NOTES AND STATISTICS ON VACCINATION IN BURMA
3. Total number of Persons Vaccinated.—The total number was 957,317
as compared with 805,872 in the previous year.
4. Operations Performed.—The total number of operations performed
during the year was 870,402 (primary 550,154 and re-vaccinations
320,248) as compared with 720,551 (primary 511,750 and re-vaccinations
208,801) in the previous year—an increase of 149,851. An increase
in total operations was returned from 23 districts and a decrease from
18. Rangoon headed the list with an increase of 58,591 operations
followed by Akyab with 25,565 and by Magwe with 23,405. In these
three districts there was a great increase in re-vaccination work as a
result of the presence of small-pox. In each place additional temporary
vaccinators were engaged and vaccination was pushed vigorously.
Prominent amongst districts in which increased work was recorded
were the Southern Shan States ( + 15,189), Pegu (+9,748), Shwebo
(+9,117), Toungoo ( + 6,848), Tavoy (+6,247), Lower Chindwin
( + 5,020), Pyapôn (+4,038), Salween ( + 3,213) and the Northern Shan
States (+3,146). In all these small-pox was more or less prevalent with
the result that people came forward for protection willingly.
Of the 18 districts from which a smaller number of operations was
returned, Sagaing District was the worst as no less than 5,764 fewer
were reported than in the previous year. The District Health Officer
explained the decrease as being due to the relative absence of small-pox
from the district, although 414 attacks with 77 deaths were recorded.
There is no doubt that the work was not pushed as it should have been.
In Upper Chindwin also 5,427 fewer operations were recorded than
last year. Here also the District Health Officer pleaded less small-pox.
This may have been true but a larger vaccination staff is required in
this district. A large reduction was also reported from Myingyan where
5,161 fewer operations were performed than in the previous year. The
decrease was more marked in re-vaccination than in primary cases
and undoubtedly the absence of small-pox in epidemic form was a factor
as only 19 attacks with two deaths were reported and only four villages
were affected, but the non-employment of an Inspector of Vaccination
throughout most of 1927 and the placing of Vaccinators on plague duty
were contributory causes. In Prome District 3,110 fewer operations
were recorded—all under re-vaccination.
In Sandoway there has been a continuous decline in vaccination
since 1924-25 :—

Various reasons have been given but as there is no Inspector, want of
supervision is probably the real one.
FOR THE YEAR 1927-28.

Statement I.
5. Primary Operations.—550,154 primary operations were recorded
in all the 41 districts of the Province or an increase of 38,404 over the
previous year's output. The largest increase was in the Southern Shan
States where 13,202 more operations were performed than in the previous
year. Next came Shwebo with an increase of 5,069 followed by Magwe
with an increase of 4,288. Prominent amongst districts with an appre-
ciable increase in primary vaccination were Toungoo (+3,779), Pegu
(+3,427), Northern Shan States (+3,397), Akyab (+3,232) and Pyapôn
(+3,130).
In only four of the 17 districts in which smaller numbers of primary
operations were recorded was there a large deficit—Upper Chindwin,
Myaungmya, Sagaing and Thatôn. In them 2,874, 2,757, 2,439 and
2,156 fewer operations were registered respectively than in the previous
year.
Statement I.
6. Re-vaccination.—320,248 re-vaccinations were performed as
compared with 208,801 in the previous year, an increase of 111,447.
As stated elsewhere in this report, the largest amount of re-
vaccination work was done in Rangoon where 82,992 operations were
performed as against 25,301 in the previous year—an increase of 57,691
operations. In Akyab District there was an increase of 22,333 and in
Magwe an increase of 19,117. Substantial increases were also returned
from the following :—Pegu (+6,321), Tavoy (+6,066), Shwebo (+4,048),
Lower Chindwin (+3,564), Toungoo (+3,069) and Salween (+2,154).
