The steady improvement in infantile vaccination is a gratifying feature.
The percentage of successful infantile vaccination in 1928-29 to the registered
births varied from 25.2 in Gōdāvari, East to 72.0 in Madura District. Compared
with the previous year, 14 districts recorded increases and the rest decreases-
Details of infantile vaccination rates for individual districts are furnished in
Annexure A.
21. Vaccination in municipalities.—Excluding Karaikudi which was constituted
as a municipality in 1928-29, the number of operations performed during the
triennium under review in the remaining 81 municipal towns was 605,412 which is
a decrease of 3,179 cases compared with the previous triennium. Comparative
figures of individual towns for the last two triennia and also for the years 1927-28
and 1928-29 are given in Annexure D.
The municipalities which returned large increases in vaccination outturn in
the triennium under report were Madura (19,000 in round numbers), Calicut
(5,000), Trichinopoly and Kurnool (3,000 to 3,500), Coimbatore, Cuddalore
and Salem (2,000 to 3,000). Decreases were marked in Madras (19,600), Cannanore
and Rajahmundry (between 5,000 and 6,000), Mangalore (4,300), Chirala,
Negapatam and Cuddaph (2,000 to 3,200).
22. Although the triennial outturn shows a decrease of about 3,000 opera
tions, the number of vaccinations done in 1928-29 shows an improvement over
the previous year, an increase of over 22,000 cases having been recorded.
Forty-four municipalities returned increases whilst 35 returned decreases; as
regards the three remaining municipalities, the figures were stationary in two
and in the case of the third, viz., Karaikudi, comparison cannot be made as it
was constituted as a municipality only in 1928-29.
The towns which recorded large increases were Madras (+11,383), Calicut
(+7,084), Vizianagram (+1.871), Kurnool ( + 1,634) and Ellore (+1,225). Next

Absence of smallpox and less number of re-
vaccinations than in 1927-28.
Large number of postponements on account
of the prevalence of measles and non-
appointment of a substitute in the vacancy
of the female vaccinator on leave for a
month.
Frequent changes in the vaccination staff,
large number of postponements and result
of anti-vaccination propaganda.
Fall under revaccination as also anti-vacci
nation propaganda.
Indifference of work of first-class vaccinator
and the absence of a vaccinator on leave
for three months without a substitute.
Large number of postponements on account
of wide prevalence of influenza.
Frequent changes in the personnel of vacci
nation staff in Division II and the indiffer
ent work of the female vaccinator.
