The Feds Are Spending Millions to Help You Survive Nuclear War – WIRED

Last week, as tens of thousands of US and South Korean soldiers gathered at a base in Iwakuni, Japan for an annual joint military exercise, North Korea fired four ballistic missiles from Pyongyang into the sea off Japans northwest coast. In a world where the US is headed by a Twigger-happy political neophyte and the risk of a Cold War reboot looms larger with each Wikileaks disclosure, this demonstration wasnt just an empty display of dictatorial propaganda. It was a reminder that the nuclear threat is still alive and well.
But even if youve taken a decades-long break from stocking your fallout shelter, the federal government hasnt. Over the last ten years the US has poured millions of dollars into technologies and treatments it hopes to never have to use, but could, in the event of a nuclear catastrophe. From assays that measure radiation exposure to cell therapies that restore dwindling blood cells to liquid spray skin grafts, government officials are now far better equipped to deal with diagnosing and treating people if the unthinkable were to happen. And the next generation of treatments are being funded right now.
In 2006, the Department of Health and Human Services established the Public Health Emergency Medical Countermeasures Enterprise to coordinate federal solutions to large-scale public health threats, including the nuclear one. Pretty much every agency you can think of is involvedCDC, NIH, FDA, DoD, DHS, USDA, VA, and OEM, among others. But in terms of nuclear countermeasures, three programs nested within HHS do the bulk of the heavy lifting.
The NIHs National Institute of Allergy and Infectious Disease is the first stop; it runs clinical and preclinical trials for promising technologies. Then theres the Biomedical Advanced Research and Development AuthorityBardawhich is basically a taxpayer-backed investment firm that develops these potential drugs, vaccines, treatments, and supplies and ushers them through FDA approval. Finally theres Project BioShield, which contracts with companies when their products are almost ready, ensuring a national market. To date, the project has acquired 12 products related to a nuclear blast or reactor meltdown, some FDA-approved, some still in late stage development, but all destined for the Strategic National Stockpile, the CDC-managed backup supply of drugs and medical supplies for use in a public health emergency. And each class of products addresses a different part of the threat.
The first is diagnosis. When a person is exposed to high levels of radiation, unpaired electrons careen around their cellular machinery, breaking DNA and causing damage to every organ, including the bone marrow. This means you cant generate new red blood cells, white blood cells, and platelets, so you cant fight off infections or coagulate your blood. People usually dont start feeling the effects of acute radiation syndrome for 24 to 48 hours, but damage to their cells DNA starts almost immediately. Which is why you need a reliable diagnostic device; following a nuclear event, people who feel well might actually be in danger, and people who werent exposed will want treatment just to be safe.
So Project BioShield acquired two diagnostic devices, known as biodosimeters, to tell the difference. One works by measuring gene expression, the other by visually analyzing cell nuclei. In the event of a nuclear event, the countermeasures weve procured will be precious resources, says Joe Larsen, acting director of Bardas division of chemical, biological, radiological, and nuclear medical countermeasures. Were going to end up with a lot of worried well demanding treatment, and we can only afford to treat people that need it.
That treatment, at least right now, consists of injections of immune-boosting cytokines, developed for cancer patients to restore depleted white blood cells lost during radiation treatments or chemotherapy. Project BioShield has acquired three such cytokine treatmentsbut, Larsen notes, they wont work for about 20 percent of people. For them, the only option will be bone marrow or cord blood transplants, which come with the extra obstacle of having to be matched with a donor. So Barda and Project BioShield are now looking for cellular therapies that dont require any donor matching to their portfolioa universal treatment. That could shore up gaps in our initial capability to treat radiation. And theyve got at a few promising options coming down the pipeline.
Barda recently signed a $188 million contract to developa stem cell therapy produced by California-based Cellerant Therapeutics, which restores white blood cells in leukemia patients whove had theirs taken outby chemotherapy. The cells are cryopreserved and shelf-stable, important features for a stockpile item. But the treatment is focused on white blood cells, and radiation exposure doesnt limit itself to the immune systems front-line fighters.
To that end, NIAID is funding clinical trials for a placenta-derived stem cell treatment developed by an Israeli company, Pluristem, that has shown the ability to restore all three blood cell linesred and white blood cells, as well as plateletsin animal models. Like Cellerants, the treatment comes cryogenically frozen along with a thawing device to deploy it easily in the field. The cells stay viable on liquid nitrogen inside their canisters, so you dont have to worry about losing them if the power goes out. From their injection site, the placental stem cells sense stress signals in bone marrow tissues, and send more than 20 signaling molecules to repair and restore their functions. The company isnt testing efficacy in humans, for obvious reasons. But Pluristem says their animal studies showed close to 100 percent survival rates with the treatment, compared to 30 percent without.
Arik Eisenkraft, who began working on an ARS application for Pluristems technology following the Fukushima disaster, isnt surprised that a potential solution to nuclear radiation would come out of a place like Israel. We live in a world of imminent threats, not theoretical ones, he said. Even though we dont have the same budgets and the same scope of institutes, what we do have is a real sense of urgency.
Neither Barda nor Pluristem could confirm whether or not a contract is somewhere in their future. But the agency did say it was looking at all the options. And with Bardas budget cut by $160 million last year and an uncertain future for disaster preparedness funds in a Trump administration, theres no time like the present for some urgency of their own.
