Influenza is an acute viral infection which affects the respiratory tract and has systemic symptoms.
Most people do not experience any symptoms. Some people may have mild, moderate, or severe symptoms. Onset is sudden, and symptoms include:
In the majority, symptoms last for 3 to 5 days. Patients rapidly recover, although some feel weak and lethargic for several weeks
Some people are more likely to develop complications if they contract influenza. It is important for these “high-risk” patients to receive their flu vaccination annually
The seasonal flu vaccine (flu jab) protects against 4 strains of flu virus. These are the strains most likely to be circulating this flu season.
You need to get a new vaccine every Autumn. This is because the strains of the flu virus change. This is why it is called seasonal flu.
It is recommended that you get your vaccine in Autumn, to give yourself the best protection against the virus over the Winter months.
A flu vaccine can be booked in all our McGreals Pharmacies.
