在大规模免疫运动失败后，通过生存和遏制接种实现了天花的根除。本文分析了这一失败的原因。对印度次大陆和非洲人口密度的比较表明，在人口稠密的地区，即使80%的疫苗覆盖率也会留下足够高的易感人群密度，足以维持这种疾病，这一发现对其他疫苗活动具有重要意义。
The eradication of smallpox was achieved by surviellance and containment vaccination after the failure of mass immunization campaigns. The reasons for this failure are considered in this paper. Comparison of population densities in the Indian subcontinent and Africa show that in highly populated areas even an 80% vaccine coverage will still leave a density of susceptibles high enough to maintain the disease, a finding with important implications for other vaccine campaigns.
