About the Flu (Influenza) Vaccination
Book AppointmentIt’s best to receive the vaccine between October and November, before flu season begins
Requires one injection per season—no booster needed
Administered via a single injection in the upper arm
Protection lasts for up to one year, with immunity starting around two weeks after vaccination
Common, mild side effects may include, redness, swelling, or soreness at the injection site
You’ve had a severe allergic reaction to a previous influenza vaccine or its ingredients or you currently have a high fever or acute infection—postpone vaccination until recovery
Risk if you contract
Influenza can cause sudden, severe symptoms such as high fever (38–40 °C), headache, muscle and joint aches, fatigue, cough, and sore throat. While most recover in 3–5 days, fatigue may linger, and for vulnerable groups—such as the elderly or those with chronic illnesses—it may result in serious complications and potential hospitalisation.

Do I need the flu vaccine?
The influenza vaccine is recommended for:

Adults aged 65 years and over
-
People with chronic conditions (e.g., heart or lung disease)

-
Pregnant women (from the 2nd trimester onwards)

Even if you’re healthy, vaccination lowers your chances of infection and helps prevent spreading flu to vulnerable groups.
How effective is the flu vaccine?
The vaccine significantly reduces the risk of contracting influenza and lowers the chance of serious complications if you do become infected. Because flu viruses change each year, the vaccine is updated annually to target the strains most likely to circulate.
How long does the flu vaccine last?
Protection develops about two weeks after vaccination and lasts for up to one year. Annual vaccination is required to stay protected against new strains.
When should I get the flu vaccine?
The best time is October to November, just before flu season begins. This ensures you’re fully protected when the risk of infection is highest during winter.
How much does the flu vaccine cost?
A short free consultation with our specialist nurse is required to assess your medical history before administering the vaccine. A dose of the Flu vaccine costs £19, and 1 dose is required.

Frequently Asked Questions
Is the flu vaccine safe during pregnancy?
Yes. It is safe from the second trimester and also helps protect your baby after birth through transferred antibodies.
Can I get flu from the vaccine?
No. The flu vaccine contains inactivated virus fragments that cannot cause flu.
Why do I need the vaccine every year?
Because flu viruses mutate regularly, new vaccines are formulated annually to protect against the most likely circulating strains.
What if I’m ill on the day of my appointment?
If you have a fever or acute infection, your vaccination should be postponed until you recover.
Do antibiotics help with flu?
No. Flu is viral, so antibiotics are not effective. Rest, fluids, and time are the best treatments.
