Peak time for seasonal flu in the United States generally falls in January or February, but activity can erupt as early as October. The Centers for Disease Control and Prevention recommends that everyone over the age of 6 months get a dose of the influenza vaccine. Under the Affordable Care Act, all marketplace plans must cover the cost -- so long as the provider is in network. Flu shots are also free under Medicare and many other plans.
For families without coverage, flu shots from a doctor's office can be costly. To find the cheapest place to get the vaccine, Cheapism.com checked prices at six of the country's largest pharmacy chains, as well as Costco and Sam's Club, which are known for low prices and allow non-members to use their pharmacies. The survey was conducted in mid-October and prices may vary by location.
