The injected flu vaccine is offered free of charge on the NHS to anyone with a serious long-term health condition, including:
This list of conditions is not definitive. It's always an issue of clinical judgement.
A GP can assess you to take into account the risk of flu making any underlying illness you may have worse, as well as your risk of serious illness from flu itself.

Speak to a GP or pharmacist about this.
