I would be very curious to know if the team received any kind of pressure to stop what they're doing or if they will communicate if such thing would happen. Don't want to sound cynical, I just watched a lot on the subject recently and it seems there's a huge industry behind having a lot more benefits (material ones) from the actual sick people and their life-long expensive treatments compared to a vaccine.
Even if it doesn't work God bless to you all for trying this. It's a wonderful thing to get you up in the morning.
