From the horror stories i have heard of test patients, there will have to be a long history of extremely low risk before i will even think of trying it.
Further, they aren't testing whether this vaccine will stop one from getting the Wuhan-flu, they are only testing whether it lowers the symptoms one gets. This is not a vaccine test. This is not a vaccine.
Even further, the stuff that is already known to be bad is in this vaccine. So, settled science says stay away from this stuff. (and the pharma-companies know this, that is why they have indemnity from being sued)
