Table 4.

Comparison of positive/negative responses for IFN-γ, IL-2 and TNF-α as measured by multiplex bead array and by ICS.^*

			Multiplex Bead Array
			Negative	Positive
ICS	IL-2	Negative	19	6
	IL-2	Positive	2	13
	IFN-γ	Negative	30	2
	IFN-γ	Positive	5	3
	TNF-α	Negative	29	5
	TNF-α	Positive	1	5

The table reports number of samples determined to have a positive response by one or both assays. Samples were PBMC from 40 vaccine recipients (RV144 trial) collected at week 26 (two weeks after final immunization), stimulated ex vivo with HIV Env peptide pools.
