The Covid-19 vaccines were designed almost a year ago
You may be surprised to learn that of the trio of long-awaited coronavirus vaccines, the most promising, Moderna’s mRNA-1273, which reported a 94.5 percent efficacy rate on November 16, had been designed by January 13. This was just two days after the genetic sequence had been made public in an act of scientific and humanitarian generosity that resulted in China’s Yong-Zhen Zhang’s being temporarily forced out of his lab. In Massachusetts, the Moderna vaccine design took all of one weekend. It was completed before China had even acknowledged that the disease could be transmitted from human to human, more than a week before the first confirmed coronavirus case in the United States. By the time the first American death was announced a month later, the vaccine had already been manufactured and shipped to the National Institutes of Health for the beginning of its Phase I clinical trial. This is — as the country and the world are rightly celebrating — the fastest timeline of development in the history of vaccines. It also means that for the entire span of the pandemic in this country, which has already killed more than 250,000 Americans, we had the tools we needed to prevent it .
To be clear, I don’t want to suggest that Moderna should have been allowed to roll out its vaccine in February or even in May, when interim results from its Phase I trial demonstrated its basic safety. “That would be like saying we put a man on the moon and then asking the very same day, ‘What about going to Mars?’ ” says Nicholas Christakis, who directs Yale’s Human Nature Lab and whose new book, Apollo’s Arrow, sketches the way COVID-19 may shape our near-term future. Moderna’s speed was “astonishing,” Christakis says, though the design of other vaccines was nearly as fast: BioNTech with Pfizer, Johnson & Johnson, AstraZeneca.
Could things have moved faster from design to deployment? Given the grim prospects for winter, it is tempting to wonder. Perhaps, in the future, we will. But given existing vaccine infrastructure, probably not. Already, as Baylor’s Peter Hotez pointed out to me, “Operation Warp Speed” meant running clinical trials simultaneously rather than sequentially, manufacturing the vaccine at the same time, and authorizing the vaccine under “emergency use” in December based only on preliminary data that doesn’t track the long-term durability of protection or even measure the vaccine’s effect on transmission (only how much it protects against disease). And as Georgetown virologist Angela Rasmussen told me, the name itself may have needlessly risked the trust of Americans already concerned about the safety of this, or any, vaccine. Indeed, it would have been difficult in May to find a single credentialed epidemiologist, vaccine researcher, or public-health official recommending a rapid vaccine rollout — though, it’s worth noting, as early as July the MIT Technology Review reported that a group of 70 scientists in the orbit of Harvard and MIT, including “celebrity geneticist” George Church, were taking a totally DIY nasal-spray vaccine, never even intended to be tested, and developed by a personal genomics entrepreneur named Preston Estep (also the author of a self-help-slash-life-extension book called The Mindspan Diet). China began administering a vaccine to its military in June. Russia approved its version in August. And while most American scientists worried about the speed of those rollouts, and the risks they implied, our approach to the pandemic here raises questions, too, about the strange, complicated, often contradictory ways we approach matters of risk and uncertainty during a pandemic — and how, perhaps, we might think about doing things differently next time. That a vaccine was available for the entire brutal duration may be, to future generations trying to draw lessons from our death and suffering, the most tragic, and ironic, feature of this plague.
