To gather information about your vaccination status, talk to your parents or other caregivers. Check with your health care provider's office. If necessary, you may check with previous health care organizations where you received care. Or check with your schools or employers who required vaccinations. You could also contact your state health department to see if it has a registry that includes adult immunizations.
If you can't find your records, your health care provider might be able to do blood tests to see if you are immune to certain diseases that can be prevented by vaccines. You might need to get some vaccines again.
