Summary of influenza immunisation policy
Public Health England
Influenza is characterised by the sudden onset of fever, chills, headache, myalgia and extreme fatigue. Other common symptoms include a dry cough, sore throat and stuffy nose. For otherwise healthy individuals, influenza is an unpleasant but usually self-limiting disease with recovery usually within two to seven days. The aim of influenza immunisation is to reduce the morbidity and mortality from influenza by immunising those most likely to develop severe or complicated illness as a result of influenza infection.
This Guidelines summary covers at-risk groups recommended for influenza immunisation, and administration.
