Variants, Vaccine Efficacy, COVID long haulers… A review of what we know

 

 

Dr. Ramchandani discusses the difference between a variant and a mutation, the efficacy of the COVID-19 vaccine on these variants, and COVID-19 as well as what COVID-19 long haulers experience.  Its sobering to know that 500,000 people have died from COVID-19.  Thats more than all the recent wars that the US has fought including WWII.
