For an adult, only the medically necessary shots will be given, and these are usually the TD/TDAP and MMR shots, (plus the flu shot, if the medical exam is done during the flu season). Then there's also the Man2/Mantoux TB skin test used in testing for TB. There will be some blood work done too.
You guys can save yourselves a bunch of $$$ (if you can't find a civil surgeon that will bill your medical insurance directly) by visiting your local health department, the shots are quite cheap from them. It's also possible to get the shots cheaply from places like Walmart, CVS, RiteAid, etc. Just make sure you get a record of all the work that's done, then visit a civil surgeon and have them do the blood work and transfer the medical records to your I-693.
CAUTION: Before doing the TB skin test at your local health department, be sure to have found the CS that you'll be using to transfer the medical records to your form and confirm from them if they're ok with you bringing in a TB skin test result from the medical health department. If they're not willing to do that, then leave out the TB test and get the rest of the shots, the CS can them perform the TB test in their office.
