Key Findings: V-Safe Text Entry Analysis

  • Three types of free text fields analyzed: SYMPTOMS_DESCRIPTION (SD), HEALTHCARE_VISITS_OTHER (HCVO), and SYSTEMIC_REACTION_OTHER (SRO)
  • Only SD and HCVO fields have a 250-character limit
  • SRO field allows much longer entries with a gradual decline in frequency
  • Current MedDRA coding may miss important information in longer text entries
  • Longer entries often contain additional context like medical history and current medications
