prevalent in many towns and districts of the province during the year. The
towns principally affected were Delhi and Lahore and the districts Jhelum,
Mianwali, Delhi and Rawalpindi. At the commencement of the vaccination
season the attention of all Civil Surgeons was invited to the prevalence of
small-pox and the consequent necessity for special attention to vaccination.
House-to-house vaccination.
7. The experiment of house-to-house vaccination was again carried out
this year and 105,400 operations were
performed in this manner. The system
is appreciated in the districts of Hissar and Jullundur and is liked by the
people of the Gurdaspur district where 20,318 operations were performed. In
the remaining districts it did not prove a success, partly because of the inter-
ference with the privacy of the people, and partly to the delay and wastage of
time of Vaccinators. Experience shows that a much larger staff would be
required to perform vaccinations by this system. Moreover in doing house-to-
house vaccination vaccine lymph has to be exposed to the sun frequently, thus
giving unsatisfactory results. The Civil Surgeon of Rawalpindi reports that
a Vaccinator was beaten when performing house-to-house vaccination.
In view of these circumstances, I do not recommend any further trial
of this experiment, though in places where a distinct demand is made for house-
to house vaccination it might be carried out should it be found to require no
increase in the vaccination establishment.
District staff.—Statement No. I.
8. Compared with the work for the previous year there was an
increase of 102,642 operations perform-
ed by the district staff in 1911-12. Of
this number 53,303 were primary vaccinations and 49,339 re-vaccinations.
Every district in the province shared in the increase in primary vaccinations
excepting Hoshiarpur, Jullundur and Sialkot, in which the decrease amounted
in 1,021,429 and 2,357 operations, respectively.
In the district of Lahore the increase was more than 11,000 next to
which comes Muzaffargarh with an increase of over 4,000 operations ; increases
of more than 3,000 operations were noticed in the districts of Ferozepore
(3,921), Hissar (3,384), Delhi (3,200), Multan (3,054) and Rohtak (3,027).
In regard to re-vaccinations an increase was noticed in 22 and a
decrcase in 7 districts, namely, Karnal, Kangra, Hoshiarpur, Gurdaspur, Rawal-
pindi, Jhang and Multan. This decrease is principally due to differences in
the population of areas selected for re-vaccination.
The ratio of successful primary vaccination of children under one year
of age to their total number available for such purpose was 74.08 against
70.49 per cent. in the previous year. The increase of 3.59 per cent. may be
taken as an indication of the district vaccination staff having worked well
during the year under review. It is also possibly partly due to the increased
demand for vaccination owing to the prevalence of small-pox in certain dis-
tricts already mentioned.
District staff. Percentage
of success —Annual
Statement No. I.
9. The percentage of success in primary vaccinations performed by
the district staff in 1911-12 was 95.15
as against 97.24 in 1910-11, while in
the case of re-vaccinations it was 72.69
in 1911-12 as against 73.90 in 1910-11. The percentage of vaccinations in
which results were not known to total number in 1911-12 was 4 27 in the
case of primary vaccinations and 16.04 in that of re-vaccinations as compared
with 3.52 and 16.16, respectively, in the previous year. The fall in the
percentage of success is explained in paragraph 18 of this report.
Ratio of persons successfully vaccinated per 1,000 of
population—Statement No. I.
10. The number of persons successfully vaccinated by the district
staff was 36.22 per mille of population
in 1911-12 as against 32.59 in the year
preceding.
Special staff—Statement No. I and its Appendix.
11. During the year under report the special staff of Vaccinators per-
formed 37,773 operations of which
21,705 were primary and 16,068 re-
vaccinations, showing an increase of
9,545 and 8,740, respectively, as compared with last year. The Deputy Sanitary
Commissioner reports that this satisfactory feature of the amount of work done
by the staff is chiefly due to the close scrutiny exercised over their work by
means of checking their weekly diaries. The system under which the special
vaccination staff other than those employed in the Punjab Vaccine Institute
worked during the year was chiefly in two groups. They were posted in
