Vaccinations for Malaysia: what NaTHNaC actually recommends
By Covered Abroad Research Desk · Last verified July 2026
What NaTHNaC recommends for Malaysia
The reference point here is NaTHNaC — the National Travel Health Network and Centre, which writes the UK's country-by-country travel health guidance. Its Malaysia page is the thing to read before a pharmacy appointment.
Routine schedule first. Be up to date with the courses and boosters recommended in the UK for your age and medical history, including MMR and diphtheria-tetanus-polio.
Hepatitis A is recommended for all previously unvaccinated travellers.
Hepatitis B. Malaysia is "considered to have an intermediate or high prevalence of hepatitis B". Vaccination could be considered for all travellers, and is recommended where activities or medical history raise the risk.
Japanese encephalitis. JE "occurs throughout Malaysia, with year-round risk". The highest-risk area is Sarawak, with a seasonal peak between October and December. Risk rises with rural travel, rice fields and longer stays.
Tetanus. Where medical facilities may be limited, a booster is recommended if the last dose was more than ten years ago — even if you have already had five doses.
There is also a stated risk of chikungunya, for which there is no routine traveller vaccine and bite avoidance is the control.
Borneo is treated as a separate country
This is the detail most summaries flatten, and it matters if you are going to Sabah or Sarawak.
NaTHNaC does not publish one Malaysia profile. It maintains Malaysia and Borneo (Malaysia) as separate country pages, because the risk picture differs. Sarawak is already flagged as the highest-risk area for Japanese encephalitis within the main profile.
If your move or trip involves East Malaysia, read the Borneo page rather than assuming the peninsular advice transfers.
60-second check
Not sure the policy you have meets your destination's written rule? Run it through the policy check now, before you build the rest of the file around it.
Check my policyMalaria: low risk, and that changes the advice
People often arrive expecting to be told to take antimalarials. For mainland Malaysia, generally they are not.
NaTHNaC states there is a low risk of malaria in mainland Malaysia, with "awareness of risk and bite avoidance recommended". Antimalarials may still be considered in exceptional circumstances — long-stay travellers visiting friends and relatives, or those at higher risk of severe complications, including people over 70, the immunosuppressed, pregnant women and young children. The guidance is explicit that the final decision rests with the travel health advisor and the traveller after an individual risk assessment.
The rule worth memorising applies after you get home: a fever of 38°C or higher more than a week after being in a malaria risk area — or any symptoms suggestive of malaria within a year of return — means seeking immediate medical care.

Yellow fever: no risk, but a certificate requirement
These two facts sit together awkwardly and are frequently confused.
There is no risk of yellow fever in Malaysia. There is, separately, a certificate requirement: under the International Health Regulations a yellow fever vaccination certificate is required from travellers over one year of age arriving from countries with risk of transmission — and from anyone who has transited for more than 12 hours through an airport in such a country.
So the trigger is your routing, not Malaysia. A long layover on the way can create a requirement that a direct flight would not.
Where vaccinations meet the policy
Two things are worth knowing, and the second one surprises people.
Vaccination cover is thin and conditional. On Regency's plans there is no vaccinations benefit at all on the Major Medical or Standard tiers. Comprehensive and Fully Comprehensive carry one, capped, and Comprehensive applies co-insurance to it. The benefit covers only vaccinations directly related to overseas travel requirements.
Skipping a required vaccination is an exclusion. The policy excludes claims arising from failing to get required inoculations or vaccinations. That turns the pharmacy appointment from an expense into a condition — the cost of the shot is small, and the consequence of not having it can be a declined claim on something much larger.
Check the certificate, and keep it.
What we can and cannot help with
To be clear about scope: we are not a travel clinic and nothing here is medical advice — your vaccination schedule is a conversation with a nurse or pharmacist who can see your records. We are an insurance introducer for international health and life cover for people.
What we can do is the cover that sits behind the trip. Pre-existing conditions are excluded and cover is governed by the Regency Assurance policy wording.
