Stop Dengvaxia vaccinations now

The advisory issued this week by global vaccines leader Sanofi Pasteur against using its own dengue vaccine, Dengvaxia, on people who have had no prior infection only confirms what some health officials and advocates have been warning us about all along.

Sanofi Pasteur informed the Philippine Department of Health (DoH) on Wednesday that new analysis of clinical data gathered over a six-year period showed that while Dengvaxia helped patients infected in the last 30 months, those who have had no prior infection may in the long term be at risk of contracting a more severe case of dengue.
