Immunity plays a major role in the control of coccidiosis. With the presently practised system of "protected exposure" under chemoprophylactic medication, problems are encountered because of seasonal variation in litter moisture and coccidial challenge. The alternative, "controlled exposure" or "vaccination" products a more solid immunity and more reliable results. This was found to be the method of choice in coccidiosis control in replacement pullets in the semi-arid subtropical climate of Rhodesia.
免疫在球虫病的控制中起着主要作用。在目前采用的化学预防药物下的“保护性暴露”系统中，由于垫料湿度和球虫感染的季节性变化，会遇到一些问题。另一种方法，即“控制性暴露”或“疫苗接种”，能产生更稳固的免疫力和更可靠的结果。在罗德西亚半干旱亚热带气候下，这被发现是后备母鸡球虫病控制的首选方法。
