Reliable analysis of rare virus-specific T cells 

T cells play a pivotal role in fighting viral infections and generating long-term protective immunity after infection and vaccination. 

Assessment of specificity, phenotype, and cytokine secretion of rare virus-reactive T cells can provide essential information on infection progression, prior infections or vaccination efficacy.
