Benefits of dengue immunization

Chairperson of the National Commission on Post-Immunization Follow-up Events (KIPI) Prof. Dr. dr. Hinky Hindra Irawan Satari, Sp.A, Subsp.IPT, M.TropPaed explained that dengue immunization is useful for preventing severe infection and death from dengue fever.

“Immunization with the dengue vaccine can prevent infection. Even if you do get hit, you won’t go into shock, you won’t be in the ICU, you won’t be bleeding,” said Hinky, as quoted from BetweenThursday (23/2/2023).

Apart from dengue immunization, Hinky explained, increasing the body’s resistance to prevent dengue fever can also be done with a healthy diet with balanced nutrition.

Types of dengue immunization

In Indonesia, currently there are two types of vaccines used for dengue immunization, namely:

This dengue vaccine is a type of chimeric yellow fever tetravalent dengue vaccine (CYD-TDV).

The Dengvaxia vaccine contains attenuated tetravalent dengue virus. However, this vaccine is effective if given to children aged 9 to 16 years who have previously been infected with the dengue virus.

Dengue immunization still needs to be given to children who have had dengue fever before because when infected with dengue virus, it is impossible for a child to be exposed to four types or serotypes of dengue virus at once.

Usually, children are only exposed to one serotype of the virus when they have DHF. So, when given a dengue immunization containing 4 dengue serotypes, children can develop immunity against other dengue serotypes that have not yet infected the body.
