Baby Vaccine Schedule Calculator
Last updated: 2026-06-25
Enter your baby's birth date and this tool calculates the recommended due dates for each vaccine — BCG, Hepatitis B, DTaP, Polio, Hib, PCV, Rotavirus, MMR, Varicella and more — on the standard immunization schedule.
Recommended dates are standard timings, and a few days' delay usually lets you continue. Confirm the final schedule with your pediatrician or public health center.

This schedule is a reference estimate based on a standard immunization schedule. It may vary by vaccine type and your baby's health, so confirm the actual schedule with your pediatrician, public health center, or your local immunization authority.
How to use
- Enter birth date — select your baby's date of birth.
- Run the calculation — press the Calculate schedule button.
- View the schedule — the recommended due date and age for each vaccine are shown in a table with dates.
The standard immunization schedule
National immunization programs provide the vaccines infants need, often at no cost at designated clinics and public health centers. This calculator adds each vaccine's recommended age (in months or years) to your baby's birth date to compute the recommended due date, based on a standard immunization schedule.
| Vaccine | Timing |
|---|---|
| BCG (tuberculosis, intradermal) | within 4 weeks of birth |
| Hepatitis B (HepB) | at birth · 1 month · 6 months (3 doses) |
| DTaP (diphtheria, tetanus, pertussis) | 2 · 4 · 6 months, 15-18 months, 4-6 years (5 doses) |
| Polio (IPV) | 2 · 4 · 6 months, 4-6 years (4 doses) |
| Hib (H. influenzae type b) | 2 · 4 · 6 months, 12-15 months (4 doses) |
| Pneumococcal (PCV) | 2 · 4 · 6 months, 12-15 months (4 doses) |
| Rotavirus (RV) | 2 · 4 months (or 2·4·6 months, by product) |
| MMR (measles, mumps, rubella) | 12-15 months, 4-6 years (2 doses) |
| Varicella (VAR) | 12-15 months (1 dose) |
| Hepatitis A (HepA) | 12-23 months, plus a dose 6 months later (2 doses) |
| Japanese encephalitis (inactivated) | starts at 12-23 months |
| Influenza | every year from 6 months of age |
The dates shown are estimates based on the start of each recommended age. Vaccines recommended at the same time can be given on the same day, or combination vaccines (DTaP-IPV-Hib-HepB) can reduce the number of shots. To check your baby's growth, try the infant growth percentile calculator.
Frequently asked questions (FAQ)
Are routine childhood vaccines free?
In many countries, vaccines on the national immunization program are provided at no out-of-pocket cost at designated clinics and public health centers. These typically include BCG, Hepatitis B, DTaP, IPV (polio), Hib, PCV (pneumococcal), Rotavirus, MMR, Varicella, Hepatitis A, and influenza. Check your local public health authority for details.
Is it okay if a dose is a little later than the recommended date?
The recommended date is the most effective standard timing, and a delay of a few days to weeks usually lets you continue the schedule. However, each vaccine has minimum intervals and upper age limits (for example, the first rotavirus dose is recommended before 15 weeks of age), so if you are behind, do not guess — set a catch-up schedule with your pediatrician or clinic.
Can several vaccines be given on the same day?
Yes. Vaccines recommended at the same time in the standard schedule can be given on the same day, and this is proven to be safe and effective. Using combination vaccines (e.g. DTaP-IPV-Hib-HepB) can reduce the number of shots. Discuss co-administration with your provider.
Is this calculator's schedule accurate?
This calculator computes the dates that fall on the recommended ages of a standard immunization schedule as a reference tool. The actual schedule may differ by vaccine type (e.g. combination vaccines, rotavirus products) or your baby's health, so always confirm the final schedule with your pediatrician or public health center.
