您好，移民局官方对孕期的申请人有特殊的说明，您可以参考：
Q. I am pregnant and do not wish to receive any vaccinations. Do I still have to get them to be able to obtain permanent resident status in the United States?
A. If you are pregnant, the CDC's Technical Instructions direct the civil surgeon how to evaluate the vaccines you are able to receive during pregnancy. If the civil surgeon cannot safely administer a required vaccine, he/she will annotate the Form I-693 by marking the vaccine as contraindicated. See the CDC "Guidelines for Vaccinating Pregnant Women" page for information on pregnancy and vaccinations in general.
一般情况下，医生会给您注射不影响您申请的疫苗，如果是您暂时无法注射的移民，需要医生帮您在体检表格中备注出来。
