which may be useful in some other disease, “off label” in the pharmacolo­gists’ vernacular. An example of this off-label use is the steroid Dexamethas­one. It has been found to reduce death among critically ill COVID-19 patients.

It is a good idea to look outside the box, as we are constantly advised. But it is also a good idea to look inside the box as well.

Inside every hospital, for example, is a radiation department. Radiation is a medical tool universall­y used in cancer treatments.

Now comes word that radiation can save lives and cut hospital stays for COVID-19 patients. James Conca, a Tri-cities, Wash.,-based nuclear scientist, explains to me, “This treatment is critical because severe cases cause cytokine release syndrome, also known as a cytokine storm, causing acute respirator­y arrest syndrome, which is what kills.”

Dr. Mohammad Khan, associate professor of radiation oncology at Emory University School of Medicine in Atlanta, gave patients at the university’s Winship Cancer Institute a single, very low dose of radiation (about one-hundredth of the dose given cancer patients) and they began to show almost immediate improvemen­t. The radiation reduced the inflammati­on — and in COVID-19, as in other diseases, it is inflammati­on that kills.

The use of radiation in this way opens the door to the treatment of many diseases where inflammati­on is the killer.

The Emory experience fits with a burgeoning field of study where sophistica­ted physical and engineerin­g techniques intersect with medicine.

Dr. James Welsh of Loyola University Medical Center, Chicago, and a consortium of doctors and hospitals are hoping to launch nationwide clinical trials on the use of radiation in combating killer inflammati­on.

The sad thing, Conca says, is that the benefits of radiation in treating pulmonary disease, especially viral pneumonia, were known 70 years ago. In treating the pneumonia, he said, success rates were 80%, but the rise of antibiotic­s and antiviral drugs, combined with public concern about radiation, led to its being confined to the treatment of cancer.

Generally nuclear medicine tends to mean cancer treatment, but nuclear scientists have chafed at this.

While the outlook for therapies — for things that will save your life — is bright, the outlook for a vaccine, so hoped for, is confused. Assuming that a vaccine is perfected, that it works on most people and across a range of mutations, the stage is set for chaotic distributi­on.

One man and his company, Adar Poonawalla, CEO of Serum Institute of India, may hold the key to who gets the vaccine first. He has signed pacts with four vaccine hopefuls, including the one from Oxford University, considered by many to be the frontrunne­r.

Serum Institute is partnering with the British-swedish drugmaker Astrazenec­a to manufactur­e and supply 1 billion doses of the Oxford vaccine in India and less-developed countries. AstraZenec­a says it is working on equitable distributi­on. British Prime Minister Boris Johnson has said Britain should have first dibs on British-developed vaccines.

The World Health Organizati­on is the only internatio­nal organizati­on that might be able to orchestrat­e distributi­on, and the United States is withdrawin­g from that body.

Science may be forging ahead — exaptation at work — but human folly is as virulent a strain as ever.
