May 31, 2009 (Pentecost, at the Vigil)
Today’s Readings (text):
- Ezekiel 37:1-14 or other
- Ps 104:1-2, 24, 27-30, 35
- Romans 8:22-27
- John 7:37-39
Several alternatives for the First Reading can be found in the lectionary for the Pentecost Vigil, such as the story of the Tower of Babel from Genesis 11, which I retold on this site, here. However, I chose the readings above because of a recent discovery in medicine.
As you may know, the vaccine for tuberculosis, once quite effective, has stopped working, and this terrible lung disease takes the lives of about 1.7 million people every year.
We hear today, if you did the reading from the book of Ezekiel, that elephant bones are brought back to life. Before the bones come back to life, though, the prophet is ordered to walk among them and prophesy to them:
Then [the Lord] said to me: Prophesy over these bones, and say to them: Dry bones, hear the word of the Lord! Thus says the Lord God to these bones: See! I will bring spirit into you, that you may come to life. I will put sinews upon you, make flesh grow over you, cover you with skin, and put spirit in you so that you may come to life and know that I am the Lord.
So, Ezekiel does this and God brings life back into the bones, sending his spirit into them and renewing them, as we hear in the psalm reading. It is one of the most amazing miracle stories in the Old Testament.
Recently, scientists at Vanderbilt University have found what might be a way to revive the tuberculosis vaccine. Douglas Kernodle, M.D., associate professor of medicine (along with colleagues around the world), thought the vaccine had stopped working because it had become too “wimpy,” the online journal ScienceDaily reported.
Scientists hypothesized that the vaccine had evolved, acquiring traits in its genes that made it less potent, no longer causing the same level of immune response when it was given to humans. But whatever the cause, it was not nearly as effective at causing the production of antibodies against the real disease of tuberculosis.
When scientists took away these traits, using genetics, they produced what they thought would be a more effective vaccine, but still, it seemed not to regain its initial effectiveness. This is how things work—in science and in the elephant graveyard. If you have patience and keep at it, though, just as Ezekiel did, the Lord will send out his spirit and bring renewal and new discoveries.
Dr. Kernodle also kept going in his research to discover the underlying mechanism: it wasn’t that the vaccine was weaker, but rather, he said, it had become better at producing antioxidants, chemicals that suppress the normal immune response. If the immune response is suppressed, antibodies against the real disease don’t get produced as much, and the individual may not be immune to the disease.
Now that scientists know what caused the loss of effectiveness, they can reduce the bacterium’s ability to produce these antioxidants using molecular methods. The resulting vaccine bacterium has proven much more effective in mice, and the technique of altering the antioxidant capacity may lead to more effective vaccines against other diseases, such as HIV and malaria, we hope.
Without our training in molecular genetics and medicine, none of these discoveries would be possible. Suffering of millions of people would have no chance of being alleviated. That long-term study on our part is like Ezekiel walking up and down, prophesying to the bones. It doesn’t do any good until God sends his Spirit. God’s Holy Spirit brings to these scientists—and to you and me—certain abilities and gifts, and we continue to work to show love to our fellow human beings, acting as sort of God’s hands and legs (and mind) on Earth.
