The average number of primary and re-vaccinations of the triennial
period under review was 1,024,839 and 88,781 against 944,762 and 40,310 of
the previous three years. Thus there was a rise in the primary operations by
80,077 and in the re-vaccination by 48,471.
The increase in the number of primary operations and also in the number
of re-vaccinations is due partly to the more settled political aspect of the
country, the political unrest and active interference with the work of the vacci-
nation staff mentioned in the Triennial report for the years 1920-21, 1921-22
and 1922-23 having largely subsided.
The chief reason, however, was the wide spread epidemic of small-pox in
Orissa and in several of the districts of Bihar during the last two years.
Lieutenant-Colonel W. C. Ross, I. M. S., Director of Public Health, in his
report for 1923-24 predicted the probability of an increase in the prevalence of
small-pox during the next two or three years, and that there was likely to be
a severe epidemic of this disease in 1926-27. This forecast has so far "proved
to be correct and there is already evidence of this disease developing into a
serious epidemic this year, unless strong action is taken to adequately pro-
tect the people by means of vaccination. Primary vaccination only protects
for a limited number of years, and to reduce these annual epidemics of small-
pox, secondary vaccination must be made free and compulsory.
The percentage of successful operations out of the total number performed
during the last three years has been as follows :—
1923-24
1924-25
1925-26
97.96
97.42
93.20
Patna Division.
3. Vaccination in disrticts—The average number of operations performed in
this division during the triennial period has
decreased by 3,981 as compared with the
previous period. Shahabad District showed a decrease of 11,210. The districts
of Patna and Gaya showed increases of 1,072 and 6,157 respectively.
Tirhut division.
In Tirhut division, there was a rise of 35,551. The average number of
operations in each of the districts of this
division was more than that of the previous
three years. The most marked rise was in the district of Saran (19,519).
Bhagalpur Division.
The average number of vaccination operations performed in Bhagalpur
Division during the triennial period under
review was 243,754 as compared with
215,852 of the previous three years. Thus there has been a marked rise of
27,902 in the number of operations performed. The largest rise was in the
district of Monghyr (10,587) followed by Santal Parganas (9,903). There
was a decrease in the district of Purnea (1,376).
Orissa Division.
Orissa returns show an increase of 23,615 operations. The increase was
shared by all the districts with the exception
of the district of Cuttack which recorded a
fall in the average number of operations by 5,481.
3
Chota Nagpur Division.
In the five districts of Chota Nagpur, there were increases in the average
number of operations performed during the
triennial period under report, amounting to
45,461. In Manbhum, 16,833, Ranchi, 12,394, Hazaribagh, 8,653, Singhbhum,
5,223 and Palamau, 2,358.
4. Vaccination in Towns and compulsory areas.—During the triennial
period under review, the Vaccination Acts were extended to the Jharia Mining
Settlement in the district of Manbhum.
Statement VII shows the details of Municipal Vaccination from which
it appears that in Bihar, Muzaffarpur, Hajipur, Darbhanga, Kendrapara,
Daltoaganj and Chakradharpur, the work has been unsatisfactory.
5. Work done in the Native States under the supervision of the Political
Agent and Commissioner.—During the triennium under report, the number of
vaccination operations performed in the Native States is as follows :—

6. Protection of infants.— During the year 1925-26, 1,063,708 children
were available for vaccination. Of the available children 356 per thousand
were successfully vaccinated against 346 per thousand of the previous year.
Protection of infants in municipalities is shown separately in Statement
No. VII. The number of children available for vaccination was 31,282 of this
570 per mille was successfully vaccinated against 433 per thousand of the
previous year.
7. Incidence and Mortality of small-pox.—The death-rate from small-pox
during the year 1925-26 was 0.67 in the province against 0.24 of the previous
year and 0.23 the average of the last five years.
Patna Division.
The death-rate from small-pox in the district of Patna was 0.49
against 0.13 of the previous year and
0.71 the average of the last five years.
The districts of Gaya and Shahabad recorded rates of 0.46 and 0.16 respec-
tively, as compared with quinquennial rates of 0.23 and 0.19 respectively.
