MMR - how soon after having it would you expect to get a reaction if any?

[Smurfs]

DD - 2.8 years is due to have her MMR on Monday and we are flying long haul on Tuesday, I know hideous timing but recent bouts of illness etc mean I have cancelled it numerous times and I would be keen that she has it before we travel.

How long after it would we expect a reaction if any?

Thank-you in advance.

I think it one week and then again at 3 weeks, dd1 had hers last week and is fine.

Gosh I'd ask your GP about that tbh before going ahead. OK chances are that you won't get a reaction but I do unfortunately know a few children who have become extremely unwell following MMR (HDU/ICU level of unwellness and/or seizures) and if that happened on a flight it would be pretty difficult.

WAre you travelling somewhere remote? Immunity won't be immediate anyway son unless you're going away for a while it might not confer immunity then.

Is this the first jab or the second? It's quite early for the second (I know they're making the second earlier but it's still early).

Thanks Marne, I don't fancy travelling with a poorly DD - it would be miserable for everybody

with DS it was 9-10 days before he showed any reaction and just as we thought he would be ok he reacted really quite badly and was very under the weather. So in theory it would be after your journey....

yurt1 - It would be DD first jab and we are off to S.Africa - off the beaten track at times yes.

thanks chocolateshoes - we will be there for just under a month so a reaction if there was one would hopefully be when there.

Are measles rates high in S Africa? I think immunity takes about a monthish to develop (the 3 week reaction you can get which is quite common is a kind of mini measles- usually just a rash- and a good thing as it at least shows it's worked), so I think the immunity develops after that. Someone like martianbishop will know. Unless you're going for a few months you won't be covered anyway.

Have a chat to your GP but I would be a bit cautious just because it's so soon afterwards. When I worry about measles for ds2 and ds3 I shove cold liver oil (vitamin A) down their necks!

Of course severe reactions are rare and the reason I know a number is because a lot of my friends have severely disabled children (so its a kind of self selecting group iyswim) but I'd really talk to your doctor (or some other open minded health professional that you trust) before going ahead.

yurt1 - rates vary hugely - where we will mainly be rates are low but might prevent us from really going out in the sticks! Thank you for your help will speak to family friend who is a consultant and see what they say.

That sounds a good idea. Ask how long it will take for immunity to develop as well as that might make a difference to your decision.

Kind of yurt to think of me, but sadly I've no real idea.

The antibody titre will rise with time, I'm not sure when the therapeutic level would be reached, and to a degree it will vary from child to child, since for some children it never get there IYSWIM

Thank you for having a think anyway will see what friend says and speak to Dr's on Monday morning...sorry to drag you away from the other thread

Thanks again yurt1

I was thinking about this while I was swimming with the kids (sad I know)

I would imagine that effective levels would occur at around the time a patient would normally recover from the illness (so the incubation time+ the time they are sick)

But that is assuming at the antibody titre cure for the vaccine is the same as it is for the 'real' virus.

Hmm, I may have a google and see what I can find.

yes that's what I thought mb- so I figured month (14-21 days incubation + week of illness)
