There are several ways to check on our history of immunizations, the first choice being to ask our family doctor for a record. For those of who do not have a family doctor, there are other ways to track down our vaccination records, including: • Ask parents or caregivers for childhood immunizations • Check with previous employers that required vaccinations • Check with your public health clinic • Contact your state’s health department If the vaccination record cannot be found, the official recommendation from the CDC (Centers for Disease Control and Prevention) is to receive the full course of recommended vaccines. There are no associated risks of side effects of receiving the same vaccination twice, aside from the discomfort of getting extra injections.
