How do I know which vaccines are due next?
Enter your country and your baby's age to see the next visit in the tool. Every country's schedule was last checked against the official source on 26 September 2026, so always confirm with your national schedule or clinic.
Are vaccine names the same everywhere?
No. Many countries use **combination vaccines** (e.g., “6-in-1”), but brand names differ. The tool uses **generic vaccine types** for clarity.
What if my baby has missed a dose?
Most countries have **catch-up rules**. If a dose was missed, contact your healthcare provider to plan the catch-up doses.
Why does the tool stop at about 18 months?
For most countries this version covers the **infant series** only. The US and UK schedules continue to the pre-school boosters (4–6 years in the US, 3 years 4 months in the UK). School-age and teenage vaccines are beyond scope.
Can I use this tool instead of my doctor’s advice?
No. This tool is an **educational reference only**. Your pediatrician or local health authority has the most accurate and updated schedule for your child.
Do vaccine windows have flexibility?
Yes. Many vaccines have **recommended ranges**. Being a few days early/late usually doesn’t require restarting, but always confirm with your provider.
Why do schedules differ by country?
Differences reflect **local disease prevalence, health policy, and vaccine supply**. For example, BCG (tuberculosis) is routine in some countries but not in others.
