Experimental-scale measles and mumps vaccine production on microcarrier-grown cells.

Small-scale measles and mumps virus propagation in microcarrier-grown cells was studied to assess putative advantages over conventional roller-type virus propagation. Significantly higher virus yields could not be attained with microcarrier cultures in cell stirrers, therefore making the advantages purely technological. The pattern of measles virus production was slightly different for the three types of microcarriers used. Experimental measles and mumps vaccine lots obtained met vaccine quality control requirements.
