If he is insistent then you must watch Dr John Campbell's video clips where he talks of the method of injection which is especially relevant for the young and fit
I have posted this so many times this has got to be the last, if people want knowledge they must research or suffer
There are three main types of injection depending on the design of the drug
This vaccination is to be put into the muscular part of the shoulder, never the blood vessels
So to achieve that medical people have been taught for many years at "aspirate" as they inject
IE you push the needle in and then withdraw the plunger slightly to observe for the presence of blood (which indicates you have hit a vessel) if blood is present you throw the needle away and start again
Early on WHO put a directive out that you should not aspirate === (this is bureaucrats overturning long standards of medical procedure) they say they were concerned that if they had too many double injections ( which hurt) people would complain and the rate of the vaccine rollout would slow.
So to hell with medical standards as long as every one gets the jab
There is a researcher doing a study to discover what the ratio of blood vessel to muscular is as there are no figures and medical people guesses range from one in thirty to one in a hundred
The theory at the moment is strong fit young men are especially at risk due to being fit their blood vessels in the arm are larger due to the exercise routines they engage in
This is my opinions from my research and I am not a medical person PLEASE DYOR
