VANCOUVER, BC, Oct. 20, 2021 /CNW/ -- BioVaxys Technology Corp. (CSE: BIOV), (FRA:5LB), (OTCQB:BVAXF) ("BioVaxys" or "Company"), announced today that it has filed with the United States Patent & Trademark Office ("USPTO") a provisional patent application for its haptenized viral antigen vaccine platform to elicit a broad cross-reactive immune response against most or all sarbecoviruses, the family of Coronaviruses that includes SARS-CoV-2, which causes Covid-19.
A recent study1 published in the New England Journal of Medicine ("NEJM") evaluated human volunteers who had natural immunity to SARS-Cov-1 (a coronavirus similar to SARS-CoV-2 but with higher mortality), which broke out in 2003 and is often referred to as the first global pandemic of the 21st century2, and who were immunized against SARS-CoV-2 with a widely used mRNA vaccine. The result was surprising: the recipients had neutralizing antibody not only to SARS-CoV-1 and SARS-CoV-2, but also to eight other sarbecoviruses, including emerging zoonotic sarbecoviruses that may have future pandemic potential. This cross-reactivity was due to similarities in the S-spike protein. Sarbecoviruses, such as SARS-CoV-1 and SARS-CoV-2, all bind to the ACE2 receptor, which makes them highly transmissible.
Biovaxys intends to leverage its haptenized viral protein vaccine platform to induce immunity against all or most sarbecoviruses by immunizing people who have convalesced from a documented Covid-19 infection, or received a full course of any Covid-19 vaccine recognized by the World Health Organization, with a novel vaccine composed of the dinitrophenyl ("DNP")-modified S-spike protein of SARS-CoV-1.
Dr. David Berd, Chief Medical Officer of BioVaxys, commented: "Scientists dream of a pan-Coronavirus vaccine that would protect the population against any SARS-like respiratory virus that might mutate and emerge from a wild animal in the future. Our approach could constitute a pan-sarbecovirus vaccine that would protect humans against a very dangerous subgroup of Coronavirus that could emerge from the wild and cause as much devastation as Covid-19."
James Passin, Biovaxys Chief Executive Officer, stated, "There have been over 217 million recoveries following confirmed cases of Covid-19 (www.statista.com) and 6.6B doses have been given of Covid-19 vaccine (Bloomberg Oct 15 2021); this total target population of almost 4 billion people represents a massive commercial opportunity for proposed our pan-sarbecovirus booster vaccine, which has the potential to confer cross-reactive neutralizing antibodies, not only against all Covid-19 variants, but future emerging dangerous zoonotic sarbecoviruses."
For greater certainty, BioVaxys is not making any express or implied claims that it has the ability to treat the SAR-CoV-2 virus at this time.
