You may reschedule your appointments using the same booking link in the original SMS.

The Covid-19 vaccination is free for all Singaporeans and long-term residents in Singapore and no one should ask you for a payment to register for appointments. The link that is provided in the SMS should go to "vaccine.gov.sg". Only government officials can register for a gov.sg domain. Do not trust any other URLs that are not from a .gov.sg domain.

When in doubt, you should check with the agency who sent you the message to confirm the authenticity before responding to the message.

If you have been assessed to be ineligible for the Pfizer-BioNTech or Moderna COVID-19 Vaccines due to medical reasons, you may be able to get vaccinated later if data become available that it is safe to receive the vaccination, or you may be able to get vaccinated with other COVID-19 vaccines.

Upon successful registration of your interest , you will be sent an SMS with a unique booking link to make an appointment to be vaccinated. You will have 14 days from receipt of this SMS to schedule an appointment via the booking link.

Within the 14 days, you will have priority to schedule your appointment. If you have not booked a slot within the 14-day time limit, but are still keen to be vaccinated, you may re-register your interest and will be notified to make an appointment when there are slots available. You can re-register by clicking on the same unique link in the original SMS notification.

Please note that the 14-day limit applies to the time window given to make an appointment. It does not mean that you must be vaccinated within 14 days of receiving the SMS.

We aim to ensure that everyone who wishes to be vaccinated is able to do so at the earliest opportunity. As vaccine supplies are limited at the outset, holding slots for those who may need more time to decide whether to get vaccinated would deprive others of a slot.

While we have prioritised certain groups for vaccination, we will move on to the next priority group to give others who wish to be vaccinated the opportunity to do so quickly.

As part of the two-step booking process, individuals must first (i) register their interest to be vaccinated at vaccine.gov.sg, and then (ii) receive a Short Message Service (SMS) invitation (within a few days to up to three weeks after registration) with a personalised booking link to book their vaccination appointments.

This two-step process is necessary to ensure that we have verified the correct mobile number being used by the interested individuals to process their bookings, and more importantly, allow us to balance the demand for vaccination slots with our existing vaccine supplies. Our supply of vaccines remains limited by the ability of vaccine manufacturers to deliver at a faster rate, given the high levels of global demand. This may result in limited booking slots, and hence a longer wait for some before they receive their booking SMS. As more supplies arrive, we will progressively invite more individuals to book their appointments.

The dosing regimen is at day 0 and 21 (i.e. 21 days apart) for the Pfizer-BioNTech vaccine, and day 0 and 28 (i.e. 28 days apart) for the Moderna vaccine. You must receive both doses to have the full vaccine protection.

• Bring your IC for both appointments
• Please turn up on time
• Please wear short sleeved attire, or sleeves loose enough to be rolled up
• If you are unwell, stay home and postpone your appointments

Please do not go for the appointment. You should only take the vaccination when you are well.

If you have not taken your 1st dose, cancel and rebook both appointments using the same booking link issued by SMS. If you have taken your 1st dose and wish to reschedule your 2nd dose, please call MOH at 1800 333 9999.

The vaccine will be injected into your upper arm. To make this easier, you are advised to wear short sleeves, or sleeves loose enough to be rolled up.

The COVID-19 vaccines used are currently Pfizer-BioNTech and Moderna .

The vaccine has been assessed to be safe for use. However, you may experience common side effects, similar to other vaccines. Most side effects are mild or moderate, and usually get better within a few days. The table below lists some common side effects that have been reported with this vaccine, and how to manage them.

See a doctor if:

• The side effects persist or get worse
• The fever persists for more than 48 hours (2 days)

In very rare cases, this vaccine can cause a severe allergic reaction. Signs of a severe allergic reaction include: difficulty breathing, swelling of your face, throat, eyes or lips, a fast heartbeat, dizziness and weakness, a bad rash all over your body. If you experience a severe allergic reaction, seek medical attention immediately. Call 995 or go to the nearest A&E immediately.

If you experience a severe allergic reaction, seek medical attention immediately. Call 995 or go to the nearest A&E immediately.

You must receive both doses to have the full vaccine protection. Protection for a single dose has not been formally studied for the COVID-19 Vaccines, but based on vaccines for other diseases, completion of the recommended doses of the vaccine is required for long-term protection. To make an appointment for your 2nd dose, please call MOH at 1800 333 9999.

The Islamic Religious Council of Singapore (MUIS) has permitted COVID-19 vaccines for Muslim use. Please refer to MUIS’ religious position on the COVID-19 vaccine for more information.

There is no evidence at this time suggesting that the Pfizer-BioNTech and Moderna’s vaccines do not protect against specific COVID-19 strains, including the UK’s new reported variant. HSA and the EC19V are closely monitoring this issue.

All vaccines requiring 2 doses should be completed using the same brand. There is no data at this time to support switching vaccines between dose 1 and dose 2, except for very specific medical conditions, and it is therefore not advisable to do so.

There is no recommendation at this time for someone who has completed 2 doses of COVID-19 vaccine to get further vaccinated with another brand of COVID-19 vaccine.

The Ministry of Health will provide recommendations as follow-up data become available from studies, if a booster is required later on.
