Report of the Medical Officer of Health.
During the year 1912, of 6,647 children whose births were
registered, 3,458 or 52.0 per cent. were successfully vaccinated,
compared with 56.3 per cent, in 1911, 56.1 per cent. in 1910, and
60.9 per cent. in 1909. This is again a decided decrease compared
with the five previous years, and is the lowest rate in the last 10
years.
The next Table shows the percentage of children vaccinated
to total births registered in the Borough, and in the vaccination
sub-districts for the year 1912, as well as for the 10 years 1902-1911.
The average for the 10 years is also shown on this Table.
Compared with 1911 there has been a decrease in the percentage
of successfully vaccinated in all the sub-districts, with the exception
of Putney. The greatest decrease occurred in Streatham, while
in the whole Borough there has been a decrease of no less than 4'3
per cent.
Compared with the decennial average there has been a decrease
in all the sub-districts, the greatest decrease having been in
Streatham, and the smallest in Putney.
422 infants died unvaccinated, a percentage of 63, compared
with 8.8 in 1911, 6.2 in 1910, and 5.9 in 1909.
Of the 2,767 infants remaining, eight or .12 per cent. were stated
to have been insusceptible of vaccination; 1,348 or 20.3 per cent,
in respect of whom certificates of conscientious objection were
received; 103 or 1.5 per cent. had vaccination postponed by
medical certificate, leaving 849 or 12.8 per cent. as removed, not
to be traced, or otherwise unaccounted for, compared with 11.4
in 1911, 13.6 in 1910, and 13.3 in 1909; while 459 or 6.9 per cent.
remained on the books as unvaccinated, compared with 3.6 in 1911,
3.3 in 1910, and 3.3 in 1909.
There has been an increase of 1.4 in the percentage of cases
removed, of 3.4 in the number of certificates of conscientious
objections received, and of 3.3 in the number of cases remaining
on the books as unvaccinated.
