Flashermac Posted July 11, 2014 Report Share Posted July 11, 2014 PARIS - A prototype vaccine for dengue that two years ago yielded lukewarm results has proved more effective after wider trials and is a potential arm against the disease, researchers said Friday. Devised by the French pharmaceutical giant Sanofi Pasteur, the so-called CYD-TDV vaccine provided only 30 percent protection against the dangerous fever when first tested among children in Thailand. Widened to trials in four other Asian countries, where disease conditions vary greatly, the vaccine’s protection has been shown to be significantly higher, at 56.5 percent overall, the scientists said. The result falls short of the benchmark set by classic vaccines such as those for polio and measles, which can be more than 99 percent effective. One reason for this is that CYD-TDV performed poorly against one of the four strains of dengue virus, the investigators reported in The Lancet. These strains, or serotypes, circulate simultaneously, which means a vaccine should ideally protect against all of them. Even so, the prototype was safe and well tolerated and its shield, if only partial, means it should be enlisted in the fight against dengue, they argued. "Our results suggest that vaccination with CYD-TDV can reduce the incidence of symptomatic dengue infection by more than half and importantly reduced severe disease and hospitalisations," said Maria Rosario Capeding from the Philippines’ Research Institute for Tropical Medicine. "This candidate vaccine has the potential to have a significant impact on public health in view of the high disease burden in endemic countries." Dengue is a potentially fatal fever, caused by a virus transmitted by a mosquito when it takes its blood meal, and is especially dangerous for children.

phuketfan300 Posted October 6, 2014 Report Share Posted October 6, 2014 Yes, definitely sounds promising! With its availability next year, we all hope that this advancement will also take place in finding a cure for Ebola. Link to comment Share on other sites More sharing options...
