The Road from SARS-CoV-2 to RFK Jr
How COVID broke our social immune system
The erosion of trust, coordination, and scientific authority in science and public health that grew during the pandemic now shapes federal science policy. It began when viral ambiguity collided with attention-driven information systems.
Acquired Social Immune Deficiency Syndrome
From the perspective of a virus, humans are a problem to be solved.
Success requires entering a host, infecting a cell, replicating efficiently, and finding a path to the next host — all while overcoming whatever obstacles that host places in its way. SARS-CoV-2 solved those problems extraordinarily well. In doing so, it killed millions of people worldwide and exposed profound vulnerabilities in the public health and scientific systems designed to protect us.
A virus infecting any animal faces a biological immune system. Humans pose a unique challenge. Success as a pathogen requires defeating a much more challenging foe—our social immune system, which consists of:
An extensive system for scientific inquiry: The astonishing capabilities of this system were rarely more apparent than during the early days of COVID when it deciphered a virus never seen before, quantified its effects, and developed effective vaccines and treatments in a matter of months.
Public health institutions These systems also proved remarkably effective in the early days of COVID, saving millions of lives worldwide.
Communication systems Collective response is only as effective as our ability to connect expert communities and to share public information systems. Our ability to communicate has never been greater.
Our capacity to understand, communicate about, and act collectively to stop pathogens is powerful enough to take one of the deadliest pathogens ever to infect humans and relegate it to a freezer.
No other species coordinates national vaccination campaigns. No other species communicates genomic sequencing in real time. No other species even knows viruses exist.
But, like all systems, our social immune system has vulnerabilities. SARS-CoV-2 revealed them all.
The pandemic demonstrated that this system can fail catastrophically. That failure reflects the interaction of the virus, the pandemic it caused, and the modern information ecosystem.
An HIV infection’s most devastating effects arise from the damage it inflicts on the biological immune system. SARS-CoV-2 may ultimately be remembered for the damage it did to our social immune system. For the purposes of discussion, let’s call it Acquired Social Immune Deficiency Syndrome, or ASIDS.
This series of posts will provide examples that demonstrate the emergence ASIDS during the pandemic, and then explore its impact on current public policy and science. But first, let’s consider the players in this drama—the virus, the information landscape, and the feedback loop that created and amplified misinformation.
Viral Confusion
SARS-CoV-2 arrived with a constellation of traits that made it uniquely difficult to control. To understand why, consider the story of its namesake, another virus that made the leap from bats to humans, SARS-CoV-1.
The name, Severe Acute Respiratory Syndrome (SARS) was coined for a mysterious infection that appeared in China in 2002. The virus was notable for making almost everyone it infected very sick, very quickly. It rarely spread from someone without symptoms. It killed ten percent of those infected. And it did not discriminate by age.
SARS-CoV-2, by contrast:
Was transmissible 1-2 days before symptoms appeared.
People could spread the virus before they knew they were infected. This undermined traditional containment strategies and made individual risk perception unreliable.Could infect with mild symptoms or no symptoms at all,
This created confusion about the severity of disease and the necessity of interventions.Posed a threat that varied wildly with age.
The elderly and the young experienced two very different pandemics. For some, it threatened their lives. For others it was the interventions that threatened their lifestyle.Had a middling infection fatality rate
No one needed to be convinced to take precautions against SARS, which killed one in ten. Influenza, which typically kills on in a thousand, does not inspire fear, or even precautions. COVID-19, by killing one in a hundred, fell in a dangerous middle ground that, ironically, made it far more dangerous than SARS, which killed less than 800 people world wide.
All these factors combined to make SARS-CoV-2, above all else, a generator of confusion. It was inconsistent and unpredictable in every way. And, to make matters worse, it was a shape shifter. As an RNA virus, it mutated rapidly, reinventing itself throughout the pandemic.
Which leads to one other critical difference between SARS-CoV-1 and SARS-CoV-2.
When it arrived.
The Changing Information Landscape
Between the SARS outbreak of 2002 and the COVID pandemic of 2020, the shift in the information ecosystem was nothing short of revolutionary.
In 2002:
Urgent epidemic information spread through specialized networks.
The rapid spread of scientific information occurred primarily through list serves among expert communities and public health practitioners such as ProMed (Program for Monitoring Emerging Diseases) and EIN (Emerging Infections Networks).Public Health Agencies made management decisions in consultation with the expert Communities.
The World Health Organization, the US Centers for Disease Control, and national CDC equivalents provided regular updates to the broader medical and public health communities and coordinated activities across levels of government.Scientific publishing provided thoroughly vetted commentary and peer reviewed research after the fact.
Preprint services did not exist for the biological and medical sciences. Rapid release meant within a month. Peer review could take a year or more and appeared behind steep pay walls.Science journalists followed and reported on these sources through conventional media.
This provided a common narrative for the public, which generally had a high degree of trust in the medical, scientific, and public health communities.Social media did not exist.
Facebook launched in 2004, Twitter in 2006.
By 2020:
All the above sources existed, but rapid communication was dominated by other sources.
Scientific Journals struggled to keep up. In an unprecedented move, they dropped paywalls for COVID, but even fast-tracked papers took a month or more to appear and the rapid vetting resulted in a dramatic increase in retractions.
Preprint servers had arrived for the biomedical sciences. biorXiv had existed since 2013, medrXiv launched 6 months before COVID. They became the single most important tool for rapid dissemination of research.
Social media dominated rapid spread of information. This was not just true for the general public. As documented by Nature as early as 2014, Twitter had become the preferred tool for rapid research discovery and discussion in the scientific community. However, public interest in COVID meant that conversations were no longer limited to the expert community. Non-experts suddenly had an equal, and ultimately louder, voice in online discussions.
Political polarization defined sides in scientific debates. Political parties fed on division and sought to amplify sides in scientific debates, demanding allegiance to one perspective on key issues.
The information ecosystem had become algorithmic, fast, and attention-driven. Controversy captured eyeballs and amplified dissident voices.
SARS-CoV-2 entered not only a biological host, but a networked one.
The Positive Feedback Loop
A biologically ambiguous virus met an amplification-driven information system. SARS-CoV-2 provided mixed signals about the nature of the threat and the effectiveness of our response.
Ambiguity created controversy. Controversy captured eyeballs. Engagement, amplified by a divisive political landscape, fragmented public opinion and undermined public support for a coherent public health response. That impaired response increased transmission. Increased transmission both fed the narrative that interventions were ineffective and gave the virus expanded opportunities to mutate.
The pandemic was not driven solely by viral replication. It was driven by a feedback loop between viral traits and informational dynamics. Viral traits that amplified ambiguity had a selective advantage.
This loop weakened coordinated response from our social immune system.
In an information ecosystem that rewards controversy, fragmentation is not an accident — it is an outcome. When beliefs fragment, any response — even an optimal one — generates a constituency convinced it is wrong. Trust does not simply erode; it redistributes to competing narratives.
Over time, that process weakened the institutions that constitute our social immune system.
Damage to that system is having and will have consequences far beyond our response to COVID.
In the next installment, I will revisit pivotal moments of the pandemic and trace how ambiguity, amplification, and polarization combined to erode trust and impair response. The damage was not abstract. It reshaped public health in ways we are only beginning to confront.
Bob, thank you. As a long hauler it’s valuable to me to have help organizing my thoughts and your piece does that for me. As an older adult my principal concern is that we process what happened - as another pandemic is inevitable.
