The flu jab is offered every year to people at higher risk of getting seriously ill from flu – but there are some cases in which you shouldn’t get vaccinated.
The NHS has advised postponing a crucial autumn vaccination if you display one particular symptom. The health service states you should “wait until you’re feeling better” before getting the flu jab.
The flu vaccination is provided on the NHS annually during autumn or early winter for people at heightened risk of severe flu complications. Those eligible include people aged over 65 and those with specific long-term medical conditions.
The NHS website states that the vaccination is designed to shield you from the “most common types” of flu strains. Nevertheless, there remains a possibility of contracting flu following vaccination, though symptoms are likely to be less severe and shorter in duration.
This year’s autumn/winter vaccination programme has commenced, with appointments available through GP practices, the NHS app, and selected pharmacies. However, there are certain circumstances in which you shouldn’t get vaccinated.
The NHS stated: “If you have a high temperature, wait until you’re feeling better before having your flu vaccine.” Additionally, some people may experience allergic reactions to the injection.
“Most people who are eligible for the flu vaccine can have it,” the NHS confirmed. However, it added: “You only cannot have the vaccine if you’ve had a serious allergic reaction (anaphylaxis) to a previous dose of the vaccine or an ingredient in the vaccine.
“Some of the flu vaccines used in the UK contain egg protein. Tell the person vaccinating you if you have an egg allergy.”
Side effects of the vaccine
The most common side effects of the flu vaccine are “mild” and improve within one to two days. The NHS says they can include:.
- Pain or soreness where the injection was given
- A slightly raised temperature
- An aching body
The NHS added: “The injected flu vaccines used in the UK do not contain live flu viruses. They cannot give you flu.”
Having it with other vaccines
You can receive the flu vaccine at the same time as other vaccines such as the COVID-19 and shingles vaccines. It’s not usually administered at the same time as the RSV vaccine, but you can have them simultaneously if a doctor or nurse thinks it’s necessary.
Who can have the vaccine
You can receive the free NHS flu vaccine if you:
- Are aged 65 or over (including those who will be 65 by March 31, 2026)
- Have certain long-term health conditions
- Are pregnant
- Live in a care home
- Are the main carer for an older or disabled person, or receive a carer’s allowance
- Live with someone who has a weakened immune system
Frontline health and social care workers can also receive a flu vaccine through their employer. For more information, visit the NHS website here.
