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. Pneumococcal conjugate vaccine (PCV): This vaccine is generally completed before the age of 5, so it is not typically administered at this stage. B. Hepatitis B (HBV): The HBV series is usually completed during infancy and early childhood, so it is not needed at 5 years if the child is up to date. C. Haemophilus influenzae type B (Hib): Hib is typically completed by 18 months of age and is not required for pre-kindergarten. D. Measles, mumps, and rubella (MMR): A second dose of MMR is typically required at 4-6 years, aligning with pre-kindergarten vaccination schedules.
