The 4-year well-child visit includes which vaccines?

• A. Hib, IPV, MMR, Varicella
• B. DTaP, IPV, Hep B, Varicella
• C. DTaP, Hib, MMR, Varicella
• D. DTaP, IPV, MMR, Varicella

Answer: (D)

At the 4-year well-child visit, the vaccines given align with completing the early childhood series and covering the booster doses timed for that age. The four vaccines typically scheduled are DTaP (diphtheria, tetanus, and acellular pertussis) to boost protection against those diseases, IPV (polio) as a booster, MMR (measles, mumps, rubella) with its second dose due around this age, and Varicella (chickenpox) with its second dose also due by preschool years. Hib and Hepatitis B are usually completed earlier in infancy and toddlerhood, so they’re not routinely given at this visit unless there’s a specific catch-up need. Therefore, the standard 4-year visit includes DTaP, IPV, MMR, and Varicella.
