What is Influenza ( FLU )?

Influenza is an acute infectious disease caused by the virus family of Orthomyxoviridae. Outbreaks of influenza happens and the disease is spread via the respiratory droplets. Patients may manifest symptoms such as malaise, acute febrile illness, runny nose, coughing, headache, muscle aches and sore throat; severe cases may lead to respiratory failure or even death.


Why do I need to receive flu vaccine every year?

The best way to help protect yourself and others from flu is to have the flu jab every year. Over time, protection from the flu jab gradually decreases and flu strains can change, which means last year's jab may not protect you from this year's strains. There may also be an increase in flu cases this autumn due to the lack of exposure to the flu virus last winter driven by reduced social interaction.


At your appointment, one of our pharmacists will inject the vaccine into your upper arm. As with all medicines, there may be some side effects. The most common side effects include:

  • Redness, soreness or bruising at the injection site
  • A high temperature, sweating, shivering or feeling unwell
  • Headaches, fatigue or dizziness
  • Aching muscles or joints


These side effects are usually mild and should disappear on their own in a day or two.

There are very few people who can’t have a flu jab, but it might not be suitable if you’ve had a previous reaction to it. Ask your pharmacist if you’re unsure.
