Primary operations.
5. The number of primary operations rose from 94,032 to 120,772, showing
an increase of 26,740. The percentage of success
in primary vaccination was 95.8 as against 97.1
in the previous year. It ranged from 91.2 in Basim to 97.5 in Amraoti and
Buldana districts.
The proportion of population protected by primary vaccination was 43.2
against 34.6 in the previous year showing a satisfactory increase compared with
other provinces.
Re-vaccination.
6. The number of re-vaccination rose from 38,871 to 55,129. Percentage
of successful cases decreased from 23.1 in the
previous year to 17.2 in the year under report.
Increase in both primary and re¬
vaccination work explained.
7. The large increase in primary work is due
to the following causes:—
(a) Increased birth-rate, which was 50 per mille.
(b) To the famine, bringing an influx of unvaccinated population
from across the Moglai border.
(c) The vaccinators were able to get at children on famine relief works
more readily and perform a higher rate of work than going from village
to village.
(d) Use of lanolinated lymph.
The increase in re-vaccination was also due to causes (b), (c), and (d) men-
tioned above.
Lymph supply.
8. The year's work was started on September 15th with a supply of lanoli-
nated lymph obtained from Mysore, as it has
always been done for many previous years, and
afterwards kept up by calf-to-calf or arm-to-calf vaccination. Owing to famine
and scarcity of fodder, strong healthy calves could not possibly be obtained in
sufficient numbers to carry on calf vaccination, and the only way to carry on
vaccination was to do it by lanolinated lymph. To obtain this lymph in large
quantities that would be required from Mysore would have been too costly; so
to save expense and at the same time carry on efficient vaccination, I decided
in November to manufacture lanolinated lymph at Amraoti, and funds to carry
out this were sanctioned by the Resident in Secretary for Berar's letter No.
591, dated 10th February 1900, to the Commissioner, Hyderabad Assigned
Districts.
The cost of lymph obtained from Mysore to vaccinate 100 children was
Rs. 5-9-6, while we could manufacture the same quantity at Amraoti at a cost
of 4 annas and 2 pie. The lymph when manufactured was sent out to all
vaccinators as required, and the whole of the vaccination work since November
has been done by lanolinated lymph. The use of lanolinated lymph helped to
increase the amount of work done, as vaccinators had not to take vaccinated
calves from one place to another to carry on vaccination, which delayed the
work considerably.
The success in both primary and re-vaccination was lower than in the pre-
vious year. This is due to the lanolinated lymph, which contains proportionately
less vaccine than pure calf lymph.
The low success in re-vaccination is also due to the efficacy of primary
vaccination done in former years : more efficient the primary work, poorer will
be the re-vaccination, and vice versâ.
It will be seen that success in primary vaccination varies in different dis-
tricts. Amraoti and Buldana show 97.5, whereas Basim gives 91.2. This is
due to the lymph reaching Amraoti and Buldana quicker than Basim from
head-quarters, and therefore losing its efficacy to a certain extent.
Ages of those vaccinated.
9. Of the ages of those successfully vaccinated, 96,180 were under one
year, 14,285 between 1 and 6 years, and 5,324
over 6 years of age and adults. Out of 100
successful vaccinated cases, 83.1 were infants, 12.3 children between 1 and 6,
and 4.6 of other ages.