Tirhut Division.
The mortality from small-pox in the Tirhut division was 0.34. The
districts of Champaran and Saran recorded
rates of 0.65 and 0.50 respectively while
Muzaffarpur and Darbhanga returned the rates of 0.24 and 0.12 respectively.
Bhagalpur Division.
The mortality in the Bhagalpur Division was 0.15. Of the four districts
of this division, Purnea and Santal Par-
ganas recorded the highest rates (0.17)
followed by Bhagalpur (0.13). The district of Monghyr recorded a rate of
(0.11). The quinquennial rates of the districts of Monghyr, Bhagalpur,
Purnea and Santal Parganas were 0.15, 0.28, 0.32 and 0.11 respectively.
Orissa Division.
The mortality from small-pox (2.85) in Orissa was higher than that
of the other divisions of the province.
The district of Puri recorded the highest
rate (7.21) followed by Cuttack (2.50) and Balasore (1.71).
4
Chota Nagpur Division.
The rate of mortality from small-pox in the Chota Nagpur Division (0.32)
was lower than that of the other divisions
of the province excepting only the Bhagal-
pur division. Of the five districts of this division, the district of Singhbhum
recorded the highest rate (0.52). The lowest rate was recorded in Palamau
District (0.06) followed by Manbhum (0.32), Hazaribagh and Ranchi districts
(0.34).
8. Prevention of Small-pox.—Civil Surgeons and Assistant Directors
of Public Health are unanimous in attributing the opposition to vaccination
to be concerned more with the age of the child than with the operation
itself, and, in view of the strong popular prejudice which exists against the
vaccination of infants at an early age, I consider that it is desirable that
the Vaccination Act should be amended so as to raise the age for compulsory
vaccination to one year instead of six months.
I do not consider that small-pox can be effectively dealt with and stamped
out unless vaccination is made compulsory throughout the province, and I
would recommend that the Vaccination Act should be modified so as to extend
the age within which vaccination is required, to one year, and should be
generally enforced, and that vaccination should be free.
9. Inspection of work.—During the triennial period under review, the
Assistant Directors of Public Health inspected the number of children as
shown below :—
1923-24... ...
1924-25... ...

Experiments were also carried out to ascertain the cause of loss of potency
in the vaccine, and it was established that this loss was invariably associated
with the development of an acid reaction in the vaccine. This reaction was
developed most quickly in vaccine produced from adult animals, and as a result
of this experiment adult animals are no longer used in the production of
vaccine lymph.
During the year 1925-26, several experiments were carried out in the
rejuvenation of seed vaccine.
(1) Naguchis method of passage through rabbits' testicles. This method
was found to be effective but the quantity available was limited and no very
extensive trial of this method was made.
(2) Rejuvenation by passage through different species of vaccinifers
namely :—
(a) by vaccinating donkeys and calves alternately,
(b) by passage through rabbits, donkeys and then calves,
(c) by passage through buffalo-calves, children and then cow-calves.
Of these three latter methods, the passage through buffalo-calves, children
and then cow-calves proved to be the most effective, and it is proposed to adopt
this method in future.
13. The cost of the vaccination department.—The cost of the vaccination
department (excluding the cost of the Vaccine Depôt which is detailed in
paragraph 10 above) has been as follows during the last three years :—
1923-24...
1924-25...
1925-26...
Rs.
1,52,980
1,56,973
1,54,664
The average cost per successful operation was 2 annas 3 pies against
2 annas 7 pies of the previous triennium.
14. Personal.—In conclusion, I desire to bring to the notice of Govern-
ment the work done by the Assistant Directors of Public Health, Captain
Mitra, Dr. Mozumdar and Dr. Sebastian and latterly Dr. Das, in connection
with the inspection of vaccination and the supervision of the vaccination staff.
Dr. Sebastian has in addition held charge of the vaccine lymph depôt at
Namkum. Dr. C. N. Banerji, the Superintendent of the Vaccine lymph,
depôt has also worked hard and well.
