Triennial Report
ON
VACCINATION IN BURMA
For the years 1923-24 to 1925-26.
1. General Review.—As the various reasons for the increase in
vaccination work in the Province have already been detailed in my
Report for the triennium 1920-21 to 1922-23, it is unnecessary to
recapitulate in the present report; suffice to say that the marked
increase in the output of vaccination during the present triennium
(+383,401 cases) is due to those same incentives,—more especially to
outbreaks of small-pox which stimulated all concerned to push vaccination
and moved the general public to submit thereto as the best protection
from the disease.
The outbreak of 1923 still continues in many districts. The number
of recorded deaths from small-pox in 1923 was 2,846, or 0.26 per 1,000
of population. The death-roll was slightly lower in the following year,
in which 2,501 deaths (or 0'23 per 1,000 of population) were returned,
but rose again in 1925 when 3,852 deaths were recorded, every district
in the Province being affected by the disease. Myingyan District
suffered most with a total of 679 deaths, followed by Rangoon
with 630 deaths, Sagaing with 318 deaths, Pegu with 306 deaths,
Mandalay with 286 deaths, and Pakôkku with 217 deaths. The other
districts which recorded over 100 deaths were Meiktila (165), Thatôn
(159), Yamèthin (157), and Lower Chindwin (145).
With the spread of the disease and increase in deaths, the output of
vaccination in the Province rose proportionately. This is only to be
expected when the public awaits the onset of small-pox before
accepting vaccination, instead of having recourse to vaccination as a
means of small-pox prevention.
Universal vaccination, and re-vaccination,—so that all persons are
vaccinated at least twice in their lives would practically abolish small-pox
from the Province, thus preventing thousands of deaths annually, to
say nothing of saving many from permanent blindness and disfigurement.
For many years this disease has taken heavy, and needless, toll of the
2
TRIENNIAL REPORT ON VACCINATION IN BURMA
population. During the last ten years 1916 to 1925 over 20,000 lives have
been lost by this disease, and now at the close of 1925 the disease is
still spreading in many districts.
It is gratifying however to note that the importance of vaccination
and the prevention of inoculation is being recognized and that, led by
the District Councils of Tharrawaddy and Thayetmyo, most District
Councils have adopted the Vaccination Acts which have now been
extended to all districts in Lower Burma, with the exception of the Hill
Districts of Arakan, Kyaukpyu, Sandoway and Salween Districts. The
Acts have also been extended to four districts in Upper Burma (viz.,
Thayetmyo, Magwe, Minbu and Kyauksè) and to the Shan States,
while the Burma prohibition of Inoculation and Licensing of Vaccinators
Act has been extended to Pakôkku, Yamèthin, Sagaing, Mandalay,
Shwebo, Lower Chindwin, Upper Chindwin, Katha, Kyaukpyu and
Sandoway. It is hoped that before long it will be possible to extend
the Vaccination Acts to all areas under the control of District Councils.
Statement 1. 2. Total Operations.—The total number of operations performed
during the triennium under report shows an appreciable increase over
that of the previous triennium. The figures of the two periods being as
follows :—

2,401,795
2,018,394
+ 383,401
It will be noticed that there is an increase in both classes of
vaccination, but chiefly in re-vaccination, this possibly being accounted
for by the fact that small-pox was more severe during the present
triennium than in the past. Out of 41 districts, only 8 show a falling off
in the total output of vaccination, viz., Akyab (—28,750), Kyaukpyu
(-14,436), Bassein (-2,600), Amherst (-3,680), Toungoo (-2,220),
Yamèthin (-36,870), Myitkyina (-963), and Lower Chindwin (-7,517).
Rangoon shows the highest increase in the total output ( + 71,301
operations), followed by Southern Shan States (+36,215), Myaungmya
(+30,300), Myingyan ( + 28,295), Northern Shan States (+26,027),
Hanthawaddy ( + 23,925), Ma-ubin ( + 23,664), Sagaing (+22,094), and
Upper Chindwin ( + 18,572).
The districts which show an increase of over 15,000 cases in total
output were Pyapôn, Minbu, Pakôkku, Mandalay and Shwebo ; and of
over 10,000 were Pegu, Insein and Thatôn. The decreased total
output of over 36,000 in Yamèthin District, of over 28,000 in Akyab
District and of over 7,000 in Lower Chindwin District was due to the

fact that fewer re-vaccinations were done. In Yamèthin District
38,081 fewere-vaccinations were done as compared with the previous
triennium,—Akyab District 31,426 less, and in Lower Chindwin 12,495,
but in all these districts improvement in output of primary ,vaccination
is recorded.
Statement I.
