primary vaccination and, as a rule, welcome the vaccinator, but   in the case
of re-vaccination it is different; few understand the necessity for   it with the
result that it is only practiced at all freely in the presence of an   epidemic of
smallpox.

House to house vac-
cination.

7. There was a total of 17,735 operations performed under the house to
house system in 9 districts, viz., 60 in Simla, 178 in Jhelum, 240 in Amritsar,
629 in Montgomery, 1,037 in Ferozepore, 1,087 in Shahpur, 1,162 in Karnal,
2,988 in Hissar and 10,354 in Lahore including 7,854 in the Lahore Munici-

District stuff.
Statement No. I.

8. The total number of operations performed by the district staff was
738,797 as against 841,186 in the previous year showing a decrease of 102,389.
There was a decrease of 83,634 and of 18,755 in primary and re-vaccinations
respectively. In the case of primary operations 7 districts recorded an excess
and 21 a decrease. The diminution is partly due to the fact that in some of
the districts vaccinators were sent for training to the Punjab Vaccine Institute
and they were replaced by vaccinators from the Special Staff, Punjab, whose
work is shown separately, and partly to the reasons given in paragraph 6.
This year the Special Staff, Punjab, vaccinated a whole tahsil in the Lahore
District instead of only a few villages as in forager years.

The percentage of males and females to total number of re-vaccinations
was 65.95 in the case of males and 34.05 in that of females as against 6698
and 33.02 in the preceding year. The percentage of success in primary vac-
cination was 98.25 as against 95.22 in the previous year, while in the case of
re-vaccination it was 77.16 as compared with 71.89. This satisfactory result
may well be due to the training of the vaccination staff in the Punjab Vaccine
Institute. The percentage of vaccinations in which results were not known to
the total number in 1917-18 was 4.80 in the case of primary and 18.71 in that
of re-vaccination as compared with 5.31 and l9.64, respectively, in the year
preceding.
