Dear Sir,

The influenza A (H1N1) 2009 pandemic infection in asthmatic patients is very interesting. The attempt to control of H1N1 pdm09 virus infection among the asthmatic patients is a challenging topic. [1] Koshio et al. noted “the effectiveness of the vaccination against the H1N1 pdm09 virus was confirmed during the first pandemic season, but it was limited.” [1] Indeed, the influenza vaccine is generally recommended for the asthmatic patients. An important fact is asthma is a common “comorbid condition in patients infected with this virus.” [2] Hence, the control of influenza might be usefulness in asthma control. However, there are many facts to be discussed. First, whether the vaccine is actually effective in decreasing the problem of asthma is still questionable. Asthma might be less frequent in some seasons and this might be misinterpreted as a result of vaccination. Second, although it is usually mild, the “postinoculation respiratory illness” is a common problem after influenza vaccination in asthmatic patients. [3] Nevertheless, it is no doubt that vaccine is useful for prevention of influenza among the patients with asthma. [4] Finally, it should also be noted that the problem of vaccine coverage among asthma patients still exists and is a problem for further management. [5],[6]
