The American Academy of Pediatrics recommends flu shots for children of all ages, citing higher effectiveness of the shot versus nasal spray. But for children who refuse needles, FluMist nasal spray is available.
Additionally, some evidence suggests Flucelvax and FluBlok, the only two egg-free vaccines on the market, may work better than the older vaccines grown in eggs. Dr. Richard Zimmerman, who advises the University of Pittsburgh Medical Center's Influenza Committee, said the major hospital group will only be buying egg-free formulations this year.
"The egg-free vaccines appear to have perhaps a 10 percent higher effectiveness over the traditional egg-based vaccines,” Zimmerman said in an interview with NBC News.
Centers for Disease Control and Prevention recommend everyone over the age of six months get a flu vaccine but they "do not recommend one flu vaccine over another."
