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. Measles, mumps, rubella (MMR): MMR is routinely given at 12 to 15 months of age as part of the standard childhood immunization schedule. At 1 year old, the child’s immune system is developed enough to respond effectively to this live attenuated vaccine. B. Diphtheria, tetanus, and acellular pertussis (DTaP): The DTaP vaccine is given in a series, with doses at 2, 4, 6, and 15–18 months, and a booster at 4–6 years. At 1 year old, the child is due for the fourth dose between 15–18 months, so it may be administered if the child is nearing that window, depending on prior schedule adherence. C. Varicella (VAR): The varicella vaccine is recommended for children starting at 12 to 15 months of age. Since the child is now 1 year old, this vaccine is appropriate and helps prevent chickenpox, a highly contagious viral illness. D. Rotavirus (RV): The final dose of the rotavirus vaccine series must be administered by 8 months of age. A 1-year-old is past the recommended age window for rotavirus vaccination, and administering it now is not recommended. E. Human papillomavirus (HPV): The HPV vaccine is not given to children as young as 1 year old. It is typically administered starting at 11 to 12 years of age to prevent HPV-related diseases such as cervical and other cancers.
