The hepatitis C virus (HCV) is so common that it infects approximately 0.7% of the world population to ultimately cause ~300,000 deaths each year. Small molecule-based antivirals can cure most HCV infections, but these are often only used after irreversible liver damage has already occurred, prohibitively expensive, and inaccessible for high-risk populations.
Jiangsu Recbio Technology Co. Ltd. released phase II data showing its recombinant two-component COVID-19 vaccine Recov appeared more effective than Comirnaty (tozinameran), the mRNA vaccine developed by Biontech SE and Pfizer Inc., as a booster for users of inactivated vaccines.
Eleven vaccines have now been approved by the World Health Organization for preventing COVID-19, but all exhibit drastically reduced activities after 6 months. Unlike vaccines that express only the spike protein as the immunogen, live attenuated vaccines have the potential to confer a broader and more durable protection.
Ethris GmbH has entered into a collaboration with Diosynvax Ltd. to jointly develop a protective mRNA vaccine candidate against a broad range of betacoronaviruses utilizing the company's highly differentiated mRNA modification and design technologies as well as its lipidoid nanoparticle (LNP) and stabilization platforms.
Eurocine Vaccines AB has reported findings from preclinical studies evaluating its mRNA and protein technology platforms for its therapeutic herpes simplex virus type 2 (HSV-2) vaccine candidates. Initial results from the study, comparing the two technology platforms at multiple doses, demonstrate that the mRNA and the protein vaccines were well tolerated and generated T-cell and antibody responses.
Everest Medicines Ltd. has achieved a preclinical proof-of-concept milestone for its mRNA rabies vaccine program. This new vaccine candidate for rabies post-exposure prophylaxis was developed in partnership with Providence Therapeutics Holdings Inc. utilizing a clinically validated mRNA technology platform.
Currently, most patients with urinary tract infections (UTIs) require long-term antibiotic treatment, which poses risks of resistance development and alters the patients' microbiota. Therefore, vaccines that raise safe, effective and long-lasting immune responses across populations for UTI prevention constitute a critical medical need. However, developing such vaccination strategies remains challenging because the responses need to be specific to a broad range of UTI-causing bacteria and include both blood and mucosal responses in the urogenital tract.
Vaxxas Pty. Ltd. raised AU$34 million (US$23 million) to advance its needle-free COVID-19 vaccine program, which began in early November, and readouts from the study are expected in late February or early March, Vaxxas CEO David Hoey told BioWorld. The COVID-19 vaccine patch is based on the company’s high-density microarray patch technology that delivers Hexapro, a second-generation version of the spike protein used in all major U.S.-approved COVID-19 vaccines.
China recently approved four COVID-19 vaccines for emergency use in a span of two days. The nods were granted to Clover Biopharmaceuticals Ltd., Sinocelltech Group Ltd., Beijing Wantai Biological Pharmacy Enterprise Co. Ltd. and Westvac Biopharma Co. Ltd. There is still no mRNA vaccine approved in the country.
