Dr Garrott Allen wrote "Post-transfusion hepatitis, a serious clinical problem" in California Medicine, estimating that the additional risk created by paid donations mixed in commercial pools in the US suggested that products made from those pools were ten times more likely to transmit hepatitis than if unremunerated voluntary donations had been used, simply by reason of the source of the plasma used.

A List of Documents of the Central Blood Laboratories Authority was published recording batch histories which show an increase in pool sizes from 1978 (when batch histories begin) to 1986. They rose from 2,250 donations in a batch to 6,000.

Dr Snape wrote a memo to Peter Prince and Dr Smith recording a figure of 25,000 donations in June 1986 (although this was after heat treatment had been introduced, and hence it was at a time when viral inactivation might reasonably have been thought to have been achieved, even though the definitive studies on hepatitis transmission had not yet shown conclusively that 8Y was free of transmitting such a virus).
