The World Health Organization says that the first-ever vaccine for dengue needs to be dealt with in “a much safer way.” It said the shot should mostly be given to people who have previously been infected with the disease. In November, the vaccine’s manufacturer, Sanofi Pasteur, said that people who had never been sickened by dengue before were at risk of developing more serious disease after getting the shot.
