IMMUNISATION AGAINST DIPHTHERIA
During 1941 the routine of the Diphtheria Immunisation Clinics
remained unchanged, that is to say, ilium precipitated toxoid was the
prophylactic used, and Schick testing both before and after treatment
was, except for a few cases, dispensed with. This meant only two
visits compared with four or five of former years.
New cases came from the following sources-
School cases 4477
Infant Welfare eases 12-39
Others under 5 years 923
