Flu shots mandatory where available Published Feb. 3, 2005 WASHINGTON (AFPN) -- Flu shots are mandatory for all active-duty, Reserve and Guard Airmen, where the supply is available, Air Force medical officials said.Because of low supplies, flu shots were previously limited to deployed Airmen, those preparing for deployment and others identified as "at risk." As supplies have increased, those limitations have been lifted, officials said.Airmen should check with their local medical treatment facility for vaccine availability. Despite the lifting of restrictions, not all facilities have an adequate supply of the vaccine. Where available and possible, the flu-mist nasal spray vaccine will be given to those younger than 50 which will take the place of the traditional shot, officials said.
