MADISON, Wis. – An international collaboration of virologists at the University of Wisconsin-Madison and the vaccine companies FluGen and Bharat Biotech has begun the development and testing of a unique vaccine against COVID-19 called CoroFlu.
CoroFlu will build on the backbone of FluGen’s flu vaccine candidate known as M2SR. Based on an invention by UW-Madison virologists and FluGen co-founders Yoshihiro Kawaoka and Gabriele Neumann, M2SR is a self-limiting version of the influenza virus that induces an immune response against the flu. Kawaoka’s lab will insert gene sequences from SARS-CoV-2, the novel coronavirus that causes the disease COVID-19, into M2SR so that the new vaccine will also induce immunity against the coronavirus.
Refinement of the CoroFlu vaccine concept and testing in laboratory animal models at UW-Madison is expected to take three to six months. Bharat Biotech in Hyderabad, India will then begin production scale-up for safety and efficacy testing in humans. CoroFlu could be in human clinical trials by the fall of 2020.
Four Phase I and Phase II clinical trials involving hundreds of subjects have shown the M2SR flu vaccine to be safe and well tolerated. This safety profile, M2SR’s ability to induce a strong immune response, and the ability of influenza viruses to carry sequences of other viruses make M2SR an attractive option for rapidly developing CoroFlu as a safe and effective SARS-CoV-2 vaccine.
“We are going to modify M2SR by adding part of the coding region for the coronavirus spike protein that the virus uses to latch onto cells and begin infection,” says Gabriele Neumann, a senior virologist in Kawaoka’s lab and co-founder of FluGen. “CoroFlu will also express the influenza virus hemagglutinin protein, which is the major influenza virus antigen, so we should get immune responses to both coronavirus and influenza.”
M2SR is a unique form of the flu virus. It lacks a gene called M2, which restricts the virus to undergoing only a single round of replication in cells.
“The single replication means the virus can enter the cell, but it can’t leave,” says FluGen co-founder, president and CEO Paul Radspinner. “So, in essence it tricks the body into thinking it’s infected with flu, which triggers a full immune response. But since it can’t replicate further, you don’t get sick.”
CoroFlu, like M2SR, will be delivered intranasally. This route of administration mimics the natural route of infection by coronavirus and influenza and activates several modes of the immune system. Intranasal delivery is more effective at inducing multiple types of immune responses than the intramuscular shots that deliver most flu vaccines.
The Kawaoka group will insert genetic sequences from SARS-CoV-2 into M2SR and then assess CoroFlu’s safety and efficacy in animal models at UW-Madison’s Influenza Research Institute. The institute has a high-level biosafety facility designated Biosafety Level 3 Agriculture with the ability to safely handle and study pathogens like highly pathogenic influenza viruses and the novel coronavirus.
M2SR was developed by FluGen and includes technology exclusively licensed through the Wisconsin Alumni Research Foundation (WARF), which manages patents for UW-Madison. “To confront a global challenge, this is collaborative discovery at its best,” says Erik Iverson, CEO of WARF. “The partners in this endeavor — University of Wisconsin researchers, a biotech startup, and an international vaccine developer — are moving forward with a sense of urgency and integrity incumbent upon us as scientists and world citizens.”
Bharat Biotech has commercialized 16 vaccines, including a vaccine developed against the H1N1 flu that caused the 2009 pandemic. FluGen will transfer its existing manufacturing processes to Bharat Biotech to enable the company to scale up production and produce the vaccine for clinical trials. Bharat Biotech will manufacture the vaccine, conduct clinical trials and prepare to produce the vaccine for global distribution. Bharat Biotech can produce almost 300 million doses per year.
“The core mission of Bharat Biotech is to apply innovative technologies in addressing the healthcare concerns of the developing world and to provide them with affordable, high quality vaccines and therapeutics,” says Raches Ella, head of business development for the company. “Ninety percent of our vaccines are sold in lower middle-income countries with affordable pricing being core to our business model. We will fervently work toward the successful development of an efficacious COVID-19 vaccine.”

About FluGen, Inc.
FluGen, Inc. is a clinical stage vaccine company focused on improving the breadth and effectiveness of influenza vaccines. The company’s technology comes from the laboratory of Dr. Yoshihiro Kawaoka at the University of Wisconsin-Madison. FluGen’s lead product candidate, M2SR, is a universal flu vaccine which is based on the knowledge that a natural or wild-type flu infection prevents people from being infected in subsequent years. The M2SR vaccine has demonstrated a robust immunology profile that works through multiple immune pathways systems and appears to convince the body it has been infected, triggering a robust immune response while not displaying flu symptoms. Human efficacy studies have shown that M2SR can protect against mismatched strains of Influneza. For more information about FluGen, Inc., please visit http://www.FluGen.com.
