计划免疫——冷链运转包括疫苗冷藏、冷运和免疫接种实施两部分内容。冷链装备的完善并正常运转,无疑对推动计划免疫的开展,提高免疫接种质量起了重要保证作用。然而,计免——冷链运转需要经费支持,如何在保证达到接种率指标的前提下,减少计免——冷链运转次数,利用季节温度特点减少运转中疫苗冷运次数,对于降低计划免疫总的 Planned immunization - cold-chain operation includes the two parts of the vaccine cold storage, cold-shipped and immunization. The perfect and normal operation of cold chain equipment undoubtedly plays an important role in promoting the planned immunization and improving the immunization quality. However, under the premise of ensuring that the vaccination rate index is reached, the number of free-cold chain runs is reduced, and the seasonal temperature characteristics are utilized to reduce the number of cold-blooded vaccines in operation. This is not the case for reducing planned immunization Total
