title: [Effectiveness of anti-flu vaccine in the elderly].
abstract: OBJECTIVE
  To evaluate the effectiveness of anti-flu vaccination on elderly people not in institutions, by measuring its effect on the reduction of deaths and hospital admissions due to Cardio-respiratory failure.
  
  
  METHODS
  A retrospective cohort.
  
  
  METHODS
  La Chana Health Centre, Granada.
  
  
  METHODS
  1,965 elderly people who were seen at the Health Centre over the previous three years.
  
  
  RESULTS
  779 elderly people (39.6%) were vaccinated. 35 were admitted to hospital with Cardio-respiratory failure and 59 died. Of these two groups, 13 and 23 respectively had been given the anti-flu vaccination that year. After checking for variables which could lead to confusion, the vaccine was shown to be effective both in reducing admissions (advantage ratio 1,330) and deaths (advantage ratio 1,221).
  
  
  CONCLUSIONS
  Given the effectiveness of anti-flu vaccinations, active efforts to encourage non-institutionalised elderly people to be vaccinated should be increased.
