Was this a reasonable price to pay to eliminate polio?
Was it a necessary price to pay? That is, could we have eliminated polio without also spreading SV40?
Is this the law of unintended consequences at work? Or was this carelessness?When is it a wiser choice to wait for better science, and when are the known problems so severe that it's better to charge forward with imperfect technology?

Please note!!! The vaccine detailed in this story has not been used in the United States for 50 years. The vaccine currently in use in the United States is the IPV. Unlike the OPV, it is completely dead. The IPV cannot spread live viruses of any kind.
