The takeaway

Did you know flu shots can take two weeks after being administered to take effect? With flu season starting in September, getting your flu shot soon can help you stay healthy. Plus, since it’s possible to get both flu and COVID-19 at the same time, a flu shot can help you avoid the risk of serious complications. Here’s how U.S.-based employees can get a flu shot, depending on their medical provider.

Blue Shield

Blue Shield plan members can visit a pharmacy in the network and get a flu shot at no extra charge. Or, you can get your flu shot at your doctor’s office, if you prefer.

Participating major chain pharmacies (all locations, nationwide) include: Albertsons, Costco, CVS and CVS Pharmacy at Target, Kmart, Kroger, Raley’s, Ralphs, Rite-Aid, Safeway, Vons, Walgreens, and Walmart. 

Check with your pharmacy about their procedures, but most pharmacies administer flu shots with no appointment necessary. Here are details from Blue Shield.
