During an initial well-child exam for a recently adopted 3-year-old from Africa with fully vaccinated records, what should the nurse practitioner do?

• A. Administer a booster dose of each vaccine to ensure immunity.
• B. Find out whether the vaccines were provided by reliable suppliers.
• C. Perform antibody titers and reimmunize the child.
• D. Record the vaccines in the child's electronic medical record.

Answer: (C)

You assess actual immune protection by checking antibody levels before deciding on further vaccination when an internationally adopted child has documented vaccination. Antibody titers provide objective evidence of immunity to diseases such as measles, mumps, rubella, varicella, and others, which helps determine whether the child truly needs additional vaccines or can skip them. If the titers show protective immunity, no reimmunization is needed for those diseases, avoiding unnecessary vaccines and potential adverse effects. If titers are nonprotective, you reimmunize according to the catch-up schedule to ensure the child is protected. This approach accounts for possible gaps in records, vaccine storage issues, or waning immunity that could exist despite prior vaccination. Simply administering boosters without evidence of immunity or focusing solely on the reliability of vaccine sources doesn’t directly ensure the child’s protection, and recording vaccines in the chart is important but does not verify immune status.
