Local Reactions to T.A.F.—One slight reaction recorded.
Local Reaction to A.P.T.—21 slight reactions were recorded,
and 6, more severe ones, all after the 1st injection. One of the
latter was unusually severe but eventually settled down satisfactorily.
Diphtheria.
Previous.—38 cases gave a previous history of diphtheria
infection. 34 were found to be Schick negative and 4 were Schick
positive ; they were immunized with A.P.T.
Inter-current.—No case of diphtheria during the process of
immunization came to notice during 1938.
Subsequent.—One case of diphtheria in an immunized
person was reported in 1938; 3 were notified in 1937. The 1938
case was a moderately severe case, who made a complete recovery.
The question of diphtheria in the innoculated was discussed in last
year's report. In the particular case of diphtheria immunization
the occasional case of diphtheria in the "immunized" is bound
to occur, and should occasion no disquiet. The facts that they are
the exception, that a severe case in an immunized subject is unusual,
and fatal cases a rarity are sufficient to warrant the continuation
of the schemes. Immunization is definitely a preventive and lifesaving
procedure.
In the following tables further information is given in summary
form.
