Vaccination.—I have not in my capacity of Medical Officer of
Health had occasion to perform any vaccinations under the Public
Health (Small.pox Prevention) Regulations, 1917.
The following particulars with reference to the state as regards,
vaccination on the 31st December, 1926, in respect of the 435
infants whose births were registered between 1st January and the
31st December, 1926, have been supplied to me by the Vaccination
Officer for the District: —
Births registered 435
Certificates of successful Vaccination 341
Certificates of exemption (statutory declarations) 90
Diphtheria. —Remarkably few cases of this disease occurred
in the District during 1926; only twelve cases were notified, being
the smallest number notified in any year since 1894, when there
were eleven cases. No case occurred during the last three months
of the year.
The relative freedom of the District from diphtheria is all
the more remarkable as the incidence of the disease in the County
of London was high. The incidence (cases per 1,000 of the population)
for Barnes was 0.33, that for London being 2.97, and for
England and Wales 1.36.
No death from diphtheria occurred in this District. The
Mortality Rate (deaths per 100 cases) for London was 3.95.
The incidence.rate (cases per 1,000 of the population), the
percentage of notified cases removed to Hospital, and the mortality.
rate per 100 cases during the year 1926 and during the previous
10 years are given in the subjoined Table.
