What are the dangers of this?

Question

a friend went to get a vaccination yesterday and she told me that she noticed that the syringe had a bit of air in it. but before she could say anything, the procedure was over. she now says that her arm hurts a little. what are the dangers of having a bubble in the syringe tube and having the bubble inected into you?

Answer 1

Nothing.  A vaccination doesn't even go into your veins, it goes into either the muscle or the fat in the back of your arm.  There is danger in injecting a bolus of air right into the vein, but even that is rare.  Especially if it happened yesterday and she's still kickin' then I'm sure she'll live.  Her arm is sore from the injection, and nothing else.

Answer 2

Both previous answers are correct. In addition, her arm hurts from the vaccine -- not from the air bubbles. Whatever she's being vaccinated against is being fought off by her immune system, on a small scale, in her arm right now, which is why it hurts.

Don't worry about it!

Answer 3

nothing, it's takes a lot more than a little air bubble in a syringe to kill you

Answer 4

If she is alive today, none.

Vaccinations dont go straight into veins, and an air bubble that would do any harm would have done it by now.
