[QUOTE="Lucky_P, post: 789133, member: 12607"] Use one of the MLV intranasals - they do a better job of preventing respiratory disease than the injectibles, anyway . Fewer adverse reactions with TSV-2 than Nasalgen, and the new Inforce 3 from Pfizer also contains BRSV; we're using it this fall. You'll probably get minimal to no detectable IBR serum titer with the intranasals (titers don't really give any reliable measurement of 'protection', anyway) - but you should get good protection against respiratory infection. Straying a bit from the original question, as I can't really comment on how quickly IBR titers will drop... Injectible MLV vaccines 'block' effective immune response to bacterins(clostridials, Pasteurella/Mannheimia, etc.) given at the same time, but the intranasals don't. So... if you're giving bacterins at the same time you're using a MLV, it's better to give the bacterin with an intranasal, and then, if you need to booster with a MLV IBR/BVD - for reproductive protection - use one of the injectible MLV vaccines as a booster 10-14 days later.
