Revisit with me the picture Dr. Martin Friede (WHO) painted seven long years ago concerning jet-gun devices (emphasis mine):

CHAIRMAN EDMISTON: You represent sort of the pragmatic perspective here, Dr. Friede. You’re out there in the field. If industry met that benchmark of less than 10 picoliters, would that give you a sense of assurance that we’re moving in the right direction, especially if we evaluate the risk versus benefit component.

DR. FRIEDE: Okay. Let’s just imagine the situation. We have a device, again this famous device X, and it’s actually transmitting 5 picoliters per injection. That’s less than 10. And we know that we’re in a room with 50 percent chronic carriers, and they’re all looking very yellow. And we all have to stand up and we have to inject the person standing next to us and then inject ourselves.

How many people here are going to do that, especially if there was another device that was undetectable using the most sensitive assay, absolutely undetectable?
So for me putting a number and saying five or less than ten, this is not relevant. It must be undetectable using the most sensitive assays that we have.

Because if you can detect blood on it, then there is a risk. That risk might be, as Dr. Kane mentioned, you know I presented the worst case scenario and we should also be looking at the best case scenario. But we are going to have a recommendation to people to use a device. And if we know that that device, we say oh yes, use it, it does transmit blood but not a lot. Don’t worry about it. I’m not comfortable with that. I think we have to say there is no detectable —

[He’s interrupted.]

Dr. Martin Friede, Ph.d., Initiative for Vaccine Research, World Health Organization, seems to be one of the good guys.  To help more people, we need to identify allies and potential allies in many fields of study.
