- Brazil suspends its dengue vaccine as a precaution after two deaths
Brazil temporarily suspended its dengue vaccination campaign after detecting two deaths and serious adverse reactions. The single-dose vaccine, developed by the Butantan Institute in São Paulo, had been administered to half a million people. Health authorities stated there is insufficient data to link the deaths to the vaccine and emphasized the suspension is a preventive measure.
