The monkey supply chain

This piece reveals a hidden vulnerability in the global biotech supply chain that most policymakers overlook: the world's most critical medical countermeasures depend on a single, fragile source of nonhuman primates. Jordan Schneider argues that the geopolitical leverage held by the executive branch and the pharmaceutical industry is not just about chips or rare earth minerals, but about the very animals used to test the vaccines and gene therapies that keep us safe. The evidence presented is stark and unsettling, transforming a biological necessity into a strategic choke point.

The Biological Bottleneck

Schneider immediately dismantles the assumption that the market will simply correct itself. He writes, "If you pay peanuts, you unfortunately no longer get monkeys," a blunt assessment of a market where prices have skyrocketed from a few thousand dollars to as high as $50,000 per animal. The author details how China's decision to halt exports in 2020 caused an immediate collapse in supply, leaving the National Institutes of Health to create a priority process for COVID studies because there literally were not enough subjects to go around. This is not merely a price fluctuation; it is a systemic failure of redundancy.

The monkey supply chain

The framing here is particularly effective because it highlights the biological reality that mice simply cannot replace primates for certain high-stakes research. Schneider notes that for vaccines against dangerous pathogens and complex biologics, "monkeys often remain the model regulators, companies, and funders want to see." This reliance is rooted in the fact that macaques possess immune systems and organ functions far closer to humans than rodents. While the FDA Modernization Act of 2.0 was passed to encourage alternatives like organoids, the author correctly points out that these new methods cannot yet replicate "complete multiorgan interactions and integrated biology." The history of primate use adds weight to this; just as the 1997 FDA Modernization Act began shifting the regulatory landscape, the current crisis shows that statutory changes cannot instantly override biological constraints.

"This business of monkeys is not, in fact, just monkey business."

Critics might argue that the push for alternative testing methods is the only viable long-term solution, rendering the supply chain panic unnecessary. However, Schneider's argument holds up against this by emphasizing the ethical necessity of animal models for diseases like Ebola, where human challenge trials are impossible. The "Animal Rule" allows for drug approval based on animal efficacy when human trials are unethical, meaning the monkey supply is a non-negotiable fail-safe for public health.

The Shift in Geopolitical Leverage

The article traces a fascinating historical arc, explaining how the United States moved from relying on India to becoming dependent on China. Schneider writes, "India said, 'Not my circus,'" referring to the 1978 ban on rhesus exports driven by conservation and religious reverence, which allowed China to fill the void. By the 2010s, China had become the dominant exporter, supplying nearly 60% of the primates imported into the US by 2019. This dependency was not accidental but the result of China's deliberate investment in its own biopharma sector, which saw the value of its leading companies jump from $5 billion to $400 billion in just five years.

The author's insight into the domestic dynamics within China is crucial. He explains that the shortage is not just about export bans but about internal demand, noting that Chinese companies are now accused of "monkey hoarding" to fuel their own drug development. This creates a unique strategic dilemma for the US: the supplier is also a fierce competitor in the same industry. Schneider points out that major Chinese firms like WuXi Biologics have vertically integrated by acquiring breeding facilities, effectively controlling the supply chain from birth to testing. This mirrors the dynamics of other critical supply chains, yet the biological nature of the asset makes it far harder to replicate quickly.

The Flawed Alternatives

When examining potential solutions, Schneider is refreshingly skeptical of the easy fixes. He outlines three options: buying elsewhere, breeding domestically, or acquiring foreign suppliers. The first option, shifting to countries like Cambodia or Vietnam, is fraught with risk. He warns that "a wild-caught monkey falsely labeled as captive-bred can be a disaster for an unwitting company," citing a 2022 Justice Department indictment of Cambodian officials for laundering wild-caught animals. The lack of rigorous health records in these alternative markets means that a vaccine developer could waste millions of dollars on a study that regulators will ultimately reject.

Breeding domestically seems like the cleanest solution, but Schneider dismantles the idea that this can be done overnight. He provides a sobering calculation: even with a large population, the slow reproductive cycle of macaques—gestation of 5.5 months and sexual maturity at 3-4 years—means the US cannot scale up quickly. "Mice, on the other hand, can reproduce exponentially," he contrasts, highlighting the biological lag that makes strategic planning difficult. Furthermore, the US faces stricter animal welfare standards than China, which, while ethically superior, adds complexity and cost to scaling operations. The World Animal Protection Index shows the US rating higher than China, but the author notes this is "not exactly a ringing endorsement," suggesting that even the best US system has room for improvement.

The third option, acquiring foreign suppliers, is exemplified by Charles River Laboratories' attempt to buy a Cambodian breeder. Schneider suggests this might be the "most realistic middle path," allowing US companies to impose their own standards on overseas operations. However, he rightly questions the political and logistical viability of this approach, noting that it still leaves the US dependent on foreign soil and subject to host-country politics.

"Let's stop monkeying around."

The author's call to action is clear: the US needs a comprehensive inventory of its current primate assets and a serious strategy to secure the supply chain. The current approach of hoping for market correction or relying on unproven alternatives is insufficient given the stakes involved in biosecurity.

Bottom Line

Schneider's most compelling argument is that the monkey supply chain is a critical national security issue that has been dangerously underestimated, turning a biological necessity into a geopolitical liability. The piece's greatest strength lies in its refusal to accept the narrative that technology will simply replace animals soon, grounding the analysis in the hard realities of biology and regulatory requirements. The biggest vulnerability in the current strategy is the lack of a coordinated federal response to build domestic capacity or secure reliable foreign partnerships before the next pandemic hits.

Could the future of biotech great-power competition be decided by monkeys?

In 2020, as COVID spread, China stopped exporting research monkeys. For US vaccine developers, infectious-disease researchers, and drug-testing companies, monkeys that once went for only a few thousand dollars suddenly jumped to $20,000 or more. FDA says it now goes as high as $50,000 — if you pay peanuts, you unfortunately no longer get monkeys.

Important projects were scrapped or delayed. The shortage became serious enough that the NIH created a priority process for COVID studies needing nonhuman primates, warning that there weren’t enough monkeys to go around.

China supplied 50.7% of lab monkeys imported into the US in 2006, 69.6% in 2011, 62.8% in 2018, and 48.5% in 2019. Then China’s share collapsed to zero from 2020 onwards. A National Academies report later found that 64% of surveyed NIH-supported researchers had trouble obtaining nonhuman primates.

Monkeys, mostly macaques, still play a big role in biotech. For vaccines against dangerous pathogens, gene therapies, infectious-disease countermeasures, neurotechnology, and complex biologics, monkeys often remain the model regulators, companies, and funders want to see — especially when mice are not similar enough to people and human challenge trials are waiting to get going.

At ChinaTalk, we write about supply chains quite often. This one is different because it is alive.

In one sense, scaling it sounds easy. Put a male and female macaque together, light a few candles, and, with some luck, a new macaque is born. (If only China could do that with two Blackwells.) But achieving monkey sovereignty actually proves to be quite difficult.

This business of monkeys is not, in fact, just monkey business.

Are Monkeys Still Important?.

To be clear, many primate studies are expensive, anachronistic, or less useful than newer human-relevant tools. This is why the FDA Modernization Act 2.0 removed the old statutory assumption that animal studies were required to support certain drug applications. The FDA has since said alternative methods — often called New Approach Methodologies (NAMs) — can help reduce or even replace animal testing when they are scientifically valid.
