7. In the Native States shown in Appendix II there were 108,477 persons
primarily vaccinated, against 109,028 in the previous year and 128,973 in
1917-18. The annual average number of successful cases for the triennium was
111,098 against 142,501 in the preceding triennium. The percentage of success
in which the results were known was 98.55 against 98.61 in 1918-19 and 98.46
in 1917-18. Re-vaccinations numbered 3,506 against 3,919 in the previous year
and 10,693 in 1917-18. The success rate excluding unknown results was 68.83
and the percentage of unknown results 55.63.
The total number of persons primarily vaccinated including those in Native
States therefore amounted to 719,527 and the total of re-vaccinations to 110,889
against 709,568 and 83,114 in 1918-19.
8. The quality of lymph supplied was on the whole good ; animal lymph was
used in Presidency Circle, Bombay, and human lymph in some Native States
attached to Gujarat Registration District. The results of the different kinds of
lymph used are given in the following table :—

The cause of the low percentage of success in Bombay City as reported by
the Superintendent of Vaccination was due to the deterioration of glycerinated
lymph stock during the hot weather, which resulted in an unusually large
number of unsuccessful cases during the months of April, May, September,
October and November 1919. Attempts have since been made to improve the
stock.
9. During the year 1919-20, 1,491,325 doses were issued from the
Belgaum Vaccine Institute showing a decrease of 5,295 as compared with the last
year. The decrease in the issue of doses this year was owing to the reduced
demand from Military Medical Officers. The details of issues for the last three
years are as follows :—

The case and insertion success rates were 99.58 and 97.19 respectively against
99.68 and 97.64 in 1918-19 and 99.77 and 98.05 in 1917-18.
The total expenditure of the Institute amounted to Rs. 59,089-5-8 against
Rs. 42,446-12-4 in the previous year. The increase in expenditure was due to the
annual increments in pay of the Director and his staff and also to the increased
price of grass and grain food for calves, and to the purchase of ice
necessitated by the break down of the cold store for a greater part of the year.
The net expenditure after deducting sale-proceeds was Rs. 27,378-12-5 against
Rs. 7,765-3-10 in the previous year. The average cost per dose of vaccine
manufactured came to 8.06 pies and the cost per dose despatched worked out at
9.47 pies.
