immunization-status-checker

Checks patient immunization status against CDC recommended schedules for adults and pediatrics, identifies overdue and upcoming vaccines, flags contraindications based on patient conditions, and generates ImmunizationRecommendation FHIR resources. Use when user asks to "check immunizations", "vaccine status", "what shots are due", "immunization review", "vaccination history", "overdue vaccines", mentions "immunization schedule", "catch-up vaccines", or needs vaccine recommendations. Do NOT use for immunization population reporting across a panel (use patient-panel-overview) or allergy-only queries.
