    Abstract

    The risk of bronchospasm should still be considered as greatly limiting the use of live attenuated influenza vaccine (LAIV) in children with asthma or history of recurrent wheezing because in some cases a child could have severe asthma at onset that becomes mild with asthma prophylaxis or conversely could have recurrent wheezing in the first years of life before developing later severe asthma. Consequently, the conclusion could be that pediatricians would prefer to avoid any risk and use another influenza vaccine in children with asthma or recurrent wheezing, especially if they consider that immunogenicity and efficacy of influenza vaccination is better in children > 2 years (when LAIV can be administered) in comparison with the younger ones. An interesting information should be to know data on respiratory. Further comprehensive multicenter studies in children and adults with asthma or a history of recurrent wheezing should be useful to clarify safety data of LAIV in these populations.
