Dear .regarding HCV Patogenisis .......Is there any possibility to develop HCV VACCINE passive or active ...thanx

This is not a vaccine, but an antisense treatment approach.

McCaffrey AP, Meuse L, Karimi M, Contag CH, Kay MA. A potent and specific morpholino antisense inhibitor of hepatitis C translation in mice. Hepatology. 2003 Aug;38(2):503-8.

The company AVI BioPharma has similar Moprholino oligos in clinical trials against HCV.

Hope that helps,
