(b) Re-vaccination.—A total decrease of 640 operations by dispensaries
was due to no re-vaccination having been performed in His Majesty's House of
Correction, Bombay, as against 72 last year ; fewer operations performed in the
Ahmedabad Central Jail (1,278 as against 1,812 in the previous year) ; no re¬
vaccination in Bushire, and 8 as against 14 in the previous year for Sádra,
Mahi Kántha Agency.
The decrease in re-vaccination in Gujarát (1,076) was due to 534 fewer
re-vaccination in the Ahmedabad Central Jail and absence of famine relief
camps, wherein a large number of re-vaccination were performed last year.
In the Western Registration District the decrease (24) was trivial.
In Sind the causes of decrease (2,058) are attributed by the Deputy
Sanitary Commissioner to the unwillingness of the inhabitants of Sind to be
re-vaccinated unless owing to the pressure of a local epidemic they think they
are in danger of contracting small-pox. As contributory causes decrease was
noted in Karáchi District due to the inefficiency of the Tatta and Sujáwal
Vaccinators whose services had to be dispensed with. In Larkhána District
to the indolence of the Shewan táluka Vaccinator and in the Upper Sind Fron-
tier to the sickness amongst the Vaccinators of Thull and Káshmore.
In the Southern Registration District the decrease (2,035) is attributed by
the Deputy Sanitary Commissioner to one or all of the three following causes :—
(1) Failure on the part of the Vaccinator to visit the schools regularly.
(2) Want of co-operation on the part of the school master.
(3) Objections on the part of children and their parents.
In Bombay City the decrease (116) is attributed to want of control over
re-vaccination. The numbers fluctuate from year to year according to circum-
stances, eg, when small-pox becomes prevalent there is a good deal of panic
re-vaccination work performed as in the year 1900 when 31,168 re-vaccinations
were done. Re-vaccination is very much neglected in the schools, mills and
factories ; until primary and re-vaccination is enforced by law throughout the
City of Bombay and amongst the pilgrims-shipping, etc., the City must always
be exposed to epidemic small-pox.
Infants successfully vacci-
nated as compared with the
available number.
12. The number of infants successfully vacci-
nated, exclusive of Native States and Aden, was
363,038 or 79.99 per cent. of those available as
measured by proportion of infants vaccinated to the
births minus deaths under one year.
Results of primary vacci-
nation. Appendix I. State-
ments I and III.
13. From statements Nos. I and III it will be seen of 551,244 total primary

cent. (excluding unknown cases). The number of

The unknown cases were 34,549 or 6.25 per cent.
The number of excess operations or in which a second operation had to
be performed on account of failure of the first (not shown in the statements)
was 857 and are not shown in the above calculation.
Results in re-vaccination.
14. During the year 35,830 persons were re-vaccinated. In relation to
the population the number was trivial. The number
of successful cases was 19,768. In a very large
number of cases 11,167 or 31. per cent. the results could not be ascertained.
