A study was carried out in Argentina with 5 groups of 24 heifers each. Four groups were vaccinated (B, C, D and E) twice (20 days apart), while group A was used as control (unvaccinated). Half of each group was revaccinated after 104 days. Blood samples were collected after 0, 20, 48, 76, 104, 132, 160 and 188 days and tested for antibodies against C. chauvoei.
