Chicago thinks Zocdoc can help solve its vaccine chaos


During the first week of February, a winter storm blew through Chicago, leaving piles of snow before subzero temperatures set in. Eve Bloomgarden, an endocrinologist at Northwestern Memorial Hospital, got a call from a worried patient who was scheduled to receive a covid-19 vaccine that week. She was preparing to brave the weather—and drive for the first time since the start of the pandemic—because she was concerned that this would be her only chance to get a shot.

“I’m seeing immense frustration and fear that they’re going to be left behind,” Bloomgarden says. 

Chicago, like many parts of the US, has found the distribution of covid-19 vaccines slower than anyone hoped. Just 6% of the city’s 2.7 million residents have been vaccinated so far, and people have said the process is “like the Hunger Games,” requiring them to stay up late to refresh multiple websites in the hope that an open slot will pop up. Making things worse, official sign-up websites are clunky and hard to navigate. 

In early February, the Department of Public Health announced a plan to help ease some of those technical problems: a partnership with Zocdoc, the popular online health-care scheduling company. Zocdoc is acting as a unified portal for multiple providers, so that people can sign up with a single, more user-friendly tool rather than wrestle with several different systems at once. While Chicago is the first city to make this specific agreement with Zocdoc, other health agencies are launching similar partnerships with private startups.

Before the pandemic, Zocdoc acted as a one-stop shop where patients could check out different doctors, compare medical providers, and make appointments. The company’s CEO, Oliver Kharraz, says the years spent bridging a fragmented health-care system unknowingly prepared it for taking on covid-19 vaccination appointments. After the idea was tested with the Mount Sinai Health System in New York, Zocdoc says, Chicago reached out about a partnership—and the system was up and running within a few weeks. Zocdoc connects with 1,400 different scheduling systems: doctors’ workflows remain unchanged, but patients all see the same simple interface no matter which provider they’re using.

“If you’re not plugged into the right system, then how are you going to get access?”

“You don’t have to register 10 times, and you know when the next available shot is for you,” Kharraz says.

Bloomgarden, the doctor at Northwestern Memorial, says the new Zocdoc tool will be a “great addition” to Chicago’s vaccine drive, but that it addresses only one of the issues with the rollout. After all, it’s still a version of the same first-come, first-served approach, which means it’s not solving the most critical problem: vaccines aren’t reaching the people who need them most.

Christina Anderson, deputy commissioner of the Chicago Department of Public Health and chief of operations for covid-19 response, says that while Zocdoc may not be the solution needed to reach and vaccinate elderly Chicagoans, it has the potential to help others who are struggling to get vaccinated, such as those without a primary care provider. 

But Bloomgarden says truly making vaccines accessible will require targeted outreach—much of it offline.

Who you know matters

Local and federal officials in the US seem to be coming to the same conclusion. On February 9, President Joe Biden announced a new program that will provide vaccines directly to community health centers serving 30 million people across the US, two-thirds of whom are at or below the federal poverty line. Federally qualified community health centers receive federal funding to provide care to underserved populations.

Keon L. Gilbert, an associate professor in behavioral science and health education at Saint Louis University, says the approaches to serving particularly vulnerable populations have varied widely from state to state. Some states have moved adults over 65 up the priority list regardless of their other risk factors. Other strategies have come up against obstacles: when Dallas attempted to prioritize vaccinations for eligible people living in hard-hit zip codes—who tend to be people of color—the state threatened to reduce the county’s allotment of doses.

The quest to show that biological sex matters in the immune system

Sabra Klein and Janna Shapiro look at a specimen on a lightbox.


She ultimately found a postdoctoral position in the lab of one of her thesis committee members. And in the years since, as she has established a lab of her own at the university’s Bloomberg School of Public Health, she has painstakingly made the case that sex—defined by biological attributes such as our sex chromosomes, sex hormones, and reproductive tissues—really does influence immune responses. 

