But surveillance activities in Asia and elsewhere have not detected any unusual virus variants this year. It is never too late. The vaccine manufacturers are generally shipping the vaccine first to the people and organizations that ordered it first. Influenza vaccine generally doesn't become available in the U.S. until September. People at increased risk of complications should receive it as soon as it becomes available.
Healthy people can receive it anytime.
The vaccine should be effective for 6-12 months. Healthy people who don't want to get the flu may receive it as well. If you want to reduce your chance of getting the flu this year, get the vaccine. I do not want to bring more germs into our house and have my father be more suspectible to infections. We recommend annual vaccination for children with asthma, and family members of the child.
