More info is needed as far as your timing of the first dose of vaccine. I would booster with the same family of vaccine. I would still suspect Myco even if the test was negative. I have seen good results giving first dose of vista once sq along with Myco-B one dose two weeks before weaning and then booster with Bovilis Vista at weaning.
