| Why is there a need for booster dose? | Similar to the development of natural immunity after being infected by
COVID-19, the immunity formed after completion of vaccination decreases after a certain period
of time. Protection against COVID-19 infection wanes 3–5 months after
immunisation, according to RECoVaM research.
Administration
of booster dose is highly recommended to restore the protection against COVID-19 to an optimal level.
This is to ensure an optimal period of coverage is obtained by the vaccine recipients.
Get a booster dose when it is your turn!
|
|---|
| Who is eligible for a booster dose? | All Malaysian residents aged 18 and above who have completed vaccination
at least 3-6 months ago.
Priority will be given to:
• Frontliners
• Individuals with comorbidities
• Residents and workers of long-term healthcare facilities such as nursing homes and
old
folks’ homes
• Pregnant women
• Individuals who need to travel abroad

| How is the interval between a 2-dose primary series and a booster dose
measured?
| The interval between a 2-dose primary series and a booster dose varies
depending on the type of primary dose that you had received. Vaccines that are used for booster
doses are Pfizer-BioNTech, Sinovac, and AstraZeneca.
Booster doses can be given either with the same type (homologous) or different type
(heterologous) based on advice from the Technical Working Task Force and Director General of
Health's circular No.1/2022.
The interval measured is in calendar months, regardless of the date.
• Sinovac recipients: 3 months after the second dose
• AstraZeneca, Pfizer-BioNTech recipients: 3 months after the second dose
If recipient is medically contraindicated to an mRNA vaccine, they will be offered other vaccine
alternative as per medical advice.
|
|---|
| Does my booster dose need to match my first two
doses?
| The “COVID-19 vaccine effectiveness assessment in Chile”
study released by the Chilean government at a World Health Organization (WHO) consultation on
October 25, 2021 showed that the combination of the Sinovac vaccine with either
Pfizer-BioNTech or AstraZeneca as the booster dose increases vaccine efficacy.
• Pfizer-BioNtech as booster dose: Vaccine efficacy increases from 54% to 95%
• AstraZeneca as booster dose: Vaccine efficacy increases from 54% to 94%
• Sinovac as booster dose: Vaccine efficacy increases from 54% to 74%
 |
|---|
| What is the dosage for a booster dose? | The dosage for the Pfizer-BioNTech COVID-19 booster dose is 0.3ml.
Sinovac recipients will receive the same booster dosage.
|
|---|
| What vaccine will Sinovac recipients receive for a booster dose? | In Malaysia, Sinovac recipients may receive a booster dose of either
Pfizer-BioNTech (heterologous) or Sinovac (homologous) 3 months after their second dose.
Whether a booster dose is homologous or heterologous, there is an increase in
vaccine effectiveness when it is given to an adult.
|
|---|
| Is a Pfizer-BioNTech booster dose the same formulation as the existing
vaccines?
| For Pfizer-BioNTech recipients: Yes, it is the same as the current
COVID-19 vaccines.
For Sinovac recipients: It is a different vaccine type as the Sinovac COVID-19 vaccine is an
inactivated virus, while Pfizer-BioNTech is an mRNA vaccine. Sinovac recipients may be given a
heterologous booster dose of Pfizer-BioNTech
to improve the vaccine efficacy.
|
|---|
| If I need a booster dose, are the COVID-19 vaccines working? | Yes, the approved COVID-19 vaccines continue to be effective at
preventing severe illness, hospitalisation, and even against the COVID-19 variants.
|
|---|
| Are the booster doses safe? | Yes, all COVID-19 vaccines approved by the National Pharmaceutical
Regulatory Division (NPRA) for use in Malaysia are safe and effective.
NPRA is the body responsible for evaluating vaccines to be registered in Malaysia. So far, the
COVID-19 vaccine for Malaysia has been given conditional approval based on strict compliance
with the assessment of scientific, clinical, and technical data. The Drug Control Authority
(PBKD) will approve the use of the vaccine for Malaysia
based on the results of the NPRA assessment.
|
|---|
| What is the difference between additional dose and booster dose? | Additional dose is given to those who may not have responded adequately
to the primary vaccination series (immunocompromised). It is given at least 28 days after
completing the primary vaccination series.
Booster dose is given to those
who likely had an adequate initial response but whose immunity may have waned over time (waning
immunity). It is given 3 months after completing the primary vaccination series.
|
|---|
| What should I do before receiving my booster dose at Pusat Pemberian
Vaksin (PPV)? | Make sure that you:
• Have sufficient sleep
• Have taken breakfast or lunch before going to the PPV
• Are healthy and without symptoms of illnesses on vaccination day
• Wear proper attire
• Wear protective mask
• Bring along your identification card
• Bring along your vaccination record card to prove that you are fully vaccinated
|
|---|
| What should I pay attention to after receiving my booster dose? | There is no evidence to indicate that individuals can develop health
complications after receiving the booster dose.
The side effects of getting a booster dose are similar to those that occur after primary
vaccination series, and most
side effects are mild to moderate.
An individual may experience common side effects such as pain, redness or swelling in the
shoulder muscle area where the injections are given, fatigue, headaches, muscle pain, chills,
fever, and
nausea. On a positive note, these symptoms will usually get better after a few days.
• If you experience any allergic reaction (AEFI) after receiving the booster dose,
submit
a report via the MySejahtera application.
• Visit the nearest clinic or hospital if you are experience a severe allergic
reaction.
• Avoid strenuous activities for one week after receiving the booster dose.

|
|---|
| Will a booster dose be given annually? | The Ministry of Health will review the data from time to time before
deciding whether or not to make the COVID-19 vaccination an annual immunisation. It will depend
primarily on the vaccine’s effectiveness and safety profile.
