Number of Children given boosting doses during 1947:—
(a) Under 5 years 135
(b) Between 5 and 15 years 1,023
At the 31st December the percentages of children who
had been immunised were as follows:—
0—5 years 59%
5—15 years 88%
If it is remembered that during the year eight hundred
infants were added to the population and that, therefore, there
must always be a number who are not yet old enough for
immunisation, it will be seen that the figures are very satisfactory.
The policy of giving single small reinforcing doses at
appropriate intervals during a child's life has been pursued.
Over three times as many such doses were given in 1947 as in
1946.
The materials used are, for children under 10 years, Alum
Precipitated Toxoid, and, for children over 10, Toxoid AntiFoxin
Floccules. The number of reactions resulting from the
use of these materials has been very small.
Immunization Against Whooping Cough
For some time now immunization against Whooping
Cough has been available to Richmond residents. As the
efficacy of the vaccine still remains in doubt, no effort has
been made to encourage parents to have their children protected
.
In spite of this there has been a growing demand and
during the year 93 children received full courses of the injections.
The material used is Alum Precipitated Vaccine
(Glaxo Laboratories Ltd.), and the course consists of two
injections of 0.5 c.c. followed by a final injection of 1.0 c.c.
