FOX Nation host Abby Hornacek takes a closer look at the topics and buzz words you find your friends and coworkers using to sound intelligent. Each week Abby and her expert guests will tackle topics we take for granted and help to explain the roots and meanings behind them.

This week, Former FDA Associate Commissioner Peter Pitts joins Abby in the classroom to help with her lesson plan. Peter explains what vaccines are, how they are developed, how they approved and brought to market, and how they work in the body. Plus, Peter discusses what we can expect from a COVID-19 vaccine.
