Vaccination and Titers

Some internationally adopted children may have the vaccination records and some may not. But even those records may not always be reliable. Vaccination titers are used to find out which antibodies a child may already have, rendering them immune to a particular disease.

It is highly recommended that a child should be given a vaccination titer to prevent double vaccinations. Keep in mind that immunity is not permanent, so titers may need to be examined at a later point to ensure that kids are still immune.

Please talk to your healthcare provider about this option before re-vaccinating your child. There are some caveats about titers –  they cannot be used with infants and toddlers and not all states accept a blood titer test as proof of immunity. Please check the National Vaccine Information Center for more information about your state’s requirements.
