Vaccinations for Singapore
There are no compulsory vaccinations for Singapore required by law for travellers from Western Europe to gain entry but certain vaccinations are strongly recommended.
For most standard tourists the usual recommended vaccinations for Singapore include cover against the childhood diseases (Tetanus and Diphtheria, Measles, Mumps and Rubella) as well as optional cover against Hepatitis A, Hepatitis B and Japanese Encephalitis.
If your passport shows that you have travelled via a yellow fever endemic country then the immigration authorities will usually check to see that you have received adequate vaccination cover against that disease.
Vaccinations for Singapore
10:13 Sat 2nd May, 2026All Travellers
Tetanus
Tetanus is contracted through contaminated cuts, bites and breaks in the skin. The vaccination provides cover for approximately 10 years in the majority of patients. It is frequently combined with cover against other diseases such as Poliomyelitis, Diphtheria and/or Pertussis.
Hepatitis A
Hepatitis A is a common disease in many of the hotter regions of the world and usually contracted through contaminated food and water. Cover against Hepatitis A can be given alone or combined with protection against Hepatitis B. Once completed, the Hepatitis A vaccination (given on two occasions 6 to 12 months apart) provides cover for approximately 25 years in the majority of patients.
Optional
Hepatitis B
Hepatitis B is a viral disease which is usually transmitted in a very similar fashion to HIV/AIDS through contact with infected body fluids (eg blood exposure and sexually). This vaccine can be combined with cover against Hepatitis A. The standard schedule for Hepatitis B is to administer the vaccine on days 0, 28 and 180. A more rapid schedule can be used in cases where cover is needed more urgently and this is administered on days 0, 7, 21 to 28 and also 365. Following either course (and not before completion) a blood test can be taken to confirm sufficient antibody protection. Where the correct level of antibodies are showing (>10iu) the vaccination is recognised to provide cover for life.
Japanese Encephalitis
Japanese Encephalitis is a viral disease transmitted through the bite of an infected mosquito. The vaccine is given on two occasions one month apart with a third dose at 12 months. Once completed the vaccine is thought to provide cover for between 2 to 3 years but possibly longer.
We advise starting your vaccinations 4–6 weeks before travelling from Ireland.
Dengue fever
Dengue fever is common in Singapore, with 4,000 to 5,000 reported cases every year. Before travelling, get up-to-date medical advice whether vaccination is required. When you arrive, avoid being bitten by mosquitoes by using bed nets and repellents, and wearing closed, long sleeves and trousers.
Yellow Fever
A yellow fever vaccination certificate is required for travellers arriving from, or transiting through, countries where yellow fever is a risk (primarily in Africa and South America).
Yellow fever vaccination is available at TMB clinics nationwide.
Air Pollution (Haze)
Seasonal “haze” from regional forest fires can cause poor air quality in Singapore.
Irish visitors should monitor updates from the Singapore National Environment Agency (NEA) for the latest advisories.
Bringing Medication into Singapore
Some prescription and over‑the‑counter medicines commonly used in Ireland are classified as controlled substances in Singapore.
Travellers must apply for prior authorisation from the Singapore Health Sciences Authority at least 10 working days before travel to bring these medications into the country.
