"Except that there's no pre-jab screening to determine if there is a medical reason"
What screening programme could there be? How many pre-existing conditions that you wouldn't know you had, but might have serious interaction with a vaccine are there?
No titre test to see if the person is already immune.
Not cost effective. Won't substantially reduce harm. 99.99% of people will not already be immune to M,M or R for example- that's the point.
no dose control based on body weight,
Why would that ever be necessary for a vaccine? The dose is tiny and quantity make little difference- that's how vaccines work.
no mandatory reporting of adverse events
Are you sure? I thought there was for new vaccines under longitudinal study, just like any other newly authorised medicine? Obviously not for the measles jab because we have the data.
"or even clear guidance on what an adverse event is."
Again- what do you base that on? I had an adverse reaction after a flu jab once. Went in happy to be told it was coincidence but the doc was pretty clear it was a known potential immune response to that vaccine. That's one reason why flu jabs aren't given to everyone- the risks of the disease aren't as high as measles or tetanus, so the risk balance is different.
"Not taking a stand either way here, just musing."
If you don't accept the premise that vaccines in general save huge numbers of lives, and not having the basic jabs is awful parenting, then you are just another nut trying to undermine vaccines.
If you do then I think it's reasonable to discuss some of the potential grey areas with some vaccines in marginal cases- the danger is that the loons use nuance as an opening to give validity to silly claims.
