Infectious Subgenomic Amplicons Reverse genetic system for chimeric virus CH-17D / ZIKV. It consists of three non infectious overlapping DNA fragments (cloned into pUC57 vector) . These products enable to obtain infectious RNA virus after amplification by PCR, and transfection into susceptible cells. The chimeric virus systems were constructed using the yellow fever 17-D vaccine strain as a genetic backbone and by replacing prM/E from this vaccine strain with those of the Asian ZIKV PF epidemic strain.
