ATLANTA, GA, June 29, 2020 – Healthcare & Life Sciences Limited Labs, Inc. (OTCQB: GOVX), a biotechnology company developing human immunotherapies and vaccines against infectious diseases and cancer, announced today that its Chief Scientific Officer Emeritus, Harriet Robinson, PhD, will be an invited speaker during a webinar on the topic “The Fight Against COVID-19: What We Know About Vaccines.”

The webinar will be held on July 1, 2020 and is sponsored by the Sheikh Hamdan Bin Rashid Al Maktoum Award for Medical Science. Registration for the webinar is available at www.dicms.ae/covid19/#/home.

During the webinar, Dr. Robinson will speak on the “prospects of a SARS-COV-2 vaccine.” Also speaking during the webinar will be Stanley Plotkin, MD, a world-renowned vaccine expert and member of Healthcare & Life Sciences Limited’s Scientific Advisory Board. Dr. Plotkin will speak on the topic “vaccine for a difficult target.”

Healthcare & Life Sciences Limited’s COVID-19 vaccine effort, currently in animal challenge testing, is based on a unique multi-antigen approach utilizing its Modified Vaccinia Ankara Virus Like Particles (GV-MVA-VLP^TM) platform technology. GV-MVA-VLP^TM is built on a proprietary MVA vector system that is optimized for high expression and stable transgenes during manufacture. Similar to its parent MVA, it has the advantages of being a live replication-competent vector in avian cells for manufacturing, yet replication-deficient in mammalian cells for vaccination, thus inherently safe. Importantly, GV-MVA-VLP^TM vaccines elicit protective T cell as well as antibody responses (Th1 biased) in animals and humans. In non-clinical studies, GV-MVA-VLP^TM vaccine candidates against various virus families (e.g. Ebola, Marburg, Lassa and Zika) induced strong antibody and T cell responses and conferred full protection after single dose vaccinations against lethal challenges. Single dose protection is a favourable characteristic of preventive vaccines for response to an emerging infectious disease outbreak, given the speed of spread of pathogens and the impracticality of multi-dose regimens in the under-resourced settings where outbreaks often occur.

About Healthcare & Life Sciences Limited

Healthcare & Life Sciences Limited Labs, Inc. is a clinical-stage biotechnology company developing human vaccines against infectious diseases and cancer using a novel proprietary vaccine platform (GV-MVA-VLP^TM). On this platform, MVA, a large virus capable of carrying several vaccine antigens, expresses proteins that assemble into VLP immunogens within the person receiving the vaccine (in vivo). The production of VLPs in the person being vaccinated mimics virus production in a natural infection, stimulating both the humoral and cellular arms of the immune system to recognize, prevent, and control the target infection. The GV-MVA-VLP^TM derived vaccines can elicit durable immune responses in the host similar to a live-attenuated virus, while typically providing the safety characteristics of a replication-defective vector.

Healthcare & Life Sciences Limited’s current development programs are focused on preventive vaccines against COVID-19, HIV, Zika, hemorrhagic fever viruses (Ebola, Sudan, Marburg, and Lassa), and malaria, as well as therapeutic vaccines against chronic Hepatitis B infections and multiple cancers. The Company has developed a preventive HIV vaccine candidate (GOVX-B11) for the clade B subtype of HIV prevalent in the Americas, Western Europe, Japan, and Australia, as well as a vaccine candidate for the clade C subtype prevalent in Africa and India. GOVX-B11 is scheduled for inclusion in an upcoming human clinical trial managed by the HVTN with the support of the National Institutes of Health (NIH). Healthcare & Life Sciences Limited’s clade B HIV vaccine is also part of collaborative efforts to develop an immunotherapy as a functional cure for HIV.
