Most travel vaccines are still worth getting, even if your trip is just two weeks, one week or even a day away. Vaccines such as hepatitis A and typhoid begin building protection within days, so getting vaccinated late is usually far better than not getting vaccinated at all.
Every week, travellers across the UK realise their holiday is just around the corner, but their travel vaccines have slipped their mind. If that sounds familiar, don’t panic. In this blog, we’ll explain which last-minute travel vaccines can still help at 2, 1 or 0 weeks’ notice, and what you should do if you’re flying within days.
Quick answer
Yes, most travel vaccines are still worth having even at short notice. Hepatitis A, typhoid, cholera and meningitis ACWY can all build good protection within one to two weeks, and a same-day appointment is still worthwhile in most cases. The one clear exception is yellow fever, since its international certificate only becomes valid ten days after vaccination.
Why Timing Matters for Travel Vaccines
Travel vaccines need time to help your immune system build protection, which usually takes around one to four weeks. The NHS recommends speaking to a pharmacist or GP at least four to six weeks before travelling, but this is the ideal timeframe rather than a strict deadline.
Your body begins responding as soon as you receive a vaccine. While protection develops gradually, getting vaccinated even shortly before your trip can still provide benefits, as your immune system may already be building defences by the time you reach your destination, and during the period when exposure risk is highest.
Travel Vaccines That Still Work at 2 Weeks’ Notice
Two weeks is more time than most people think. Getting travel vaccines two weeks before travel gives many single-dose jabs enough time to reach strong levels of protection, including:
| Vaccine | Notice Needed | Notes |
|---|---|---|
| Hepatitis A | 2 weeks | Offers good protection within two weeks of one dose |
| Typhoid | 2 weeks | Effective from around two weeks after vaccination |
| Cholera (oral) | 2 weeks | Useful for certain high-risk regions |
| Meningitis ACWY | 2 weeks | Required for Hajj and Umrah pilgrims, and effective within two weeks |
Timings above are a general guide only. Your pharmacist will confirm what is suitable for your destination and health history.

Flying in a Week? Vaccines Worth Getting at Short Notice
If you are thinking, “I’m flying in a week; what vaccines can I still get”, the honest answer is most of them. Hepatitis A and typhoid still provide meaningful protection at seven days, and combined jabs can cover both in one appointment.
One week is also enough to start a rabies or hepatitis B rapid course in some cases and to collect antimalarial tablets, which are not vaccines but are often the most urgent protection of all for parts of Africa, Asia and South America.
Same-Day Travel Vaccines: What Helps at 0 Weeks
Even on the day before you fly, vaccination is rarely pointless. Same-day travel vaccines such as hepatitis A still offer partial early protection, and because hepatitis A has a long incubation period, a jab at departure can still prevent illness during and after your trip.
A same-day appointment also allows a pharmacist to:
- Supply antimalarials that start working within one to two days.
- Provide advice on food, water, and insect-bite precautions.
- Check whether any routine boosters, such as tetanus, are due.
If you forgot to get travel jabs before your holiday, a quick consultation is still one of the most valuable things you can do before boarding.
How Late Is Too Late for Travel Vaccines?
For most single-dose vaccines, it is never truly too late, right up to the day of travel. The only real limits apply to multi-dose courses and vaccines with strict timing rules.
Vaccines That Need Longer Lead Times
Some vaccines cannot be rushed. Yellow fever certificates only become valid ten days after vaccination, which matters because some countries legally require proof of it at the border. Standard courses for rabies, hepatitis B and Japanese encephalitis also need three to four weeks, though accelerated schedules sometimes help.
Why Partial Protection Still Beats None
Partial immunity significantly reduces your risk of serious illness compared with travelling unprotected. UK travel health guidance supports vaccinating travellers even when they are booking close to departure, as some protection is better than none.

Frequently Asked Questions
Q. Can I get travel vaccines 2 weeks before travel?
Ans. Yes. Two weeks is enough time for hepatitis A, typhoid, cholera and meningitis ACWY vaccines to build strong protection before most trips.
Q. Is one week too late for travel vaccinations?
Ans. No. Hepatitis A and typhoid vaccines still offer worthwhile protection at one week, and antimalarial tablets can be started immediately.
Q. Are same-day travel vaccines effective?
Ans. Partially, yes. Vaccines given on the day of travel still trigger an immune response that builds during your trip, and for hepatitis A this early protection is clinically meaningful.
Q. Which travel vaccine cannot be done last minute?
Ans. Yellow fever. The international certificate only becomes valid ten days after vaccination, so countries requiring proof will not accept a same-day jab.
Q. Do I need a GP appointment for last-minute travel vaccines?
Ans. No. Pharmacies such as Anna Pharmacy can assess, prescribe and vaccinate you in a single visit, often on the same day.
Q. What if my trip is in two days and I have had no vaccines at all?
Ans. Book an urgent pharmacy travel consultation. You can still receive hepatitis A and typhoid vaccines, start antimalarials and get tailored safety advice before you fly.
