Who Should Get Booster Dose In Malaysia?

The technical working group also evaluated the latest evidence, and introduced new recommendations for the COVID-19 vaccine booster dose.

These individuals are advised to receive a booster dose at least 3 months after their primary vaccination.

  • All senior citizens 60 years and above 
  • All adults 18 years and above who received all types of vaccines (Pfizer, AZ and CoronaVac), using the age de-escalation approach
    – 50 years old and above,
    – 40 years old and above, and
    – 18 years old and above
  • Individuals with co-morbidities
  • Residents and employees at long-term care facilities


Why Malaysia Reduced The Booster Dose Interval To 3 Months?

KKM made this decision based on the recent RECoVaM study, which showed the waning protection of COVID-19 vaccines, especially the Sinovac vaccine.

They were also concerned about the latest data on the Omicron variant, which showed greater transmissibility, higher viral binding affinity and higher antibody escape.

Evidence collected over the last 3 weeks showed that a booster dose can increase protection against the Omicron variant. And early research involving 21 million booster doses in the UK showed that they are safe.

In line with those results, regulatory bodies in the United Kingdom, Canada and Australia as well as panels of health experts now recommend that the booster dose vaccination should be given as early as three (3) months after completing the primary vaccine.
