background and aims: dna constructs containing hcv antigens have become one of the vaccine candidates for induction of anti-hcv cellular and humoral immunity. in this study, we constructed a novel expressing vector harboring a fusion sequence derived from an overlapping fragment in the middle of ns3 and a truncated core fragment to avoid troubles reported to be associated with full gene express...
Viral hepatitis is the most common cause of liver disease in the world. In the past 30 years, highly effective vaccines have become available for two of the five hepatitis viruses, and where implemented, vaccination has become a key component of hepatitis prevention. To provide a current review and critical analysis of the viral hepatitis, A (HAV) and B (HBV) prevention by immunization has be...
LEARNING OBJECTIVES After completion of this chapter individuals should be able to: 1 Define hepatitis and its symptomatology. 2 Distinguish between the various viruses associated with hepatitis. 3 Describe the general features of hepatitis A, hepatitis B, hepatitis C, hepatitis D, and hepatitis E, including the etiology, transmission, diagnosis, sequelae, and prophylaxis. 4 List and discuss th...
Chronic hepatitis B is still a major public health issue despite the successful prophylactic vaccination attempts. Chronicity of hepatitis B virus(HBV) is mainly due to its ability to debilitate host's immune system. Therefore, major measures have been taken to stop this process and help patients with chronic hepatitis B infection recover from their illness. While satisfactory results have been...
Viral hepatitis continues to be the leading cause of morbidity and mortality worldwide, but burden has significantly diminished thanks large-scale use vaccines antivirals. However, there are still challenges regarding viral management, especially when more than one pathogenic agent is involved.

OBJECTIVE To present an updated review and criticism of viral hepatitis A and B prevention by immunization. SOURCES OF DATA Review of medical articles obtained from the MEDLINE database. The most recent and representative articles on the subject (2000-2006) were selected. The Centers for Disease Control and Prevention (CDC), American Academy of Pediatrics (AAP), Brazilian Society of Pediatric...
The essential role of multispecific immune responses for the control of hepatitis B virus (HBV) infection implies the need of multimodal therapeutic strategies for chronic HBV infection, including antiviral chemotherapy and immunomodulation. This hypothesis was tested in the woodchuck model by a combination of lamivudine pretreatment and subsequent immunizations of woodchucks chronically infect...
Hepatitis means inflammation of the liver. The liver is just one of several organs that the viruses affect. There are several hepatitis viruses; they have been named types A, B, C, D, E and G. The most common types of viral hepatitis are HAV, HBV and HCV.

Mankind probably has known viral hepatitis for many centuries; however, the major and most dramatic developments in our knowledge of these diseases have taken place during the second half of the 20th century. During this relatively short period of time, the infectious nature of hepatitis A, B, and C has been proven, leading to their identification and description. The advent of serologic marker...
