IMMUNISATION AT RESIDENTIAL SCHOOLS AND
HOMES.
Prior to October only one injection of Alum Precipitated Toxoid
was given to all Schick positive reactions. Since, however, the
results—as in the latter part of 1935—showed a higher percentage
of non-immunes after this treatment than after treatment with
Toxoid Anti-toxin Mixture, or Toxoid Anti-toxin Floccules, either
in the various institutions or at the Clinic, it was decided in October
to give 2 doses of A.P.T. 0.1 cc followed a week later by 0.5 cc.
As, however, this method of treatment was only commenced
after 20th October, 1936, it has been impossible so far to retest and
make any reliable comparison with the results already obtained
after only one injection, as shown in Table below.
No reactions were reported, but where only one injection was
given, the children were not seen again for 3 or more months if at
all, and thus reactions were not investigated.
Other Treatment prior to 20th October, 1936, included the
following:—
Fidelis Convent, Central Hill, Upper Norwood.—4 who had
completed course of T.A.M. (3 x 1.0 cc) were retested and found
to he Schick negative.
1 primary Schick Test was repeated because of uncertainty and
result was negative.
Children's Infirmary, Central Hill Convent, Upper Norwood.—
3 who had completed course of T.A.M. (3 x 1.0 cc) were retested
and found to be Schick negative.
P.A.C. (Queen's Road) Homes.—4 children were reschicked
after completion of course of T.A.M. (3 x 1.0 cc) and all were
negative.
P.A.C. (London Road) Homes.—3 children transferred from
Brighton P.A.C. Homes completed course of T.A.F. and have not\
yet been reschicked. 3 received a 2nd reschick test after the injecI'on
of A.P.T., and one proved to be negative and two positive.
St. Jude s Homes for Girls, Dagnall Park.—3 primary Schick
Test were repeated because of doubt of result of original test—
these were all negative.
