A nurse is assisting with planning care for a 2-month-old infant during a well-child visit. The nurse should plan to administer which of the following Immunizations?

A. Rotavirus (RV): The first dose of the rotavirus vaccine is recommended at 2 months of age as part of the routine immunization schedule. Rotavirus vaccination protects infants from severe gastroenteritis caused by rotavirus, which can lead to dehydration and hospitalization. Administration at this age supports early immunity before peak exposure to the virus. B. Measles, mumps, and rubella (MMR): The MMR vaccine is typically administered starting at 12 months of age, with a second dose at 4–6 years. Giving it at 2 months is not appropriate because maternal antibodies can interfere with vaccine efficacy, and the infant’s immune system is not sufficiently mature to mount an adequate response. C. Varicella (VAR): Varicella vaccination is also recommended at 12 months of age, with a second dose at 4–6 years. Administering it at 2 months would be ineffective due to interference from maternal antibodies and the immature immune system. D. Influenza (IV): Routine influenza vaccination is recommended starting at 6 months of age. Infants younger than 6 months are !not eligible for the vaccine, so it is not appropriate to administer during a 2-month well-child visit.
