![]() Sequence Review Code Released PubliclyIn mid-December, 51,000 covid genomes from the US had already been decoded and posted in public repositories. And it’s been done at an unprecedented scale. Use the Command - K keyboard shortcut to crop the image.Scientists have been sequencing the genomes of covid samples since the first identified case in Wuhan the first mRNA vaccines were built using genetic code released publicly by Chinese scientists in January. Some frustration was certainly driven by inaccurate messaging: on December 22, for instance, the New York Times reported that fewer than 40 covid genomes had been sequenced in the US since December 1. Related StoryEven in November and December, as both the UK and South Africa announced more transmissible strains and Denmark said it would kill 15 million mink to contain a mutation, many scientists and public health organizations argued that the virus was unlikely to escape vaccine-induced immunity.Still, as headlines warned about “ mutant coronavirus” spreading “ out of control,” politicians and the public demanded to know whether there were “variants of concern” in their own backyards.“Given the small fraction of US infections that have been sequenced, the variant could already be in the United States without having been detected,” the CDC responded, in a statement published online.“America is flying blind” quickly became a refrain, not only for scientists seeking support for their work, but for critics of the US response looking for a solvable problem. That’s mostly because until recently it was considered an academic pursuit, tracking changes in a virus widely believed to evolve slowly and steadily. The Sequence dialog organizes the development of a sequence through the following dialog.The vast majority of covid sequencing in America has been conducted at academic centers. But despite the increase in genomic sequencing, some public health experts and scientists are now wondering what’s being done with all this information—and how achievable the field’s goals are.On its site describing genomic surveillance, the CDC says that sequencing can track whether variants have learned to evade vaccines or treatments. It has widespread infections, a genetically diverse population, and the largest number of vaccinated individuals in the world. In the last week of March, when there were 450,000 reported new cases, US labs—including academic labs funded through other programs—submitted 16,143 anonymized sequences to GISAID, a global repository of biological data, and 6,811 to the National Center for Biotechnology Information, or NCBI.(That period saw one of the lowest case rates in six months, however to sequence 5% during the January peak, US labs would have needed to spend well over a million dollars a day sequencing five times the number of samples.)America should be an excellent place to study the genetic evolution of covid. The US quickly met that goal, mostly by paying private testing labs to sequence a small number of positive samples.The CDC and the WHO set a goal of sequencing 5% of positive cases to track variant spread—a number based on a pre-print study from the dominant manufacturer of covid sequencers, Illumina.The US quickly met that goal, mostly by paying private testing labs to sequence a small number of positive samples. Then the relief bill passed in March dedicated an eye-popping $1.75 billion to support nationwide public health programs sequencing “diseases or infections, including covid–19.”The CDC and the WHO set a goal of sequencing 5% of positive covid cases to track variant spread. Qi macros for excel 2010 free downloadBut sequences can’t tell you those things unless connected with information about the people they came from. We need to do more science to understand if it’s doing something we’re actually worried about.”Knowing when variants learn to evade immune systems can tell scientists whether they need to change vaccine formulas. Often, though, such arguments conflate two things: sampling positive tests that have been anonymized, and using targeted analysis to understand specific, identifiable cases.The CDC’s page on surveillance sequencing of covid variants, for example, claims that “routine analysis of genetic sequence data” can help detect variants with the “ability to evade natural or vaccine-induced immunity” and “cause either milder or more severe disease in people.”"Just because you’re seeing a variant more often, does that mean it’s actually more transmissible? Maybe. If one strain increases faster than others, researchers can home in on it for further investigation.“Our surveillance is imperfect, but we are able to see when and where we’re getting transmission across a region, and identify broad-scale patterns of change,” says Duncan MacCannell, chief science officer of the Office of Advanced Molecular Detection, or OAMD, the CDC office responsible for expanding national sequencing efforts.When asked why surveillance sequencing is so important, it’s common for authorities to respond that it can help track how a strain behaves in the real world. “I would be very disappointed if all this money just went to getting a whole bunch of covid sequences, and no thought went toward building something that lasts.” What surveillance sequencing can’t doThere’s no question sequencing has been revolutionary for public health, not least because the mRNA vaccines were developed using sequences made public just a month after a man turned up at a Wuhan hospital with a strange illness.Surveillance sequencing, which identifies the genetic code of a portion of positive tests and looks for changes over time, can help researchers track the virus’s evolution. But in response to news that more transmissible variants are well established in America, states have been relaxing mask mandates and reopening indoor dining.We spoke to a number of sequencing experts with firsthand experience during the pandemic and heard the same from many of them: turning surveillance data into useful knowledge faces enormous legal, political, and infrastructural barriers in the US, some of them insurmountable.Unless scientists and policymakers ask why they want covid sequences, and how best to put that data to use, genomic surveillance will yield diminishing returns—and much of its potential will likely be wasted.“It’s insanely difficult to do this well in the United States,” says Lane Warmbrod, senior analyst at the Johns Hopkins Center for Health Security. Create disk image for macThose test tube studies are the source of most recent headlines about variants getting around protection conferred by vaccines. If one branch of the virus grows quicker than others, or one mutation keeps showing up in different families, it can be flagged for attention.At the same time, OAMD is collecting raw samples from public health labs around the country to study in the lab, growing the viral samples in dishes and pitting them against therapeutics and patients’ antibodies. It’s also tracking when and where different branches of covid-19’s family tree are spreading, and which genetic changes crop up repeatedly. The project is primarily looking for “variants of concern,” strains already suspected to cause worse outcomes or spread faster. “We need to do more science to understand if it’s doing something we’re actually worried about.”That LabCorp contract is part of OAMD’s primary sequencing program, which pays large testing labs across the country to sequence thousands of positive covid tests. Whether or not the owners of that data are interested in turning the information over to the government, collecting it would typically require getting consent from each individual, a very laborious undertaking. In the US, most patient records—test results, immunization information, hospital records—are scattered across many unconnected databases. Taking the 10,000-foot viewAccording to MacCannell, the OAMD has no intention of contextualizing its de-identified data with clinical information.“Those contracts are set up to give us the 10,000-foot view,” says MacCannell.Even if it wanted to combine surveillance sequences with patient information in its analyses, the agency would be fighting a massive uphill battle.
