Vaccination Schedule Calculator
Digital continuity tool for tracking childhood immunizations. Generates a CDC/WHO-aligned vaccination timeline based on date of birth to support longitudinal health records.
About
Digital continuity in pediatric healthcare relies on the accurate tracking of preventative care windows. This calculator generates a chronological immunization schedule aligned with recommendations from the CDC and the World Health Organization. It addresses the challenge of health information fragmentation by providing parents and providers with a clear, date-specific roadmap for a child's critical developmental years.
Missed vaccination windows significantly increase the risk of preventable diseases. By converting relative age guidelines (e.g., "2 months") into concrete calendar dates, this tool reduces cognitive load and facilitates better compliance with public health standards. It serves as a foundational component for a longitudinal health record.
Formulas
The scheduling logic computes the target date Dtarget by adding the recommended age interval I to the child's Date of Birth (DOB).
Where interval I is defined in months or years. The calculation accounts for variable month lengths (28, 30, or 31 days) and leap years to ensure calendar accuracy.
