" For a society to function, we have to pull together collectively to help one another and ourselves ... and infects someone else's newborn who then goes deaf, (you) are acting selfishly and irresponsibly."
I have news for you, larry: People look out first and foremost for those they love. We will do things that benefit others, out of the goodness of our hearts, if and only if these altruistic acts have no real or perceived risk to ourselves & our loved ones. I will not donate a kidney for a stranger, nor will I walk a tightrope even if it means saving ten people from certain death (So yes, I am selfish, and so are you). I will, however, donate regularly and do voluntary work because that presents no risk to me and my family.
Similarly, I will not vaccinate DC with MMR because there seems to be a minute risk that they might then regress and become autistic. I know very well that the link is not proven and that the doctor who first suggested a link has been publicly crucified so that nobody else will research the subject. Still, I am not prepared to call the many parents who claim this link loons and paranoid delusional dimwits.
My primary responsibility is towards my children, not some faceless pregnant woman who should be responsible of her own health, rather than rely on my tiny baby. Faced with the minute risk of a grave and irreversible condition, I will refrain from vaccinating my children against mild childhood illnesses. DC have had measles vaccine. If they have not had mumps by the time they are pre-pubescent, they can have the vaccines then. DS has already had rubella, aged 4 months, and DD can have the rubella vaccine before she starts university, if she is not already immune by then.
All this and more have been studied with Game Theory. I have previously linked to a few such analyses on other vaccine threads, all of which conclude that it is perfectly rational for parents not to vaccinate their children under these circumstances. You should be able to find them if you search my posts.
