DIPHTHERIA IMMUNISATION CLINIC.
Number of children immunised for the first time during
the year 1950:—

Grand Total of Children in the Borough who have received

(a) Under 5 years 2326
(b) Between 5 and 15 years 3857
Number of Children given re-inforcing doses during

At the 31st December the percentages of children who had
been immunised were as follows:—
(a) Under 5 years 69%
(b) Between 5 and 15 years 91.4%
From these figures it will be seen that the Diphtheria Immunisation
Scheme has been actively conducted during the year. The
number of children immunised for the first time was 801 compared
with 810 in 1949.
In addition the policy of giving single-reinforcing doses at appropriate
intervals during a child's school life has been continued.
The materials used are, for children under 10, Alum Precepitated
Toxoid and for children over 10 Toxoid Anti-Toxin Floccules.
T.A.F. is used for all reinforcing doses and is given subcutaneously.
