How recommendations are created
VaxGuide AI does not ask a generative model to invent vaccine advice. Recommendations come from a structured rules database covering age ranges, country of residence, destination countries, pregnancy status, health conditions, occupation and exposure, previous doses and booster intervals.
AI is used only to help explain those rule-based results in plain language. The rule set shipped with this prototype is clearly marked sample data and is intended to be replaced with verified WHO and national immunization datasets.
Country aware
Designed for international use, not for one country's schedule.
Travel logic
Separates recommended vaccines from those that may be required for entry.
Risk aware
Pregnancy, immune status and chronic conditions change the output.
Updatable
Rules live apart from the interface so datasets can be swapped in.
Built around trusted public-health guidance
These are the types of sources this guide is designed to reference. Listing them does not imply any partnership or endorsement.
WHO
World Health Organization position papers and immunization schedules.
National health authorities
Ministry of health guidance for the country you live in.
CDC Travel Health
Destination-based travel health recommendations.
National immunization programs
Routine childhood and adult schedules by country.

This is an educational vaccination guide, not a medical diagnosis or prescription. Vaccination recommendations can vary based on your medical history, previous doses, pregnancy status, immune status, and local public-health guidance. Confirm recommendations with a qualified healthcare professional.
