From 1 September 2025, employers of migrant domestic workers (MDWs) in households with children under seven who are not fully vaccinated must ensure their helper has measles immunity. This new rule of Mandatory measles immunity helps protect vulnerable young children from serious measles complications by reducing transmission risk in the home.
Why the Mandatory measles immunity rule matters
Measles is extremely contagious and can spread through the air, even when an infected person isn’t showing symptoms. Singapore’s high travel volume means imported cases remain a concern. By requiring helper immunity, the government aims to protect little ones who haven’t yet completed their two-dose vaccine schedule.
Who must comply with the Mandatory measles immunity rule?
New MDWs: At the point of work‑permit application, employers declare their helper’s immunity status.
Existing MDWs: During permit renewal from 1 September 2025, you’ll update the immunity declaration.
This applies only if there is at least one child below seven in the household who isn’t fully vaccinated against measles.
Your obligations under the Mandatory measles immunity requirement
Declare one of three options at application or renewal:
Your MDW is already immune or vaccinated against measles.
All children under seven in your household are fully vaccinated.
You have booked a vaccination appointment for your MDW.
Provide proof on MOM request—this can be vaccination records, serology test results, or documentation of past infection.
Review immunity status of existing MDWs ahead of renewal to avoid delays.
How to prove Mandatory measles immunity
Vaccination Records: Two doses of the MMR vaccine, spaced at least 28 days apart.
Serology Test: A blood test confirming immunity.
Past Infection Confirmation: Laboratory proof of a previous measles infection.
Keep these documents ready in case MOM requests verification.
Vaccination options and costs
Where to vaccinate: Any private GP clinic offering the MMR vaccine.
Vaccine schedule: Two doses, minimum four weeks apart, for full coverage.
Who pays: Employers bear all costs for vaccination or serology testing.
Tip: Call ahead to book appointments and avoid unnecessary trips.
