The Health Ministry temporarily suspended vaccination with the Butantan Institute's vaccine after recording 42 cases of serious adverse reactions, including three severe cases and two deaths under investigation.
The preventive suspension was announced on Monday (8/6) and takes effect from Tuesday (9/6). About 500,000 doses have already been administered nationwide, prioritizing primary health care professionals. The cases under investigation involved a 39-year-old woman who developed severe dengue and was discharged, plus two deaths: a 48-year-old woman with neurological involvement and a 58-year-old man with refractory shock. All were health professionals. Minister Alexandre Padilha stated that no causal link between the vaccine and the events has been proven yet. People vaccinated in the last 21 days should seek health units if they show symptoms such as fever, intense abdominal pain or bleeding. The Federal District administered about 4,050 of the 6,320 doses received. The measure does not affect the Takeda vaccine used in children and adolescents.
