Twice, Never Scabbed

At my current age, old as dirt, have received multiple vaccines.

Seventy years worth. Did you know in 1796 Edward Jenner observed that milkmaids who were exposed to cowpox experienced a milder case of smallpox? He developed a method of arm-to-arm inoculation; a small amount of pus from one person’s blister was inoculated into the arm of another.

In my day, the 1950s, they used a bifurcated needle dipped in the vaccine solution then pricked the skin multiple times. The opaque pustules formed a scab that eventually fell off, leaving the skin pock-marked.

Twice, never scabbed.

(Bivalent COVID-19 vaccine, done.)
