Animal vaccination—Calf¬
to-arm.
24. Animal vaccination was performed in the Western Registration
District in 9 Municipal Towns and 38 villages. In
Bombay City, Coorla and Bándra. In the Central
Registration Districtin 29 Municipal Towns, 3 Canton-
ments and 429 villages. In the Southern Registration District in 2 Municipal
Towns, 1 Cantonment and 4,836 villages, and in the Sind Registration District in
1 Municipal Town, and 1 Cantonment. This method of vaccination although
popular is expensive and will eventually give way to vaccination with preserved
lymph. During the year 1,491 calves were inoculated. Of these 16 were
rejected on account of sickness, 21 were unsuccessful and 147 inoculated calves
were supplied to various bodies.
Preserved lymph.
25. Vaccination with preserved lymph, both lanolinated and glycerinated,
was carried out chiefly in the Southern Registration
District.
A temporary depôt has now been formed at Belgaum for the manufacture
of preserved lymph under the Superintendence of the Acting Deputy Sanitary
Commissioner Captain F. H. G. Hutchinson, I. M. S., through whose energy and
zeal this method of vaccination has been popularized in the Southern Registration
District. Arrangements are now being made to extend this method throughout the
Presidency. The scheme for a permanent depôt is still under the consideration of
Government.
Lanolinated lymph.
26. Captain Hutchinson reports—Lanolinated lymph—75,266 primary
vaccinations were performed in 1904-05 with a case
success rate "excluding unknown" (7.73 per cent.)
of 96.06 per cent. and an insertion success rate of 85.00 per cent.
The large percentage of unknown cases (5,825 out of 75,266) was chiefly
due to the indolence on the part of certain vaccinators. There were 8,804
re-vaccinations with a case success excluding "unknown " of 85.23 per cent.
and insertion success rate 72.58 per cent. The ratios of case and insertion success
in primary varied from 97.65 and 89.55 to 92.41 and 78.11 per cent. With
more experience there is no reason why vaccinators should not equal the standard
obtained by the best vaccinators with calf-to-arm or human lymph.
Glycerinated lymph.
27. "Glycerinated lymph" was commenced during the year under report.
There were 7,544 primary vaccinations, of which,
excluding ''unknown cases," the percentage of success
was 96.55. Unknown cases 5.27 per cent. Insertion success 87.55. These results
include the work of men in the course of training. As an example of the results
obtained by thoroughly trained men, viz. the Native State Vaccinators, the
percentage of success was 98.26 and insertion success 93.12 out of 2,217 primary
operations. There is every reason to anticipate an equal success rate for the
whole district when the vaccinators have been carefully trained and have had
more experience.
Arrangements are being made at the Depôt for the training of the Inspectors
and Vaccinators of remaining: districts.
Animal
Vaccine Depôt,
Belgaum.
28. The scheme for an "Animal Vaccine Depôt" for the manufacture of
preserved lymph still awaits the sanction of Govern-
ment. Experiments were continued throughout the
year by Captain Hutchinson both with lanolinated and
glycerinated lymph. The results were very satisfactory and show that chloro-
formed glycerinated lymph fulfils all the requirements and is preferable to lanoli-
nated vaccine. The details of results are given in paragraph 26. Lanolinated
lymph caused in many cases considerable inflammation, disturbance, ulceration,
glandular abscess and general vaccinia. It is found extraneous micro-organisms
invariably associated with lymph abstracted from the abdomen of the calf
flourish and multiply in lanoline vaccine, whereas in chloroformed glycerinated
lymph they are rapidly and completely destroyed. So far as experiments go
there is no doubt choice should be given to glycerinated vaccine.
Central Vaccine Depôt, Parel.
29. This depôt was occupied by the Superintendent of Vaccination, Pre-
sidency Circle, Bombay, on 31st March 1905. The
question whether Párel or Belgaum shall be chosen as
the locality for the manufacture of preserved lymph is still under the consideration
of Government.
