Both of you trolls are doing people a great disservice. Anyone who reads your flippant comments and doesn't take what this immunologist says about the mRNA vaccine seriously have YOU to thank!
Vanderbilt University Medical Center has the premier league of immunologists and virologist in the world. They have been the leaders in Coronavirus for over 20 years now. Even when coronavirus wasn't popular and didn't get any research funding.
They have been the leaders in SARS and MERS viral research. I'll take their word over anybody else. Especially a sacked one.
