I understand the Zika virus is linked to GBS. I would think the CDC would test our blood to see if there is a cure/antibody hiding in us.
There are so many different things that can initiate GBS. There would only be a Zika antibody if you had Zika. With the panic over Zika now someone is probably working on some kind of vaccine so they can make some money but I doubt there is any more research into GBS itself. I do hope the publicity might stir up some interest though. I wouldn’t want anyone else to go through this.
