As the crisp autumn air settles in, flu season returns, bringing the familiar symptoms of fever, and cough. Each year, influenza , commonly known as the flu, impacts millions of people. For most, it causes a mild to moderate illness, but for some, it can be serious, potentially leading to hospitalization or even death. Even though the onset of flu season may feel routine, it is crucial to remember that the virus evolves annually, making yearly vaccination an essential measure for staying healthy. That said, the NHS has advised delaying your autumn vaccination if you experience one specific symptom. The health service advises that you should “wait until you’re feeling better” before getting the flu jab.NHS Flu VaccinationThe flu shot is offered on the NHS every year during autumn or early winter for individuals at higher risk of severe flu complications. Those eligible include people aged 65 and over, as well as those with certain long-term medical conditions. According to the NHS website, the vaccine protects against the “most common types” of flu strains each year. While it’s still possible to catch the flu after vaccination, symptoms are generally milder and shorter in duration.One Symptom That Means You Should Postpone Your Flu JabThis year’s autumn and winter vaccination program is underway, with appointments available through GP practices, the NHS app, and select pharmacies. However, there are circumstances in which vaccination should be delayed. The NHS recommends: “If you have a high temperature, wait until you’re feeling better before having your flu vaccine.”Some individuals may also be at risk of allergic reactions to the injection. “Most people eligible for the flu vaccine can receive it,” the NHS confirmed, adding: “You should not get the vaccine only if you’ve had a severe allergic reaction (anaphylaxis) to a previous dose or to an ingredient in the vaccine.” Some flu vaccines in the UK contain egg protein, so anyone with an egg allergy should inform the healthcare professional administering the shot.Side Effects Of The Flu VaccineThe NHS notes that side effects are typically mild and usually resolve within one to two days. These can include:Pain or soreness at the injection siteA slightly raised temperatureAching muscles or bodyThe NHS clarifies: “The injected flu vaccines used in the UK do not contain live viruses. They cannot give you flu.”Flu shots can generally be given alongside other vaccines, such as COVID-19 or shingles vaccines. They are not usually administered with the RSV vaccine, though simultaneous vaccination may be advised if a doctor or nurse deems it appropriate.Eligibility For Flu VaccineFlu vaccines are recommended for everyone aged six months and older, with a focus on high-risk groups such as children under five, adults 65 and older, pregnant women, and those with chronic health conditions. Individuals who have previously had a severe allergic reaction to a flu vaccine should consult a healthcare provider before receiving the shot.Recent updates to vaccine policies, particularly around COVID-19 vaccines, have caused some confusion. Many wonder if getting the flu jab has become more complicated. The good news is that flu vaccines remain widely accessible. Pharmacies, GP offices, public health clinics, and many workplaces continue to offer the seasonal injection, often at little or no cost.
