If you're aged 18 to 64 years old, you can book a free flu vaccine:
have certain long-term health conditions
are pregnant
are in long-stay residential care
receive a carer's allowance, or are the main carer for an older or disabled person who may be at risk if you get sick
live with someone who is more likely to get a severe infection (such as someone who has HIV, has had a transplant, or is having certain treatments for cancer, lupus or rheumatoid arthritis)
are a frontline worker in a social care setting (if you cannot get a flu vaccine through your employer)
