<p>Bivalent live vaccine for prophylaxis of fowl Marek's disease and a process for its preparation are disclosed. The vaccine is stored in an ampule in a lyophilized state wherein both turkey herpes virus (HVT) FC-126 strain effective as a vaccine for fowl Marek's disease and Marek's disease virus (MDV) SB-1 strain are present. This vaccine can be easily used by merely diluting the contents of the ampule. This bivalent vaccine can be prepared by culturing respective viruses separately in two steps using fowl embryo cells while controlling initiation of the cultures so that the two cultures are completed at the same time, mixing the obtained two virus culture liquors with each other, pouring it into ampules, sealing and lyophilizing it.</p> |
