When evaluating an adopted child with uncertain vaccination history, what is the best approach to determine immunity?

• A. Perform antibody titers and reimmunize if needed
• B. Administer boosters without testing
• C. Record the vaccines in EMR
• D. Check vaccine suppliers themselves

Answer: (A)

When a child’s vaccination history is uncertain, you want objective evidence of protection rather than assumptions. Checking specific antibody levels (titers) against vaccine-preventable diseases provides a direct measure of immunity. If the titers are protective, the child is considered immune and does not need additional vaccines. If a titer is nonimmune or indeterminate, you reimmunize according to the recommended catch-up schedule to ensure protection. This approach avoids unnecessary vaccines in those who are already immune and prevents gaps in protection for those who aren’t. Simply giving boosters without testing can over-vaccinate some and still miss immunity in others, and recording vaccines in an EMR or checking vaccine suppliers doesn’t establish the child’s actual immune status.
