在大多数经济不发达国家,制订并实行了适用于卫生保健服务的两种相互补充及依存的策略。第一,确定初级卫生保健(PHC)的概念,以建立和保持群众与保健机构间的联系。此种联系是通过对乡村卫生人员的招募、培训、供给及支援等方式而实现的。适当运用这些联系包括通告、对话,并向他们学习,已被证明可以改进卫生保健工作包括提高免疫覆盖率。第二,要使任何规划包括免疫接种取得成功,建立一种支持政府和初级保建人员的,有效的、能坚持的卫生保健服务体系是必不可少的。 In most underdeveloped countries, two complementary and dependent strategies for health services have been developed and implemented. First, to define the concept of primary health care (PHC) to establish and maintain the links between people and health institutions. Such linkages have been achieved through the recruitment, training, supply and support of rural health workers. Appropriate use of these contacts, including announcements, conversations and learning from them, has been shown to improve health care efforts including improving immunization coverage. Second, to succeed in any program, including immunization, it is essential to establish an effective and sustainable health care system that supports government and junior staff.
