A shift in focus is needed to tackle COVID-19

Since the identification of SARS-COV-2, the virus which causes COVID-19, there has been a surge in funding of research and testing to find a vaccine and treatments, with unprecedented collaboration and openness between researchers worldwide.

In addition to use of advanced technologies more relevant to humans, such as patient cultures, artificial intelligence and organ-on-a-chip technology some researchers are using animals, including mice, ferrets, primates, guinea pigs, pigs and cats in the UK, US, Netherlands, China and Australia.

The World Health Organization-China Joint Mission has advised that the “ideal animal model for studying routes of virus transmission, pathogenesis, antiviral therapy, vaccine and immune responses has yet to be found”, and yet significant funding and precious time is being spent on animal research. This is despite the known species differences which make the results from such data unreliable when translated to humans.

For example, mice are one of the most commonly used species in drug and vaccine research. In addition to major differences between human and mouse respiratory systems, species differences specific to research for SARS-COV-2 include that mice do not naturally have the same receptors the virus uses to infect human cells. Researchers are now attempting to “humanize” mice to ensure they contract the virus. Such fundamental differences risk impeding the production of vaccines and other treatments to help prevent and reduce the symptoms of COVID-19 in people.

While time, resources and efforts are being put into attempting to find the “ideal” animal model, advanced non-animal scientific methods, which relate directly to the disease in humans, are being progressed. These sophisticated research methods have the potential to deliver safer, more effective vaccines and treatments to the market more quickly but need more funding and support.

Advanced techniques include mathematical modelling of transmission and size of the epidemic; the use of patient lung fluid cultures to study the virus genome; patient biopsy samples to investigate lung tissue damage; artificial intelligence models to predict which drugs could treat COVID-19; using antibodies from COVID-19 survivors to treat patients; human organ-on-a-chip technology emulating human lung infection for drug discovery; organoids to investigate how the disease infects human tissue; and in vitro 3D human airway cell models for evaluating drugs.

The undersigned scientists, academics, organizations and concerned parties urge the World Health Organization, national governments, funding bodies, regulators, and the scientific community as a whole to prioritize funding and resources for advanced non-animal scientific methods to accelerate the path to finding effective vaccines and treatments for SARS-COV-2 and, going forward, for other human diseases.
