Advisory to employers - Ingestion of overseas vaccination records for migrant workers

Issued on 18 August 2021
  1. Migrant workers who are vaccinated overseas with the Ministry of Health’s (MOH) approved list of COVID-19 vaccines1 can have their vaccination records ingested onto the National Immunization Registry (NIR) once they have (i) provided documentation proof of the vaccination and (ii) taken a serology test at a local clinic that returns with a positive result.

    What should I do as an employer if my migrant worker claims to be vaccinated overseas?
  2. You should arrange for your migrant workers to confirm their vaccination status at any of the medical centre or designated clinics in the sector where your worker resides, or has a Primary Care Plan with. You may also visit one of the private healthcare providers. Please remind your workers to bring along their overseas vaccination documentation on the day of the visit. They will be required to take a serology test and their overseas COVID-19 vaccination records will be accepted and ingested onto the NIR only when the serology test results are positive. This may take a few days and their vaccination status will be updated on FWMOMCare, Safe@Work and SGWorkPass when the results are made available.
  3. If any of your workers’ serology result is negative, his overseas COVID-19 vaccination records will not be accepted and ingested into the NIR and will be treated as an unvaccinated worker. In such situation, you can strongly encourage your migrant worker to take his vaccination in Singapore, which is available for free.
  4. Please note that the cost for verifying the overseas COVID-19 vaccination record and the serology test will be determined by the medical provider.
