title: Immune responses of dairy cattle to parainfluenza-3 virus in intranasal infectious bovine rhinotracheitis-parainfluenza-3 virus vaccines.
abstract: Two hundred and fifty dairy heifers were vaccinated at three to six months of age with an intranasal infectious bovine rhinotracheitis-parainfluenza-3 vaccine. Eighteen additional heifers were tested prior to vaccination and again three to four weeks after vaccination. Neither cell-mediated nor humoral immunity was significantly raised to parainfluenza-3 virus in either group of cattle.
