Right. There are around 100 vaccines in development. We have vaccines that have created binding antibodies in primates already. We have some that have been given to humans and produced antibodies as well.
Even pessimistically assuming 90% fail, you end up with 10 vaccines.
Yes, but with each trial stage a particular vaccine candidate passes, its likelihood of failing the further stages goes down. Most candidates that are going to fail, do so in the lab or in Phase 1 trials. A vaccine candidate that passes Phase 1 and Phase 2 has a pretty good outlook.
