Seasonal flu vaccination in Dutch at-risk populations was not affected by A(H1N1) 2009 pandemic vaccination.

We read with interest the recent paper by Maurer and colleagues describing the attitudes toward seasonal and H1N1 vaccination and vaccination uptake among US adults (Maurer et al., 2010). They found the 2009 influenza A(H1N1) vaccine uptake as considerably lower than seasonal vaccine uptake, which is not consistent with vaccination rates of patients at-risk we found in the Netherlands.(aut. ref.)
