During the anamnestic response, the sera of four rabbits immunized with a polyvalent pneumococcal vaccine contained large amounts of cryoglobulins belonging to the G and M immunoglobulin classes. These cryoglobulins appeared to possess antibody activity since they agglutinated a suspension of the pneumococci that was used for immunization.
在回忆反应期间，用多价肺炎球菌疫苗免疫的4只兔子的血清中含有大量属于G和M免疫球蛋白类别的冷球蛋白。这些冷球蛋白似乎具有抗体活性，因为它们使用于免疫的肺炎球菌悬液发生凝集。
