Not much evidence for efficacy of flu vaccines

Standard

Consider two Cochran Reviews.

The first, regarding “Vaccines for preventing influenza in healthy adults”, concludes

Influenza vaccines have a modest effect in reducing influenza symptoms and working days lost. There is no evidence that they affect complications, such as pneumonia, or transmission.

The second, regarding “Vaccines for preventing influenza in the elderly”, concludes

The available evidence is of poor quality and provides no guidance regarding the safety, efficacy or effectiveness of influenza vaccines for people aged 65 years or older. To resolve the uncertainty, an adequately powered publicly-funded randomised, placebo-controlled trial run over several seasons should be undertaken.
