At well-child visit, which vaccines are typically given at 12-15 months?

• A. MMR and Varicella vaccines (and Hepatitis A may begin at 12 months, but MMR/Varicella are standard at 12-15 months).
• B. DTaP and Hib.
• C. Polio vaccine only.
• D. Influenza yearly.

Answer: (A)

At 12 to 15 months, the vaccines most commonly given together are the MMR and Varicella vaccines. These two are live vaccines that are routinely administered during the same visit because they can be given safely in that window and help complete two important protections with one appointment. Hepatitis A may also be started at 12 months, with the first dose followed by a second dose later, usually 6 to 18 months after the first.

DTaP and Hib have earlier dosing schedules, often started in the first year and given across multiple visits before or around the 12–15 month range, so they’re not the defining vaccines for that specific well-child visit. Polio vaccines are typically completed by the end of the toddler years, and influenza is given annually but not tied to a single window like 12–15 months.