Large decreases were returned from Prome and Myingyan. In the
former a deficit of 4,861 operations was registered and in the latter
4,319. From Sagaing District a deficit of 3,325 re-vaccinations was
recorded and from Kyaukse and Upper Chindwin 2,682 and 2,553,
respectively.
Statement I.
7. Results of Vaccination.—Of the 550,154 primary operations 482,304
were successful as compared with 472,368 in 1926-27. Of 320,248
re-vaccinations 102,917 were successful as against 61,531 in the previous
year. The results of 26,807 primary operations were unknown as
compared with 22,924 in the previous year, leaving 41,043 failures as
against 16,458 last year. Of the total of 482,304 successful primary
vaccinations 140,728 were on children under one year of age and 252,996
on children of one to six years. The remaining 88,580 successful
primary vaccinations were on persons over six years of age.
The percentage of successes in primary vaccination of which the
results were known was 92.16 and in re-vaccination 39.88 as against
96.63 and 35.97 respectively in the previous year.
The highest successful rate in primary vaccination (99.68) was again
recorded in Tharrawaddy District. Prome which held the second place in
success rate last year retained its position with 99.37 per cent. Ma-ubin
came third with a rate of 99.24. A success rate of over 98 per cent
4
NOTES AND STATISTICS ON VACCINATION IN BURMA
was obtained in Pegu and Toungoo and over 97 per cent in Rangoon,
Amherst, Myitkyina and Northern Shan States Districts. Over 95 per
cent. was obtained in Myaungmya and Salween and over 90 per cent in
the districts of Hill District of Arakan, Kyaukpyu, Bassein, Henzada
Minbu Magwe, Pakôkku Hill Tracts, Myingyan, Bhamo, Katha and
Upper Chindwin. The lowest success rate (67.04 per cent) was
recorded in Mergui District.
8. Vaccination in Towns.—In 68 Municipalities and notified areas to
which the Vaccination Acts have been extended 173,690 operations were
performed, an increase of 76,394 over the previous year. The increase
was almost entirely made up of re-vaccinations as there were 73,510
more than last year. Of the total operations 49,299 were primary and
124,391 re-vaccinations.
A marked increase in primary vaccination was recorded in the
following towns :—Rangoon ( + 900), Toungoo (+456), Thayetmyo
( + 320), Pegu) + 304), Bassein ( + 299), Akyab (+ 271), Mawlamyain-
ggyun (+ 208) and Pakôkku ( + 204).
A large decrease took place in Mergui Town where 720 fewer
operations than last year were recorded. Mandalay came next with a
deficit of 335 and Pyapôn with 321. Deficits of over 100 were returned
from Shwedaung, Kyônpyaw, Henzada, Kyaiklat and Moulmein, Among
these five towns the record of Kyônpyaw was particularly bad. In a
population of 6,884, only 90 persons were vaccinated during the year as
against 231 last year. As 150 births were recorded it is obvious that the
Vaccination Acts are not being enforced and that there must be a growing
population of unprotected children. Unless adequate measures are taken
an epidemic of small-pox is inevitable sooner or later.
There was an increase in re-vaccination work in 42 towns and a
decrease in 24.
Out of a total of 124,391 re-vaccination cases recorded in the
different towns in the Province nearly three-fourths were done in
Rangoon. Appreciable increases in re-vaccination were recorded in
Akyab ( + 4,311), Pegu ( + 2,228), Toungoo ( + 2,008), Syriam ( + 1,001),
Taungdwingyi ( + 802), Meiktila (+723), Insein ( + 627), Moulmein
( + 627), Henzada (+617), Mergui ( + 551), Pyapôn ( + 528), Pyinmana
(+492), Thayetmyo (+470) and Tavoy (+ 319). Large decreases were
recorded in Prome (—463), Paungdè (—291), Bassein (—265), Mônywa
(—260) and Myingyan (—200).
