Boikos C, et al. – Researchers in this study tried to ascertain adverse events following live–attenuated intranasal influenza vaccine (LAIV) of children with cystic fibrosis. Based on the results obtained, 0–6 days after LAIV administration, adverse events were most common. However, these adverse events were generally benign and self–limiting. Moreover, pulmonary exacerbations did not increase in frequency.
