Sorry, no need for an apology.
One of the reasons why I'm optimistic regarding a vaccine is that there are multiple vaccine programmes in different countries. That's got to increase the odds of a result.
All the political leaders need to do is to ensure the laws permit & encourage acceleration of validation programmes, without unreasonable risks.
So if that means much larger trial sizes than normal, deliberately infecting volunteers who have had the vaccine (starting with the lower risk groups) and so on, then do it.
For the avoidance of doubt, if I had antibodies from a vaccine, I would have no problems personally volunteering for exposure to the virus.
