Brazil suspends dengue vaccine following two deaths

Brazil said Monday it was temporarily suspending use of the world's first single-dose dengue vaccine following two suspicious deaths. More than half a million people have received doses of the vaccine this year, which was developed publicly in Brazil and approved by health authorities in November.

Forty-two people meanwhile had "more severe reactions," according to the health ministry. Authorities have recorded three severe cases, including two that resulted in the deaths of a 58-year-old man and a 48-year-old woman. The minister said the "absolutely unexpected" effects had not been observed during tests on over 16,000 volunteers across 14 Brazilian states.
