Someone I know is about to immigrate to the US, and was told to be prepared to receive a buttload of "required" vaccines in order to do so.
I was asked to look this up in English to see the particulars of the requirements.
I found that that the U.S. Citizenship and Immigration Services website has a Vaccine Requirements page.
Toward the bottom of this page under the Questions and Answers section there's this one:
You just have to tell the civil surgeon you don't want them, and can fill out a waiver for religious or moral beliefs.
On Form I-693,which is the medical examination and vaccination record that the civil surgeon has to fill out for your aplication, there's a bubble for him/her to check off that says:
Applicant will request an individual waiver based on religious or moral convictions
