CDC: Best time to get your fall flu vaccine
The U.S. Centers for Disease Control and Prevention recommends that most people receive their annual influenza vaccine in September or October, with the agency advising that 'ideally, everyone should be vaccinated by the end of October.' The guidance includes specifics for children (some aged 6 months–8 years need two doses spaced four weeks apart), cautions about earlier vaccination for certain groups, and notes that protection takes about two weeks after vaccination.

Best time to get the flu vaccine this fall as influenza season approaches
New information:
- CDC recommends September–October as the optimal vaccination window and says everyone should be vaccinated by the end of October.
- Children 6 months to 8 years who are getting vaccinated for the first time—or who lack a prior history of two or more doses—may require two doses with at least four weeks between them.
- It takes about two weeks after vaccination for antibodies to develop; flu shots are available for anyone aged 6 months and older.
