Recognizing Overseas COVID-19 Vaccinations

We are offering service on serology testing and updating of overseas COVID-19 vaccination records into National Immunization Registry (NIR). This test cost $50-65 depending on the type of vaccine you received overseas.

We will perform the appropriate serology testing to confirm that you have undergone effective vaccination. The report will indicate a Positive (reactive) or Negative (non- reactive) result.

A positive serology result implies that you have undergone an effective vaccination and your vaccination record will be ingested into National Immunisation Registry (NIR). It takes 1 to 2 weeks for the TraceTogether (TT) app to be updated.

A negative serology result implies that the overseas vaccination was not effective and may not protect from COVID-19 infection. We advise that you take the vaccination in Singapore by checking your eligibility and registering at or call the MOH COVID-19 hotline at 1800-333-9999 for assistance.
