*These two cases occurred before the elapse of 9 months, the period laid down at Edinburgh as required to secure artificial immunisation.

The above table shows that only three of the children were re-tested after the last injection. It cannot be assumed that immunity
invariably follows the administration of three immunising injections, nor that immunity even when once established is invariably
permanent. Drs. Parish and Okell have shown that of 440 Schick positive children who were rendered Schick negative by
immunisation, 5 per cent.were found to be positive when retested 1-7 years later.
