WHO workshop in Training Performance of Rotavirus Vaccine Potency Testing

Rotavirus vaccines are an urgent need for the control of the rotavirus infection in the world. The introduction of these vaccines, in particular to developing countries, will support the effort in controlling the disease. The capacity of the national control laboratories (NCLs) in testing the vaccine is a crucial part of the process for vaccine licensure and regulation. Potency testing is critical for assuring the efficacy of the vaccines. The status of the rotavirus vaccine potency testing and control in some countries around the world has been investigated through a Questionnaire sent to the NCLs by WHO.
