Vaccination of cattle and sheep with a combined Clostridium perfringens types C and D toxoid.
Cattle and sheep (30 each) were vaccinated with a combined Clostridium perfringens type C and C perfringens type D toxoid. Vaccination and blood sample collections were made every 2 weeks over a period of 8 weeks. Increases in antitoxin titers occurred after the 2nd administration of the 2.0-ml combined product. Highest titers were recorded when the 2nd vaccinal dose was given 2 weeks after the first. This confirms reports that response to clostridial antigens is greater when the 2nd immunizing dose is delayed 2 to 6 weeks after the initial dose.
