This is just my best guess, but...

How, exactly, is that one RN going to supervise several amateurs giving shots? I mean, if this was not a highly contagious respiratory disease, the process could be simple: line 'em all up in a gym or something, have a crash cart ready just in case, and start innoculations.

But with THIS disease, we're supposed to keep 'em separate. So...how do we do that? Set up temporary barriers between stations? Then the nurse can't see what's going on. And you still have shared air in that large space.

Or maybe it doesn't matter - I mean, shared air in a large space isn't very different from the air-sharing that would happen when many people, one after the other, share the air of a small office, right?

Think of it this way; training you how to insert and turn the key to a car is NOT teaching you all of the knowledge and skills that you need to drive. The injection is the easy part. How to deal with reactions and how to diagnose situations where you shouldn’t inject is years of nursing school.

This makes sense to me. I asked my boyfriend, who’s an emergency room RN, and he said this:

Because if something happens to that person taking the injection, the nurse has the necessary medical training to intervene. That’s why we are BCLS and ACLS [basic/advanced cardiac life support] certified. Insulin is made up of hormones and has a much less opportunity to cause an allergic reaction. What people don’t know will hurt them. It’s not about merely knowing how to inject a needle.

Vaccinations are made up of many chemicals that a person has an opportunity to be allergic to. If they go into an anaphylactic shock, they will be fucked. That’s why after you receive an injection, you’re supposed to wait 30 minutes to make sure the allergic reaction does not occur.

Every person who has had an allergic reaction so far to the vaccinations has had a severe reaction causing them to have to receive epinephrine and CPR.

When nurses or other medical professionals get covid, they have to go into isolation for 2 weeks. That’s what is exasperating an already lack of nurses able to administer the vaccine

During the aids pandemic there may have been a shortage of nurses, but as far as I know, the ones who were available weren’t also going into quarantine for 2 weeks.

In the county I live in, Public Health nurses are administering the vaccine, nurses who work in clinics and hospitals are bogged down with patients.

they don't but this is another example of trump not planning and causing death in our country

Insulin is just sub dermal needles, like Bill Bar, just a little prick.
Covid shots go deep into the muscle, and not nearly so easy to do it yourself.
We should train more nurses, free education, and offer citizenship to nurses all over the world.
Most of the nurses I know are Filipino and great at their work.
