The Unbelievable Speed of the COVID-19 Response: A Closer Look at the Miracle of Modern Medicine
COVID-19 Outbreak at 5 Years: Could Budget Reductions Impede Future Emergency Readiness?
Feels like the COVID-19 pandemic hit us out of nowhere, right? Officially declared by the World Health Organization on March 11, 2020, it didn't take long for the world to shut down. Death tolls rose, hospitals brimmed with patients, and our lives drastically changed overnight. It seemed as if medical advancements were happening just as quickly. An antiviral for reducing disease severity and death became available seven months after the pandemic kicked off, followed by mRNA vaccines two months later. But let's not be fooled – the rapid development of these life-saving remedies didn't happen overnight. Rather, it was a testament to years of basic research, much of it federally funded.
Spoiler alert: this wasn't a 2020 story.
Basic Research and the COVID-19 Response: The Case of Remdesivir
Enter Dr. Mark Denison, the genius behind the division of pediatric infectious diseases at Vanderbilt University Medical Center. He may not have set out to save the world, but he sure did, at least when it comes to COVID-19. You might know him for his work on remdesivir, an antiviral compound that came to our rescue during the pandemic, but even he didn't start out with that goal in mind.
Denison has been studying coronaviruses for four decades. In a recent chat, he reminisced about his work on remdesivir, which began as a quest to understand the role of the coronavirus ExoN protein – a "weird" enzyme that acts as a proofreading enzyme, helping the virus fix mistakes during replication. Naturally curious, Denison set out to explore how this enzyme contributed to coronavirus replication. Ultimately, his team discovered a compound that inhibited the enzyme, leading to the inhibition of viral replication in cell culture, and success in animal and human trials.
In retrospect, the approach seems straightforward, but it wasn't his career objective to find an antiviral. So much for saving the world, right?
A Nobel-worthy Story: The Development of COVID-19 mRNA Vaccines
Remdesivir wasn't the only COVID-19 game-changer. Drs. Katalin Karikó and Drew Weissman received the 2023 Nobel Prize in Physiology or Medicine for their pioneering work that paved the way for mRNA vaccines. We've seen the effects of their work – millions of lives saved, society opening up, and a return to (some semblance of) normalcy. But the award wasn't for the development of the vaccines themselves; rather, it was for their groundbreaking work on our immunological response to mRNA and a peculiar RNA component called pseudouridine.
Their award-winning work took place more than 15 years ago, way before the pandemic even began. They didn't start with the intention to change history; they were simply intrigued by how our immune systems react to mRNA and pseudouridine. And the amazing outcomes didn't just happen overnight; numerous researchers had laid the groundwork beforehand, tackling topics like RNA synthesis and delivery into cells.
The Iterative Nature of Science
If you're wondering, "What's the caper here?" – don't worry, you're not alone. The thing about science is, it's a crazy, iterative process, with seemingly unrelated research sometimes coming together in the most unexpected ways. Finding antivirals wasn't on Dr. Denison's career bucket list, and the mRNA vaccine development team probably didn't have the pandemic in mind when they started out. But, lucky for us, their curiosity led to some incredible discoveries that ended up saving millions of lives.
Most of the research that led to the development of remdesivir, molnupiravir, the mRNA vaccines, and other COVID-19 treatments was supported by the National Institutes of Health (NIH). With a hefty budget of nearly $48 billion and resources to support over 300,000 researchers at more than 2,500 institutions, the NIH is a powerhouse of scientific progress. The remarkable outcomes of this funding are evident – over 170 NIH-employed or -funded scientists are Nobel Prize recipients, spurring countless other researchers to make small but impactful advancements, often fueled by curiosity alone.
The Looming Threat of Funding Cuts
But here's the catch – recent proposals to cut funding to the NIH could derail this basic research. Proposed cuts could stall the iterative process that science is, making it difficult for universities and medical schools to continue exploring those important biological systems that fuel human understanding, if not for immediate rewards, then for the sheer love of discovery. It could mean that, next time, we won't be as fortunate as we were during the COVID-19 pandemic. So, let's keep the funding flowing, shall we? Our future (warp-speed) responses depend on it.
In February, the Trump administration proposed a drastic cut to the indirect costs associated with NIH grants – overhead costs that help institutions pay for critical services like animal care facilities and hazardous waste disposal. The loss of these funds could be devastating for the basic research happening at universities and medical schools around the country.
Cuts to the Centers for Disease Control and Prevention could undermine vital public health programs, like a flu vaccine education program that has already been halted due to an expanding avian flu outbreak. The disruption of surveillance programs could impede our efforts to identify other outbreaks, leaving us vulnerable to threats we could otherwise avoid.
So, let's not tempt fate. Support the funding that drives basic research and empowers scientists like Drs. Denison, Karikó, and Weissman to continue making groundbreaking discoveries that will keep us safe in the face of future pandemics.
