background the impact of hepatitis b virus (hbv) vaccination campaigns on hbv epidemiology needs to be evaluated, in order to assess the long-term immunity offered by vaccines against hbv. objectives to evaluate the current status of anti-hbv vaccine coverage among healthcare workers (hcws) in southern italy, and to determine the long-term persistence of antibodies to hepatitis b surface antige...

Persistence of antibodies 20 y after vaccination with a combined hepatitis A and B vaccine

Vaccination is the most effective and well-tolerated method of conferring long-term protection against hepatitis A and B viruses (HAV; HBV). Long-term studies are required to characterize the duration of protection and need for boosters. Following primary immunization of 150 and 157 healthy adults with 3-doses of combined hepatitis A/hepatitis B vaccine (HAB; Twinrix™, GSK Vaccines, Belgium) at...

Determinants of Long-term protection after hepatitis B vaccination in infancy: a meta-analysis.

BACKGROUND The duration of protection after hepatitis B vaccination in early infancy is unclear and may be related to vaccination schedule, dosage, vaccine type and population characteristics. Factors potentially influencing waning immunity were assessed. METHODS A systematic review was performed. The main outcomes were prevalence of anti-hepatits B antibodies ≥ 10 mIU/mL after primary or boo...
