TRIENNIAL REPORT ON VACCINATION IN BURMA
the people to accept vaccination must have contributed to the result.
There was no improved organization of district staffs and if anything,
the supervision exercised over the work of the vaccination staff was
less perfect in many districts than in the past; yet each year of
the triennium under review produced results more favourable than any
of the previous years excepting 1919-20. The number of operations
(excluding dispensary vaccination) performed in 1920-21 and the two
succeeding years was 670,425, 650,140 and 697,829, respectively,
against 469,471, 469,574, 549,149, 492,008, 563,020, respectively,
in 1914-15 and the four succeeding years, while in 1919-20 the figure
was 839,079. The total operations and the successful vaccinations
for the triennium were the highest on record as can be seen from the
following table:—

2. Operations.—The increase is wholly derived from primary cases,
there having been a considerable fall in the aggregate of revaccinations.
Arakan, Pegu, Irrawaddy, Tenasserim and the Frontier divisions re-
corded an increase, while Rangoon, Mandalay and Border divisions
registered a decline, Arakan and Mandalay returning the largest
increase and decrease respectively. Districts showing a decrease are
Rangoon, Thayetmyo, Mergui, Pakôkku, Sagaing, Upper Chindwin,
Mandalay, Yamèthin,Putao and Myitkyina. The decrease in Rangoon,
Pakôkku, Sagaing, Mandalay and Myitkyina is wholly in revaccination
while that in Thayetmyo was all in primary vaccination. In other
districts the fall is noticeable in both primary and revaccination.
Including the 4,630 vaccinations performed in dispensaries the total'
operations for the province in 1922-23 amounted to 702,459. Of these
4,599 (primary 1,007 and revaccination 3,592) were returned by "other
agencies " leaving 693,230 operations as the output of 336 vaccinators
(2,063 per head) employed during the year.
3. Successful Vaccinations.—The only divisions which in the trien-
nium returned fewer successful vaccinations were Rangoon and
Mandalay but these showed an increase in primary vaccinations, the
deficit being entirely in revaccinations. Other areas in which a fall in
successful revaccination was observed were the Border and Frontier
divisions. Districts in which decrease in successful primary operations
was reported were:—
Hill District of Arakan (210), Tharrawaddy (8,438), Amherst
(1,982), Thayetmyo (4,063), Mergui (5,817), Lower Chindwin (1,277),
Upper Chindwin (889), Yamèthin (2,430) and Putao (1,247).
As in the previous triennium Henzada district easily heads the list
for successful primary vaccinations, there being a difference of nearly
20,000 cases between it and Thatôn which comes next in order.
A large increase in successful primary vaccinations was reported
from the districts of Kyaukpyu (16,455), Myaungmya (12,772),
Pyapôn (21,509), Thatôn (10,931) and Northern Shan States (15,489)
while increase in revaccinations is returned by Akyab (25,930),
