Linda Tikofsky, Boehringer-Ingelheim DVM, provides sound reasoning for a two-in-one effect when vaccinating dry cows. This is sound advice for producers and a good reminder for dairy veterinary teams and the animal health pros who service dairies.
A lactating cow vaccination protocol should begin at least 30 days prior to breeding, Tikofsky says. By vaccinating cows during the dry period against some of the common disease challenges they may face, they’re more likely to enter their next lactation period with a robust immune response to fight off common infections.

Failure of passive transfer, when a calf doesn’t receive enough high-quality colostral antibodies, has both short- and long-term impacts. Immediately, that calf does not have protection against the common viral and bacterial infections that are in its environment. With failure of passive transfer, calves are also more likely to develop scours or pneumonia and are at greater risk of death.
