First thing with regard to vaccinations get an immunisation report from your doctor to check what is recorded in your medical records.
Unfortunately, my doctor had no record of my ever having had any childhood vaccinations.
I was directed to have MMR, Tdap, Hepatitis B and varicella. The last one is waived if you have had a chickenpox. A number of other vaccines were deemed not to be age appropriate for me.
As @OldUser says once you have your immunisation record contact the panel physician. They often offer you missing vaccines on the day of your appointment, but that will probably be more expensive than getting them from your own doctor.
