Jonas Salk chose not to patent his 1955 polio vaccine, making it more affordable for the millions of people who needed it.
喬納斯·沙克決定不把他在1955年發明的小兒麻痺疫苗（沙克疫苗）申請專利，使得上百萬有需求的人可以更加負擔得起施打這個疫苗的費用
As a result, he missed out on earning an estimated US$7 billion. Thank you, Dr Salk.
也因為這樣，他錯失了大約70億美元的賺錢機會
感謝你，沙克醫師
