Poliovirus vaccine strains revert to virulence which multiplying in
the human gut. Reversion is not a consequence of recombination with
wild type strains as you suggest. This is clear for the type 2 strain
as the wild type virus had been eradicated. There is no reservoir host
for poliovirus other than humans.

Administration of live polio vaccine, is likely the organism can revert back to the wild form. all it is because of viral genetic recombination mutant to access the virulent genes from wild strain from the environment or resovoir host. be careful WHO it will be pandemic.

Instead of heads rolling, I think more good would be done by using global resources to take care of the victims of vaccines gone bad. The lives of those children and their families are altered forever either way, but I don't think they would all hate and mistrust the people that brought that vaccine into their country if those people acted responsibly now. If the victims are abandoned, they will feel badly used by the herd, and rightly so.

So, in other words: The vaccine doesn't work, therefore, we must use more vaccine?

I understand and agree.

But as an informed layperson I could tell at the time that there was at least a shred of competent anecdotal evidence to the contrary.

And for such a prominent body to heap scorn on those who disagreed in good faith only contributed to the polarization in Northern Nigeria. This phenomenon is NOT unrelated to the strengthening of radical Islam in that area and now al Qaeda is establishing a foothold and more there.

The end result of this very important event in recent northern Nigerian history is that the credibility of the radical Islamists in that region was dramatically increased among the local population. That's a horrific outcome and heads should roll because of it. The people of Northern Nigeria are hot as Hades about the entire episode, as they well should be.

I remember hearing a local leader speaking on the subject at the time. I was expecting to hear some blathering idiot, which is how the BBC treated his commentary. But after listening carefully to his views, I could not exclude the possibility that he could be at least partially correct. I was stunned. It seemed that there was just too much smoke there to exclude further inquiry. Something was clearly going on.

At the time, I recall polio was on the ropes. This was the last area in the world, to my knowledge, where polio existed. Then I watched over the years with horror and dread as it reappeared in several nations.

For many years the WHO line was that vaccine-derived polioviruses
could not cause polio, nor could they be transmitted among humans. The
outbreak of vaccine-derived disease in 2000 in Haiti and subsequently
in several other countries changed that incorrect view.

I distinctly and clearly recall the BBC featuring an extensive interview with a representative of the WHO at the time of the Nigerian boycott sneering and scoffing and mocking the absolutely “preposterous” notion that there could be ANY relationship between this vaccination and infection with polio. In fact the BBC speculated that since this revolt against the vaccination program was part of an al Qaeda strategy of disinformation.

This line of scorn and derision was repeated throughout the AP and Reuters at the time as well.

Thank you, Dr. Racaniello, for having this dream. I hope very much that momentum builds to deliver safe, killed polio vaccine to the regions of the world that still need it. It seems imperative to me.

Wow. This reminds me of the theme of Edward Tenner's book, “Why Things Bite Back: Technology and the Revenge of Unintended Consequences”. The more we try to fix things, the more we can sometimes end up making them more complicated for ourselves, it seems.
