Comparative testing of the intensity and the continuity of immunity against swine fever was carried out with pigs producers of serum against edema disease and swine erysipelas, vaccinated with an untreated and a freeze-dried K vaccine. Control infection studies revealed that serum-producing pigs with regard to edema disease, immunized with a freeze-dried and an untreated lapinized K vaccine, could acquire sufficiently stable immunity from the 6th to the 9th month following immunization both in the beginning and at the end of the exploitation period. So far as the intensity and the continuity of immunity of pigs producing serum against erysipelas are concerned the animals were shown to acquire sufficiently stable immunity against swine fever when vaccination was carried out with a freeze-dried K vaccine, while not all of the pigs treated with an untreated K vaccine were protected from swine fever upon control challenging. Therefore, instead of immunization with an untreated K vaccine as many as 400 immunization doses of the freeze-dried K vaccine could be used.
对生产抗水肿病和猪丹毒血清的猪，使用未处理的和冻干的K疫苗进行接种，对比测试其对猪瘟免疫力的强度和持续性。对照感染研究表明，对于生产抗水肿病血清的猪，用冻干的和未处理的兔化K疫苗免疫后，在生产期开始和结束时，从免疫后的第6个月到第9个月都能获得足够稳定的免疫力。就生产抗猪丹毒血清的猪的免疫力强度和持续性而言，当用冻干的K疫苗进行接种时，这些猪表现出对猪瘟获得了足够稳定的免疫力，而用未处理的K疫苗处理的猪在对照攻击后并非都能免受猪瘟感染。因此，可用多达400剂冻干K疫苗来替代未处理的K疫苗进行免疫接种。
