As before, I have encouraged the mothers to bring their children to the clinic.
two years after a negative Schick test to ascertain that the immunity had not
been lost. One hundred and six children were tested in that way and six proved
to be positive again and had to be re-immunised. This high percentage proves
that the practice of re-testing children every two years until the age of about
ten is highly justifiable and must be encouraged everywhere. Thirteen immunised
childr n were reported to have contracted diphtheria during the year, but only
four actually had clinical diphtheria, which was mild in each case. Two out
of these four cases could have been prevented, if the children had been re-tested
as I have advocated above.
Again I wish to thank the nursing and clerical staff at the clinics for their
excellent help under adverse conditions.
