Dec 1, 2025December 2025 — ImpulsoPrevine: Focused on data accuracy and reliability in HPV vaccination status reporting. Delivered a critical bug fix to the HPV vaccination status calculation logic to ensure accurate status reporting based on age and vaccination date. Added an automated test to cover the edge case where a patient turns 15 on the PEC export date, validating the corrected behavior. This release improves data integrity, export reliability, and downstream analytics. No new features released this month beyond the bug fix; emphasis was on quality and stability.
