Researchers from Pritzker Molecular Engineering, under the guidance of Prof. Jeffrey Hubbell, demonstrated that their compound can eliminate the autoimmune response linked to multiple sclerosis. Researchers at the University of Chicago's Pritzker School of Molecular Engineering (PME) have developed
The creators call it an inverse vaccine. A vaccine causes the immune system to recognize a compound to attack. This treatment causes the immune system to ignore a compound it had previously recognized. So they are specifically saying it’s not a vaccine (and OP is misrepresenting them), even though that word is in the phrase, something roughly like antivenom is not a venom.
