What the defaults give
At 6 months the routine schedule lists the 2-month set (DTaP, IPV, Hib, PCV, rotavirus), the 4-month repeat, and a 6-month visit covering hepatitis B, DTaP, IPV, Hib, PCV, rotavirus and influenza.
The earlier hepatitis B doses at 1–2 months also appear. This is a reference list, not a prescription — the child’s record and clinician decide what is actually due.
How the list is built
Each entry has a minimum age at which it enters the schedule. The tool includes every item whose age threshold is at or below the age you enter, so six months shows the 1–2 month, 2 month, 4 month and 6 month rows stacked together rather than only the newest one.
What appears at each age
1–2 months → hepatitis B
2 months → DTaP, IPV, Hib, PCV, rotavirus
4 months → the same five again
6 months → hepatitis B, DTaP, IPV, Hib, PCV, rotavirus, influenza
12 months → MMR, varicella, hepatitis A, PCV booster
15 months → DTaP booster
4–6 years → DTaP, IPV, MMR and varicella boosters
Reading the list as "everything due today" is the main mistake. A six-month-old has already had the two- and four-month sets in most cases; what the page shows is the cumulative schedule, not a stack of injections for one visit.
Why the exact dates drift
National schedules differ. The ages above follow the routine US childhood schedule; the UK, Canada, Australia and the EU each sequence the same vaccines at slightly different months and sometimes with different combinations. A child vaccinated in two countries will have a record that does not match either schedule line for line, and that is normal.
Catch-up is a separate calculation. Missing a dose does not restart the series in most cases; a clinician applies minimum intervals between doses and works forward from the last one given. That arithmetic is not something a fixed table can do, and the page says so.
What this page is for
It is useful for one thing: seeing roughly which visits fall around a given age, so a parent can check a record and ask a better question. It is not a substitute for the immunisation schedule issued by a health authority, and it should never be used to decide that a vaccine is not needed.
Bring the actual record to the appointment — dates, brands and batch numbers. The clinician has the current schedule and the child’s history; this table has neither.
Frequently Asked Questions
Which vaccines are due at 6 months?
On the routine US list: hepatitis B, DTaP, IPV, Hib, PCV, rotavirus and influenza. The 2- and 4-month sets are also shown, but those are usually already given.
Does the list mean all of these at one visit?
No. It is cumulative: every row whose minimum age has passed. Only the newest row is normally given at that visit.
What if my child missed a dose?
Catch-up uses minimum intervals — often 4 weeks between doses in a series — rather than restarting it. A clinician calculates the next date from the last dose given.
Do other countries use the same schedule?
No. The timing and combinations differ between countries, so use the schedule issued where the child is being vaccinated.
Is this medical advice?
No. It is a reference list built from a published schedule. Decisions belong with the child’s clinician and the official national schedule.
