What shots are due at the 12-month visit?
At the 12-month visit the on-time CDC schedule lists 5 vaccines (Hib, PCV, MMR, VAR and HepA): 5 shots. By the end of this visit 23 of the 29 routine doses have been listed.
Key takeaways
- 5 doses are due at 12 months: Hib 4/4, PCV 4/4, MMR 1/2, VAR 1/2, HepA 1/2.
- Running total: 23 of 29 routine doses by this visit, 6 still to come.
- None of the 5 doses at 12 months has a hard age limit, so each can be moved if your clinician agrees. This is the on-time schedule, and your clinician sets your visit.
Due at 12 months
| Vaccine | Dose | Protects against | Can it wait? |
|---|---|---|---|
| Hib | 4 of 4 | Hib (a cause of meningitis & epiglottitis) | Can wait for fewer doses (3 doses if the first is at 7 to 11 months; 2 doses if the first is at 12 to 14 months; 1 dose if the first is at 15 to 59 months); none from age 5. |
| PCV | 4 of 4 | Pneumococcal disease (pneumonia, meningitis, ear infections) | Can wait for fewer doses (3 doses if the first is at 7 to 11 months; 2 doses if the first is at 12 to 23 months; 1 dose if the first is at 24 to 59 months); none from age 5. |
| MMR | 1 of 2 | Measles, mumps, rubella | No fewer doses by waiting (2); the next dose follows at least 4 weeks later. |
| VAR | 1 of 2 | Chickenpox | No fewer doses by waiting (2); the next dose follows at least 3 months later. |
| HepA | 1 of 2 | Hepatitis A | No fewer doses by waiting (2); the next dose follows at least 6 months later. |
This is the on-time schedule. Your clinician sets your visit and may combine, move or skip items for your child. Counts follow the planner's routine series (4 Hib, 3 rotavirus); some products need one dose fewer.
Also allowed in this window
- HepB dose 3 (CDC window 6 months to 18 months) can be given at 12 months; usually given earlier, so check whether it is already done.
- IPV dose 3 (CDC window 6 months to 18 months) can be given at 12 months; usually given earlier, so check whether it is already done.
Questions parents ask about this visit
How many shots at the 12-month visit?
The on-time schedule lists 5 vaccines at 12 months: 5 shots. 2 more doses can also be given in this window (HepB 3 and IPV 3).
Can the 12-month shots be spaced out?
At 12 months, dose by dose: Hib and PCV can be started later with fewer doses; MMR, VAR and HepA can be spaced but keep their dose count. Your clinician sets the actual plan.
Can MMR and varicella go in the same visit at 12 months?
They are both due, and the planner's note says: Give MMR and Varicella as separate shots before age 4 (lower febrile-seizure risk). That means two separate injections, which can still be the same visit. MMR's second dose needs 4 weeks after the first; varicella's needs 3 months.
Space these shots out with the planner
Choose how many vaccines per visit and how far apart; the planner checks every minimum age and interval.
