[目的]确保强化免疫各级所供应使用的疫苗有效,评价福建省冷链系统运转状况。[方法]从省→设区市→县→乡级规范化接种点(临时接种点),对麻疹疫苗进行跟踪抽样主动监测,同时选择3条疫苗运输线(闽东、闽西和闽南),检测比较各环节供应和使用的疫苗效价,评价冷链运转效果。[结果]抽检74份麻疹疫苗样品,100%达到出厂合格滴度(≥3.5 logTCID50/ml),运输线上各环节供应和使用的疫苗滴度均值均在3.5 logTCID50/ml以上。[结论]本次强化免疫工作供应使用的麻疹疫苗效价有保证,冷链系统运转正常。
[Objective] To ensure that vaccines supplied at all levels of intensified immunity are effective and evaluate the operation status of cold chain system in Fujian Province. [Method] The measles vaccine was monitored by follow-up sampling from the standardized vaccination sites (temporary inoculation points) of province → municipalities → county → township level. Three vaccine transport routes (Fujian, Fujian and Fujian) Compare the supply and use of vaccines in various aspects of potency, evaluation of cold chain operation. [Results] The samples of 74 measles vaccines were sampled and 100% reached the qualified titers (≥3.5 logTCID50 / ml). The mean titers of vaccines supplied and used in all aspects of the transportation line were above 3.5 logTCID50 / ml. [Conclusion] The titer of measles vaccine supplied by this intensive immunization work is guaranteed, and the cold chain system is in normal operation.
