For entry into Singapore, a valid yellow fever vaccination certificate is required from travellers (over one year of age) who, within the preceding six days have been in or have passed through any country at risk of yellow fever.
The International Certificate of Vaccination for yellow fever is considered valid 10 days after vaccination. From 1 May 2016, this certification, regardless of when it was conducted, will be valid for life*. Yellow fever vaccines are available at several clinics, including travel health clinics in public and private hospitals. Please consult your medical practitioner to review your suitability to receive the vaccine. Travellers who are exempted from yellow fever vaccination should possess an exemption letter, signed by an authorised health worker, to be considered for entry into Singapore.
*Prior to 1 May 2016, the certification was only valid for 10 years.
