When and Where to Get Your Flu Shot in Philadelphia This Season
PHILADELPHIA — Flu season is approaching, and early October sits squarely in the window health experts recommend for getting vaccinated. The Centers for Disease Control and Prevention advises that September and October are generally the best months for most people to get the flu shot, with everyone ideally vaccinated by the end of October.
The CDC recommends annual flu vaccination for everyone six months and older who does not have a medical reason to avoid it, according to the agency’s 2026-27 guidance summarized by medical publications. The vaccine takes about two weeks to take effect, and flu activity typically starts rising in October and peaks between December and February.
Most adults need just one dose for the season, according to the CDC’s guidance. Some children ages 6 months through 8 years need two doses given at least four weeks apart if they have not been vaccinated on schedule before, so families with young children should start early, according to the same guidance.
Adults 65 and older face higher risk from the flu and should ask about enhanced vaccines. The CDC recommends that people 65 and older receive a high-dose, adjuvanted or recombinant flu vaccine instead of a standard-dose shot, according to health publications summarizing the guidance. Johns Hopkins Medicine notes that all 2026-27 vaccines were designed to protect against three influenza viruses, and a newly approved mRNA flu vaccine is available for adults 50 and older.
Getting the shot in September or October rather than earlier matters for some people. Most adults, especially those 65 and older, generally should not get vaccinated in July or August because protection can fade over the course of the season, according to the CDC. But vaccination after October is still worthwhile, and the CDC says it should continue through the season while viruses are circulating.
In Philadelphia, flu shots are widely available at most pharmacies, doctors’ offices and retail clinics, according to health publications. City health centers also offer vaccinations, often at low or no cost for eligible residents. Readers without insurance or a regular doctor should check with the Philadelphia Department of Public Health for local clinic schedules and costs.
People with questions about which vaccine is right for them, including pregnant people, those with egg allergies or people with certain health conditions, should talk with a doctor or pharmacist.
