However, although vaccines for hepatitis A and B are available, no vaccine has yet been developed that can prevent infection with any strain of HCV
There are many strains of HCV and often many thousands of different strains can be found in a single patient. This is because HCV is an RNA virus, and mutates very rapidly. Now, UK researchers are designing a vaccine that will target a specific region of the virus which is the same across all variants, and which the virus needs in order to infect cells.
Researchers from Nottingham University isolated strains of the virus from around the world and extracted the genes for the glycoproteins E1 and E2 which are found on the surface of the envelope of the virus. The virus uses these proteins to attach itself to human cells and to gain entry and infect the cells.
