Did I "Kill" My Moderna Vaccine?

[kyphysics]

VERY DUMB QUESTION:

Could I have "killed" my Moderna vaccine (or its efficacy)? I got a Moderna shot at 9AM today. At 10:45, the band aid "rubbed off" my arm when I was doing some moving around. I looked at the wound site and it was just a tiny pink "bump." No bleeding that I could tell. I threw away the band aid and just wiped the entire arm area with rubbing alcohol (to clean it).

THEN, I thought, oh wait! ...Could that rubbing alcohol have "seeped" into the shot site/wound and into my body and killed the vaccine or made it less efficacious? I know nothingn about biology/medicine, so forgive me if this sounds like a super dumb question.

I was thinking/hoping that the vaccine had already gotten into my blood stream and wouldn't just be "sitting there" collecting around the shot site. I figured it would be "circulating" throughout my entire body by now (again, it was 1.5-ish hours later...1 hour 45 min. to be exact since the shot)...I figured it I had IMMEDIATELY wiped the shot site with rubbing alcohol (say within minutes of the shot), perhaps that might mess up the vaccine...but would this time gap of 1 hour/45 min. be enough such that wiping the shot site with alcohol and throwing away the band aid (it's still off right now) wouldn't affect the vaccination process?

There's a study on that very issue:

We can't give advice here. If you're worried it's best to see your doctor and ask or even the place where you got the shot.

The bandaid is usually there to prevent infection and to prevent your clothes from getting stained by any oozing blood. The article mentions that a day or so is long enough.

I believe the vaccine dose which is pretty small was already absorbed by your body into the muscle tissue.

But, those patients had band aids on after SKIN SURGERY, no?

If so, that seems very different from getting a small shot in the arm. I would think a surgeon cutting up my skin might require a longer time to keep the band aid on and perhaps the advice wouldn't generalize to regular vaccine shots?

What happened to talking to your vaccine provider or the doctor?

Any further discussion will result in giving medical advice and so it's best to close this thread now.

The intramuscular (IM) injection leaves the vaccine dose well down in your deltoid muscle tissue. Topical cleaning an hour later should have no effect. If still in doubt, message your healthcare team (does your medical plan have a website that you sign into? if so, you should be able to ask a question via a message there).
