The Philippine Congress has started an investigation into the purchase of a dengue vaccine, the world's first, which has been administered to about 700,000 Filipino children since 2016.

A legal team will be assisting the task force to look into the accountability of Sanofi Pasteur, the manufacturer, which initially claimed the vaccine was safe and effective.
