No. He has no studies. He has one anecdotal case where he thinks that is what happened. He is then referring to the mice cases but he has not looked at those studies and so he is just guessing that the method, dosage, and impact of giving mice these injections means there is a similar impact in humans. When he talks about the fluid from a fine needle going in with a lot of pressure. That is true but that would decrease rather than increase the chances of something getting in a vein. It will just blow small veins out immediately.Still so sure?
The other thing as I said before. It makes no sense this would be happening more in one portion of the population than the other. For instance, happening mostly in young males. The other thing is that it is happening much less with the first shot in young males than with the second shot. It makes no sense that you would hit a vein more frequently the second time around. The answer is that this is an IMMUNE REACTION. It is no big deal to ask a nurse to aspirate but the dangerous part is to think this will make the problem go away. It will not. While rare this is a side effect of the vaccine and hence the caution by the FDA and manufacturers.
