What should you know about gsk influenza vaccine?

Influenza vaccination prepares immune defences to respond more quickly if you encounter a virus included in that season's vaccine. An inactivated vaccine contains virus material that cannot cause influenza. Protection develops after vaccination and can vary with age, health, and how closely the vaccine matches circulating viruses. Vaccination lowers the chance of serious illness but does not prevent every respiratory infection.

Tell the vaccinator about previous vaccine reactions, a severe allergy, pregnancy, immune problems, or a current illness. Ask which formulation is appropriate and whether you need a later dose. Wear clothing that allows easy access to the upper arm, drink normally, and remain briefly at the clinic if advised. Mild soreness, tiredness, or a low fever can occur after the injection and usually settles without specific treatment.

Seek urgent help for breathing difficulty, swelling of the face or throat, widespread hives, collapse, or sudden severe dizziness after vaccination. Contact a clinician if fever is persistent, symptoms are worsening, or you are unsure whether a reaction is expected. A vaccine injection does not treat influenza that has already started; new severe breathing symptoms, chest pain, confusion, or dehydration need prompt assessment.

Ask whether this vaccine suits your age and medical history, when protection should be expected, and what to do if you feel unwell on the day. You can also ask about the [Inactivated Vaccine](/materials/inactivated-vaccine/) formulation and whether another vaccine or timing is more suitable.
