Roger Koops used to work in vaccine development. Here's why he doesn't plan to get the Covid-19 shot

I speak with retired chemist Roger Koops, about his experience working in vaccine development. We talk about some misunderstandings about how vaccines work, and some of his concerns about the Covid-19 vaccines.

Roger Koops is a contributing author for AIER, and is also a retired scientist, with a PhD in chemistry and over 25 years in the pharmaceutical and biotechnology industries. He has authored or co-authored several papers on pharmaceutical technology and chemistry.

Our previous conversation, about masks and viruses, is here.

His article, "A Primer for the Media on Viruses, Vaccines, and Covid-19" is here.
