Which of the following live vaccines is recommended to be administered prior to one year of age?

The rotavirus vaccine is indeed recommended for administration prior to one year of age and is typically given to infants as part of their early immunization schedule. The vaccine is very important because it provides protection against rotavirus, which can cause severe gastroenteritis, leading to dehydration and hospitalization in young children. The current guidelines recommend that infants receive their first dose of the rotavirus vaccine at 2 months of age, with additional doses given at 4 months and potentially 6 months, depending on the brand used.

In contrast, while varicella, measles, and intranasal influenza vaccines are all crucial for immunization, the timing for their administration differs. The varicella vaccine is usually recommended for children aged 12 months and older, the measles vaccine is part of the MMR (measles, mumps, and rubella) vaccine and is also recommended to begin at 12 months of age, and the intranasal influenza vaccine is typically given annually starting at 2 years of age. Thus, the early recommendation for the rotavirus vaccine is a key aspect of pediatric preventive care, making it vital for reducing disease burden before the age of one year.
