About the Flu Vaccine
When Should You Get the Flu Vaccine
The flu vaccine (flu jab) is recommended annually, ideally before the winter season begins, as flu cases tend to rise between October and March in the UK. However, it is still beneficial to get vaccinated later in the season if you have not yet had your flu jab.
You should consider booking a flu vaccine in London as early as possible if you:
- Want to reduce your risk of infection during peak flu season
- Work in busy environments or travel frequently
- Are in a higher-risk group, including older adults or those with underlying conditions
Our specialist nurses will assess your medical history and advise on the best timing for your vaccination.
Vaccine Schedule
The flu vaccine is given as a single injection in the upper arm.
Unlike some other vaccines, the flu jab is required once per year, as the vaccine is updated annually to protect against the most common circulating strains in the UK.
Our clinicians will ensure you receive the most appropriate seasonal flu vaccine based on current medical guidance.
Booster Requirements
A booster is not required within the same season. However, annual vaccination is recommended, as immunity decreases over time and flu strains change each year.
Booking your flu jab each year ensures you remain protected against the latest strains.
How the Flu Vaccine Is Given
The flu vaccine is administered as a quick injection during your appointment.
Your visit typically lasts around 10–15 minutes and includes:
- A brief medical consultation
- Assessment of suitability
- Safe administration of the vaccine
Our goal is to provide a fast, convenient flu jab experience, ideal for those looking for a private flu vaccine in London.
How Long Does the Flu Vaccine Last
Protection from the flu vaccine develops within approximately 10–14 days after vaccination.
Immunity gradually reduces over time, which is why a yearly flu vaccine is recommended to maintain protection.
Possible Side Effects
Most people tolerate the flu vaccine well. Flu vaccine side effects are usually mild and short-lived.
Possible side effects include:
- Pain, redness or swelling at the injection site
- Mild fever
- Headache
- Tiredness
- Muscle aches
Who Can Have the Flu Vaccine
The flu vaccine is suitable for most adults and children and is particularly recommended for:
- Adults over 50
- Pregnant women
- Individuals with chronic health conditions
- Healthcare workers and those in public-facing roles
Anyone wanting to reduce their risk of flu
We also provide guidance on children’s flu vaccines and suitability based on age.
Flu Vaccine and Pregnancy
The flu vaccine is safe during pregnancy and recommended at any stage.
It helps protect both the mother and the baby during early life, when infants are more vulnerable to infections.
Our specialist nurses will ensure the vaccine is appropriate and answer any questions you may have.
Risk of Catching Flu
Flu (influenza) is a highly contagious viral infection spread through coughs, sneezes and close contact.
Symptoms can include:
- Sudden fever
- Headache
- Muscle aches
- Fatigue
- Sore throat and cough
While many people recover within a few days, flu can lead to serious complications such as pneumonia, particularly in vulnerable individuals.
Vaccination remains the most effective way to reduce your risk.
