A calm guide to the baby vaccination schedule: what changes by country, what to record, and how Sunny Seed helps parents keep reminders and history together.
A baby vaccination schedule can feel like a long list of dates, abbreviations, and country-specific rules. The practical goal is simpler: know what is coming next, record what was done, and keep enough detail to discuss questions with your pediatrician.
Sunny Seed treats vaccines as part of the child’s health history, next to growth, sleep, feeding, milestones, and diary notes — not as a place for self-diagnosis or medical decisions. The calendars are copied from national health authorities; Sunny Seed is not affiliated with any of them and does not issue medical guidance.
Vaccination timing, contraindications, catch-up plans, and local requirements should always be confirmed with your pediatrician or local health authority. An app can organize records and reminders; it does not replace medical advice.
There is no single universal schedule that works perfectly for every family. National recommendations differ because health systems, vaccine availability, disease risk, and school or childcare rules differ.
Sunny Seed carries 19 national calendars, each taken from that country’s own health authority, plus the WHO schedule as the fallback for anywhere else:
Five vaccines appear in the routine part of every one of them: hepatitis B, a DTP-type vaccine (DTaP or whole-cell DTP), polio, Hib, and a measles-containing vaccine. Pneumococcal comes close but misses by one — Ukraine keeps it for at-risk infants rather than in the routine course, so a Ukrainian calendar shows no routine PCV dose and generates no reminder for it.
Everything else varies more openly. The UK schedule counts early doses in weeks while Germany counts them in months; Germany uses a 2+1 scheme for several vaccines; Russia’s base calendar has no rotavirus dose, where most Western European schedules do.
If you would rather look up one age than read a whole calendar, the month-by-month pages set out the doses the US and UK schedules place at each month, next to the growth and sleep figures for that age.
A useful vaccine log is not just “done” or “not done.” In Sunny Seed each dose keeps:
Two things stay on paper: the batch number and the clinic stamp. Keep the official card for those — it is what a school, a new pediatrician, or a border will ask for. If the appointment left you with something to watch or ask about, write it as a diary entry for that day.
This matters if you move, change pediatricians, travel, or need to reconstruct a record later.
For growth and development, premature babies may use corrected age in some contexts. Vaccines are different.
For vaccinations, Sunny Seed uses chronological age — even for premature babies. Corrected age is used for growth and developmental context, not for vaccine scheduling.
If your baby was born prematurely or has a medical condition, ask your pediatrician how your local schedule applies to your child.
Sunny Seed is designed to keep the vaccination calendar close to the rest of your baby’s story:
This makes the app useful before a pediatrician visit: you can quickly see what was done, what is coming next, and which questions you want to ask.
A tracker should reduce chaos, not create pressure. It should not decide whether a vaccine is appropriate for your child, interpret symptoms, or replace your local immunization guidance.
Use the app to prepare better questions:
If you are building a complete health history, these guides may help:
Before the appointment itself, it helps to know what to bring — see baby doctor visit checklist.
Track the vaccine name, dose number, planned date, and the date it was actually given. Batch numbers and clinic stamps belong on the official paper card — keep that safe alongside the app.
Yes, if the app has country-specific calendars. Sunny Seed carries 19 national calendars plus the WHO schedule, and follows the one selected for your child rather than a generic list. A country outside those 19 falls back to the WHO schedule.
In Sunny Seed, vaccine dates are based on chronological age. Corrected age is reserved for growth and developmental context. Always confirm medical timing with your pediatrician.
No. Sunny Seed helps you organize records, reminders, and history. Decisions about vaccines, timing, contraindications, and catch-up schedules belong with your pediatrician and local health authority.
