We’re Running Out of Money to Track Covid Variants. An Expert Explains Why That Would Be Very Bad.

The United States is at risk of running out of money to fight Covid. Without additional funds from Congress, the White House warned last month, the country will see immediate consequences. Additional, free booster doses for all Americans won’t be possible. Medical providers won’t be reimbursed for treating, testing, or vaccinating uninsured patients. And the federal government won’t have enough cash to make new purchases of treatments like monoclonal antibodies or oral antiviral pills.

Much of the media attention around this possible crisis has focused on these immediate effects—some of which we’re already starting to feel. But perhaps equally concerning, experts say, is how a lack of money may hinder our ability to monitor possible future Covid outbreaks. As I wrote back in December, the United States managed to massively expand its genomic surveillance efforts—that is, our system for tracking new variants—over the course of 2021, in large part due to a boost in federal funds, around the tune of $2 billion. Over the course of the year, the country’s labs went from sequencing a few thousand genomes per week to nearly 100,000 per week by late November. And while Covid cases have since dropped dramatically, the country still sequences tens of thousands of samples per week—critical work that allows scientists to monitor which variants are circulating in the country.

“The only reason we know what’s out there, and potentially try to find what could be next, is through a robust routine genomic surveillance approach.”

But if additional funding disappears, experts say, so may a significant amount of that data, leaving us unprepared to detect and respond to the virus’ evolution. In a March 15 letter to Congress, Biden administration officials said that genomic surveillance efforts may be on the chopping block. “With reduced capability to perform adequate surveillance, the country will be prone to being ‘blindsided’ by future variants,” the letter states. The administration will be forced to “wind down” its surveillance programs, it reads, “leaving us less able to detect the next variant.” Making matters worse, the UK and Denmark, which until now have led the world with their variant-tracking efforts and have served as a sort of early warning signal to the US and other countries, are also making cuts to their programs, prompting concern from health experts.

There are signs that Congress is starting to listen: This week, the Senate unveiled a $10 billion Covid aid billless than half of what the White House initially requested—to continue testing, distributing vaccines, and purchasing therapeutics. But it’s unclear how much of that funding, if passed, will specifically go to genomic surveillance efforts and also how long the Covid cash would last. And the bill still needs to overcome significant political hurdles in the Senate and be approved by the House. (The White House and CDC did not immediately respond to requests for comment about the details of the bill.)

With funding up in the air, I reached out to Joseph Fauver, a genomic epidemiologist at the College of Public Health at the University of Nebraska Medical Center, which is working with the state to track variants, to get a better sense of what the lack of money from Congress may mean for Covid surveillance. It could be “a huge problem,” he emailed back immediately. Below is a lightly edited and condensed version of our phone conversation earlier this week.

Over email, you said that if federal funding for genomic surveillance runs out, that could be a big problem. Can you explain what you meant by that?

Broadly, it’s so short sighted. There are times when you ask yourself, “Have we learned nothing here?” In my mind, the pandemic, obviously, has been so far reaching and been so devastating for so many different reasons. But the things that have just totally altered the trajectory of the pandemic are variants of concern. And the way we find variants of concern is through sequencing and doing routine genomic surveillance.

I feel like the utility of those approaches, it’s unquestionable. It should just be standard practice at this point. The scale of sequencing can vary, sure. You can scale up and scale down, target specific areas if need be. But not having large-scale federal support for genomic surveillance moving forward seems like a very bad idea.

“These tools have led to so much information about why things are the way they are.”

When I give lectures on Covid, I often put a picture of the epi curve in the US, cases over time. And you can put a dotted line when we developed very efficacious vaccines. And the huge increases in cases after much of the country was vaccinated just don’t really make sense—unless you understand variants. And the only reason we know what’s out there, and potentially try to find what could be next, sooner rather than later, is through a robust routine genomic surveillance approach.
