Do You Need a Flu or COVID Jab Before Travelling in 2026?
This guide covers the current NHS and UKHSA guidance on flu and COVID-19 vaccinations for UK travellers in 2026, who they're most important for, and how to get them sorted before you fly.
Do You Need a Flu Jab Before Travelling?
The flu jab is not a legal entry requirement for any country, but that doesn't mean it isn't worth having before you travel.
Why flu risk increases when you travel:
Airports, long-haul flights, cruise ships and busy tourist destinations put you in close contact with large numbers of people from different parts of the world. Flu strains circulating in your destination country may differ from those in the UK, and in tropical or subtropical regions, flu can circulate year-round rather than following the typical autumn-to-spring pattern. The NHS advises travellers heading to the southern hemisphere between April and September to get vaccinated before departure, as this coincides with peak flu season in those regions.
It is worth noting that the 2025/26 flu season has been exceptionally severe, driven by a dominant and highly infectious H3N2 subclade, making vaccination particularly important heading into any travel period.
Who the NHS recommends the flu vaccine for:
Adults aged 65 and over
Pregnant women
People with long-term health conditions including asthma, diabetes, heart disease, or a weakened immune system
Anyone travelling to the southern hemisphere between April and September
Even if you don't fall into a high-risk group, a flu jab before a long trip is sensible. Flu can sideline you for a week or more, not something you want mid-holiday or mid-business trip.
You can get your flu jab at Icon Travel Clinic in Chigwell, Essex without a GP referral.
Do You Need a COVID-19 Vaccine for Travel in 2026?
The NHS has confirmed the eligible cohorts for its spring 2026 COVID-19 vaccination programme, which includes individuals aged 6 months and over who are immunosuppressed. For the general travelling public, no country currently requires proof of COVID-19 vaccination for entry, but staying up to date with boosters remains advisable for high-risk travellers.
What to check before you travel:
A small number of destinations retain COVID-related health declarations or requirements for specific activities such as cruises or access to certain medical facilities. Always check the FCDO travel advice page for your specific destination before you fly.
COVID-19 variants continue to circulate globally. Being vaccinated and boosted reduces the risk of severe illness, which matters more when you are far from home and healthcare access may be limited.
Travel insurance policies vary and some insurers may not cover COVID-related hospitalisation costs if you have not kept your vaccinations current. Check your policy carefully before travelling.
When a COVID booster may be recommended:
If it has been more than 12 months since your last COVID-19 dose and you are in a high-risk group, it is worth speaking to a clinician before you travel. You can check your vaccination record via the NHS App or by contacting your GP.
Flu vs COVID Jab: Do You Need Both?
You may need one, both, or neither depending on your situation. Here is a quick reference:
Your situation | Flu jab | COVID booster |
|---|---|---|
Healthy adult, travelling to Europe in summer | Consider | Check date of last dose |
Over 65 or high-risk condition | Recommended | Recommended |
Travelling to tropics or southern hemisphere | Recommended | Check date of last dose |
Immunocompromised | Strongly recommended | Strongly recommended |
Pregnant | Recommended | Discuss with clinician |
The 2026 Travel Security Situation: What Travellers Need to Know
Travel planning in 2026 requires extra caution beyond health vaccinations. The FCDO has highlighted heightened risks of disruption linked to Middle East conflict, shifting airspace restrictions and volatile weather, making 2026 one of the most complex years for international flying since the pandemic.
As of 2026, the FCDO advises against all travel to several countries including Afghanistan, Belarus, Haiti, Iran, Iraq, Israel, Mali, Niger, Palestine, Russia, South Sudan, Syria, Venezuela, and Yemen due to ongoing conflict or security risks.
The Middle East conflict has become the dominant factor in many FCDO advisories, particularly for destinations where UK travellers typically connect through Dubai, Doha, or Abu Dhabi on the way to Asia, Africa, and Australasia. Many airlines have adjusted flight paths to avoid conflict zones, leading to longer sectors, refuelling stops, or missed connections.
Practically, this means:
Always check the FCDO travel advice page for every country on your itinerary, including transit hubs, before booking
Travelling against Foreign Office advice may invalidate your travel insurance and limit UK consular support
Book flexible or refundable tickets where possible and keep essential documents and medications in cabin baggage
Sign up for FCDO email alerts for your destination so you receive real-time updates
Other Vaccines to Consider for Travel
Flu and COVID are often not the only vaccines worth reviewing before a trip. Depending on your destination, you may also need:
Yellow Fever required for entry to certain countries in Africa and South America, and only available at UKHSA-registered centres. Icon Travel Clinic is a NaTHNaC-approved yellow fever vaccination centre.
Hepatitis A recommended for most travel outside Northern and Western Europe, North America, and Australia. See our full travel vaccines page for details.
Typhoid advised for travel to parts of South Asia, Africa, and Central America where food and water hygiene standards may vary.
Anti-malarials not a vaccine, but essential medication for travel to malaria-risk regions.
Active health notices as of March 2026 include yellow fever in Venezuela, meningococcal disease in the Democratic Republic of the Congo and updated global dengue guidance. You can check country-specific vaccination requirements and outbreak alerts using TravelHealthPro, the official resource from the National Travel Health Network and Centre (NaTHNaC).
How Far in Advance Should You Get Vaccinated Before Travel?
As a general rule, aim to visit a travel clinic at least 4 to 6 weeks before departure. Some vaccines require more than one dose, and your immune system needs time to build protection after vaccination. That said, even last-minute vaccinations are better than none. Book an appointment at Icon Travel Clinic and we will advise you on the best course of action given your timeline.
