Brazil suspends its dengue vaccine as a precaution after two deaths

Brazil temporarily suspended the dengue vaccination campaign it began in January, after detecting two deaths and several cases of serious adverse reactions. The vaccine, the world's first single-dose shot, was developed by the Butantan Institute in São Paulo and had already been given to half a million people through the public health system. Health authorities stressed that there is not yet enough data to link the deaths to the product and that the interruption is a preventive measure.
