Will I get infected for injecting without wiping needle?

Resolved Question:

I was giving myself a B12 injection and cleaned the single dose vial with asceptic technique. After puncturing the vial, I forgot that I didn't put air into the syringe. I pulled out the syringe, put the air in and then re-inserted it without wiping the top again. I then used the syringe to give myself the injection. I am worried. Am I going to get an infection? I have OCD and am REALLY stressing about this.

Thank you for your query at
No. You will NOT get an infection.
Frankly, the same thing has happened with me quite a few times, and never any infection, not even a single time.
You need to stop stressing because you had already cleaned the vial at least once. It would have remained uncontaminated even while you re-inserted the needle.
Please stop worrying!
