Another chicken pox one - can you help me work out timings

[Yakari]

So this morning, nothing, this afternoon DD has about 30 spots. I'm convinced they are chicken pox. We're living abroad so it's past 6 here, so nothing more can be done today but obviously she's been at school all day so I've let them know.
So my questions

1. obviously she is off school, what about her brother? Actually he has been immunized (her immunization was one of those things I never got to on my to do list )
   So far no spots, and if any appear or a fever then I'll keep him off - but in the absence of any symptoms? Does he go in?
   
2. you guessed it we have a holiday planned leaving on the 6th. That's 9 days from when spots appeared - is that ok? Or is it after they scab that you start counting. I know it's been done to death but Dr Google has differing opinions (this is assuming DS never gets any spots in the next few days - then of course we're screwed!)
   
   Just to be clear (and to avoid the bun fight) we will do everything we can to avoid infecting others but I'm just trying to work out the details.
   
   Thanks

So if I read correctly, your son is immunised and therefore very unlikely to get it. He doesn't need to stay off school.

I think your holiday should be fine - the spots need to have scabbed over but I think this generally happens within a week (it was 5 days for my DS).

Thanks for responding! That's what I thought but always good to get a second opinion.

Your daughter is fine for the holiday, your son may not be but luckily is immunised so no reason to believe he is incubating!
