WHO is now celebrating more than 30 years of freedom from smallpox. What was originally seen as a victory over an ancient scourge can now be viewed as an epidemiologically driven programme to overcome governmental inertia and under-achievement in delivering an off-patent vaccine. Though efforts are accelerating global vaccine use, a plea is made to push the world's governments to commit to universal childhood vaccination via a proposed new programme. The latter should begin by exploiting a long list of ever more affordable off-patent vaccines, vaccines that can virtually eliminate the bulk of the world's current vaccine-preventable disease burden.
世界卫生组织（WHO）如今正在庆祝天花绝迹 30 多年。原本被视为战胜古老瘟疫的胜利，如今可被视为克服政府惰性和未能提供非专利疫苗的流行病学驱动计划。尽管全球疫苗接种工作正在加速，但有人呼吁各国政府通过拟议的新计划承诺为儿童普遍接种疫苗。后者应首先利用一长串越来越实惠的非专利疫苗，这些疫苗几乎可以消除世界上目前由疫苗预防的疾病负担的大部分。
