All states and some cities have centralized registries of vaccines given by local providers. A registry may not include all ages and may not have all records, but this still can be a great place to check. The Centers for Disease Control and Prevention (CDC) has a listing of registry contacts and websites at www.cdc.gov/vaccines/programs/iis/contacts-locate-records.html.
