Hear me out, measles can cause immune system amnesia. People with autoimmune disorders have immune systems that want to kill them. What if we use the immune system amnesia property of measles to reset the immune system of people suffering with autoimmune disorders? Maybe we could do some crispr on the measles virus to make it not as dangerous or something like that first though.
This sounds like the kind of thought an antivaxer would have to justify why they don’t actually need vaccines. They are just resetting their immune system with this one simple hack called “being infected”.
