Couldn't stop me from getting it. Ever since my daughter was diagnosed with diabetes at age 5 (she's now 17), she and everyone else in our family has received a flu shot every year. Doctor's orders. If she were to get the flu, it could be deadly. She and many others have been hospitalized in intensive care during flu season before. Many have died.
People seem to forget that getting a flu shot isn't only for their own protection, but also for those around them who are at high risk of DYING from complications of the flu.
Persons at high risk of dying of complications of the flu are young babies and young children (even normally healthy ones), pregnant women, the elderly, and those who have comprimised immune systems caused by any variety of reasons, those who have heart problems, diabetes, or other chronic conditions, people who have been hospitalized during the previous year. Anyone who is in close contact with any of these people should be vaccinated against the flu. Think of those you care about - Parents, grandparents, children, friends...
You can't get the flu from the flu shot. It contains killed virus:
What are the risks from getting a flu shot?
The viruses in the flu shot are killed (inactivated), so you cannot get the flu from a flu shot. The risk of a flu shot causing serious harm, or death, is extremely small. However, a vaccine, like any medicine, may rarely cause serious problems, such as severe allergic reactions. Almost all people who get influenza vaccine have no serious problems from it.

The nasal spray flu vaccine is a bit different but isn't appropriate for everyone:
