34. Thank goodness. I can understand a little when people have a fear that it might induce an autistic condition in a child who appeared to be absent that, prior to vaccination (however shaky the apparent evidence to that effect is), which is the primary objection to the combined measles, mumps and rubella jab, but given the choice between that and likely death or permanent injury in the case of the diseases mentioned, there isn't a shadow of a doubt in my mind which I would choose.
