Zika Vaccines For 2022

Zika vaccine candidate research has been active for the past few years, and previous study results suggest that a vaccine can be developed. However, the U.S. FDA has not approved any Zika vaccine as of September 7, 2022.

Clinical trials involving DNA and purified inactivated virus vaccines showed they were potentially safe and well-tolerated in small studies and induced neutralizing antibodies. However, these vaccine studies varied by type of vaccine and dosing regimen.

Zika Vaccine Candidates - 2022

TAK-426 (PIZV) is a purified, inactivated, alum-adjuvanted, whole Zika virus vaccine candidate. The vaccine being tested in a phase 1 study is called PIZV or TAK-426 adjuvanted with aluminum hydroxide. The Zika virus vaccine is being tested to provide safety and immunogenicity data to enable the vaccine to be further developed clinically.

Ad26.ZIKV.001 is a replication-incompetent human adenovirus serotype 26 (ad26) vector vaccine candidate. In the phase 1 clinical trial, researchers found two doses of Ad26.ZIKV.001 was safe, causing mild to moderate reactogenicity and induced persistent neutralizing antibody responses. The single dose had lower peak antibodies but was durable after one year. 

mRNA-1893 contains an mRNA sequence encoding for the structural proteins of the Zika virus.

ZPIV is a Zika virus vaccine candidate that consists of a purified formalin-inactivated Zika virus.

INO-A002 is a DNA-encoded monoclonal antibody (dMAb™) technology.

VLA1601 is a purified, inactivated, whole Zika virus vaccine candidate adsorbed on aluminum hydroxide.

VRC5283 is a Zika Virus DNA Vaccine composed of a single closed-circular DNA plasmid-encoded with wild-type precursor transmembrane M and envelope proteins from the H/PF/2013 strain of ZIKV.

Zika Vaccine News For 2017 - 2022

August 4, 2022 - The Journal of Infectious Diseases published an Original Article: Why does Zika virus persist in the semen of some men but not others? 

June 8, 2022 - A RESEARCH ARTICLE - Mosquito saliva enhances virus infection through sialokinin-dependent vascular leakage - The transmission of the virus from mosquito to vertebrate skin constitutes an important bottleneck that is a critical step for viruses to overcome. Factors that provide a replicative advantage for viruses at this key stage of infection are key for defining the overall outcome.

January 27, 2022 - The peer-reviewed journal NPJ Vaccines published: Efficacy of an inactivated Zika vaccine against virus infection during pregnancy in mice and marmosets. 'These proof-of-concept studies demonstrate that ZPIV’s protective efficacy is both potent and durable and has the potential to prevent the harmful consequence of ZIKV infection during pregnancy. Importantly, neutralizing antibody titers correlated with protecting dams and fetuses against ZIKV infection. '

December 9, 2021 - The U.S. CDC issued a Level 2 Travel Advisory for Uttar Pradesh, India.

November 7, 2021 - Researchers at the Institute of Medical Sciences in Banaras Hindu University have reported an important finding on Zika virus pathogenesis, which they claim, will be helpful in understanding the molecular pathogenesis of the virus and in therapeutic development.

June 4, 2021 - Both the mouse and NHP challenge models were further standardized and refined by the ZIKAVAX consortium. "Based on the results, one of the vaccine candidates was selected for evaluation in NHP challenge studies for immunogenicity and efficacy, in comparison to a control vaccine and a first-generation MV-ZIKV vaccine," explains Frédéric Tangy, director of Research at the French National Centre for Scientific Research and head of the Viral Genomics and Vaccination Unit at Paris' Institut Pasteur. "Following the promising results in the preclinical animal models, the selected vaccine candidate was transitioned to further clinical development," adds Roger Le Grand, director of the IDMIT research department.

May 18, 2021 - The Lancet published a study that concluded: TAK-426 was well tolerated, with an acceptable safety profile, and was immunogenic in both flavivirus-naive and flavivirus-primed adults. Based on the safety and immunogenicity profiles of all TAK-426 doses assessed, the 10 μg TAK-426 amount was selected for further clinical development.

May 18, 2021 - The Lancet published a commentary on Zika vaccines: can we solve one problem without creating another? As viable Zika and dengue vaccines are made, it becomes crucial to understand how Zika and dengue immune interactions will affect subsequent flavivirus outbreaks and the use of Zika and dengue vaccines.

March 22, 2021 - Research study: Single-dose of a replication-defective vaccinia virus expressing Zika virus-like particles is protective in mice.

February 18, 2021 - The Center for Infectious Disease Research and Policy at the University of Minnesota, the University of Texas Medical Branch, an expert team of task force members from around the world, and the World Health Organization have developed a draft Zika virus (ZIKV) Research and Development Roadmap. The roadmap is a vital component of the WHO's R&D Blueprint, a global strategy and preparedness plan that allows the activation of R&D activities in advance and during epidemics.

February 16, 2021 - The Zika virus candidate, Ad26.ZIKV.001, a replication-incompetent human adenovirus serotype 26 (ad26) vector, showed promising safety and immunogenicity in phase I clinical trial. Researchers say the vaccine warrants further development should the need reemerge.
