Healthcare workers in Pernambuco vaccinated against dengue with the Butantan vaccine in the last 21 days should undergo monitoring at health units for possible adverse reactions. The guidance was issued by the Pernambuco State Health Department (SES-PE) on Monday (9th), after the Ministry of Health temporarily suspended vaccination of this population nationwide.

"A Secretaria Estadual de Saúde de Pernambuco (SES-PE) orientou que profissionais de saúde que se vacinaram contra a dengue, nos últimos 21 dias, com o imunizante produzido pelo Instituto Butantan, realizem acompanhamento em unidades de saúde para monitoramento de possíveis reações adversas."

The measure affects Primary Health Care workers aged 15 to 59 who were participating in the immunization strategy started in February. In Pernambuco, 11,711 doses have already been administered and recorded in the National Health Data Network (RNDS). SES-PE also instructed municipalities to remove remaining doses from units and store them in municipal cold chains pending new guidance from the Ministry of Health.

"A medida afeta trabalhadores da Atenção Primária à Saúde com idade entre 15 e 59 anos que participavam da estratégia de imunização iniciada em fevereiro deste ano. Em Pernambuco, 11.711 doses já foram aplicadas e registradas na Rede Nacional de Dados em Saúde (RNDS)."

Vaccinated professionals should watch for symptoms such as fever, intense abdominal pain, persistent vomiting, bleeding, dizziness, excessive drowsiness, signs of dehydration or general deterioration for three weeks after application. If symptoms occur, the guidance is to seek medical attention immediately. Pernambuco's Immunization Superintendent, Magda Costa, emphasized that cases will be monitored by municipal surveillance teams.

"os profissionais vacinados recentemente devem observar seu estado de saúde durante três semanas após a aplicação da dose. Em caso de sintomas como febre, dor abdominal intensa, vômitos persistentes, sangramentos, tontura, sonolência excessiva, sinais de desidratação ou piora do estado geral, a orientação é procurar atendimento médico imediatamente."

The national suspension was adopted after recording 3,703 notifications of unexpected events with dengue-like symptoms between January and May — 0.7% of all immunized people. Of this total, 42 cases showed alarm signs and three were classified as severe, including two deaths under investigation. Vaccination of children and adolescents aged 10 to 14 was not affected, as it uses a vaccine from another manufacturer.
