The findings of the study include the following:

Dengue could be prevented by about 61%

There were no safety problems reported

“As a pharmaceutical company, they [Takeda] have found that their vaccine works well in some cases. But there are concerns too. For example, in the Philippines, children who received the dengue vaccine [Sanofi’s Dengvaxia] developed a more severe condition afterward.[So], we cannot use it until independent bodies like GAVI, the World Health Organization, or Unicef recommend it. Says Prof MA Faiz, former director general, Health Services at DGHS.

This is a common worry among experts. Many experts are apprehensive about the effectiveness of the new vaccine against four different strains of the dengue virus.

Currently, the vaccine has approval from US FDA. Presently, the vaccine can only be given to kids and teenagers between 9 to 16 having a lab-confirmed previous dengue-virus infection. Also, they need to be from an area where dengue is an endemic disease.
