Abstract
Hepatitis C virus infects nearly 3% of the global population, and
spreads to 3-4 million new people annually. HCV infection is a
leading cause of liver cirrhosis, hepatocellular carcinoma, and
end-stage liver diseases and causes liver-related death in more than
300,000 people each year. Unfortunately, there is currently no
vaccine for HCV prevention (prophylactic vaccine) or treatment
(therapeutic vaccine). Circulating HCV is genetically diverse, and
therefore a broadly effective vaccine must target conserved T- and
B-cell epitopes of the virus and induce strong cross-reactive
CD4+/CD8+ T-cell and neutralizing antibody responses in
preventing or clearing HCV infection. So far, a few of vaccine
development approaches are successful and some of the HCV
vaccine candidates have reached human clinical trials, including
those modalities mainly based on recombinant proteins (envelope
proteins and core protein subunit), synthetic peptides, DNA
(plasmid) and viral vectors (virosome). Encouraging results were
obtained for those HCV vaccine formulations consisting of
prime-boost regimen involving a live recombinant viral vector
vaccine alone or in combination with DNA or subunit vaccine.
Among several other vaccine strategies under preclinical
development, the most promising one is virus like particle based
vaccine that will be moving into human studies soon.
