Production of Oncolytic Measles Virus in Vero Cells: Impact of Culture Medium and Multiplicity of Infection.

Oncolytic measles virus (MeV) is a promising anti-cancer treatment. However, the production of high titers of infectious MeV (typically 10-10 TCID per dose) is challenging because the virus is unstable under typical production conditions. The objective of this study was to investigate how the multiplicity of infection (MOI) and different media-a serum-containing medium (SCM), a serum-free medium (SFM) and two chemically defined media (CDM)-affect MeV production.
