Application of attenuated Blue ear Vaccine

Please talk about what you know about the application of blue ear attenuated vaccine-- pay attention to it with you. I suggest not to use it. According to my summary of working in pig farm for nearly 10 years, I don't need to get sick. So no. -- did it have no effect? they say Shanghai Haili is good. We have high fever here, saying that it's okay to inject Shanghai Haili pigs. I don't know if it's true or whether it's advertised by manufacturers-- Shanghai Haili really can-- there are a lot of blue ear strains. It may not be realistic to use vaccines to control the disease. Does the injection of attenuated vaccine help to alleviate the symptoms and reduce the loss of the new strain infection? I agree with the point of view upstairs, but I haven't used it. Reply to Haili daliudian We also use Haley, but we still have high fever-are the symptoms milder? The loss is less?-Shanghai Haili is not bad! And Boehringer! Haley's effect is good, but it's a little expensive-Haley's, hit it and send it.
