Both the primary and revaccinations
decreased in Birbhum, Midnapur and
Pabna. In the Asansol Mining Settle-
ment, Bankura and Hooghly while the
primary vaccinations increased, there
was a reduction in the number of revacci-
nations. The reverse was the case in 24-
Parganas, Murshidabad, Jessore, Raj-
shahi and Jalpaiguri. The remaining
17 districts showed an increase both in
primary and revaccinations. In Burd-
wan, the Asansol Mining Settlement,
Birbhum, Bankura, Hooghly, Howrah,
24-Parganas, Nadia, Dinajpur, Rang-
pur,
Pabna,
Dacca,
Mymensingh,
Faridpur, Bakarganj and Chittagong
the line of least resistance was followed
with the result that primary vaccina-
tions exceeded revaccinations, even
though the smallpox epidemic in at least
six of these districts was more prevalent
in 1928-29 than what it had been in the
previous year. It is unfortunate that in
these districts the importance of revacci-
nation as an essential factor in con-
trolling smallpox epidemics was over-
looked by the local sanitary authorities,
but I trust that this laxity will not be
repeated in future.
(d) The increase in the number of
vaccinations wherever it has occurred,
has been due to the presence of smallpox
in an epidemic form, which is the only
stimulus for the people to get themselves
vaccinated. The decrease has been
ascribed by the District Health Officers
to various causes, chiefly the compara-
tive freedom of the district from small-
pox during season time, the presence of
malaria affecting both the vaccinators
and the persons to be vaccinated, the
paucity in the number of vaccinators
employed, the insufficient supervision
exercised by the Sanitary Officers due to
their being very busy with anti-cholera
work, and to a certain extent by the
obstruction caused by anti-vaccination-
ists, quacks and conscientious and
religious objectors. More attention is
said to have been paid to mass revacci¬
nation to suppress local smallpox epi-
demics and hence no time was left to
vaccinators to carry on their normal
work on primary vaccination in many
districts.
5. Vaccination in Municipalities.—
(a) 942,697 operations of which 270,156
were primary and 672,541 revaccina-
tions, were performed in the present
triennium against 556,406, 223,180 and
333,226, respectively, in the previous
triennium showing a net increase of
386,291 in total, 46,976 in primary and
339,315 in revaccinations and an aver-
age annual increase of 128,764, 15,659
and 113,105, respectively, in the trien-
nial period under review.
(b) Both the primary and revaccina-
tions in 1928-29 showed an excess over
those of the previous year in the munici-
palities of Burdwan, Hooghly, Howrah,
24-Parganas, Nadia, Jessore, Khulna,
Rajshahi, Dinajpur, Jalpaiguri, Dar-
jeeling, Bogra and Bakarganj districts
and a reduction in those of Bankura,
Midnapur, Rangpur. Pabna, Dacca,
Mymensingh, Faridpur,
Chittagong,
Noakhali and Tippera. In the munici-
palities of Birbhum and Murshidabad
districts and in Calcutta, while more
primary vaccinations were performed
during the year under review, the num-
ber of revaccinations decreased; the
reverse was the case, however in those
of the Malda district.
