摘要
世衛組織估計全球生產的疫苗有一半無法送達需要的人群，主要原因是疫苗在使用前失去效力。大多數疫苗必須全程冷藏保存。本文探討免冷藏疫苗是否能轉變全球免疫接種方式。
詳細內容
The World Health Organization (WHO) estimates that half of all vaccines produced worldwide never reach the people who need them. The reason? They lose their effectiveness before they can be used. Most vaccines must be kept cold from the moment they are manufactured until they are administered.
