Sanofi’s experimental vaccine against dengue protected children with all four types of the mosquito-borne illness in a clinical test, a stronger result than shown in a smaller study this year.
In a trial of almost 21,000 children in Latin America and the Caribbean, the shot reduced the risk of infection by 60.8 percent, the Paris-based company said in a statement today. The vaccine also led to an 80.3 percent drop in the risk of hospitalizations.
