The Moderna COVID-19 vaccine has been authorised for use in Singapore in individuals aged 18 years and above.

The first shipment arrived in Singapore on 17 February 2021. 

Details of the Moderna COVID-19 vaccine

  • For individuals aged 18 years and above
  • Two doses required, administered 28 days apart
  • High vaccine efficacy of 94%

Two groups of experts from the Health Sciences Authority’s Medicines Advisory Committee and Panel of Infectious Diseases Experts were consulted during the review to ensure that the vaccine is safe, efficacious and of good quality based on the data submitted to-date. The benefits outweigh the known risks for the Singapore population.

Who should not receive the vaccine

The following groups should not receive the Moderna COVID-19 vaccine as the safety and efficacy data for these groups are not available yet.

  • Pregnant women
  • Severely immunocompromised persons
  • Those under the age of 18

As with all vaccines, side effects like swelling at the injection site, fatigue and fever are common. There will always be a small proportion of susceptible persons who may experience severe allergic reactions upon vaccination.

They include those with a history of anaphylaxis (rapid onset of severe allergic reactions) or severe or multiple allergies to medicines and food.

In such cases, immediate medical attention should be sought. As a precautionary measure, anyone with a history of anaphylaxis or severe or multiple allergies to medicines or food should not receive the Moderna COVID-19 vaccine.

Persons who develop anaphylaxis or severe allergic reactions to the first dose of the COVID-19 vaccine also should not receive the second dose.

Vaccine supplies

More vaccines from Moderna and Pfizer-BioNTech will arrive over the course of this year. Supplies will be monitored closely to ensure that there will be enough vaccines for all Singaporeans and long-term residents in Singapore.
