza pandémica A(H1N1) en adultos mayores. Corresponde a un estudio cuantitativo y transversal en el cual participaron 286 adultos mayores residentes en Fortaleza, CE, Brasil. La asociación entre variables se analizó mediante la prueba de chicuadrado de Pearson, considerándose un nivel de significación de 95% (p ≤ 0,05). Los resultados señalaron que, a diferencia de las características sociodemográficas, muchos aspectos clínicos, de comportamiento y relacionados con la entrega de información presentaron una correlación estadísti-camente significativa con la adhesión a la vacuna contra la influenza A (H1N1). Estos resultados podrán ser utilizados en estrategias de control y prevención de la infección por el subtipo viral en la población estudiada, incluso, en otras enfermedades inmunoprevenibles y sobre todo en posibles pandemias futuras.

Abstract: The results suggest the need for campaigns to make information on the benefits of influenza vaccination more easily accessible to the elderly and health professionals.
