Brief Summary

The hepatitis A virus (HAV) is a significant global public health concern. The hepatitis A virus is transmitted primarily by the faecal-oral route, leading to acute hepatitis. Symptoms include low-grade fever, anorexia, jaundice, and typically resolve without complications. However, HAV infection in patients with chronic liver disease, especially those over 50 years old, may result in more severe outcomes, including fulminant hepatitis, with a higher mortality rate compared to the general population HAV vaccination is a cornerstone of prevention, especially in high-risk groups. Currently, there is a recommendation to vaccinate patients with chronic liver disease against HAV infection. However, these patients often have compromised immune responses, leading to lower vaccine efficacy compared to the general population. The goal of this randomized controlled trial is to compare the efficacy and safety of the standard 2-dose (0, 6 months) hepatitis A vaccination regimen with an intensive 3-dose (0, 1, 6 months) schedule in patients with advanced fibrosis and cirrhosis. The main questions it aims to answer are:

  • Compared the seroconversion rate of the standard 2-dose (0, 6 months) hepatitis A vaccination regimen versus the intensive 3-dose (0, 1, 6 months) hepatitis A vaccination regimen in patients with advanced fibrosis and cirrhosis.
  • Compared the antibody levels against the hepatitis A virus (Anti-HAV IgG) of the standard 2-dose (0, 6 months) hepatitis A vaccination regimen versus the intensive 3-dose (0, 1, 6 months) hepatitis A vaccination regimen in patients with advanced fibrosis and cirrhosis.

Outcome Measures

Primary Outcomes (1)

  • Post-vaccination serological response rate

    To compare the seroconversion response rate at month 7 Subjects are considered as being seroconversion if they were initially seronegative and become seropositive

    At 7 months after complete vaccine administration

Secondary Outcomes (5)

  • Post-vaccination serological response

    At 30 days after first dose administration

  • Post-vaccination serological response

    At 1 year after first dose administration

  • Anti-hepatitis A Virus (HAV) antibody at month 1

    At 30 days after first dose administration

  • Anti-hepatitis A Virus (HAV) antibody at month 7

    At 7 months after complete vaccine administration