9. Results of Vaccination in Towns.—43,735 primary operations, or
93.41 per cent. and 43,954 re-vaccinations or 48.14 per cent. were
successful as against 94.78 and 41.91 per cent. respectively last year.
FOR THE YEAR 1927-28.
5
Cent per cent successes in primary cases were reported from 17
places—Akyab, Tharrawaddy, Thônzè, Letpadan, Gyobingauk, Minhla,
Nattalin, Insein, Paungdè, Kyônpyaw, Myanaung, Myaungmya, Wakèma,
Ma-ubin, Kawkareik, Shwegyin and Nyaung-U and in eight towns the
percentage of successful operations were over 99 per cent. Between 95
and 99 per cent. of successes were returned from eleven towns. The
lowest percentage in primary cases (59.79) was recorded in Lashio.
In re-vaccination cent per cent. successes were obtained in Akyab,
in Bassein 87.79 per cent, Shwebo 81.03, Ngathainggyaung 78.95,
Pyu 75.93 and Taungdwingyi 70.47.
Appendix B
10. Infant Vaccination.—It is possible to show by an estimation of
the number of infants available for vaccination in the various towns after
making due allowance for infantile mortality that a large number of
infants are not vaccinated at the time it becomes compulsory. In fact,
the Vaccination Acts are not properly enforced. The result is that
many children escape vaccination altogether and add fuel to the fire
when small-pox breaks out. The position in Kyônpyaw has already
been commented upon in paragraph 8 but similar conditions though in
less serious degree exist in a number of Municipalities.
Statement
III.
11. Dispensary Vaccination.—Vaccination was done in dispensaries in
18 districts only. 9,230 operations were performed as against 5,185
operations in the previous year, or an increase of 4,045. As in the
previous year the bulk of dispensary vaccination work was done in
Myitkyina District where 4,982 operations were performed as against
3,121 in 1926-27 or an increase of 1,861. Other districts which returned
a large increase were the Northern Shan States (+790), Upper Chindwin
(+337), the Southern Shan States (+258) and Mandalay ( + 252).
12. Jail Vaccination.—In the Jails 34,867 prisoners were vaccinated.
Of these 1,370 were primary operations and 33,497 re-vaccinations. Of
the primary 1,110 were successful and of re-vaccination 17,834 yielding
a success rate of 81.02 and 53.24 per cent respectively.
Summary
Statement
No. I.
13. Vaccination by Private Practitioners.—These performed 3,443
operations of which 253 were primary and 3,190 re-vaccinations. 229
primary operations and 871 re-vaccinations were successful. The results
of 12 primary and 1,471 re-vaccinations were unknown—the success
rates recorded in known cases being 95.02 and 50.67 per cent
respectively.
14. Steamer Vaccination.—Under the provisions of section ° of the
Burma Vaccination Law Amendment Act of 1909, 44,937 labourers
landing at the Port of Rangoon were vaccinated by the Corporation
Vaccination Staff under the supervision of the Port Health Staff as
against 49,763 in the previous year. The results are unknown.

Statement V.
15. Verification Work of Inspecting Officers.—Of the total number of
877,744 persons vaccinated the results of 74,374 or 8.74 per cent were
inspected by District Health Officers and Assistant District Health
Officers as against 8.80 per cent in the previous year. Inspectors of
Vaccination and other Inspecting Officers verified the results of 286,874
or 51.72 per cent of primary cases and 152,078 or 47.07 per cent of
re-vaccinations. Dr. Ba Than Chain, District Health Officer, Tavoy,
inspected 66.16 per cent of primary operations and 40.41 per cent of
re-vaccinations and the District Health Officer of Upper Chindwin,
Lieutenant P. Bell, I.M.D., inspected 42.35 primary operations and 39.00
re-vaccinations, but in many districts a very small amount of verification
work was done by District Health Officers. The Inspectors of Tharra-
waddy and Tavoy Districts. each inspected over 75 per cent of primary
cases in addition to 42'43 and 67.68 per cent of re-vaccinations
respectively. Over 70 per cent of primary cases and over 54 and 41 per
cent of re-vaccinations were checked by the Inspectors of Kyauksè and
Amherst Districts respectively. On the other hand, in Thatôn where
two Inspectors are employed only 44.81 per cent of primary cases and
36.92 per cent of re-vaccinations were checked.
