Common appearances after Vaccination
Categories: Infectious Diseases
For a day or two nothing unusual
should appear. A few days after that, if it succeeds regularly, the skin
will become red, then a pimple will form, and on the pimple a little
vesicle or blister which may be plainly seen on the fifth or sixth day. On
the eighth day the blister (vesicle) is, or should be, plump, round,
translucent, pearly white, with a clearly marked edge and a depression in
the center; the skin around it for a
out half an inch is red and swollen.
This vesicle and the red, inflamed circle about it (called the areola) are
the two points which prove the vaccination to be successful. A rash, and
even a vesicular eruption, sometimes comes on the child's body about the
eighth day, and lasts about a week; he may be feverish, or may remain
quite well. The arm may be red and swollen down as far as the elbow, and
in the adult there will usually be a tender or swollen gland in the
arm-pit, and some disturbance of sleep for several nights. The vesicle
dries up in a few days more, and a crust forms which becomes of a brownish
mahogany color, and falls off from the twentieth to the twenty-fifth day.
In some cases the several appearances described above may be delayed a day
or two. The crust or scab will leave a well-marked, permanent scar.
