Is flu vaccination safe in older adults?

Influenza can place extra strain on the lungs, heart and other body systems, particularly when an older person has long-term conditions. Vaccination prepares an immune response before exposure. It cannot prevent every respiratory infection, and protection can vary between seasons, but it is part of a broader plan that may include hand hygiene, ventilation and avoiding close contact with someone who is ill. The vaccine cannot cause flu through a multiplying virus.

Bring a list of regular medicines and tell the vaccinator about severe allergies, a previous reaction to a vaccine, immune-suppressing treatment, bleeding problems, or a current fever. Ask which formulation is recommended locally for your age and conditions. After vaccination, move the arm gently and drink normally. A sore arm, fatigue or a mild fever may occur for a short time.

Call emergency services for breathing difficulty, throat or facial swelling, widespread hives, collapse, or severe sudden weakness after vaccination. Contact your clinician if symptoms are worsening, fever persists, or you are confused, unusually drowsy, or unable to drink. New breathlessness or chest pain should be assessed urgently whether or not it follows vaccination.

Ask which product fits your age and medical conditions, whether any medicine needs special consideration, how to distinguish expected effects from illness, and when seasonal vaccination should be arranged.
