DS has an egg allergy. He had his first MMR with no side effects before this was diagnosed.
He is now due for his 4 year booster. The doctors surgergy says it must be done in the hospital under supervision.
This makes me VERY nervous. Does anyone know how likely a reaction is and how dangerous this might be?
No shock thank heavens - just vomiting to anything with a trace of egg on/in it anything up to a couple of hours later - At least that's all i've seen so far. We avoid it madly as clearing up vomit is not my favourite activity. let alone the horribleness of having sick child.
The paed did tell DH at last visit that egg is such a large protein it is rarely absorbed into the body - the body just vomits it out first so that is why I don't know.
If this is true and there is the possibility of egg in the vaccine its going directly into the body so I've no idea how he would react.
Does that make sense or am I rambling?
The measles part of the MMR is cultured on the chick's embryo as are alot of vaccines. You can find this info on the internet.
I did the single vaccines for DS who has an egg allergy and no reaction. Was told there is a clinic that does the single vaccines NOT cultured on a chick embryo but didn't feel it necessary to go that route.
When I was weighing it up (didn't do it in the end, but that was more to do with the neomycin) I spoke to a paed. who said they had had 1 reaction at the hospital in 5 years, and that the kid was allergic to heaps of things and it could have been any component.
My GP did not want to do the MMR at all. For one thing he didn't have the facilities for us to wait a couple of hours after the injection except in the waiting room, which wasn't ideal. I think he was also freaked out at the possibility of having to resuss a toddler without being in a A&E department.
Bobybob - I think that is the reason for my GP refusing too.
Interesting about chick embryo rather than egg.DS eats chicken no problems. I wonder when the change comes that stops the allergic process I guess it is the protein in the egg itself that the chick uses in development that causes the problem and not the protein in the muscle which is what you eat in a chicken.
I'm sure that the hospital originally told us that there was no problem but the nurse at the GP surgery rang the manufacturers of the vaccine and was told that it was cultured on egg. I don't know who to beleive any more.
I think I will have it done, but it does worry me that all the medical professionals seem to have such differing opinions.
My son is allergy to eggs, wierdly it seems to be if egg is eaten pure (fried, scrambled, quiche) but not in a cake or pancakes, something to do with proteins. I am still very careful and we decided to have single jabs and this worked well for us because there was something in the separate one that are given at 4 months that reacted with him.
We were offered the mmr in the hospital but the clinic that we went to gave me all the reassurance that we needed about how much egg was in it and they took alot of care of him and said we could stay around as long as we need and had an epip pen and adrenalin ready if he did react.
