Rules Based on Patient's Age

• If a patient is >= 19 years and did NOT complete the series before 19 years of age, then the Recommendation is Conditional and the reason code is HIGH_RISK.⁶
  
• Shots administered to a patient who is >= 19 years and < 22 years of age will continue to be evaluated (based on minimum intervals) and, if valid, will count toward completion of the series.
• If a patient's age at administration is >= 22 years and the patient did NOT complete the series before 22 years of age, then the Evaluation is Accepted and the reason code is ABOVE_REC_AGE_SERIES. (Shots administered to a patient >= 22 years of age do NOT count toward completion of the series; the series can NOT be completed once the patient is >= 22 years old.)