Statement II.
16. Cost of the Department.—The total cost of the Department was
Rs. 4,03,228-12-3 as against Rs. 3,86,245-10-1 in the previous year or an
increase of Rs. 16,983-2-2. This increase was mainly due to increased
expenditure under " Pay of Establishment" consequent on the appoint-
ment of a whole-time Director and on annual increments drawn by the
employees.
The average cost of each successful vaccination was Rs. 0-11-1 as
against Rs. 0-11-7 in the previous year.
17. Small-pox Inoculation.—Inoculators were discovered in Prome,
Myaungmya, Pyapôn, Toungoo and Southern Shan States. In the first
four districts both inoculators and inoculated persons were prosecuted
and punished with fines ranging from Rs. 10 to Rs. 20 and in some
cases convicted inoculators were sent to prison.
18. Prosecution under Vaccination Acts.—427 prosecutions for
infringement of the Acts were launched in Hanthawaddy, Myaungmya,
Amherst, Mergui and Tavoy Districts and the convicted were punished
with fines ranging from Re. 1 to Rs. 10. Most of these prosecutions
took place in Myaungmya and Amherst Districts.
19. Work of the Vaccine Depôt, Meiktila.—A hostel for students
undergoing training has been built and a small laboratory for testing
lymph bacteriologically has been opened. A gas plant for the laboratory
and an ice-chest for storing lymph at a temparature below—10°C. of the
pattern used at the Government Vaccine Depôt, Bandoeng, Java, have
FOR THE YEAR 1927-28.
7
been installed. Since June bacteriological tests have been done at the
Depôt instead of at the Harcourt Butler Institute of Public Health,
Rangoon. An electric pump for raising water from the lake has been
put in and further improvements are under consideration.
Output of Lymph.—387 cow-calves and 10 buffalo-calves were success-
fully vaccinated. 18 of the former failed to take or yielded lymph of
such poor quality that it had to be destroyed. The cow-calves gave an
average lymph yield of 29.62 grammes and the buffalo-calves 134
grammes. The following table contrasts the output and issue of lymph
during the year under report and the two previous years :—

It should be noted that a larger quantity of lymph was obtained from
a smaller number of calves. 219,196 doses were sold to the Health
Officer, Rangoon, the Burma Railway Co. and private persons, and the
balance was supplied free to local bodies and the Army. At the beginning
of the year lymph was prepared by Gins' phenol method, but after a series
of experiments glycerinated lymph was re-adopted and remained in use
for the rest of the year.
Finance.—The gross revenue earned from the sale of lymph and
calves was Rs. 10,090-12-0 as against Rs. 9,221-12-3 in the previous year.
The net expenditure of the Depôt was Rs. 30,213-12-6 as compared
with Rs. 22,430-3-6 in the previous year or an increase of Rs. 7,783-9-0
due to the appointment of a whole-time Director and to the increased
expenditure on account of drugs and instruments for the Depôt.
20. Training Class.—67 students comprising two Sub-Assistant
Surgeons, 18 Public Health Inspectors and 47 Apprentice Vaccinators
were trained in vaccination.
21. General Remarks.—Mr. G. H. Blaker, I.M.D., was in charge of
the Depôt throughout the year, except for a short period when he was
deputed to Madras to study the preparation of lymph at the King
Institute of Preventive Medicine, Guindy. During his absence
Dr. J. J. G. DaCosta, L.M. & S., Civil Surgeon, Meiktila, officiated.
U Thaw Zan acted as Assistant Director for the whole year.
