A nurse in a clinic is preparing to administer pre-kindergarten vaccines to a 5-year-old child whose medical record indicates that his Immunizations are up to date. Which of the following vaccines should the nurse plan to administer?

A. Hepatitis B (HBV): The Hepatitis B vaccine is typically completed in the infant stage, and a 5-year-old with up-to-date vaccinations would not need a booster for school entry. This is not included in the pre-kindergarten vaccine schedule. B. Measles, mumps, and rubella (MMR): The MMR vaccine is part of the pre-kindergarten immunization schedule. A second dose is recommended between ages 4 and 6 to ensure immunity before school entry. C. Haemophilus influenzae type B (Hib): The Hib vaccine is typically administered to infants and young children, and a 5-year-old with up-to-date immunizations would already be fully vaccinated against Hib. No booster is required at this age. D. Pneumococcal conjugate vaccine (PCV): The PCV vaccine series is usually completed in infancy, and a 5-year-old with current vaccinations would not require a booster. This vaccine is not part of the pre-kindergarten schedule.
