#97 – Peter Hotez, M.D., Ph.D.: COVID-19: transmissibility, vaccines, risk reduction, and treatment
Summary

The Drive podcast, hosted by Peter Atia, features an episode where renowned vaccine scientist Dr. Peter Hotez discusses the COVID-19 pandemic. They talk about the difference between the virus (SARS CoV-2) and the disease (COVID-19), how it spreads, where it came from, what we know and don't know about it, potential treatment options, and why a vaccine is unlikely in the near term. The virus is highly transmissible and lethal, making it a serious global health threat. Certain groups, including individuals over the age of 70 and those with underlying disabilities, are at a higher risk of serious illness, and healthcare workers are also at risk.

The lack of diagnostic testing in the US has allowed the virus to circulate for long periods of time, potentially leading to a shortage of healthcare workers and first responders. Social distancing is crucial to buy time, but the opportunity to prevent the virus from entering the country or reaching a sufficient number of the population seems slim. Convalescent serum could be a low-cost intervention that can be applied right now by identifying patients who have been infected and recovered, collecting their serum, isolating the antibody, and using it as a treatment or prophylaxis.

The podcast also discusses the development of a potential vaccine for the current coronavirus outbreak. The vaccine was originally developed for the SARS virus in the early 2000s, but due to lack of funding, it was not tested in clinical trials. However, with the emergence of the current coronavirus outbreak, the vaccine is being reconsidered for repurposing. The article also discusses the ACE2 receptor and its role in the virus's ability to infect cells, as well as the various modes of transmission for the virus. The article emphasizes the need for funding to move the vaccine into clinical trials and highlights the challenges of developing vaccines for emerging diseases.

Dr. Hotez expresses concern about the impact of the virus on older populations, particularly those in nursing homes, and the lack of guidance being issued around nursing homes and assisted living facilities. He discusses the vulnerability of urban areas and the potential for hospital beds to fill up quickly. He suggests implementing new antibody therapy to offer hope to those affected by the virus. Dr. Hotez acknowledges the difficulty in predicting the spread of the virus and the limitations of models. He believes that a modest change in assumptions of what goes into the model can often have huge differences. Overall, the podcast provides valuable insights into the current COVID-19 pandemic and the challenges faced in developing effective treatments and vaccines.
