can my child catch measles from recently vaccinated MMR?

[ruty]

Sorry not trying to be controversial no backlash please! We're going to wait to give 12 month old ds singles when he is a bit older due to gut problems. thing is, some of his friends are now due for MMR. Can he catch measles from one of them? Is there a time span after the jab when it is safer? Maybe Bakabat out there might know...

As far as I know, no he can't because the vaccine doesn't contain live measles. The reaction that some children get which gives a measles-like rash is not infectious.

[bakabat]

It does contain live measles (sorry WWB- it does!), but I haven't heard of anyone catching it via a jab (except on here). The time to avoid would be the snotty nose time until the rash went. I do think its unlikely though ruty- and despite the gut problems I wouldn't worry too much. If he got it - it would be the jabbed form so you could avoid the jab altogether

[bakabat]

oh - I haven;t heard of anyone cagtching it on here- but someone's dr made a muttered comment to that sort of effect iyswim.

[ruty]

thanks bakabat - do you know how long the rash lasts and how long to avoid to be absolutely safe? 48 hours ok or should i leave it a week? Got a friend coming and i think i'll have to ask her when her ds is having mmr just to be safe. [paranoid? moi?]

[bakabat]

Wait until its gone completely ruty to be safe. (usually appears on the 3rd week after MMR so leave it 4 weeks post MMR and you should be fine).

Every time I see your name I feel all warm inside (seriously I am so pleased you went gfcf and all the horrible stuff that was happening has stopped and you've got the magic point - I am manically singing wind the bobbin up to ds3 (9 months).)

[ruty]

aw thanks bakabat - i have to say that I am very grateful to you for all the help and guidance - who knows, it may have played a rather significant role in getting to this point. I am so over the moon about the pointing. couldn't have dreamt about it happening at 9 months tho so hang on in there!

My nurse told me that the only part of the MMR which was infectious to others was the mumps - which is why you had to be very careful when changing dirty nappies if you weren't immunised.
And they have managed to change that part of the vaccine recently so that no longer applies.
I would have thought therefore that there was no risk of infection at all from the measles part.

[bakabat]

he's started copying ruty- and does little turn taking clapping games so I'm fairly relaxed at the moment. Was so pleased when I read your pointing comment a few weeks ago I rushed off to tell dh.

bakabat in our area they STOPPED it being a live vaccine just over a year ago...

HV gave me the impression it was a nationwide thing. Round here, at least, it definitely is NOT a live vaccine

[bakabat]

This is from an NHS website: "There are two brands of MMR vaccine currently in use in the UK.
The first, MMR-ll, manufactured by Aventis Pasteur MSD uses the Enders line of the Edmonston strain of measles virus; the Jeryl Lynn mumps virus, and Wistar, RA 27/3 strain of rubella virus.
The second, Priorix is manufactured by GlaxoSmithKline and uses the Schwartz strain of measles virus, RIT 4385 mumps (obtained from Jeryl Lynn) and Wistar, RA 27/3 rubella."

Both MMR-II and Priorix contain live vaccine,

Are you sure you are not confusing it with then polio jab? That changed from OPV (live) to injected just over a year ago- which is supposedly why the early jabs were changed to the 5 in 1's (absolutely nothing to do with that paper published a few months before showing that giving thimerosal to mice prone to autoimmunity triggered autism- no, no the switch was nothing to do with that at all, all to do with polio.

I would be very interested if they had switched to a non-live form of melases and would wonder why (measles virus in gut and spinal fluid perhaps?) So if anyone knows a brand name please let me know.

[bakabat]

I've searched and searched and can only find reference live (attenuated) viruses in the MMR. I think you (or your HV) must be confusing it with polio.

However they do say that it doesn't transmit. So to go back to the original don't worry too much ruty (although tbh would be hard to test as most older adults are immune and the younger generation are vaccinated). If you're going to worry about it though then I would say avoid for 4 weeks.

[ruty]

i think the former OPV [oral polio vaccine] was the only vaccine you could potentially catch from changing nappies cupcakes.
Bakabat not sure my ds was doing clapping games at 9 months so thats definitely good news. I wonder if they could make a vaccine for measles that wasn't a live virus? They dragged their heels on changing the polio to a dead vaccine, so i suppose it will take an age for them to change it, and if they did they would then kind of being admitting that there could be potential problems with the current MMR.

I will have to pluck up the courage to ask my friend who is coming to visit tomorrow when her ds had the MMR...
