An 18-Month-Old in Kinship Foster Care With No Immunization Record, Microcytic Anemia, and a Language Delay
An 18-month-old girl was placed with her maternal aunt six weeks ago after a neglect finding, and the aunt brings her for a catch-up visit. The child has moved three times in the past year and no immunization record can be located despite calls to two prior clinics. The aunt reports the toddler eats mostly cereal and drinks roughly 40 oz of whole milk daily. Weight is 9.2 kg (below the 3rd percentile) and length is at the 25th percentile. Capillary hemoglobin is 9.6 g/dL with a low MCV; a capillary lead level is 8 mcg/dL. The child says about four words, does not point to show things, and does not follow a simple command unless it is paired with a gesture. The aunt has physical custody but has not yet received legal guardianship paperwork, and the child is insured through the state foster care program. The clinic has a 30-minute slot and a two-week follow-up opening.
1. Which immunizations would you give at this visit, and how do you reason about the missing record?
Read the worked answer
Treat her as unimmunized. ACIP accepts only written, dated records; a verbal history or a foster placement summary is not sufficient documentation, and serologic testing is not required before restarting a series. Children whose records cannot be located should be vaccinated according to the age-appropriate schedule, and simultaneous administration at separate anatomic sites is both safe and necessary to close the gap.
Today, at 18 months: DTaP #4, IPV #3, Hib (continue or complete the series), PCV per the current schedule, MMR #1 and varicella #1 at separate sites (both live; there is no evidence of immunosuppression here), hepatitis A #1, completion of the 3-dose hepatitis B series, and the seasonal influenza vaccine. Give the first catch-up round now and book the next round in 4 weeks using minimum intervals rather than routine intervals; the accelerated schedule exists for exactly this situation.
Rotavirus is not indicated. The upper age limit for the first dose is 8 months 0 days, so she is too old regardless of how many doses she has missed.
Also today: a TB risk assessment, dental referral, hearing and vision screening, and entry of every dose into the state immunization registry so the next placement can retrieve a record. Do not let the guardianship gap delay vaccination.
2. How do you interpret the hemoglobin and lead results, and what is your next step for each?
Read the worked answer
Both values need one more step before you act on them.
Lead: a capillary level of 8 mcg/dL must be confirmed with a venous sample; capillary results are easily contaminated by lead on the skin. If the venous value is 5-9 mcg/dL, the recommendation is not chelation. It is an environmental history and remediation, iron sufficiency, and a repeat venous level in about 3 months, with repeat testing until the level falls. Chelation is reserved for far higher levels (roughly 45 mcg/dL and above). The immediate task is finding the source: peeling paint in older housing, contaminated soil, imported pottery, cosmetics, or spices, and the aunt's home and any child care setting.
Anemia: a microcytic anemia at 9.6 g/dL in a toddler drinking 40 oz of cow's milk daily is iron deficiency until proven otherwise. Excess milk causes occult gastrointestinal blood loss, displaces iron-rich foods, and increases lead absorption. Order ferritin with CRP, a reticulocyte count, and stool occult blood; start elemental iron 3-6 mg/kg/day and recheck a CBC in 4 weeks. A rise in hemoglobin confirms the diagnosis and justifies continuing iron for 3 months after the value normalizes. Cap milk at 16-24 oz/day and add a pediatric multivitamin with iron.
Keep both problems in a single plan; they interact.
3. The aunt asks whether the child's speech is delayed "because she's been through so much." How do you respond, and what do you set in motion?

Validate the aunt's observation, then decline to attribute the delay to trauma and screen formally. A 4-word vocabulary, no pointing to share interest, and no response to a command without a gesture at 18 months is a communication concern that deserves evaluation, whatever the child's history.
Today: complete the ASQ-3 and the 18-month M-CHAT-R, document a hearing risk assessment, and refer for audiology. Undetected hearing loss and chronic otitis media with effusion are common in children with this history and are treatable causes of language delay; you do not want to attribute to trauma what a hearing aid would fix.
Refer now rather than after the screen returns. Early Intervention (Part C) accepts clinician referrals and, in most states, parent self-referrals; the multidisciplinary evaluation is free and does not require a confirmed diagnosis. Also refer for a developmental-behavioral evaluation for possible autism spectrum disorder, because the wait for that evaluation is often months long.
Say it clearly: screening is not a diagnosis, and the plan is to find out rather than to label. Book a 1-month recheck to review the ASQ and audiology results and to confirm that both referrals were actually completed. Closed-loop follow-up is the step that most often fails for children in placement transitions.
