Rotavirus vaccine


There are two versions of this vaccine:

  • One of them comes with a lyophilized (freeze dried) powder and a diluent (liquid to dissolve the powder in). These are mixed together and given in a 1mL dose.

  • The other version comes as a liquid with all of the ingredients already mixed together. This version is given in a 1.5mL dose.

Both of these versions are given orally (by mouth) and not as an injection.
