FOR THE YEAR 1906-1907.
Total number of persons
primarily and re-vaccinated,
Appendix I, Statement I,
column 6 and Statement III,
column 4.
During the year under report there were 591,677 persons primarily
vaccinated and 37,507 re-vaccinated against 610,130
and 45,340 in the previous year, showing a
decrease of 18,453 in primary and 7,833 in re-
vaccination.
Increase or decrease by
Registration Districts.
2. In Western Registration District there was a decrease of 2,836 in the
number of persons primarily vaccinated compared with
the previous year, and an increase of 1,541 in re-
vaccination. The decrease in primary vaccination
must be attributed to interruptions in work caused by the attendance of
vaccinators on classes of instruction in the use of preserved lymph.
3. In the Presidency Circle, Bombay, there was a decrease of 1,369 in the
number of persons primarily vaccinated and of 2,790 in re-vaccination. In
Bombay the supply of lymph was interfered with owing to an outbreak of
rinderpest among the calves, and vaccination was interrupted by the extra work
thrown on the staff in the preparation of glycerinated vaccine.
4. In the Central Registration District there was an increase of 3,938 in
the number of persons primarily vaccinated and a decrease of 2,571 in re-
vaccination.
5. In the Southern Registration District there was an increrse of 5,177
in the number of persons primarily vaccinated and of 1,266 in re-vaccination.
6. In the Gujarát Registration District there was a decrease of 1,471 in the
number of persons primarily vaccinated and in re-vaccination of 1,049. The
decrease in primary vaccinations occurred only in Native States, of which there
are an unusual number attached to the Gujarát District, and in which the same
supervision as obtains in British Territory cannot be maintained with the
existing staff.
7. In the Sind Registration District there was a decrease of 18,554 in the
number of persons primarily vaccinated and of 4,033 in re-vaccination. The
decrease in vaccination is most marked in this district, the chief cause being a
great prevalence of malarial fever among young and old of all classes. This
outbreak was the result of widespread inundations due to heavy rain and an
abnormally high and late rise of the Indus.
8. There was a decrease of 2,140 in the number of persons primarily
vaccinated and 197 in re-vaccination in the Settlement of Aden.
Infants successfully vacci-
nated as compared with the
number available.
9. Excluding Native States and Aden, the number of infants available
for vaccination, after deducting deaths under one year
of age from births, was 487,689 against 473,961 in
1905-06, of whom 368,819 or 75.63 per cent. were
successfully vaccinated, compared with 81.08 per cent.
in the previous year.

persons primarily vaccinated,
Appendix 1, Statements Nos. I
and III.
10. Out of 591,677 persons primarily vaccinated, 528,576 or 89.34 per cent
were successful, 22,452 or 3.79 unsuccessful, while in
42,323 cases the result could not be ascertained as the
children were not brought for inspection. In the case
of 1,674 persons a second operation was done on account
of failure on the first occasion. The percentage of
success excluding ''unknown cases" was 95.93. The number of persons successful-
ly vaccinated per 1,000 of population fell from 27.22 for the previous year to
25.32 during the year under report.

11. During the year 37,507 persons were re-vaccinated. The number of

8,946 instances the result could not be ascertained and
in 8,272 the operation failed. In 3 cases the operation was repealed on account
