The civil surgeon should complete everything before giving you the medical exam results. Get the shots, complete the medical and send everything in together. If you submit the package without the medical you risk having your paperwork rejected. If it is not rejected you should not submit the medical unless USCIS requests it (otherwise they will lose it) or you can bring it to your interview. Best though is to submit everything together. If you have any other questions you can reach me thru my website below. Good luck!
