An official in charge of the Veterinary Bureau under the ministry said the situation on the Chinese mainland was "stable" as Chinese vaccines were proved to be "safe and effective". So far, no vaccinated pigs had contracted the disease.
The official said some media reports had blamed ineffective vaccination for spread of the disease in Huizhou of Guangdong Province and Sichuan Province, saying Sichuan was even compelled to deliver pigs from neighboring provinces to meet market demand.
