Welcome in!  Sorry for the delay on this episode, it was supposed to air over a month ago before the COVID-19 vaccine was available.  After we had to sit out 2 weeks due to a positive test it was time for the Christmas shows to be released.  So here it is!  In this episode we will talk about the history of vaccinations, the different types of vaccines and how they work on a basic level, and discuss new and recent developments including mRNA vaccines.  Today's WoTR quiz word is "spy".  Enjoy!
