What each source is
Schedules. The WHO summary of position papers (Table 1, updated December 2025) is the global framework the Vaccinations through life guide summarises. The CDC adult and child schedules (United States, 2025) are what the Adult vaccinations guide summarises — US-only, with the court-stay note that keeps them current.
Coverage. The WHO/UNICEF Estimates of National Immunization Coverage (WUENIC), released 15 July 2026, report 2025 data: 90% first DTP dose, 85% full course, 13.5 million zero-dose children. The How many children are vaccinated? guide carries those figures with their year.
Disease context. The WHO fact sheets for cervical cancer (3 July 2026) and hepatitis B (28 July 2026), the WHO measles reporting of November 2025, and the CDC adult schedule are what the What vaccination prevents guide is built from. Travel requirements come from the CDC Yellow Book 2026 and the CDC yellow fever vaccine page, summarised in Travel vaccinations.
Frequently asked questions
Does this page tell me which vaccines I need?
No. It lists the official sources the guides are built from. Schedules live on the official sources; personal questions go to a qualified health professional.
How is this different from the Vaccination Directory?
The Directory links official sources by country. This page links the schedules and data sources themselves — the WHO and CDC schedule documents, the WUENIC coverage release, and the fact sheets.
How often are these sources re-checked?
WUENIC annually each July; the WHO schedule table at each update and at least every 6 months; CDC schedules at every build and every 6 months and immediately on any court or ACIP change.
