Flu vaccination helps protect against seasonal influenza, which can spread easily among travellers, particularly on cruises, group tours, and during winter travel to the opposite hemisphere. A pre-travel consultation can advise whether flu vaccination is recommended for your trip.
What Is Flu?
Flu (influenza) is a common viral infection that spreads easily between people, causing fever, cough, sore throat, muscle aches and fatigue. While most people recover within a week or two, flu can lead to more serious complications in older adults, pregnant women, and those with certain long-term health conditions.
Who Should Consider Vaccination?
The flu vaccine is offered free on the NHS each autumn or winter to people at higher risk, including those aged 65 and over, pregnant women, and people with certain long-term health conditions. For travellers not otherwise eligible, vaccination may still be worth considering before cruises, group tours, visits to the southern hemisphere during its winter season (April to September), or travel to crowded events such as the Hajj pilgrimage.
Vaccination Schedule
The flu vaccine is given as a single annual dose, ideally at least two weeks before travel to allow protection to develop. Because flu strains change and protection reduces over time, a new vaccine is needed each year, matched to the strains expected to circulate in that season.
Vaccination Timing for Travel
If you’re eligible for the free NHS flu vaccine, this is usually offered in autumn. Travellers visiting the southern hemisphere during its flu season, or travelling later in the year after the UK season has passed, may wish to discuss additional or earlier vaccination with a travel clinic.
Frequently Asked Questions
Do I need the flu vaccine before I travel?
It depends on your personal risk factors and travel plans; those on cruises, group tours, or travelling to the opposite hemisphere’s flu season may benefit from vaccination even if not otherwise eligible for the free NHS vaccine.
Is the flu vaccine available on the NHS for travel?
The free NHS flu vaccine is only available to specific eligible groups; travellers outside these groups can access flu vaccination privately through a travel clinic or pharmacy.
How long does flu vaccine protection last?
Protection reduces over time and flu strains change each year, so a new vaccine is recommended annually.
Can the flu vaccine be given with other travel vaccines?
Yes, the flu vaccine can usually be given alongside other travel vaccines at the same appointment.
Can the flu vaccine give me flu?
No, injected flu vaccines used in the UK do not contain live flu viruses and cannot give you flu.
