Come on, people. This is pretty typical technology. It's a self-retracting needle syringe.
I have at least 20 of those at home and used them myself once per week. When you give the injection, as the plunger hits the bottom of the chamber, the needle springs back into the syringe. That keeps people from accidentally sticking themselves or others with the sharp needle. No more need for "sharps" containers for needle disposal. It's in the plastic casing of the syringe.
Later, if I look into the syringe casing (or shake it)... I can hear the needle rattling around. It happens so fast that it looks like the needle disappears. In reality, it retracts so fast you don't even feel it.

That was a big needle for a vaccine and it unged all the way in.
Agreed. Needle looks too long for an injection into the deltoid.
