Hi @bettya465965, I have not seen services that provide flu vaccines at home. This year, flu shots will be available at pharmacies (like CVS and Walgreens), doctors' offices, and health departments. I believe some health clinics will be providing drive-up flu shot clinics as well.
Typically, the flu vaccine is free with insurance. If you have insurance, I would call them to see if there are at-home services available in your area and if there are, they can tell you the approximate costs.
