            T. CHICHELE PLOWDEN, ESQ., C.S.,

                              Commissioner, Hyderabad Assigned Districts.

                                                Dated Amraoti, the23rd May 1891.

SIR,

In accordance with the orders of Government of India, No. 28—1579-95,
dated the 15th July 1887, I have the honour to submit the statistical returns of
the vaccination department for the year 1890-91 with brief notes thereon.

Statement No. I.—Particulars of
vaccination during 1890-91.

2. The total number of persons vaccinated during the year was 103,796, of
whom 57,595 were males and 46,201 females as
compared with 95,326 in 1889-90.

Each vaccinator performed on an average 2,471 operations in comparison
with 2,166 in the previous year.

The number of primary operations was 89,473 and re-vaccinations 14,323,
against 88,974 and 6,352 respectively in 1889-90.

In primary vaccination the percentage of success was 95.1, and in re-vac-
cination 29.5. For the previous year the ratios of success were 95.7 for primary
and 26.8 for re-vaccination.

In all 89,351 successful operations were performed against 86,914 in the
previous year, or an increase of 2,437 operations, notwithstanding that in
1889-90 two additional vaccinators were temporarily engaged in the Melghat,
where 1,392 cases were successfully operated on.

The percentage of the population successfully vaccinated was 36.8 per 1,000
as compared with35.4 for the previous year and 35.6, the average of the previous
five years.

There has thus been a satisfactory increase in the number of successful
operations, also in the average number of operations performed by each vacci-
nator and in the number of persons protected per 1,000 of population.

The slight fall in the percentage of success in primary vaccination may pos-
sibly be connected with the substitution of animal lymph direct from the cow
for arm-to-arm vaccination, as all the vaccinators were not equally expert in
animal vaccination.

Of the total number of successful primary operations, 73,059 were performed
on infants under one year of age; 11,028 on children over one and under six
years old; and 1,032 on persons over six years and adults.

Thus, out of every 100 persons successfully vaccinated, there were 85.8 in-
fants; 12.9 children between one and six; and 1.2 of other ages.

The percentage of the estimated births protected was 75.7 against 71.9
in the preceding year. Calculated on the total births registered during 1890, the
percentage of births successfully vaccinated was 71.5.
