[Updated 7 November 2022]

[New] Extension of Bivalent Booster to Younger Age Groups


From 7 November 2022, eligible individuals aged 18 to 49 years will progressively be invited to receive an additional dose of bivalent vaccine, especially those who have yet to complete their minimum protection series.


Individuals who are eligible will receive an SMS with a personalised booking link to make an appointment at one of the Joint Testing and Vaccination Centres (JTVCs).


Individuals in the 40 to 49 age group will first be invited in the initial phase, before gradually moving on to the lower age groups. To avoid overcrowding the JTVCs, only persons aged 50 years and above and healthcare workers will be allowed for walk-ins. To locate the nearest JTVC and their operating hours, please visit here.


The original Moderna/Spikevax vaccine has been updated with a bivalent version to offer better protection against newer COVID-19 variants since 14 October 2022 for persons aged 18 years and above receiving any vaccination.


The Pfizer/Comirnaty bivalent vaccine is undergoing evaluation and should be available end of this year.


The Pfizer-BioNTech/Comirnaty bivalent Original-Omicron BA.4/5 vaccine has been approved locally for use in individuals aged 12 years and above. Supplies are expected to arrive end of this year and more details will be shared later.

[Updated] Achieving Minimum Protection and an up-to-date vaccination status

Under the up-to-date vaccination arrangement, individuals are advised to:

  1. Ensure they achieve minimum protection. Persons aged 5 years and above should complete three mRNA or Novavax/Nuvaxovid doses, or four Sinovac-CoronaVac doses to achieve minimum protection. 

  2. Persons aged 18 and above should receive an additional booster dose between five months to one year from their last dose after achieving minimum protection, for their COVID-19 vaccination status to be kept up to date. The updated bivalent vaccine is recommended for this additional booster dose. Please refer to the Annex here for more info.

Booster recommended for individuals who received Sinovac-CoronaVac primary series

The EC19V now recommends that persons aged 18 and above who received only three doses of Sinovac-CoronaVac to receive the updated Moderna/Spikevax bivalent vaccine, or the Pfizer-BioNTech/Comirnaty or Novavax/Nuvaxovid vaccine. This will allow them to achieve minimum protection.

Sinovac-CoronaVac vaccine is also allowed as booster doses, without a proof of medical ineligibility to mRNA or Novavax/Nuvaxovid vaccines.

Booster recommended for children aged 5 to 11 years

The EC19V also recommends that children aged 5 to 11 years receive one booster dose of the Pfizer-BioNTech/Comirnaty vaccine, from five months after the second dose of their primary vaccination series to sustain protection against severe illnesses.

From 25 October 2022, parents or guardians of eligible children in this age group will receive a personalised booking link in an SMS notification to book an appointment for their child or ward’s Pfizer-BioNTech/Comirnaty booster dose.

All children in this age group must be accompanied by their parent/guardian on the day of vaccination. Student Identification or Health Booklet and Birth Certificate, or Passport/Singpass are required for verification at the appointment.

Vaccination recommended for children aged 6 months to 4 years

From 25 October 2022, children aged 6 months to 4 years are recommended to receive two doses of the Moderna/Spikevax vaccine eight weeks apart as part of their primary vaccination.

Parents or guardians of this age group may start registering interest for their child or ward to receive the Moderna/Spikevax vaccine here from 18 October 2022 onwards. An SMS invitation will be sent to the mobile number indicated in the registration form within three to five working days.

All children in this age group must be accompanied by their parent/guardian on the day of vaccination. Student Identification or Health Booklet and Birth Certificate, or Passport/Singpass are required for verification at the appointment.

The three-dose Pfizer BioNTech/Comirnaty vaccine for children in this age group should be available end of the year.

More info on the five dedicated Vaccination Centres (VCs) offering the Moderna/Spikevax for those aged 6 months to 4 years and Pfizer BioNTech/Comirnaty vaccines for those aged 5 to 11 years can be found in the Annex here.

Second booster shot for medically vulnerable persons aged 18 and above

Persons aged 18 years and older, who are medically vulnerable to severe COVID-19, can receive their second booster without the need for a physician’s referral. From 1 July 2022, medically vulnerable persons with specific health conditions[1] may self-declare their health conditions to receive their second booster by walking into any Vaccination Centre, Public Health Preparedness Clinics (PHPCs) and polyclinics that offer vaccinations. 

Other medically vulnerable persons will continue to be able to receive the second booster by providing a referral memo from their treating doctors.

[1] These medical conditions include chronic diseases of the heart, lungs, kidneys, liver and other organ systems. Please refer to the Annex here for more info. 

Private Vaccination Programme Extended to All

The Private Vaccination Programme (PVP) has been extended to all individuals in Singapore aged 18 and above, including local residents. This will allow individuals who wish to take additional vaccine doses, but who do not quality under the National Vaccination Programme, to do so based on a doctor’s assessment. Vaccinations under PVP will be at the individual’s own cost. Please refer to vaccine.gov.sg for the updated list of PVP providers.

Extending the Recommended Primary Vaccination Series Dosing Interval

The recommended dosing interval between the first two doses of a COVID-19 primary vaccination series had been set at 21 to 28 days depending on the vaccine used. There is now more evidence that an extended interval may confer better immune response and vaccine effectiveness.

EC19V now recommends the dosing interval to be extended to eight weeks between the first two doses of the primary vaccination series for all COVID-19 vaccines[1] available under the National Vaccination Programme, for those who have yet to be vaccinated with their primary vaccination series.

Individuals particularly at risk of exposure to COVID-19 or more susceptible to severe disease may still receive the doses earlier than the eight-week interval but not less than the previously established minimum intervals[2].

[1] Vaccines available under the National Vaccination Programme are: Pfizer-BionTech/Comirnaty, updated Moderna/Spikevax bivalent vaccine (from 14 October 2022 onwards), Novavax/Nuvaxovid and Sinovac-Coronavac.
[2] The minimum intervals that the first two doses of the vaccines should be taken are: 21 days for Pfizer-BioNTech/Comirnaty and Novavax/Nuvaxovid, 28 days for Moderna/Spikevax and Sinovac-CoronaVac.
