Most importantly, depletion of CD4 + T cells in vaccinated mice resulted in loss of protection, with 100% succumbing to infection upon challenge with wild-type CHIKV, indicating an indispensable role of MVA-CHIK immune CD4+ T cells in protection. Expression of E2 was observed in the supernatant of CHIKV infected cells, but there Prior to boost (where applicable) and challenge, mice were bled and serum was monitored for both total Ig(G+M) and neutralizing activity by TCID 50 was no detection of E2 expression in MVA-CHIK, suggesting that the protein was not being secreted. ./cache/cord-001365-6u80p5sj.txt ./txt/cord-001365-6u80p5sj.txt
