Authorities. The statistics of Janjira and of Kolhapur and Southern Maratha
Country States are shown in Appendix II.
Changes amongst the
staff.
3. During the year under report there was no change in the Supervising
Officers except that Lieut.-Colonel J. H. McDonald,
M.B , C.M., I.M.S., was in charge of the Office of
Assistant Director of Public Health, Western Regis-
tration District, from 19th November 1921 to 31st March 1922, in addition to

Primary
vaccinations
(Appendix I, Statements I
and III).
4. During the year 1921-22, 581,366 persons were primarily vaccinated
against 544;307 in the previous year. In all Registra-
tion Districts there was an increase in primary vacci-
nations due to recovery in the birth rate from the
effects of unhealthy years of influenza and plague and
its consequence that more children were available for vaccination purposes.
Results in
primary
vaccinations.
5. Out of 581,366 vaccinations 522,965 or 89.95 per cent. were successful,
1,969 or 33 per cent. were unsuccessful and the
results could not be ascertained in 9.72 per cent. of
the cases. Owing to failure of the first operation 78
persons were operated on a second time. The percentage of success excluding
unknown cases was 99.62.
Age and sex.
6. Of the primary vaccinations 459,908 or 79 per cent. were of infants
under one year of age and 107,725 or 19 per cent. of
children between the ages of 1 and 6 years. 298,738
males and 282,628 females were primarily vaccinated or a proportion of 105
to 100.
Re-vaccinations ( Appen-
dix I, Statements I and III).
7. 92,377 persons were re-vaccinated against 111,599 in the last year
shewing a decrease of 19,222. Re-vaccination is not
popular in the absence of epidemic small-pox and the
year under review was with one exception (1915) the
lowest in fatality from that disease to which the decrease in re-vaccination is
attributable. The percentage of successful re-vaccination excluding unknown
results was 46.45 per cent. ; in 42 per cent. the results could not be
ascertained.
Vaccination in Native
States ( Appendix II, State-
ment I).
8. In the Native States shewn in Appendix II, 168,187 persons were
primarily vaccinated against 163,664. The number of
successful cases was 164,832 or 98 per cent. The
percentage success excluding unknown was 99.44.
Re-vaccinations numbered 6,985 against 7,892 in the
previous year. The success rate excluding unknown was 70.94 and the
percentage of unknown cases was 23.44.
The total number of primary vaccinations including those in Native States,
therefore, amounts to 749,553 and the total of re-vaccinations 99,362.
