Comparison of ELISA with electro-chemiluminescence technology for the qualitative and quantitative assessment of serological responses to vaccination
Profiling immune responses induced by either infection or vaccination can provide insight into identification of correlates of protection. Furthermore, profiling of serological responses can be used to identify biomarkers indicative of exposure to pathogens. Conducting such immune surveillance requires readout methods that are high-throughput, robust, and require small sample volumes. While the enzyme-linked immunosorbent assay (ELISA) is the classical readout method for assessing serological responses, the advent of multiplex assays has significantly increased the throughput and capacity for immunoprofiling. This report describes the development and assay performance (sensitivity, linearity of detection, requirement for multiple dilutions for each sample, intra- and inter-assay variability) of an electro-chemiluminescence (ECLIA)-based multiplex assay.
Objectors to applications in public health assert that because it is impossible to obtain informed consent that the technology is inadequate. What a remarkable conclusion!
In the early 1990s, when scientists first came up with a radical new idea to engineer mosquitoes that would no longer be capable of transmitting pathogens, some thought of an even more fantastic application. Use mosquitoes to vaccinate people. Silence followed until now...
