Some vaccine leaked out during vaccination

Took dcs to boots to have men b vaccine and ds the little wriggler pulled away and the needle came out. The nurse immediately put the needle back in and gave the rest of the dose. Some of the vaccine squirted down his arm, just a couple of drops.
Aibu to think she should have stopped at that point and started a new syringe? I asked and she said it would be fine but I'm not convinced.
Anyone got any knowledge or experience? I've contacted my gp for advice from the nurse and waiting to hear back.

Why clopysow? Genuinely not sure if he will have received the full dose or not so genuinely concerned.

I'm sure it's not a problem. She said it's fine - why would she lie?

If she had got a new syringe, she would have been giving your son more than one syringe's worth. From the sound of it, nearly two doses.

Slightlypanicked Tue 16-Aug-16 13:49:45

All the info I can find online say the needle should be replaced if it comes out and that if any vaccine is lost it should be repeated. I was just a bit concerned as it was only a 1ml vaccine a few drops would have been quite a bit if it

She couldn't start a new syringe as that would be too much, plus you'd have had to pay for it?

ItsLikeRainOnYourWeddingDay Tue 16-Aug-16 13:51:14

Children have two men b vaccs, in some cases hey have three so a few drops will not make any difference. It would have been more dangerous to guess how much to use to repeat the injection

Slightlypanicked Tue 16-Aug-16 13:51:55

I would have paid for it if nessecary mo point in already paying £100 if it's not effective

Slightlypanicked Tue 16-Aug-16 13:52:21

Yeah he's having another in 8 weeks

I'm sure it's fine.

How would starting a new syringe have helped? Either she would have given him a new full dose on top of the part-dose he'd already had (I wouldn't have thought that was a good thing), or she would have had to guess how much to give him from the second syringe (which would likely be no more of an accurate dose than what he's had).

Slightlypanicked Tue 16-Aug-16 13:59:08

Just the advice I read online that's all. I had a look to see if it was OK and everything I could find said the dose had to be redone.

It's fine. On one of the booster injections I didn't hold her other arm tight enough and she managed to grab the syringe out of her arm mid injection. Some was lost but the nurse said it's fine. It's probably not that unusual and there would be guidelines on this kind of thing

carefreeeee Tue 16-Aug-16 14:02:27

As long as most of it went in it'll be fine. The doses aren't that exact anyway

Slightlypanicked Tue 16-Aug-16 14:09:07

Thanks I'm hoping so. I'm assuming nurse at the doctors will say same thing but just so expensive and put ds through having it done I was so disappointed that it could have all been for nothing.

Was it Bexsero?
If so then it's a 0.5mL vaccine. Losing 2 drops will not make a significant difference to the immunogenicity. Overdose is more serious; the medic did the right thing..

LaContessaDiPlump Tue 16-Aug-16 14:13:08

I'll get (approximately) scientific on your ass grin

1 ml = 1000 microlitres, or 1000 ul.

A needle-sized drop, based on my lab experience, is roughly 10-20 ul. You say a few drops were lost, so let's be generous and say 50 ul total.

That leaves 950 ul of vaccine that your son received - 95% of the intended dose. Given that they MUST budget for the occasional spillage, I think that must be more than enough to ensure a sufficient immune response.

Therefore, your son has been given enough vaccine and it should generate an immune response. Even if it doesn't work for some reason, there will be another shot in 8 weeks as a back-up measure!

Do you really want to do it again anyway? He'd have 2 lots of vaccine on board, poor dab. The whole point of vaccinations is to whip the immune system into a frenzy so he'd probably feel quite unwell sad

How old is your 'little wriggler?

foxychox Tue 16-Aug-16 14:15:30

The nurse should report it as an administration error but you could do this yourself if you have the package insert? It shouldn't make any difference to how well it works though.

Slightlypanicked Tue 16-Aug-16 14:25:21

Thank you for getting scientific on my ass grin that helped a lot thank you.
Yes it was bexsero.
The little wriggler is 3 and far too strong for his own my good

LaContessaDiPlump Tue 16-Aug-16 14:28:47

Jolly good, glad to be reassuring grin

Honestly, these things are designed to be immunogenic and so I'd imagine you could probably get a decent immune response in lot of kids (sorry MN, I mean CHILDREN) with half the quantity in the syringe. And as Bombay said, they'd be more concerned about overdose than underdose so a second round of it seems unlikely.

Slightlypanicked Tue 16-Aug-16 14:30:24

Thanks LaContessa I suppose if he gets a high temperature etc later on it must have been enough to cause a response.

JinkxMonsoon Tue 16-Aug-16 14:32:36

Considering how poorly Bexero makes them (I've never experienced having to administer Calpol before a vaccine until that one) then a double dose would definitely be a bad idea.

bombayflambe Tue 16-Aug-16 14:33:04

Well the 0.5mL dose is sufficient for an adult or a tiny 2 month old so there is significant leeway in the units/kilo required to make it work. I think you'll be fine.

YABU for contacting your GP about it for further information/reassurance and wasting their time with non NHS work.
