Is Justin Trudeau really vaccinated?

I recently heard a rumor about Canadian PM Justin Trudeau faking his COVID-19 vaccination. So I searched for some clues.

COVID-19 vaccine is given by IM(intramuscular) injection. First, let's see how to do IM injection. You can find the following videos on Youtube:

Intramuscular(IM) injection - OSCE Guide

The video instructs to apply gentle traction below the injection site, to increase deltoid muscle thickness.

Let's see another video:

Deltoid Intramuscular injection - Everything You Need To Know - Dr. Nabil Ebraheim

This video instructs to squeeze deltoid muscle to increase thickness and avoid nerve injuries.

Now, it's time to see Justin Trudeaus's COVID-19 vaccinations. He received 2 doses and a booster:

Canadian PM Trudeau Receives First Dose of AstraZeneca's COVID-19 Vaccine

Interestingly, the nurse use only one hand, without touching Trudeau's deltoid muscle.

Trudeau receives Moderna COVID-19 vaccine for 2nd dose

Prime Minister Trudeau gets COVID-19 vaccine booster shot

The videos of 2nd dose and booster show the same injection "technique". It's like throwing a dart to his shoulder.

Browsing through many other IM injection videos, I find Trudeau's injection videos are not like the others.

I asked a registered nurse about this, and she says nobody gives IM injection like that. I don't know, maybe this is a brand new technique and she doesn't know about it.
