to 3121 during October, November and December. Of these
3961 vaccinations and re-vaccinations, 2668 were performed at
the persons' own homes (as required by the 1898 Act), and 1293
elsewhere (e.g., Vaccination Stations, etc.). Further, taking the
10,183 primary vaccinations performed by the Public Vaccinators
during the year (August, 1901, to August, 1902), and allowing an
average of 5 re-vaccinations to every 1 primary vaccination (a
small allowance), the total number of re-vaccinations performed
during the same period by the same Public Vaccinators may be
reckoned as (roughly) 50,000, i.e., a sixth of the population of
Lambeth. It is clear that the large number of vaccinations and
re-vaccinations performed in Lambeth must have had some influence
in stopping the spread of Smallpox.
" Contacts" and their Vaccination States.
The statistics in connection with the "contacts" dealt with during
the Epidemic are noteworthy. Of the 4182 direct "contacts," 3236
were adults and 946 children. Of the 3236 adults, 925 were
re-vaccinated forthwith ; 549 had already been done, or had had
attacks of Smallpox, previously; 40 were unvaccinated, and of
these 3 were vaccinated forthwith; and 1722 had been only
vaccinated in infancy. Of the 946 children, 109 (unvaccinated)
were vaccinated, and 208 (vaccinated) were re-vaccinated, forthwith;
whilst 73 were unvaccinated, and 556 had been only
vaccinated in infancy.
In this way, out of a total of 3236 adults of 10 years of age and
over, 37 were unvaccinated, and therefore unprotected, and of
these 9 sickened with Smallpox (24.3 per cent.); whilst of the
3199 vaccinated or re-vaccinated, and therefore partly or wholly
protected, adults. 100 sickened with Smallpox (3.1 per cent.). Of
the total 946 children under 10 years, 873 were vaccinated or revaccinated,
and therefore partly or wholly protected, and of these
13 sickened with Smalipox (1.5 per cent.); whilst 73 were unvaccinated,
and therefore unprotected, and of these 12 sickened.
116.4 per cent.).
Of the outside "contacts," 677 were adults and all vaccinated,
and of these 223 were re-vaccinated forthwith; 19 had already
been done, or had had attacks of Smallpox, previously; and
441 had been only vaccinated in infancy. All the 677
adults were protected partly or wholly, and of these 6 sickened
with Smallpox (0.8 per cent.). The 62 children (all vaccinated
in infancy) were all protected partly or wholly, and of these none
sickened.
