FDA Approves Faulty Dengue Vaccine that Harmed 100,000 Children in the Philippines, Killing Some, and Prompted Lawsuits
The U.S. Food and Drug Administration just approved one of the most sought after vaccines in recent decades. It’s the world’s first vaccine to prevent dengue fever — a disease so painful that its nickname is “breakbone fever.”
The vaccine, called Dengvaxia, is aimed at helping children in Puerto Rico and other U.S. territories where dengue is a problem.
But this vaccine has a dark — and deadly — history. One that has led to criminal charges in the Philippines, and sparked national panic.
[E]stimates are that more than 100,000 Philippine children received a vaccine that health officials say increased their risk of a severe and sometimes deadly condition. In addition, other children who received the vaccine may have been endangered because, their parents alleged, they were not in good health.
The French pharmaceutical company Sanofi Pasteur spent 20 years — and about $2 billion — to develop Dengvaxia. The company tested it in several large trials with more than 30,000 kids globally and published the results in the prestigious New England Journal of Medicine.
But halfway around the world from the Philippines, in a Washington, D.C., suburb, one scientist was worried about the new vaccine.
“When I read the New England Journal article, I almost fell out of my chair,” says Dr. Scott Halstead, who has studied dengue for more than 50 years with the U.S. military.
When Halstead looked at the vaccine’s safety data in the clinical trial, he knew right away there was a problem.
For some children, the vaccine didn’t seem to work. In fact, Halstead says, it appeared to be harmful. When those kids caught dengue after being vaccinated, the vaccine appeared to worsen the disease in some instances. Specifically, for children who had never been exposed to dengue, the vaccine seemed to increase the risk of a deadly complication called plasma leakage syndrome, in which blood vessels start to leak the yellow fluid of the blood.
