Of the 133 adult visitors to the Smallpox Hispital, 115 were,
before admission, re-vaccinated or had had previous attacks of
Smallpox, and of these none sickened; whereas of the 18 adults
vaccinated in infancy, who refused re-vaccination, 1 sickened
(5.5 per cent.).
In tabular form these results show up clearly:—
| Vaccinated | Under 10 years | 727 (6 sickened). | |
| 10 years and over. | 2184 (88 sickened). | ||
| Re-vaccinated or had previous Smallpox attack. | Under 10 years. | 0 (0 sickened). | |
| 10 years and over. | 568 (5 sickened). | ||
| Unvaccinated | Under 10 years. | 73 (12 sickened). | |
| 10 years and over. | 37 (9 sickened). | ||
| Vaccinated during quarantine | Under 10 years. | 109 (6 sickened). | |
| 10 years and over. | 3 (3 sickened). | ||
| Re-vaccinated during quarantine. | Under 10 years. | 99 (1 sickened). | |
| 10 years and over. | 1254 (11 sickened) | ||
| Total 5054 | Vaccinated (including those re_ vaccinated in quar antine). | 4264 (106 sickened) | 2.5% |
| Re-vaccinated or had previous at tack of Smallpox.) | 568 (5 sickened) | 0.9% | |
| Un-vaccinated (in cluding those vaccinated in quartine). | 222 (30 sickened) | 13.5% | |
In other words, of those persons who were, by vaccination, revaccination,
or a previous attack of Smallpox, protected (partially
or wholly), 2.3 per cent. contracted Smallpox, as compared with
13·5 per cent. of those not so protected.
An unprotected person in Lambeth Borough ran, during the late
Epidemic, 6 times as much risk of contracting Smallpox as a protected
person.
Taking the full totals, it is seen that of the 4944 protected
(partly or wholly) persons (adults and children), 120 sickened on
exposure to Smallpox, i.e., 2·4 per cent,; whilst of the 110 unprotected
persons (adults and children), 21 sickened, i.e., 19·1 per
cent.
