Vaccine

Latin vaccinus, from vacca “cow” because of

early use of cowpox virus against smallpox.

I remember the massive Sabin oral vaccine

for polio first developed by Jonas Salk.

Vaccines stimulate the production of antibodies

provide immunity against one or several diseases

using disease to treat without inducing disease.

“Our greatest responsibility,” said Dr. Salk Vaccine,

“is to be good ancestors.” We too

use our life to inoculate against life.

A 1963 poster featured CDC’s national symbol of public health, the “Wellbee”, who was encouraging the public to receive an Sabin Type-II oral polio vaccine in campaigns across the United States. (via Wikimedia)
