比尔·盖茨：我们比以往任何时候都更加接近于将脊髓灰质炎（脊灰）彻底消灭。根据最新的数据，去年全球新增脊灰病例数创历史最低——仅仅21例。这简直不可思议，尤其当你想到只是30年前，全球每年还有35万人感染脊灰。

这一成就的取得，要归功于数百万疫苗接种员，他们挨家挨户为超过25亿儿童接种了疫苗。多亏了这些英雄的努力，1600万原本会因脊灰而瘫痪的人，现如今能够正常地行走。然而革命尚未成功。少量仅存的脊灰病例还在三个国家出现：阿富汗、巴基斯坦和尼日利亚。

这些国家里的许多接种员继续着在艰难、危险条件下的工作，保护孩子们远离这种令人瘫痪的疾病。他们值得我们所有人感谢和支持。让我们一起迎接不再有孩子会受到脊灰威胁那一天。

On the doorstep of victory

The world is closer than ever before to wiping out polio. Last year, the world saw the fewest number of polio cases—just 21, according to the latest figures. That’s incredible, especially when you consider that just 30 years ago, there were 350,000 cases of polio per year worldwide. 

The heroes who have made this progress possible are the millions of vaccinators who have gone door to door to immunize more than 2.5 billion children. Thanks to their work 16 million people who would have been paralyzed are walking today. But the job is not over. The few polio cases left can be found in three countries: Afghanistan, Pakistan, and Nigeria. Many of the vaccinators in these countries continue to work in difficult and dangerous conditions to protect children from this paralyzing disease. They deserve our thanks and support as we work toward the day when no child is at risk of polio.
