Ratio of persona Successfully vaccinated per 1,000 of
population.—Statement No. I.
10. The number of persons successfully vaccinated by the district staff
during the year was at the rate of 32.59
per mille of population, as against 27.93
in 1909-10 and 27.83 in 1908-09. The
corresponding rate during the triennial period ending 1910-11 was 29.45 as
against 29.99 for the preceding period. The rate of 32.59 is the highest on
record since 1899-1900 when it was 36.30.
Special Staff.
Statement No. I and its Appendix.
11. The special staff during the triennial period performed 90,300
operations of which 47,678 were primary
and 42,622 re-vaccination, compared with
177,750, namely, 149,096 primary and
28,654 revaccinations during the previous period. In 1910-11 there were
12,160 primary vaccinations and 7,328 re-vaccinations as against 16,870
and 11,908 in 1909-10 and 18,648 and 23,386 in 1908-09 respectively.
The diminution in 1908-09 was attributed to the infantile mortality
in the autumn of 1908 and also to the number of vaccinators being reduced
from 16 to 14 and to the employment of 6 vaccinators at the Punjab Vaccine
Institute for the preparation of vaccine, while in 1909-10 and 1910-11 it was
reported to be chiefly due to the confinement of the staff entirely to the hills
which are consequently visited annually instead of at greater intervals of time.
The result is that there are fewer persons available for vaccination each year as
compared with former years. Another reason for the decrease is that some
vaccinators were employed on cholera duty in the Simla hills for about three
months in 1910.
The special staff other than those employed in the Vaccine Institute are-
divided into two parties each under a Superintendent of Vaccination ; they are
posted in rotation to the Native Hill States and in order to exercise more control
over their work, Superintendents and Vaccinators are required to submit weekly
diaries in which they report their daily movements, the number of vaccinations
performed or inspected and any other matters of interest coming to their
notice.
Percentage of succesful.
12. The percentage of success in operations performed by the special
staff was 94.39 in primary and 67.97 in
re-vaccination as against 95.92 and 65.09
in the year preceding.
Cantonment Staff, Annual Form No. I and its Ap-
pendix.
13. The total number of operations performed in the cantonments which
entertain their own vaccinators, in the
triennial period 1908-11, amounted to
15,983 as compared with 25,481 in the
previous triennial period, a decrease of 9,498. Of this diminution 2,958 cases
were primary aud 6,540 revaccination.
The largest decrease in primary operations was 922 in Ferozepore Can-
tonment, 745 in Sialkot, 629 in Lahore and 563 in Ambala. The decrease in
re-vaccination was highest in the cantonments of Ambala (2,184), Lahore (2,056)
and Rawalpindi (1,520).
In 1910-11 there were 3,377 primary and 1,877 re-vaccinations as com-
pared with 3,433 and 2,183, respectively, in 1909-10. The largest primary vacci-
nations (1,051) and re-vaccinations (737) were performed in the Ambala can-
tonment.
The percentage of success was 99.01 in primary and 54.97 in re-vacci-
nation as against 98.58 and 71.77 in the previous year, and the ratio per cent,
of unknown cases to total cases in the case of primary was 1.57, and in re-vacci-
nation 15.77 as compared with 1.81 and 11.41 in 1909-10.
