EU drug agency urges approval for dengue vaccine
Europe’s drug regulator has recommended approving the first vaccine for dengue fever, despite concerns about the vaccine’s wide use and a lawsuit in the Philippines alleging that it was linked to three deaths.
The European Medicines Agency said on Friday it had adopted a “positive opinion” of French pharmaceutical company Sanofi’s Dengvaxia. The vaccine is the world’s first against dengue, which sickens about 96 million people annually.
The mosquito-spread virus is found in tropical and sub-tropical climates across Latin and South America, Asia, Africa and elsewhere. It produces a flu-like disease that can cause joint pain, nausea, vomiting and a rash. In severe cases, dengue can result in breathing problems, hemorrhaging and organ failure.
There is no specific treatment for dengue and there are no other licensed
vaccines on the market.
This year, the World Health Organization said the vaccine needed to be dealt with “in a much safer way” and should be given mainly to people who had dengue before. The vaccine is licensed for use in about 20 countries.
The UN health agency said there were “significant obstacles” in using the vaccine and that a rapid test should be developed to determine if people had previously been infected with dengue.
Sanofi previously warned that people who had never been sickened by dengue were at risk of more serious disease after receiving the vaccine. The company said it expected to take a 100 million-euro (about $150 million Cdn) loss based on that news.
The Philippines was the first country to introduce a national dengue immunization program, which it halted after Sanofi’s announcement last year.
