Post-vaccination Matters

Updated 31 May

Are there any side effects? What should I do if I suffer from any side effects?

A:

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.

Side EffectsHow to Manage
Pain, redness, swelling at the injection site

Those with fever are advised to self-isolate at home until the fever subsides.


Paracetamol 1 to 2 tablets for the other side effects every 6 hours as needed.
Fever, chills
Headache, muscle pain, joint pain
Tiredness
Rest
Lymph node swelling at neck or arms
Usually gets better by itself in a week or so


See a doctor if:
• The side effects persist or get worse
• The fever persists for more than 48 hours (2 days)
Respiratory symptoms such as cough, runny nose, sore throat, shortness of breath or loss of sense of taste and smell develops.

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.

How long do we have to observe and report the side effects from the vaccine? Which side effect takes the longest to manifest?

A:

Most side effects will resolve within 3 days. Though uncommon, lymphadenopathy (lymph node swelling) can be vaccine-related and takes around 7 to 10 days to resolve.


 

Would there be post-vaccination monitoring in place, e.g. will some staff and residents continually be tested for COVID-19 virus antibodies, to determine durability of the vaccination response?

A:

As a condition for the interim authorisation under PSAR, vaccine companies including Pfizer-BioNTech are required to monitor the longer term efficacy of the vaccine to determine the duration of protection against COVID-19, as well as follow up on the safety of the vaccine for a longer period of time to determine its full safety profile. Vaccine companies must continue submitting the longer term follow up data to HSA to assure the continued effectiveness and safety of the vaccine. HSA will actively review the data to ensure that the benefits of the vaccine continue to outweigh the known risks. When sufficient data is available for full registration, the companies will be required to file an application to transit the status of the product from PSAR interim authorisation to full registration.

Research studies will be conducted to better understand the impact of the COVID-19 vaccination, including the durability and the extent the vaccine is able to prevent transmission. Hence, vaccinated persons may be recruited for such studies.


 

With COVID-19 vaccines deployed, is there still a need for public health measures such as donning of full PPE among healthcare workers?

A:

We are still monitoring clinical data on the duration of the vaccine’s protection and its effectiveness in preventing transmission. As such, until a significant proportion of the population is vaccinated, we will need to continue to practice public health measures, such as safe distancing, mask wearing and good hand hygiene, so that we can continue to protect ourselves and our loved ones.


Updated 31 May

What sorts of activities will be vaccinated persons be allowed to do (e.g. karaoke)? Will they be exempted from measures such as pre-event and/or pre-departure/ entry to Singapore testing? What about public health measures such as quarantine?

A:

Vaccinated persons should still continue to adhere to public health and general safe management measures.

 

While there is evidence that COVID-19 vaccines are effective in preventing symptomatic disease, the extent of their ability in preventing transmission to others is still being studied.


 

Can I use the proof of vaccination for travel purposes? Will it be recognised by other countries?

A:

Jurisdictions have different travel restrictions and requirements, please verify jurisdictions’ restrictions and requirements before you travel.

 

 

Will existing measures such as RRT, ARI testing and donning of PPE by staff still be required for those who are vaccinated?

A:

Public health measures, such as safe distancing, mask wearing and good hand hygiene, should continue to be practised. MOH will continue to assess the local situation in the review of the various public measures. Amongst others, this will take into account considerations such as the take-up of vaccine in the population, the availability of data on the vaccine’s duration of protection and the extent of its ability to prevent transmission.


 

What happens if I develop an allergic reaction to my first dose?

A:

If you experience a possible allergic reaction to the first dose (e.g. eye or lip swelling, hives, generalised skin rashes, breathlessness), you should seek medical attention. Persons with an allergic reaction to the first dose are advised not to take the second dose and should cancel the appointment for it. Fever, chills, muscle pain, headaches, injection site pain are not allergic reactions. We will track this group of individuals and update when there are suitable vaccines available.


 

Where can I see my vaccination records?

A:

Vaccination records are kept electronically in the National Immunisation Registry, as well as on apps such as TraceTogether and HealthHub. You can also refer to your physical vaccination card that is given to all vaccinated individuals. These are for your own reference, to check if you are vaccinated.


Updated 31 May

I have been vaccinated. Why is my status reflected as "Not Vaccinated"?

A:

To date, only the Pfizer and Moderna vaccine is approved for use in Singapore. Individuals who have been vaccinated with other COVID-19 vaccines overseas will not have their records reflected in our system.


If you had received the Pfizer/Moderna vaccine and your status is reflected as "not vaccinated" or "in progress", it may be due to the following reasons:

 

  • You have not completed all doses of the vaccination. You require two doses to complete the vaccination programme.
  • It has been less than 14 days since you received the second dose of the vaccine. The vaccine will only fully take effect 14 days after your second dose.
  • The interval between your vaccination doses is outside of the recommended minimal interval for the vaccine. Please refer to www.vaccine.gov.sg for more information on the recommended interval between doses.

 

Please vist www.vaccine.gov.sg for more information or contact 1800-333-9999 for assistance.

 

Can I use my physical vaccination card for travel purposes?

A:

The physical vaccination card that is given to all vaccinated individuals is not meant to be used for travel purposes. We are actively engaging international counterparts and monitoring global developments on the development and recognition of digital vaccination certificates for travel purposes. Travelers should also take note of the latest travel advisory for Singaporeans and residents of Singapore published by MOH (https://www.moh.gov.sg/covid-19).

 

 

How can I prove that I have been vaccinated?

 A:

For events which require pre-event testing (PET), the event organiser or venue staff will be able to retrieve your vaccination status directly from MOH’s database as part of PET status checks using the SafeEntry Business app. Attendees at these events will need to use the updated TraceTogether (TT) app or working TT token.

The physical vaccination card that is given to all vaccinated individuals is not meant to be used for travel purposes/ proof of vaccination. For purposes of travel, you can request for a digital vaccination certificate from Notαrise (https://www.notarise.gov.sg). This will be sent to your email and/or Singpass app, and can also be printed out. Please be aware that the use of this digital vaccination certificate is subject to the prevailing entry requirements of your destination country.

 

Travelers should check the MFA website (https://www.mfa.gov.sg/where-are-you-travelling-to) for the latest travel advisories to other countries/ regions, as well as the immigration authority or embassy of the destination country/ region on the relevant health requirements imposed on travelers from Singapore. Travelers should also take note of the latest travel advisory for Singaporeans and residents of Singapore published by MOH (https://www.moh.gov.sg/covid-19).
