SAN DIEGO, Nov. 29, 2021 (GLOBE NEWSWIRE) -- Revelation Biosciences Inc. (Revelation), a clinical-stage life sciences company that is focused on the development of immunologic‑based therapies for the prevention and treatment of disease, today announced it has created a scientific advisory board and appointed Catherine Blish M.D., Ph.D., and Paul Spearman M.D. to its scientific advisory board.

Dr. Catherine Blish is a Professor of Medicine and Immunology and the Associate Dean for Basic and Translational Research at the Stanford University School of Medicine. Her research is dedicated to learning how to harness the immune system to prevent and cure diseases. Her lab studies host-pathogen interactions, with a particular focus on innate immune responses to a diverse array of pathogens including HIV, dengue virus, influenza, tuberculosis, and SARS-CoV-2.

She has received numerous awards for research and mentoring, including the Stanford Immunology Outstanding Faculty Mentor Award, the Beckman Young Investigator Award, the Doris Duke Charitable Foundation Clinical Scientist Development Award, the NIH Director’s New Innovator Award, and the NIDA Avant-Garde Award for HIV/AIDS Research. Dr. Blish is an elected member of the American Society for Clinical Investigation and the American Association of Physicians.

“The body’s immune system is incredible and complex,” said Dr. Catherine Blish. “It is our body’s best defense – and offense – for infections including influenza and SARS-CoV-2, which is why we need to identify new and better ways to activate and enhance it. I look forward to working with the impressive team of experts at Revelation to bring new therapies to the people who need them.”

Dr. Paul Spearman is a Professor in the Department of Pediatrics at the University of Cincinnati School of Medicine, Director of the Division of Infectious Diseases and Albert B. Sabin Chair in Pediatric Infectious Diseases at Cincinnati Children’s Hospital Medical Center. His lab studies focus on fundamental aspects of HIV biology and pathogenesis. In addition, he is directing vaccine trials for adults and children, which extends his research beyond HIV to Ebola, SARS-CoV-2 and other pathogens. His team is currently developing virus-like particle vaccines for Ebola, HIV and SARS-CoV-2. Dr. Spearman is a member of the Leadership Group for the Infectious Diseases Clinical Research Collaborative, which aligns with the Division of Microbiology and Infectious Diseases within the National Institute of Allergy and Infectious Diseases.

“The impact of vaccines on the health of children and adults is truly tremendous,” said Dr. Paul Spearman. “The benefits of vaccines are particularly apparent right now as we see the success of COVID vaccines. However, we still have much work to do to develop improved vaccine responses for infectious pathogens. I believe the work Revelation is doing has great potential to improve the protective immune responses to vaccines, and I look forward to being part of the team.”

In 2019, lower respiratory tract infections (LRTIs), including pneumonia and bronchiolitis, affected 489 million people globally. And, during the 2019-2020 season, the CDC estimates that influenza was associated with 38 million illnesses, 18 million medical visits, 405,000 hospitalizations, and 22,000 deaths.

“With Drs. Blish and Spearman, we have added two of the nation’s top infectious disease researchers and practitioners,” said James Rolke, Chief Executive Officer of Revelation. “As we continue to see devastating consequences from respiratory viruses like COVID-19, we are committed to finding new ways to leverage the body’s immune system to prevent and fight these infections.”

About Revelation Biosciences Inc.

Revelation Biosciences, Inc. is a clinical stage life sciences company focused on the development of immunologic-based therapies for the prevention and treatment of disease.
