What should you know about universal influenza vaccine?

Influenza viruses change over time and include different strains. A universal approach seeks immune protection against shared parts of these viruses, potentially reducing the need to update protection as often. This is a development goal rather than a reason to delay an available seasonal vaccination. Vaccine products differ in formulation, including whether they contain live or inactivated material, and none prevents every respiratory illness.

Ask a clinician which influenza vaccine is available and suitable for your age, pregnancy status, allergies and medical history. Tell them about a previous serious reaction to a vaccine or an illness affecting your immune system. After vaccination, a sore arm, tiredness or a mild fever can occur for a short time. Rest, drink fluids and seek advice if symptoms are severe, unusual or continue. Vaccination works alongside hand hygiene, ventilation and staying home when acutely unwell.

Get urgent help for trouble breathing, swelling of the face or throat, collapse, or rapidly spreading hives after vaccination. These may indicate a serious allergic reaction. Seek medical advice for a persistent high fever, severe weakness or symptoms that are worsening rather than settling. A flu vaccine cannot treat an infection already established, so severe flu symptoms need their own assessment.

Which influenza vaccine is appropriate for me, and is an inactivated vaccine suitable? When should I receive it? How should my previous vaccine reactions, pregnancy or immune condition affect the plan?
