Re India and Polio - here's what all the fuss is about, the original paper: India and Polio paper: Polio programme: let us declare victory and move on
It's an interesting story. Looks like the vaccine may have been over-administrated in some regions?
Paper:
“In the states of Uttar Pradesh (UP) and Bihar, which have pulse polio rounds nearly every month, the non-polio AFP rate is 25- and 35-fold higher than the international norms. The relationship of the non-polio AFP rate is curvilinear with a more steep increase beyond six doses of OPV in one year.”
WHO Guidelines:
“The primary series of 3 OPV vaccinations should be administered according to the schedules of national immunization programmes, for example at 6 weeks, 10 weeks, and 14 weeks, or at 2 months, 4 months, and 6 months. In addition, a birth dose should be given as soon as possible after birth when the potential for poliovirus importation is very high or high and the transmission potential is high or moderate”
I'd like to see any more studies on this if anyone can find them (I can't).
Even the biggest fan of the establishment view on vaccines would agree that bad things are very possibly going to happen if you over-administrate vaccines. It's all very well chucking money at a problem but this can blow back at you if the money is paying to administer medicine with side-effects.
Re what that has to do with ethics around herd protection - one may think (as that paper's authors do) that polio eradication is infeasible or at least not a sensible goal to pursue because there are better ways to spend the money. That's not the same thing as saying that trying to get herd protection effects is in any way a bad thing in itself.
I'd agree there are non-trivial ethical etc questions raised by herd protection concerns. The herd doesn't, or shouldn't, get to decide what everyone else does.