Through research in animal models and humans, Klein and others have shown how and why male and female immune systems respond differently to the flu virus, HIV, and certain cancer therapies, and why most women receive greater protection from vaccines but are also more likely to get severe asthma and autoimmune disorders (something that had been known but not attributed specifically to immune differences). “Work from her laboratory has been instrumental in advancing our understanding of vaccine responses and immune function on males and females,” says immunologist Dawn Newcomb of the Vanderbilt University Medical Center in Nashville, Tennessee. (When referring to people in this article, “male” is used as a shorthand for people with XY chromosomes, a penis, and testicles, and who go through a testosterone-dominated puberty, and “female” is used as a shorthand for people with XX chromosomes and a vulva, and who go through an estrogen-dominated puberty.)

Through her research, as well as the unglamorous labor of arranging symposia and meetings, Klein has helped spearhead a shift in immunology, a field that long thought sex differences didn’t matter. Historically, most trials enrolled only males, resulting in uncounted—and likely uncountable—consequences for public health and medicine. The practice has, for example, caused women to be denied a potentially lifesaving HIV therapy and left them likely to endure worse side effects from drugs and vaccines when given the same dose as men.


Men and women don’t experience infectious or autoimmune diseases in the same way. Women are nine times more likely to get lupus than men, and they have been hospitalized at higher rates for some flu strains. Meanwhile, men are significantly more likely to get tuberculosis and to die of covid-19 than women. 

In the 1990s, scientists often attributed such differences to gender rather than sex—to norms, roles, relationships, behaviors, and other sociocultural factors as opposed to biological differences in the immune system.

For example, even though three times as many women have multiple sclerosis as men, immunologists in the 1990s ignored the idea that this difference could have a biological basis, says Rhonda Voskuhl, a neuroimmunologist at the University of California, Los Angeles. “People would say, ‘Oh, the women just complain more—they’re kind of hysterical,’” Voskuhl says. “You had to convince people that it wasn’t just all subjective or environmental, that it was basic biology. So it was an uphill battle.”

Despite a historical practice of “bikini medicine”—the notion that there are no major differences between the sexes outside the parts that fit under a bikini—we now know that whether you’re looking at your metabolism, heart, or immune system, both biological sex differences and sociocultural gender differences exist. And they both play a role in susceptibility to diseases. For instance, men’s greater propensity to tuberculosis—they are almost twice as likely to get it as women—may be attributed partly to differences in their immune responses and partly to the fact that men are more likely to smoke and to work in mining or construction jobs that expose them to toxic substances, which can impair the lungs’ immune defenses. 

How to tease apart the effects of sex and gender? That’s where animal models come in. “Gender is a social construct that we associate with humans, so animals do not have a gender,” says Chyren Hunter, associate director for basic and translational research at the US National Institutes of Health Office of Research on Women’s Health. Seeing the same effect in both animal models and humans is a good starting point for finding out whether an immune response is modulated by sex.

Why can’t tech fix its gender problem?

Not competing in this Olympics, but still contributing to the industry’s success, were the thousands of women who worked in the Valley’s microchip fabrication plants and other manufacturing facilities from the 1960s to the early 1980s. Some were working-class Asian- and Mexican-Americans whose mothers and grandmothers had worked in the orchards and fruit can­neries of the prewar Valley. Others were recent migrants from the East and Midwest, white and often college educated, needing income and interested in technical work. 

With few other technical jobs available to them in the Valley, women would work for less. The preponderance of women on the lines helped keep the region’s factory wages among the lowest in the country. Women continue to dominate high-tech assembly lines, though now most of the factories are located thousands of miles away. In 1970, one early American-owned Mexican production line employed 600 workers, nearly 90% of whom were female. Half a century later the pattern continued: in 2019, women made up 90% of the workforce in one enormous iPhone assembly plant in India. Female production workers make up 80% of the entire tech workforce of Vietnam. 

Venture: “The Boys Club”

Chipmaking’s fiercely competitive and unusually demanding managerial culture proved to be highly influential, filtering down through the millionaires of the first semiconductor generation as they deployed their wealth and managerial experience in other companies. But venture capital was where semiconductor culture cast its longest shadow. 

