Sanofi and its vaccines global business unit Sanofi Pasteur, recently announce that the Strategic Advisory Group of Experts on Immunization (SAGE) has issued its recommendations to the WHO on the use of Dengvaxia® dengue vaccine. The SAGE advises that countries with high dengue transmission consider introduction of the dengue vaccine as part of an integrated disease prevention strategy including vector control to effectively lower their dengue disease burden. Successful introduction of dengue immunization alongside other prevention efforts should help endemic countries to achieve the WHO objectives to reduce dengue morbidity by 25% and mortality by 50% by 2020.
“We welcome these recommendations for Dengvaxia® from SAGE, the advisory group to the WHO, for vaccines and immunization.” said Elias Zerhouni, MD, President of global R&D, Sanofi. “Dengvaxia® has been approved in four countries already, including Mexico and Brazil, which have regulatory authorities recognized by the WHO. These WHO SAGE recommendations further validate the scientific and medical value of Dengvaxia® and send a clear message to endemic countries about the strong public health benefit to be gained by introducing the dengue vaccine in integrated disease management efforts to combat their dengue burden.”
Dengvaxia® vaccine’s anticipated impact on dengue fever disease burden is expected to stem from the vaccine’s proven ability to prevent 8 out of 10 dengue hospitalizations and up to 93% of severe dengue cases–including dengue hemorrhagic fever–in study participants 9 years and older, as demonstrated during 25 months of follow-up of phase III efficacy studies.
The recommendations from the SAGE are based on the technical review of clinical data from 25 clinical studies conducted in 15 different endemic and non-endemic countries around the world, including more than 40,000 study participants.
As of March 2016, Dengvaxia® was licensed in Mexico, the Philippines, Brazil and El Salvador for prevention of dengue from all four serotypes in individuals 9-45 years of age living in endemic areas. Regulatory review processes for Dengvaxia® are continuing in other countries where dengue is a public-health priority. Both public and private vaccinations have already begun in the Philippines and discussions are underway in the other approval countries for launches later this year.
Sanofi Pasteur’s vaccine is the culmination of over two decades of scientific innovation and collaboration, as well as 25 clinical studies in 15 countries around the world. Over 40,000 volunteers participated in the Sanofi Pasteur dengue vaccine development program (phase I, II and III), with 29,000 volunteers receiving the vaccine. Large-scale efficacy studies of Dengvaxia®, including 25-month follow up, were successfully completed in 2014.
Dengvaxia® is the first vaccine in the world licensed for the prevention of dengue fever. The vaccine is produced in a dedicated production site in France, with a full-scale production capacity of 100 million vaccine doses annually.
