A hepatitis C vaccine, a vaccine capable of protecting against the hepatitis C virus (HCV), is not yet available. Although vaccines exist for hepatitis A and hepatitis B, development of an HCV vaccine has presented challenges. [1] No vaccine is currently available, but several vaccines are currently under development. [2] [3]
Chronic hepatitis C is defined as infection with the hepatitis C virus persisting for more than six months based on the presence of its RNA. [18] Chronic infections are typically asymptomatic during the first few decades, [ 18 ] and thus are most commonly discovered following the investigation of elevated liver enzyme levels or during a routine ...
E2 is a viral structural protein found in the hepatitis C virus. [1] [2] It is present on the viral envelope and functions as a host receptor binding protein, mediating entry into host cells. It is a key target for the design of entry inhibitors and vaccine immunogens. [3]
The hepatitis C virus (HCV) [3] is a small (55–65 nm in size), enveloped, positive-sense single-stranded RNA virus of the family Flaviviridae. The hepatitis C virus is the cause of hepatitis C and some cancers such as liver cancer ( hepatocellular carcinoma , abbreviated HCC) and lymphomas in humans.
Once hepatitis C was identified in 1989, blood banks began screening all blood donors for the presence of the virus in their bloodstream. However, since hepatitis C is known to have been present since at least the 1940s, a gamma globulin shot received prior to the early 1990s put the recipient at risk of being infected.
A hexavalent vaccine, or 6-in-1 vaccine, is a combination vaccine with six individual vaccines conjugated into one, intended to protect people from multiple diseases. [1] [9] The term usually refers to the children's vaccine that protects against diphtheria, tetanus, pertussis, poliomyelitis, haemophilus B, and hepatitis B, [1] [9] which is used in more than 90 countries around the world ...
Combined hepatitis A and B vaccine, is used to provide protection against hepatitis A and hepatitis B. [3] [7] It is given by injection into muscle.[8]It is used in areas where hepatitis A and B are endemic, for travelers, people with hepatitis C or chronic liver disease, and those at high risk of sexually transmitted diseases.
