This program mandates vaccination for female cattle and buffalo between 3 and 8 months of age using B19 or RB51 vaccines. Regulations require specific diagnostic testing, isolation, and slaughter of positive animals within 30 days, with all vaccinations performed by registered veterinarians. In the Distrito Federal, the Secretariat of Agriculture, Supply, and Rural Development (Seagri-DF) has reinforced deadlines for the 2026 vaccination campaign. Beef and buffalo producers must complete vaccinations for females aged 3 to 8 months by December 31, 2026. Producers are also required to submit vaccination certificates and purchase invoices to the Seagri-DF Agricultural Defense department by this date to verify compliance. The RB51 vaccine remains an alternative option and is indicated for females older than eight months. ## Timeline ### 2026-10-30: Distrito Federal reinforces brucellosis vaccination deadline Producers in the Distrito Federal must vaccinate female cattle and buffalo against brucellosis and submit documentation by December 31, 2026, to ensure livestock and public health safety. 2 sources. https://clstr.news/cluster/distrito-federal-reinforces-brucellosis-vaccination-deadline ### 2026-10-19: Bovine brucellosis regulations and vaccination mandates in Brazil Brazil's PNCEBT mandates bovine brucellosis vaccination for females aged 3 to 8 months and requires strict testing and slaughter protocols for positive cases to manage this zoonotic disease. 2 sources. https://clstr.news/cluster/bovine-brucellosis-regulations-and-vaccination-mandates-in-brazil --- Cite as: Bovine brucellosis control in Brazil.
