Hi Corrin - Thank you for your message. In response to your question, you will need to complete the medical exam again. However, you may not need to do all of the vaccines if you already received them. Therefore, I recommend trying to obtain proof your vaccination history. Maybe your doctor can provide this document, or you can contact the panel physician for the US Consulate and ask them directly how you can prove your vaccination history. I hope this helps and that all is well. Good luck.
