Can I get an in-home flu shot for my elderly loved one?

hey, a question I can answer. My mom had visiting nurses who come to her house to draw blood. They gave her a flu shot right in her home. I would call your local hospital or senior center. They can give you the number for the visiting nurses

Flu shots are given by doctors, at pharmacies and health departments - none of which make house calls, unfortunately.
Unless you have what is known as a "concierge" doctor who provide health care to his/her patients at home.
