Carried out from May this year, the reduced dosage would be for the first stage of vaccination for cattle and carried out across the majority of Brazilian states.
The dosage change is part of the National Program for the Eradication and Prevention of Foot-and-Mouth Disease, which aims to totally withdraw vaccination in the country by 2021.
Brazil’s department of animal health’s veterinary epidemiologist Diego Viali dos Santos said the reduction of dosage would decrease reactions in animals, such as lumps or swelling.
“Producing laboratories have sufficient stock of the new product to meet the demand of breeders,” said Viali dos Santos.
The dose will only be applied to young animals up to 24 months of age in Acre, Espírito Santo and Paraná.
Brazil was officially declared free from foot-and-mouth disease with vaccination last year, after being listed by the World Organization for Animal Health (OIE).
However, the disease has caused problems for the likes of South Africa earlier this year, with its red meat industry reporting “serious losses” and imposing a ban on imports from neighbouring countries.
