Position of Original Groups at time of Schick Test.
Group 1. Receiving three injections of T.A.F. 149 boys.
Of the 149 boys—
116 were Schick tested;
26 had been licensed;
3 had been sent to Borstal;
2 had absconded;
1 had been transferred;
1 was in Gravesend Hospital.
Group 2. Eeceiving two injections of T.A.F. 1 boy.
This boy was on leave at the time of third injection of T.A.F.; on return he was licensed, and
his injections were not completed nor was he Schick tested.
Group 4. Eeceiving one injection of T.A.F. 8 boys.
The immunisation of the five new boys was completed, but one was subsequently licensed, and
only four were tested. The two boys in hospital were Schick tested. The boy on leave was licensed
on return.
Group 6. Eeceiving no injections of T.A.F. 4 boys.
These boys were in hospital at time of immunisation. One died in hospital, another was
transferred to a land institution, the remaining two were tested.
Available for Schick Testing—
Group 1 116 boys
„ 2 0 „
„ 4 6 „
„ 6 2 „
124 boys
out of original 175 boys.
Method of Schick Testing.
Messrs. Borroughs Wellcome & Co.'s products were again used. 0.2 cc. of Schick Test Toxin was
injected intradermally into the right forearm, and 0.2 cc. of the Schick Control into the left forearm.
The results were read twenty-four hours later, and again after a second twenty-four hours where
necessary.
The results obtained may be divided into four groups:—
A. Negative.
B. Negative and Pseudo.
C. Positive and Pseudo Combined.
D. Positive.
Groups "A" and "B" indicate that the immunisation was successful, i.e., the boys are no longer
susceptible to diphtheria.
Groups "C" and "D" indicate that the immunisation has failed or been only partly successful,
and a second series of injections with T.A.F. should be carried out on these boys.
Eesults—
A. Negative 95
B. Negative and Pseudo 17
C. Positive and Pseudo Combined 9
D. Positive 3
There are thus still twelve boys out of the 124 tested, susceptible to diphtheria. This represents an
immunity of just over 90 per cent. This figure is rather lower than that usually obtained by this method
of immunisation, but may be regarded as satisfactory.
With one exception the boys exhibiting positive reactions had received the normal course of three
injections of T.A.F., i.e., belonged to Group 1.
It is to be expected that the twelve boys in Groups "C" and "D" are partially immune, but to
assure 100 per cent. immunity, a second series of T.A.F. injections has been commenced.
