Write it like you would a legal document. Look at the law and use that langugage to request they acknowledge your exemption and provide acommodation. Here's a succinct summary of Title VII: >Title VII requires federal agencies, upon notice of a request, to reasonably accommodate employees whose sincerely held religious beliefs, practices or observances conflict with work requirements, unless the accommodation would create an undue hardship. In other words they **must** acommodate your sincerely held religious belief. The only way they can deny your acommodation is if it places an undue burden on the employer. We write our request using the language of Title VII. "Title VII exempts me from receiving the vaccine due to my sincerely held religious beliefs. As a reasonable acommodation I request that you waive the vaccine requirement. Thank you." It's that simple. Though be prepared for your employer to push back. If the reasons for vaccines is to prevent the spread of covid, you might want to offer them something you would be willing to do instead of getting the vaccine. It's a negotiation. How hard you want to push is up to you and depends on your individual circumstances. And if they inquire about your religion, remember that the only valid reason for them to do so is to figure out how to acommodate you. Always bring the discussion back to that point.
