In a village with a population of more than 2,000, with measles outbreaks in alternate years, annual single-day measles immunization campaigns were conducted during four winter seasons. Measles vaccine was offered to children 1 year of age and older, with no previous measles or immunization. There has been no outbreak of measles since the introduction of immunization to date. Four cases of introduced measles did not result in any secondary case. This vaccine delivery strategy (annual pulse immunization), designed to improve coverage and simplify cold chain management, was shown to be suitable for the control of measles in rural communities in the Third World.
在一个有2000多人的村庄，麻疹疫情隔年爆发，在四个冬季开展了年度单日麻疹免疫活动。为1岁及以上未曾患过麻疹或未曾接种过疫苗的儿童提供麻疹疫苗。自引入免疫措施以来，未曾爆发过麻疹。4例输入性麻疹病例未导致任何二代病例。这种旨在提高覆盖率和简化冷链管理的疫苗接种策略（年度强化免疫）被证明适用于第三世界农村社区的麻疹控制。
