Getting the flu is never fun, but for small children it can be downright dangerous. That's why the FDA lowered its age recommendation for FluMist, the nasal-spray flu vaccine, from 5 years and older to ages 2 and up. Even as more kids get in line to be inoculated, there should be plenty of vaccines for everyone. After recent alarms over shortages, the agency expects 132 million doses of influenza vaccine to be available this winter, up 10 million from last year. The increase is in large part due to the latest addition to the immunization arsenal: Afluria was approved in September by the FDA for adults 18 and over.
