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

The U.S. CDC published 'Universal Hepatitis B Vaccination in Adults Aged 19–59 Years: Updated Recommendations of the Advisory Committee on Immunization Practices — the United States, 2022' on April 1, 2022. Previously, on Feb. 23, 2022, the CDC's Hepatitis Vaccines Work Group presented an update, and the ACIP voted in the affirmative.

Hepatitis A Outbreaks In 2022

As of May 6, 2022, the CDC confirmed that 37 U.S. states had reported hepatitis A cases, and 15 have declared the end to their outbreaks. Since the outbreaks were first identified in 2016, 37 states reported 44,241 cases, hospitalizations (61%), and 420 related fatalities.

Adenovirus Linked Acute Hepatitis in Children Outbreaks In 2022

Hepatitis Vaccines - U.S. FDA Authorized For 2022

Engerix-B is a Hepatitis B Vaccine that is a noninfectious recombinant DNA hepatitis B vaccine.

Havrix Hepatitis A Vaccine is indicated for active immunization against disease caused by the hepatitis A virus.

Hecolin is a recombinant vaccine that contains the hepatitis E virus (HEV)-like particles prepared using a recombinant Escherichia coli expression system.

Heplisav-B combines hepatitis B surface antigen with Dynavax's proprietary Toll-like Receptor (TLR), nine agonists, to enhance the immune response.

Recombivax HB is a recombinant vaccine that contains synthetic Hepatitis B surface antigen (HBsAg). 

Twinrix Hepatitis Vaccine is indicated for active immunization against disease caused by hepatitis A virus and infection by all known subtypes of hepatitis B virus. 

PreHevbrio (Sci-B-Vac) is a third-generation hepatitis B  trivalent vaccine that mimics all three surface antigens, pre-S1, pre-S2, and S, of the hepatitis B virus; approved in Israel and the U.S.

Hepatitis Vaccines Globally

Xiamen Innovax launched the hepatitis E vaccine Hecolin® in October 2012. The vaccine was approved by China's State Food and Drug Administration based on the phase III trial (NCT02189603). In addition, the US NIH notified Xiamen that its Investigational New Drug application of Hecolin (HEV-239) at the FDA became effective on January 12, 2019. 

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.

The prevalence of HIV/HBV coinfection in Spain at the end of 2018 was 3.2%, which does not differ significantly from percentages reported in studies performed over the past 15 years. All HIV/HBV-coinfected patients were on anti-HBV drugs and most of which HBV DNA was fully suppressed. Liver cirrhosis and HDV infection were identified as common problems among HIV/HBV-coinfected patients.

The study plans to enroll 64 patients in South Korea, Taiwan, and the UK.

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.

"Evidence consistently shows that screening and early treatment leads to better health outcomes."

July 18, 2020 - The USA has been experiencing person-to-person outbreaks of hepatitis A in unprecedented numbers during the vaccine era. As of May 2020, 33 states had reported hepatitis A outbreaks involving approximately 32,500 cases reported by the Centers for Disease Control and Prevention.
