A nurse is preparing to administer vaccines to a 1-year-old child. Which of the following vaccines should the nurse give? (Select all that apply.)

A. Varicella (VAR) vaccine is recommended at 12–15 months of age to protect against chickenpox. Administering it at this age ensures the child develops immunity before potential exposure in early childhood. B. Measles, mumps, rubella (MMR) vaccine is also recommended at 12–15 months. Providing it at this time helps protect the child from these highly contagious viral infections and prevents outbreaks. C. Human papillomavirus (HPV4) vaccine is recommended starting at 11–12 years of age to prevent HPV-related cancers. It is not appropriate for a 1-year-old. D. DTaP (diphtheria, tetanus, and acellular pertussis) series includes doses at 2, 4, 6, and 15–18 months. At 12 months, the child may be due for the 4th dose depending on the immunization schedule, which is why it is included in this visit. E. Rotavirus (RV) vaccine series is completed by 6–8 months of age. Giving it at 1 year is not indicated because the child is past the age window for safe administration.
