year 1921-1922 among immigrants from Makran and Cutch who driven from
their own countries by famine were attracted to Karachi and Sind in search of
employment in the labour market. These people were mostly unvaccinated on
arrival. They returned to their homes on the resumption of normal
conditions.
In Aden, during the year 1922-1923, 45,865 primary vaccinations and
23,668 re-vaccinations were performed against 3,676 and 48 in the previous year,
this great increase in number being due to an epidemic of small-pox. In
addition to the ordinary male staff, female vaccinators were appointed to pay
house to house visits and to vaccinate as many women and children as possible.
Sanitary Inspectors also vigorously carried out vaccination in their respective
divisions while local men were also engaged and posted at the police stations
to vaccinate any unprotected persons brought in by the police. The A.D.M.S.
(and C.A.M.O.), Aden, reports as follows :—"It was obvious to me from the
returns of vaccinations in the past, that only children born in Aden had been
vaccinated and that, therefore, the large floating population of Aden recruited
by dhows and ships from Somaliland, and Kafilas from the interior must be
practically entirely unprotected; 20,000 doses of vaccine were cabled for, extra
vaccinators engaged and with the co-operation of all, the disease in epidemic
form checked."
The average number of successful cases during the triennium was
530,632 against 586,049 in the period 1917—1920, a decrease of 55,417. The
percentage of successful cases in which the results were checked was 99.66
against 99.62 in 1921-22 and 99.65 in 1920-21. The average annual number
of vaccinations performed together with the average annual success rate for the
last three triennial periods are shown below :—

The figures for the last triennium do not include the statistics of Janjira
and Kolhapur or of the Southern Maratha Country States, which now exercise
independent control of vaccination.
The percentage of unknown cases for the Presidency excluding Aden was
9.13 against 9.32 in the previous year while for Aden it was 99.15 against 72.71;
the average annual percentage for the triennium being 11.53 against 8.00 in the
previous treinnium. The high percentage in Aden is due to the nomadic
habits of the people who do not wait for results to be inspected.
Re-vaccinations. (Appendix
I, Statements I & III.)
5. 99,141 persons were re-vaccinated against 92,377 in 1921-22 and
111,599 in 1920-21. The annual average number of
persons re-vaccinated during the triennium was
102,421 against 100,247 in the preceding triennium
shewing an increase of 2,174. The number of successful re-vaccinations was
18,709 during 1922-23 against 24,705 in 1921-22 and 30,872 in 1920-21. The
average number of successful re-vaccinations was 24,762 against 29,680 in the
preceding triennial period.
Vaccination in Native
States. (Appendix II, State-
ment I.)
6. In the Native States shown in Appendix II there were 175,692 persons
primarily vaccinated against 168,187 in the previous
year and 163,664 in 1920-21. The average number
of successful cases was 149,927 against 111,098 in
the preceding triennium. Considering only those cases in which the results
were definitely ascertained, the percentage of success was 99.47 against 99.44
in 1921-22 and 97.75 in 1920-21.
Re-vaccinations numbered 8,665 against 6,985 in the previous year and
7,892 in 1920-21. The success rate excluding unknown results was 69.03 and
the rate of unknown results 25.47 per cent.
