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)
One was written by a believer, 1632 –
Dialogue Concerning the Two Chief World Systems –
really an argument between the Catholic Church
and Galileo, convicted of heresy for saying
that Earth is not the Universe’s center.
Galileo Galilei pushes away the Bible at his trial for heresy by the Inquisition in Rome in 1633. by Roberto Francesco Romolo Bellarmino
Beyond my physics, matter our exact opposite.
Anti-atoms, anti-solar systems meeting in mutual annihilation.
This dark morning I am a positron,
identical, but traveling an opposite path now.
Anti-universe, warped mirror. Something oddly familiar ahead.
Though we are now very far apart,
I feel connected to you again like
Einstein’s “spooky action at a distance” but
I have no scientific explanation for it –
no fear of the darkness of ghosts.

1633: Galileo Galilei was put on trial
for saying that the Earth revolves around
the Sun. We are not the center.
They knew better than God who seems
to have been the one who planned it.
[ Back in April 1633, Galileo agreed to plead guilty and was sentenced to an unlimited period of house arrest in his home in Florence for this offense. He gradually went blind and stopped looking to the heavens. It took until 1992 for the Catholic Church to formally admit that Galileo’s views on the solar system are correct. ]
