The Dengvaxia controversy, Dengvaxia issue, or Dengvaxia mess is an ongoing controversy about the use of anti-dengue vaccine Dengvaxia in the Philippines. In late November 2017, the Department of Health suspended a school-based vaccination program utilizing French drug-based vaccine maker Sanofi Pasteur's Dengvaxia vaccine because reports circulated that several children died from various complications allegedly attributed to the dengue vaccine.
