I gave prevnar13 Subcut instead of IM

I grabbed the wrong need and gave the vaccine with a 5/8 inch. I've felt horrible allll day because of it and couldn't even eat lunch. This was to an adult male and I didn't realize it until after the patient left when I had a random flashback of the injection.

What do you think are the chances of an adverse reaction? Necrosis?
Most likely he will simply not develop immunity. A conscientious nurse would contact him and have him come back in for titers and another vaccine.
