Malaysia Studies Dengue Vaccine as Cases Surge More Than 60% Nationwide

KUALA LUMPUR, AUGUST 2026 — Malaysia’s Ministry of Health is conducting a comprehensive assessment of a dengue vaccine as infections continue to rise sharply across the country.

Health Minister Datuk Seri Dr Dzulkefly Ahmad said the ministry is carrying out a cost-benefit analysis before deciding whether the vaccine should be added to the National Immunisation Programme (NIP).

One dengue vaccine has already been approved and registered by the National Pharmaceutical Regulatory Agency (NPRA) and is currently available at private healthcare facilities. However, Dzulkefly said its relatively high cost is among the factors that must be carefully considered before wider implementation.

Malaysia recorded more than 61,000 dengue cases up to Epidemiological Week 33, ending August 22, 2026. This represents a 60.8% increase compared with the same period last year. A total of 58 dengue-related deaths have also been reported.

In response to the surge, the Health Ministry has activated its dengue operations room and deployed personnel to identified hotspots, particularly in Kuala Lumpur and Selangor.

The ministry is also expanding the use of Wolbachia-infected mosquitoes as a biological control measure to reduce the population of Aedes mosquitoes capable of transmitting dengue.

Dzulkefly stressed that dengue prevention requires cooperation beyond the Health Ministry. Local authorities, government agencies and communities must also ensure residential areas and other premises do not become breeding grounds for Aedes mosquitoes.

The ministry will continue evaluating the dengue vaccine before making a final decision on whether it should become part of Malaysia’s national vaccination programme.
