赴美国、加拿大的留学生(包括中小学生),有时美、加两国不仅需要查验他们的某些检疫传染病的接种证明,同时还要查验他们的“扩大的免疫计划”(EPI)中的各种疫苗接种情况和其它疫苗的接种情况。因此卫生检疫医师应该首先认可他们在国内已接种的疫苗;其次是根据留学者个人的具体情况补齐美国和加拿大当局要求的其它免疫接种,为他们顺利的出国留学提供帮助。 Students from the United States and Canada, including primary and secondary school students, sometimes both the United States and Canada not only need to examine the vaccination certificates of some of their quarantinable infectious diseases, but also examine each of their EPIs Vaccination and vaccination of other vaccines. Therefore, health and quarantine physicians should first recognize their vaccines that have been vaccinated domestically; secondly, supplement other immunizations required by the U.S. and Canadian authorities according to the individual circumstances of overseas students and help them smoothly study abroad.
