Which route is used to administer the Rotavirus vaccine?

The Rotavirus vaccine is administered orally, which means the correct response is that it is given by the oral route. This method is significant because it allows the vaccine to act directly in the intestines, where the rotavirus typically causes illness. Administering it orally helps to stimulate an immune response in the gut, providing protection against gastrointestinal diseases caused by rotavirus infection.

The use of the oral route is particularly effective for rotavirus vaccines because it mimics the natural route of infection, enabling the body to generate an appropriate immune response. The convenience of oral administration is also beneficial, especially when vaccinating infants and young children, as it is less invasive and generally better accepted than injections.

Other routes mentioned, such as intramuscular, subcutaneous, and intranasal, are not used for this vaccination. For example, intramuscular and subcutaneous routes are often used for vaccines like hepatitis B or MMR (measles, mumps, rubella), while intranasal routes are used for certain vaccines like the influenza vaccine. However, they do not apply to the administration of the Rotavirus vaccine, making oral the unique and correct choice for this vaccine.
