ELISPOT in Vaccine Development

ELISPOT and vaccine developmentDeveloping vaccines for the prevention of human infection by different viruses, bacteria or parasites is an urgent task, and relies on a variety of measurements to monitor vaccine efficacy. Primary measurements may be antibody titers to vaccine antigens or the determination of antibody function such as anti-viral neutralizing activity. Additionally, in the last decades the measurement of T cell function can be used to assess vaccine efficacy. The ELISPOT assay is an ideal tool to determine the impact of vaccines on immune mediators such as interleukins, interferons and pro-inflammatory mediators.

One major advantage of the ELISPOT assay is the ability to cost-effectively screen in a relatively short period a wide array of peptide antigens, allowing the detection of T cell responses to an entire pathogen proteome. The assay is capable of distinguishing T cell responses to any epitope of 11 amino acids or even less. Furthermore, responses can be monitored through time in a follow-up, to estimate the induction of a substantial memory response in the vaccine recipients.

So far, ELISPOT assays have helped us remarkably in our understanding of immune responses against different pathogens in the past and still forms a routine basis for many additional investigations and methods, such as flow cytometric analysis or antigen-specific tetramer assays. In the end, the ELISPOT can help us to generate information that can eventually lead to the discovery of more effective vaccines providing protective immunity against different infectious diseases.
