The Ultimate Thailand Travel Guide: 5 Things a Liverpool Pharmacist Wants You to Know Before You Fly

**1. Rabies is the one people underestimate, and Thailand is the reason.**

Thailand has a genuine rabies risk, and the exposures we hear about most are not from stray dogs in remote villages — they're monkeys at temples and viewpoints, and dogs on beaches. Rabies is effectively always fatal once symptoms appear, and the pre-exposure course does not make you immune. What it does is remove the need for rabies immunoglobulin after a bite, which is the part that is hard to obtain quickly in parts of Southeast Asia, and it cuts the post-bite treatment down to two doses.

The pre-exposure course is three doses. There's an accelerated schedule that fits inside a week if your departure is close. If you are going for more than a couple of weeks, going anywhere rural, cycling, running, or travelling with children — children are bitten more often and report it less — it is worth having.

**2. Hepatitis A and typhoid are the baseline, and they're the easy part.**

Both are food and water borne, both are recommended for essentially all travel to Thailand, and both are straightforward. Hepatitis A is a single dose before you go, with a booster 6–12 months later that takes you to around 25 years of protection. Typhoid is a single injection giving roughly three years.

If you've travelled before, check your records before assuming you need them again — a lot of people are already covered and don't realise.

**3. Japanese encephalitis is not for most Thailand trips — and that matters.**

This is where we most often talk people *out* of a vaccine. Japanese encephalitis is transmitted by mosquitoes that breed in rice paddies and around pig farming, mainly in rural areas, and mainly in the wet season. For a two-week beach or city trip it is generally not indicated. For a month or more in rural Thailand, an agricultural placement, or repeated long stays in the wet season, it moves onto the table.

It's a two-dose course over 28 days, with an accelerated 7-day option for adults. So it needs planning if it applies to you — which is exactly why the honest answer is worth getting early rather than late.

**4. Dengue is the risk with no easy answer.**

Dengue is present across Thailand and cases rise in the wet season. There is now a dengue vaccine licensed in the UK, but it is not a routine travel recommendation — it's a considered decision, weighted heavily by whether you've had dengue before, and by how long and how often you're travelling in dengue areas. Anyone selling it as a standard Thailand vaccine is overselling it.

For most travellers the meaningful protection is bite avoidance in the daytime, because the mosquito that carries dengue bites during daylight hours, unlike the malaria mosquito. Repellent with 50% DEET, and being deliberate about it in the afternoon, does more for you than most people expect.

**5. Malaria in Thailand is mostly a myth — except where it isn't.**

This surprises people. Bangkok, Chiang Mai, Phuket, Koh Samui and the main tourist routes are essentially malaria-free, and antimalarial tablets are not recommended for them. Risk is concentrated in forested border areas with Myanmar, Cambodia and Laos.

So the question isn't "am I going to Thailand", it's "am I going near those borders, and when". If you are, malaria prevention tablets are assessed and prescribed at the appointment — our clinic is run by an Independent Prescriber, so that's handled in the same visit rather than sending you to a GP.

**The practical bit**

Come in 4–6 weeks before you fly if you can, because rabies and Japanese encephalitis are courses rather than single doses. If you can't, come anyway — accelerated schedules exist for both, and hepatitis A and typhoid start working within days. Bring your itinerary, including the bits you think are irrelevant. Whether you're spending three nights in Pai changes the answer more than whether you're flying into Bangkok or Phuket.

This guide is written and reviewed by the pharmacists who run the clinic, against current NaTHNaC and UKHSA Green Book guidance. It is general information, not a personal recommendation — your own risk assessment happens at the consultation.
