The dengue vaccine works by training your immune system to recognise and fight off the dengue virus before it makes you seriously sick. It contains a harmless weakened version of the virus that teaches your body how to defend itself against the virus. Later, if you are exposed to the actual virus, your immune system can quickly respond, protecting you from severe dengue.

Studies show that twelve months after receiving the complete vaccine doses:

  1. Eight out of 10 individuals are protected from having dengue with symptoms, and
  2. Nine out of 10 individuals infected with dengue don’t get hospitalised.

Individuals aged four years and above can get vaccinated against dengue.
Moreover, you are highly recommended to get vaccinated if you:

  1. live / frequently visit areas where dengue cases are high, OR
  2. have had dengue fever, OR
  3. have any chronic illnesses

These conditions increase your possibility of getting dengue or severe dengue.

The vaccine is now available at private clinics and hospitals nationwide. You may find clinics that offer dengue vaccine at:
