Single lots of vaccinations are spread out over a wide geographical area which prevents the doctors and public from connecting the cause of illness to a specific batch of vaccine

Wythe Memo - August 27, 1979

"After the reporting of the SID cases in Tennessee, we discussed the merits of limiting distribution of a large number of vials from a single lot to a single state, county or city health department and obtained agreement from the senior management staff to proceed with such a plan."

Wyeth Memo

...except there is an analogy here that goes way beyond the memo. Barbara Loe Fisher and Harris Coulter lay it all out in "A Shot in the Dark," subtitled "Why the P in the DPT vaccination may be hazardous to your child's health." Barbara is regularly portrayed in the media as an anti-vaccine zealot, but the book's discussion of what happened in Tennessee is pretty convincing. (And she was instrumental in getting a safer version of the vaccine onto the market.) From the book:

"When statistics are applied to the study of vaccines, political immunology demonstrates its infinite flexibility: statistical evidence demonstrating cause and effect is denied, when this same evidence, applied to any other branch of medicine, would be accepted without question," Coulter and Fisher write.

"This convenient method of reasoning was displayed with particular clarity in connection with the government's investigation of SIDS deaths in Tennessee. In 1978-79, eleven babies were found to have died within eight days of a DPT vaccination. Nine of the eleven had been vaccinated with the same lot of pertussis vaccine, Wyeth #64201 and five (four from the same lot) had died within twenty-four hours of vaccination.
