staff from 13 to 7 thereby leaving large areas without vaccinators'
service for long intervals. It is to be noted that the district in
question is subject to exploitation by unprincipled operators who use
live small-pox virus as vaccine, thus implanting the disease itself.
The saving to the District Local Board as a result of this economy
at the expense of human life and sickness amounts to Rs. 3,936
per annum.

5.    Necessary reductions in vaccination staff were the abolition of
the post of Municipal vaccinator for Tatta town from 1st August
1923 (G.R., G.D., No. 4107, dated 20th June 1923) and the reduction
of the large staff of 11 vaccinators (engaged during epidemic
small-pox in 1922) in Aden to 5.

Bhor State strengthened their staff by appointing a candidate
vaccinator.

Primary Vaccinations. (Appendix I, Statements I and III.)

6.    Compared with the preceding year, 1923-24 showed an
increase in births that would be expected to result in an increase
in the number of persons primarily vaccinated. On the other
hand, the vaccination figures from Aden show a large drop as the
unprotected persons available for vaccination became exhausted.
On the whole there is a slight decrease; the figure of primary
vaccinations for the year being 631,850 as compared with 633,602
in 1922-23.

Leaving Aden out of consideration the figures for 1923-24 compared
with those for 1922-23 show an increase (from 587,737 to 616,320)
in primary vaccination in all Vaccination Districts and this is
attributable to the prevalence of small-pox in the greater part of the
Presidency. Re-vaccination work also showed increase in all the
Districts except the Southern Registration District where there was
a slight decrease.

                        Results in Primary Vaccinations.

7.    Out of 631,850 vaccinations, 559,329 or 88.52 per cent. were
successful, 1,473 or .25 per cent. were unsuccessful and the results
could not be ascertained in 11.23 per cent. of the cases. Owing to
failure of the first operation 73 persons were operated on a second
time.

                                    Age and Sex.

8.    Of the primary vaccinations, 477,082 or 75 per cent. were of
infants under one year of age and 134,508 or 21 per cent. of children
between the ages of 1 and 6 years. By sex, 330,921 were males
and 300,929 females equal to a proportion of 109.97 to 100, a
preponderance of males rather greater than shown in births regis-
tered (108.52 to 100).

      Re-vaccinations. (Appendix I, Statements I and III.)

9.    112,268 persons were re-vaccinated against 99,141 in the last
year showing an increase of 13,127. The percentage of successful
