Chadi is joined by Priya Sampathkumar (@PSampathkumarMD), MD, infectious disease specialist and hospital epidemiologist, Mayo Clinic, to detail the COVID vaccine effort over the past 12 months and how the currently approved ones came to be safe and effective in such a short period of time. She then compares each vaccine in relation to their clinical trials and study populations, side effects (including some rare ones), and efficacy. Chadi and Dr. Sampathkumar converse on what it will take for herd immunity to be reached in the US, how worried we should be about the virus variants, proper precautions to be taken after vaccination, and so much more.
