Effectiveness of Flu Vaccination and Burden of Illness Among Community-dwelling Elderly With Influenza Like Illness in Brazil

Influenza Clinical Trial

Official title:
An Observational Case Control Study of Effectiveness of Influenza Vaccination and Burden of Illness in Community-dwelling Elderly With Influenza-like Illness in Southern Brazil

Clinical Trial Summary

The purpose of this research study is to estimate how many elderly people who have symptoms that look like influenza (i.e. an influenza-like illness) actually have the disease and how effective influenza vaccines are in preventing influenza in elderly people. The study will also examine the severity of the disease (e.g. how long are people ill, were there any complications) and how it affects everyday life (e.g. cost, medications, care by family members).
