Brazil has approved the world’s first single-dose dengue vaccine, marking a historic milestone as dengue cases rise globally amid climate change. The vaccination, known as Butantan-DV, was developed by the Butantan Institute in São Paulo and authorized by Brazil’s health regulatory agency ANVISA for people aged 12 to 59. Unlike the current vaccine TAK-003, which requires two doses three months apart, Butantan-DV’s single dose allows for quicker, easier vaccination efforts.
