在一个地方性黄热病地区进行的实地研究表明，在大规模接种17 D型疫苗9年后，接种疫苗的人具有很高的免疫力。因此，这种保护似乎非常成功，接种疫苗后签发的黄热病证书的有效期应延长至9年，前提是最初的疫苗接种是针对7岁以上的个人。在这个年龄以下的儿童中接种疫苗的持久效果尚未得到明确证明。
Field studies in a region of endemic yellow fever, after a lapse of 9 years since mass vaccination with type 17 D vaccine, show a very high degree of immunity among those so vaccinated. It seems therefore that the protection is highly successful and that the validity of yellow fever certificates issued after such vaccination should be extended to 9 years, provided the original vaccination was given to individuals over 7 years of age. The lasting effects of vaccination among children under that age are not as yet definitely proved.
