Immunogenicity of Twinrix™ in older adults: a critical analysis

Abstract

Twinrix™(GlaxoSmithKline Biologicals, Rixensart, Belgium) is the first combined vaccine to provide protection against both hepatitis A and B. This review presents a critical analysis of antibody responses stratified by age following vaccination with Twinrix in 264 adults aged above 40 years. A month after completion of a 0-, 1-, 6-month vaccination schedule with Twinrix, a good response was observed for both anti-HAV and anti-HBs serum antibodies, suggesting that is an effective vaccine in older adults.
