Laws of Immunological Common Sense At the 2021 Recent Veterinary Graduate Conference, Dr. Chris Chase discussed immunology and vaccination. He summed up laws of... immunological common sense for cows and calves. His observations are that in general, we vaccinate cows and calves too much and too soon. On a primary vaccine, if we see nothing, nothing happened, and we probably did not turn on innate immunity due to underlying issues, he said. He also commented that the interval for boosting needs to be 21 days or longer, and the length depends on the vaccine. Common Sense for Calves Passive antibodies (colostrum) are protective Better the colostrum management, the less need to vaccinate Intranasal vaccines in young calves, especially for BRSV, are important, if BRSV is a problem Vaccinate before shipping OR Vaccinate at least a few days after shipping -- a week or two later is best Common Sense for Cows Vaccination of dams 4-6 weeks prior to calving improves colostral antibodies Vaccination of pregnant cows have two targets, the calf and the cow Vaccination of the post-partum beef cow wait at least 3 -4 weeks after calving Vaccination of the post-partum dairy cow wait until 30-45 days in milk Chase suggests to avoid turning on pro-inflammatory responses during times of stress which include vaccination, parturition, weaning and surgery.
