A vaccine against dengue?

Of late, there has been a sharp spike in the Aedes aegypti mosquito population, with the warmer-than-usual weather shortening the breeding and maturation cycles of the mosquitoes, as well as the incubation periods for the dengue virus.

From Jan 3-28 this year, the Health Ministry’s iDengue remote-sensing tool has recorded 12,897 cases nationwide, with 23 fatalities. Almost half the cases come from the hotspot state of Selangor, which tops the list with 6,267 cases.
