NEW VERSION: The application is intended for use by the general public as a tool for tracking vaccination schedules. The application allows the user to add or edit family member profiles, provides an interactive vaccination timeline for adding vaccination appointments and recording completed vaccinations, a child’s game, and country-specific vaccination schedules. It allows users to track family member’s vaccination details in one place and is intended to be used in conjunction with the counsel of their healthcare provider (HCP). It is not intended to replace an HCP’s medical judgment and responsibility.
