Howto that's a good point. I wonder if the nonimmunisers would be as confident in their decision if herd immunity didn't exist: I.e. If there was a very real danger that, if kids weren't immunized, they might get ill.
Electra: I totally agree that vaccinations aren't for everyone. There are a very small minority of children for whom vaccinations are potentially more of a risk than the illness they're given to prevent. These kids are usually (ok maybe not always) identified by
consultants etc. Eg, my DD nearly didn't get her MMR booster: she had a very nasty, prolonged febrile convulsion when she had chickenpox earlier this year, and was being investigated for epilepsy as a result. The jab was delayed while they did EEGs etc on
the advice of her consultant and the paediatric neurologist. She was given the jab when they gave her the all clear. Riven's DD is classic example of a child for whom immunizations are more of a risk than the possibility of catching the illness they aim to present. I can also see why people with family history of complications steer clear of them.
My concern is for those with perfectly healthy DC who decide not to have them immunized. Those kids who shouldn't be immunized, eg Riven's DD, really need the benefit of herd immunity. That's why I think that everyone who can be immunized should be immunized, to maintain herd immunity and protect the kids who can't have the jabs.
I recognize that it's a really difficult issue though, and that people agonize over it. I do myself, and do as much research as I can. I have always found that the evidence favors immunization. That said, I hate getting them done and I will be shitting myself when DD2 gets her MMR next year, given that it gave her big sister a febrile convulsion
