The percentages include "unknown". Excess operations 1,006, 857 and
755, respectively, are excluded.
Percentage
of
success
excluding " unknown cases ".
6. The percentage of success, excluding "unknown," was 98.59 as against
98.83 in 1903-04 and 98.89 in 1902-03, whilst the
percentage of unsuccessful cases was 1.39, 1.24 and
1.17 respectively. These results are excellent and
compare favourably with those in England and Wales, where the percentage of
success for 1901-02 and 1902-03 was 98.6 and 98.4 respectively.
Percentage of " unknown
cases".
7. The percentage of "unknown cases" was 5.90 as against 6.26 and 5.92
in 1903-04 and 1902-03 respectively. The large
number of unknown cases habitually returned is partly
due to the fear of parents of having lymph taken
from their children's arms, and partly to indolence on the part of Vaccinators
and parents.
Infants successfully vac-
cinated as compared with the
number available, i.e., births
minus deaths under one year
of age.
8. The infants available for vaccination, after deducting the births from
the deaths under 1 year of age, amounted to 522,421,
of whom 390,971 or 74.84 per cent. were successfully
vaccinated excluding Native States and Aden as
against 363,038 or 79.99 per cent. in 1903-04 and
364,513 or 71.85 in 1902-03.
The ratio of infantile protection afforded during the triennial period under
report was 75.56 per cent.
The above figures are only approximately accurate, as the "unknown"
and ''unsuccessful" cases are not given by the Deputy Sanitary Commissioners
"under one year of age," moreover the registration of infantile deaths, is still
far from correct. The percentage protection afforded to infants connot therefore
be accurately recorded. The percentages for 1899-1900, 1900-01, 1901-02 were
78.29, 100.59, 76.56 respectively, and the triennial average 85.14.
Re-vaccination.
9. The total number of persons re-vaccinated in 1904-05 was 61,934, of
whom 26,884 were successful or 43.41 per cent. as
against 35,830 with 19,768 or 55.18 per cent. successful
in 1903-04 and 41,136 of whom 22,925 or 55.73 per cent. were successful in
1902-03. The percentages include "unknown". Excess operations 9, 2 and 5
respectively are excluded.
The average number of re-vaccinations performed during the triennium was
46,300 against 71,172 of the previous triennium.
There was a marked increase in re-vaccinations by 26,104 over last year due
to panic vaccination, chiefly in Bombay City during the small-pox epidemic of
1904-05. Compared with the population the amount of re-vaccination
performed throughout the triennuim was trivial, caused by indolence, apathy
and neglect of a secondary operation by the people themselves.
Percentage of successful
cases excluding ''unknown ".
10. The percentage of successful cases excluding
''unknown" was 79.12 against 80.15 in 1903-1904
and 82.78 in 1902-1903.
Percentage of "unknown
cases ".
11. The percentage of "unknown" cases was extremely high, 45.15 as
against 31.17 in 1903-1904 and 32.68 in 1902-1903,
the triennial average being 36.33 per cent. The
disinclination of the people to re-vaccination accounts
for the habitual small numbers operated on. It is only during epidemics of
small-pox such as occurred in the year under report that any marked increase
of re-vaccination occurs and that chiefly amongst a small section of the
upper classes.
Successful
vaccinations
per mille of population.
The very large average number of "unknown" cases amounting to 36.33
per cent. for the triennium is due to the neglect of people to return to the vaccine
stations for the purpose of having the results of their operation ascertained,
12. In 1904-1905 the total number of successful primary vaccinations of
children under one year per mille of population was
21.21 against 19.49 and 19.47 in 1903-1904 and
1902-1903 respectively. The triennial average was
20.0 as against 19.14 for the previous triennial period.
It would be more accurate and useful to compare the infantile protection
with the births minus deaths as returned by the Local Government Board,
England, but the figures are not available in this country.
