A nurse is preparing to administer a vaccine to a 4-year-old child. Which of the following vaccines should the nurse administer?

A. The meningococcal (MCV4) vaccine is typically recommended for preteens and adolescents, usually starting at age 11. B. The hepatitis B vaccine is typically administered at birth, 1-2 months, and 6-18 months, so a 4-year-old may already have received this vaccine. C. The varicella (VAR) vaccine is recommended for children at ages 12-15 months and again at 4-6 years, making it appropriate for a 4-year-old child. D. The Haemophilus influenza type b (Hib) vaccine is usually given to children in a series before 5 years of age, but it is more commonly completed by age 2-3 years. The 4-year-old may already be up to date with this vaccine.