The Valley’s original venture capitalists were a tight-knit bunch, mostly young men managing older, much richer men’s money. At first there were so few of them that they’d book a table at a San Francisco restaurant, summoning founders to pitch everyone at once. So many opportunities were flowing it didn’t much matter if a deal went to someone else. Charter members like Silicon Valley venture capitalist Reid Dennis called it “The Group.” Other observers, like journalist John W. Wilson, called it “The Boys Club.”

The men who left the Valley’s first silicon chipmaker, Shockley Semiconductor, to start Fairchild Semiconductor in 1957 were called “the Traitorous Eight.”

The venture business was expanding by the early 1970s, even though down markets made it a terrible time to raise money. But the firms founded and led by semiconductor veterans during this period became industry-defining ones. Gene Kleiner left Fairchild Semiconductor to cofound Kleiner Perkins, whose long list of hits included Genentech, Sun Microsystems, AOL, Google, and Amazon. Master intimidator Don Valentine founded Sequoia Capital, making early-stage investments in Atari and Apple, and later in Cisco, Google, Instagram, Airbnb, and many others.

Generations: “Pattern recognition”

Silicon Valley venture capitalists left their mark not only by choosing whom to invest in, but by advising and shaping the business sensibility of those they funded. They were more than bankers. They were mentors, professors, and father figures to young, inexperienced men who often knew a lot about technology and nothing about how to start and grow a business. 

“This model of one generation succeeding and then turning around to offer the next generation of entrepreneurs financial support and managerial expertise,” Silicon Valley historian Leslie Berlin writes, “is one of the most important and under-recognized secrets to Silicon Valley’s ongoing success.” Tech leaders agree with Berlin’s assessment. Apple cofounder Steve Jobs—who learned most of what he knew about business from the men of the semiconductor industry—likened it to passing a baton in a relay race.

Predicting the climate bill’s effects is harder than you might think

Predicting the climate bill’s effects is harder than you might think


Human decision-making can also cause models and reality to misalign. “People don’t necessarily always do what is, on paper, the most economic,” says Robbie Orvis, who leads the energy policy solutions program at Energy Innovation.

This is a common issue for consumer tax credits, like those for electric vehicles or home energy efficiency upgrades. Often people don’t have the information or funds needed to take advantage of tax credits.

Likewise, there are no assurances that credits in the power sectors will have the impact that modelers expect. Finding sites for new power projects and getting permits for them can be challenging, potentially derailing progress. Some of this friction is factored into the models, Orvis says. But there’s still potential for more challenges than modelers expect.

Not enough

Putting too much stock in results from models can be problematic, says James Bushnell, an economist at the University of California, Davis. For one thing, models could overestimate how much behavior change is because of tax credits. Some of the projects that are claiming tax credits would probably have been built anyway, Bushnell says, especially solar and wind installations, which are already becoming more widespread and cheaper to build.

Still, whether or not the bill meets the expectations of the modelers, it’s a step forward in providing climate-friendly incentives, since it replaces solar- and wind-specific credits with broader clean-energy credits that will be more flexible for developers in choosing which technologies to deploy.

Another positive of the legislation is all its long-term investments, whose potential impacts aren’t fully captured in the economic models. The bill includes money for research and development of new technologies like direct air capture and clean hydrogen, which are still unproven but could have major impacts on emissions in the coming decades if they prove to be efficient and practical. 

Whatever the effectiveness of the Inflation Reduction Act, however, it’s clear that more climate action is still needed to meet emissions goals in 2030 and beyond. Indeed, even if the predictions of the modelers are correct, the bill is still not sufficient for the US to meet its stated goals under the Paris agreement of cutting emissions to half of 2005 levels by 2030.

The path ahead for US climate action isn’t as certain as some might wish it were. But with the Inflation Reduction Act, the country has taken a big step. Exactly how big is still an open question.
