20 out of the 23 were negative (87%) and two were weakly
positive. The third was definitely positive and was given a second
injection of alum toxoid. A further Schick Test made late in
January, 1936, proved all three to be negative.
No cases of Diphtheria or positive nose and throat swabs
occurred during this period.
St, Jude's Homes For Girls, Dagnall Park.
Out of 22 girls treated with alum toxoid 22 were Schick
Retested and 20 were negative (91%).
The two with slightly positive reactions are to be further
Schick Retested early next year, when it is hoped that the process
of immunization will have fully developed and negative results
will be obtained.
No cases of Diphtheria or positive nose and throat swabs
occurred during this period.
P.A.C. Homes at Queen's Road and 386, London Road.
12 and 25 cases respectively were treated with alum toxoid.
Two cases developed local and focal reactions lasting 48 hours,
but no general reactions resulted.
Sufficient time had not elapsed at the end of the year to proceed
with Schick Retesting. No cases of Diphtheria occurred during
this period.
Boys' Home, 106, Beulah Hill.
Following an outbreak of Diphtheria systematic immunization
was commenced. 17 boys were injected with alum toxoid and 14
were Schick Retested.
After 8 weeks, 11 were negative (78.6%), one doubtful, one
weakly positive, and one definitely positive.
After a further period of six weeks a second Schick Retest
showed one negative, one doubtful, and one positive.
The case, which was persistently positive, had had an acute
attack of faucial Diphtheria 6 months previously, for which he had
been given large doses of diphtheria antitoxin, and obviously he is
one of those cases in whom it is extremely difficult to stimulate the
formation of antibodies to a Diphtheria infection.
He has been given a further injection of alum toxoid, and a
further Schick Retest will be carried out after 2 months has elapsed.
