Anthony Fauci warns of possible antibody dependent enhancement (ADE) with vaccination

"Does the vaccine make you worse? And there are diseases in which you vaccinate someone, they get infected with what you're trying to protect them with, and you actually enhance the infection. You can get a good feel for that in animal models. So that's gonna be interspersed at the same time that we're testing, we're gonna try and make sure, we don't have enhancement. The worst possible thing you can do, is vaccinate someone to prevent infection and actually make them worse."
