As dengue vaccines enter clinical trials, there is a need for rapid and quantitative assays to measure neutralization. We have developed flow-based neutralization assays which generated results similar to those generated by the established, plaque reduction neutralization test. The flow assays are an improvement, as they use human cells and allow for high-throughput screening.
