[QUOTE="Lucky_P, post: 1093589, member: 12607"] Thanks for that link. Have been trying to get this information out since I first saw it reported, several years ago. Pretty likely that many producers - and probably a significant number of veterinary practitioners, as well - are unaware of these interactions, and are not getting adequate protection from the relatively expensive vaccines they're using - not to mention time and effort handling the animals - all because they're unaware of the function and interactions of the immune system. The interference by systemic (injectible) mlv vaccines on response to bacterins extends beyond just the Pasteurella/Mannheimia products - may well also interfere with response to the Clostridial bacterin/toxoids, and possibly to response to Lepto vaccines. Recent (within the past 6 months) presentation by Dr. Vic Cortese indicated that the folks at Zoetis have worked out antigen loads, etc., sufficiently for their new combo BoviShield/One Shot to be able to overcome potential interactions and elicit an appropriate immune response to all components.
