Hepatitis Vaccines For 2022
The vision of the U.S. CDC is to eliminate viral hepatitis globally. The five hepatitis viruses – hepatitis A, hepatitis B, hepatitis C, hepatitis D, and hepatitis E – are distinct and can spread in different ways, affect diverse populations, and result in various health outcomes.
One dose of single-antigen hepatitis A vaccine has been shown to control outbreaks of hepatitis A successfully, says the CDC. And the CDC's Advisory Committee on Immunization Practices (ACIP) recommends various people receive hepatitis B vaccination.
In addition to groups for whom HepB vaccination is already recommended, the ACIP recommended on April 1, 2022, that all adults aged 19–59 years should receive HepB vaccines.
Hepatitis Vaccine Schedules For 2022
The U.S. CDC released updated hepatitis vaccination schedules for children, adolescents, and adults on Feb. 17, 2022.
Hepatitis B Vaccine Schedule For 2022

Previously, on Feb. 23, 2022, the CDC's Hepatitis Vaccines Work Group presented an update, and the ACIP voted in the affirmative.

Hepatitis Vaccine Candidates For 2022
HBAI20 vaccine candidate consists of a standard HBV vaccine to which the AI20 adjuvant is added.
VBI-2601 (BRII-179) is a novel recombinant, protein-based HBV immunotherapeutic candidate that builds upon the 3-antigen conformation of VBI's prophylactic 3-antigen HBV vaccine candidate and is designed to target enhanced B-cell and T-cell immunity.
VTP-300 vaccine candidate utilizes Vaccitech's ChAdOx1-MVA prime-boost combination to elicit an immune response against HBV. The HBV DNA sequence in the viral vectors is derived from a genotype C sequence, the most common genotype circulating worldwide.
VIR-2218 and VIR-3434 combination - VIR-2218 is an investigational small interfering ribonucleic acid (siRNA) designed to inhibit the production of all HBV proteins (X, polymerase, S, and core), which may be acting as immune tolerogens. VIR-3434 is an investigational HBV-neutralizing monoclonal antibody designed to block the entry of all ten genotypes of HBV into hepatocytes and reduce the level of virions and subviral particles in the blood. It has also been Fc engineered to include the XX2 "vaccinal mutation," allowing it to potentially function as a therapeutic T cell vaccine against HBV.
Antios Therapeutics' lead once-daily oral drug candidate for treating HBV ATI-2173 is an investigational phosphoramidate prodrug of clevudine monophosphate. ATI-2173 is the only Active Site Polymerase Inhibitor Nucleotide for HBV in clinical development.

January 25, 2021 - Atlanta-based Antios Therapeutics, Inc. announced that it had completed the Phase 1b clinical trial of ATI-2173, an Active Site Polymerase Inhibitor Nucleotide (ASPIN), in patients with chronic hepatitis B virus infection. ATI-2173 is a novel, orally-administered, liver-targeted Active Site Polymerase Inhibitor Nucleotide (ASPIN) molecule designed to deliver the 5’-monophosphate of clevudine to the liver. This L-nucleoside's active 5’-triphosphate has unique antiviral properties as a non-competitive, non-chain terminating HBV polymerase inhibitor that distorts HBV polymerase's active site, resulting in potent HBV antiviral activity and extended off-treatment suppression of HBV DNA. In addition, ATI-2173 targets the liver, delivering high levels of the unique 5'- triphosphate while limiting systemic exposure to the parent L-nucleoside. Thus, ATI-2173 has the potential to become an integral part of a curative combination regimen for chronic hepatitis B.