3. Primary Vaccination.—In primary vaccination 28 out of 41
districts show an increase during the triennium. The districts which
recorded a large increase in the output of primary vaccination are
the Southern Shan States (34,769), Northern Shan States (26,452),
Myaungmya (24,232). and Hanthawaddy (11,618). The increase in all
these districts is commendable, especially in the Shan States where
many of the people are very backward and work has to be carried out
under most trying circumstances as regards travelling, distances from
headquarters to the scene of vaccination, etc. The prevalence of small-
pox in the States and the active assistance rendered by Government and
State Officials are the chief factors responsible for the increased work
done.
Other districts worthy of comment as showing an increase in the
output of primary vaccination are Rangoon (+5,573), Insein ( + 5,149),
Henzada (+7,134) and Mergui (+6,410).
The list of those showing a falling off in primary vaccination is
headed by Amherst District where 15,010 fewer cases were recorded as
compared with the figures for the triennium 1920-21 to 1922-23.
In this district, although the output during the present triennium
is actually less than that recorded in the former triennium, vaccination
shows signs of gradual improvement,—for the number of cases recorded
in the last year of the previous triennium (viz., 1922-23) was 13,188
cases, in 1923-24 it rose to 14,000, and, in the last year of the present
triennium (viz., 1925-26), the number of primary vaccinations performed
rose to 18;003.
The next district on the list in which a large decrease in primary
vaccination was recorded is Toungoo (—9,159). Here, however,
there was an increase in the number of re-vaccination cases recorded,
+6,939 re-vaccinations having been performed in excess of the number
for the previous triennium, so the net decrease in the total output was
only 2,220. Nevertheless the decline in primary vaccination is regret-
table. Here again the outbreak of small-pox was present as a stimulant
to re-vaccination during the three years of the triennium. In 1923 the
number of deaths from small-pox in the district was 16 ; in 1924 it was
53 ; and in 1925, 46 deaths were recorded. The average number of
cases vaccinated by a vaccinator in 1923-24 was 1,422 (or 119 per
month). In 1924-25 it was 1,325 (or only 110 per month), and in 1925-26
it was 1,649 per year (or 137 per month). The standard number of
cases demanded of a vaccinator per month is 200 cases as a minimum.
The Vaccination Acts of 1880 and 1909 have been extended since
4
TRIENNIAL REPORT ON VACCINATION IN BURMA
May 1924 throughout the area administered by the District Council, but
it does not appear that the rules framed thereunder for the proper
enforcement of the Act have yet been properly brought into effect.
Third on the list in which a decline in the output of primary
operations was reported in Kyaukpyu District. The falling-off in this
district was similarly due to the absence of small-pox during the years
1923 and 1924, only a few cases occurring in 1925, whereas the disease
had been present in the two previous years, especially in 1922 when 100
deaths from small-pox were reported. The output of vaccination in
that particular year was the highest on record during the last ten years.
Considering the lack of travelling facilities in this district and the
fact that vaccination is voluntary, the average number of operations
performed by each vaccinator per month was not so bad as in some
other districts. In 1923-24 each man vaccinated on the average 140
cases, the output rose to 161 per month in 1924-25, and in 1925-26
the average was 234 cases per month.
The other districts which show a large decrease in the amount of
primary vaccination are Thatôn (—7,472), Pakôkku (—5,597), and Bassein
(—5,489), but in the former two districts the decrease in primary cases
was more than compensated by an increase in the number of re-
vaccinations. In these districts, small-pox was more prevalent than it
was during the previous triennium, and wholesale vaccination and
re-vaccination were carried out. The falling-off in Bassein District is also
attributable to the relative absence of small-pox during the present
triennium.
Statement I. 4. Successful Primary Operations.—Consonant with the increase in
the output of primary vaccination work, the number of successful
primary operations also shows an increase of 143,584 during the
triennium under report. The same districts which showed an increase
of work also showed an increase in successful cases with the exception
of Thayetmyo District in which, although 409 fewer operations were
performed than in the previous triennium, the number of successful
cases recorded exceeds the previous figure by 81. The percentage
success rates recorded in this district in the two triennial periods
1920-21 to 1922-23, and 1923-24 to 1925-26 were 95.06 and 96.10
per cent. respectively.
The actual figures for successful primary cases in the Province
during the two triennial periods being for 1920-21 to 1922-23 1,394,637,
and for 1923-24 to 1925-26, 1,538,221. The success percentage of
the present triennium was 0.13 higher than that of the previous period.
The district from which the highest percentage of successful primary
vaccination was returned during the year 1925-26 was Tharrawaddy
(99.97), followed by Pyapôn (99.80), Henzada (99.68), Rangoon (99.65),
Ma-ubin (99.62), Lower Chindwin (99.60), Toungoo and Kyauksè (99.55),
