IMMUNISATION AND VACCINATION IN THE
CONTROL OF INFECTIOUS DISEASE
The following tables gives a rough estimate of the extent to
which the population of Wood Green is protected by immunisation
from the various infectious diseases. This is based on our knowledge
of the rate of immunisation obtaining in children from infancy to
15 years of age covering the period from 1935 to the present date.
(The figures do not, however, take account of movements of
population into or out of the Borough except as regards children
under the age of 2).
Disease
Age range of population of Wood Green
estimated to possess useful protection
conferred by vaccination or immunisation
Diphtheria
From infancy to approximate age 40.
During 1964 90.9% of children reaching
the age of 2 years had been immunised
Whooping cough
From infancy to age 40
Tetanus
From infancy to age 20, plus 87 of staff of
Wood Green Borough Council
Smallpox
From infancy to approximately 10 years
very fully protected and to perhaps 15
or 20 years fairly fully protected. Varying
number in ages beyond this. During
1964 79% of children reaching the age
of 2 years had been successfully vaccinated
Poliomyelitis
From infancy to age 25 very full protected
and also to a lesser extent up to age 50
or over
Tuberculosis
Ages 13 to 24 very fully protected. This
is the group who have received B.C.G.
vaccination in school. The consent rate
to B.C.G. vaccination for 1964 was 79%
Measles
Several children aged 1 to 2 years were
vaccinated during 1964 under the
research scheme of the Medical Research
Council. 1965 is expected to be an
epidemic year for measles and this will
test the efficacy of the vaccine in those
children whose parents volunteered to
take part in the trial
