To protect yourself and others, the CDC recommends that people get a flu vaccine by the end of October, if possible. It takes about two weeks after vaccination for antibodies to develop in the body that will protect against influenza. However, getting vaccinated later can still be beneficial even into January or later.
The agency will not be offering an on-site flu shot clinic this year. However, you can receive a flu shot at your physician’s office as well as walk-in flu shot clinics at urgent cares and many local retailers.
