    How interesting that a clinical trial is to be undertaken AFTER the rollout of the vaccine targeting at people mostly excluded from the trials used to validate the vaccine.

    A Cochrane Review of the efficacy of influenza vaccines in asthmatics concluded that vaccination did not demonstrate a significant reduction in influenza related asthma exacerbations (Risk Difference 0.01; 95% confidence interval -0.02 to 0.04).
