Every country has its own official vaccination schedule, with vaccine names and combinations that vary. What does repeat across almost every schedule in the world is the ages where doses cluster — and that pattern is what helps you never miss one, wherever you live.
Ages where doses cluster, across most schedules
| Age | What usually comes up |
|---|---|
| At birth | First dose of the schedule, at the hospital |
| 2 months | First block of multiple boosters |
| 4 months | Second dose of the same block |
| 6 months | Third dose of the block, plus seasonal vaccines depending on the country |
| 12 months | First major booster of the first year |
| 15-18 months | Second block of boosters |
This table is an age guide, not a medical schedule — the specific vaccines, their names, and the exact number of doses at each point are set by your country's health authority. What it's useful for is keeping in mind when to check the record, not replacing the official calendar.
How to never miss a dose
- Log every checkup in the same place you track the rest of your baby's routine, not a loose piece of paper that can get lost.
- Bring the physical record or a photo of it to every appointment, even if the health system has digital records — don't rely on it being "already loaded."
- Note the likely next date right as you leave a checkup, instead of trusting yourself to remember it two months later.
If you move countries mid-schedule
No need to restart anything. Bring the full history (paper or digital record) to the first appointment with the new pediatrician — most schedules can be matched up by comparing the age each dose was given and the type of vaccine, regardless of the brand name changing from one country to another.

Frequently asked questions
Why does the vaccine schedule change by country?
Each country sets its schedule based on local epidemiology and its own public health criteria — the ages are quite similar, the specific vaccines vary.
What do we do if we move countries mid-schedule?
Bring the full record to the first appointment — it can be matched up by comparing ages and vaccine types, no need to start over.
What happens if we fall behind on a dose?
Usually there's no need to restart the schedule — it picks up from the missed dose, as the pediatrician decides.
