What is langcare-immunization-status?

A vaccination-status checker that compares a patient's recorded immunizations with current CDC and ACIP recommendations. CDC and ACIP are United States public-health bodies that publish vaccine guidance.

It helps clinicians review vaccine histories, identify missing doses, and prepare recommendations for a patient's care.

It shows which vaccines are complete, due, overdue, or potentially unsuitable based on the patient's age, health risks, and allergies.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00063	$0.00685
Opus 5.5	$0.00025	$0.00274
Sonnet 5.5	$0.00013	$0.00137
Haiku 4.5	$0.00006	$0.00068

Security

Grade A, and why

langcare-immunization-status scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Immunization Status Checker

When to Use This Skill

Use when a clinician needs to evaluate a patient's vaccination history against current CDC/ACIP recommendations and identify gaps.

Clinical Workflow

Use fhir_read to retrieve Patient demographics (age, gender for age-based schedule)
Use fhir_search to pull all Immunization resources (status=completed)
Use fhir_search to pull active Condition resources for risk-based vaccine recommendations (immunocompromised, asplenia, pregnancy, chronic conditions)
Map completed immunizations against CDC/ACIP schedule (see references/cdc-schedule.md) by age group and risk factors
Identify: completed (up to date), due now (within recommended window), overdue (past recommended date), contraindicated (based on conditions/allergies)
Present immunization status checklist with specific vaccine recommendations

FHIR Resources

Patient -- Age for schedule determination
Immunization -- Vaccination history: vaccineCode (CVX), occurrenceDateTime, status, doseNumberPositiveInt
Condition -- Risk factors for additional vaccine recommendations
AllergyIntolerance -- Vaccine contraindications (egg allergy, gelatin, neomycin)

FHIR Query Examples

Pull Immunization History

fhir_search(resourceType="Immunization", queryParams="patient=[patient-id]&status=completed")

Pull Risk Conditions

fhir_search(resourceType="Condition", queryParams="patient=[patient-id]&clinical-status=active")

Clinical Guidelines

CDC/ACIP Recommended Immunization Schedules (updated annually)
CDC catch-up immunization schedule
ACOG recommendations for immunizations in pregnancy

Interpretation Guide

Organize by vaccine: name, series status (dose X of Y completed), date of last dose, next dose due, status (current/due/overdue/contraindicated)
Age-specific schedule: childhood (0-18), adult (19-64), older adult (65+)
Risk-based additions: pneumococcal (PCV20 or PCV15+PPSV23) for age 65+ or immunocompromised, hepatitis A/B for risk factors, meningococcal for asplenia
Pregnancy-specific: Tdap each pregnancy 27-36 weeks, flu in flu season, avoid live vaccines (MMR, varicella)
Flag high-priority gaps: no flu vaccine in season, no COVID primary series, no Tdap in 10+ years

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
