A simplified plaque assay for varicella vaccine.
A simple and accurate plaque assay is described for potency testing of attenuated varicella vaccine. Assays were performed on the African green monkey kidney continuous cell line CV-1, in multidish-plates, under a semi-solid carboxymethylcellulose overlay. The test is economical and yields accurate individual titre estimates, the reliability of which may be assessed by parallel titration of reference preparations.
