Among those already artificially immunized, by inoculation or vaccination, who presented themselves for vaccination and so became included in these statistics, 15% were females, and 85% males. In the comments on Table 1 it was pointed out that this immune class was almost wholly over 6. The disproportion of the sexes may be caused to some extent by the reluctance of older girls and women to present themselves for vaccination, but the inference can not be escaped that the older method, inoculation, was less used for females than for males, presumably because of a lower value being set upon the life and comfort of females. In contrast, the number of girls under six vaccinated in this campaign somewhat exceeded the number of boys. This may be due to an increasing relative value set upon the lives of girls by their parents, or by the vaccinators, but is quite probably more due to the fact that in this campaign vaccination was done free, while the customary charge made by the old-style practitioners of inoculation amounted to two days wages at common labor. When protection can be had for nothing the girls are immunized. |
