Critically Speaking

Jan 6, 2021

In this episode, Therese Markow responds to questions from two listeners.  One listener asked why some vaccines are good for life while others have to be administered annually.   Another listener asked if some people have a natural inborn immunity to COVID.  In addition to addressing these questions, she also emphasizes the importance of basic scientific research and why it is imperative that scientists from around the world freely share their information with one another. 


 Key Takeaways:

  • The types of viruses and their mutations affect the type of vaccine that we get and how often we need to get it. 
  • Because the COVID-19 virus is so new, we do not have enough information to fully understand the whys and hows of virus action.
  • In all cases a virus must enter the cell in order to replicate and cause illness.. Mutations in the viral genome can enhance or prevent the virus from entering. 


"We have to do our part to minimize the risks." —  Dr. Therese Markow
