Last month, Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, spoke at a biotechnology conference, highlighting how unknown coronavirus is still. “I think HIV was a confusing disease,” he said. “It’s undeniable compared to what’s happening with COVID-19.” For anyone who knows the history of AIDS studies, Fauci has spent much of his career reading the disease, it was daunting to hear it. In 1984, President Reagan’s Secretary of Health and Human Services, Margaret Heckler, said, “We hope to have a vaccine in a position to be tested in about two years.” Nearly 4 decades later, there is still no vaccine. While Heckler’s words now seem to be an illusion, the Trump administration has troubled scientists and doctors with what might turn out to be a similar over-the-waiting over- In May, he unveiled a plan to administer “hundreds of millions of doses” of a COVID-19 vaccine until the end of this year. The plan call – Operation Warp Speed – is finished to increase hope. But in science, true hope has a vision for the future and focuses on the possible obstacles and setbacks that exist on the way to the desired results.

In the face of a crisis as pressing as COVID-19, speed is desirable and global mobilization to defeat the virus has been inspiring. But what Fauci said illustrates why it is a grave mistake to privilege speed over rigor. It is just a disease that we are just beginning to understand: since the beginning of the epidemic, it has become transparent that its effects are, like those of AIDS, unexpectedly varied and complex. It is still considered a respiratory disease (in fact, it can cause devastating damage to the lungs), in fact, as Fauci has pointed out, it is able to spread throughout the body. There are cases where it causes kidney failure, stroke or the so-called cytokine storm, an overreaction of the body’s immune formula that can cause multi-organ failure. In children, the infection can cause multiformulaic inflammatory syndrome, a disease that can damage the center and other important organs. COVID-19 has an unexpected spectrum of severity, from the absence of symptoms to death, which is based on a number of misunderstood factors. Fauci also pointed to another unknown: if some survivors, especially those with the most severe symptoms, would end up suffering debilitating effects for life. Currently, we don’t even know how to evaluate protective immunity if we had a vaccine in hand: if coverage would be broad for all age teams and would come with other healthy people, as well as those whose clinical conditions, such as diabetes, focus on disease and obesity, they predispose them to COVID-19. Even more worrying, for those who believe that a vaccine may also end the pandemic, such as turning off a switch, a number of recent studies recommend that others with the disease may not emerge with strong and lasting immunity. If this is the case, it is conceivable that the initial coverage presented through an effective vaccine is minimized in the same way and that other people may inflate again.
It is understandable that we are all desperate for quick solutions, with the number of infections and deaths shooting. Since January, some 1,200 clinical studies have been developed, but many are too small to have a smart chance of generating transparent effects. Researchers published their documents online before being peer-reviewed. In May, the Modern Biotech Corporation launched the first effects of an early trial of its vaccine in a press release. Moderna’s vaccine ruled out news of the studies last week, after more complete effects of the trial were published in the New England Journal of Medicine. This painting is still an initial achievement, as there were only fifteen healthy volunteers in each of the 3-dose vaccine teams and, in moderate and high-dose equipment, almost all volunteers had side effects. A deputy editorial through Penny Heaton of the Gates Foundation warned that we may not know literally about protecting The Modern Vaccine until thousands more people get it, or if the immune reaction reported in volunteers is in fact protective of the virus. There are apparent dangers in testing in humans. Like Kenneth Frazier, the C.E.O. Merck,” he noted last week, there have been cases, in the past, where control vaccines “not only did not provide protection, but actually helped the virus invade the cell, because it was incomplete in terms of immunogenic properties.” Promises to hold a vaccine until the end of the year,” he said, “have greatly harmed the public.”
Producing a vaccine capable of granting immunity to equipment of different ages with other degrees of vulnerability is a huge task, especially since COVID-19 is an entirely new disease in humans and therefore opposes us not having herbal immunity. (Even a vaccine as relatively undeniable as the annual flu vaccine reduces the threat of influenza disease to only 40 to 60% of recipients). All of this means that a first vaccine, a welcome tool in combating COVID-19, may well prove to be of limited use. The lesson learned from AIDS is the price of building a protective clinical infrastructure beyond a vaccine, which requires legions of scientists working consciously and collaboratively to perceive the many tactics in which a virus causes disease.
In early June, I visited the National Laboratories for Emerging Infectious Diseases (NEIDL) to interview researchers working with COVID-19. Part of Boston University, NEIDL (pronounced “needle”) is one of two U.S.-affiliated educational establishments. With laboratories qualified to treat the deadliest known human pathogens, such as Ebola and Marburg viruses and yellow fever. NEIDL’s origins date back to the post-9/11 period, when Fauci warned that the country needed a major formula to protect itself from imaginable bioterrorist attacks, and the past government allocated billions of dollars to prepare for such an event. NEIDL gained its investment in 2003, however, it takes years to prepare a facility to treat these pathogens: the construction itself was completed in 2008; obtaining mandatory environmental approvals from local government and representatives of networked paintings took nearly a decade. It was not until 2017 that NEIDL was fully approved to adopt all the paintings for which it was created.
The facility, located in the B.U. Medical Campus in the South District of Boston is a modern seven-story glass and concrete design. Barriers surround the site a hundred and fifty feet away from construction; They are supplied with motion detection sensors and are tough enough to cause a fifteen thousand pound truck to drive fifty miles according to the hour. Inside, there are a dozen participating laboratories for harmful microbes, involving specialized microscopic devices and robotic devices, and safe environmental services designed for pathogenic vectors, such as mosquitoes and ticks, and animals, that researchers use to design human diseases. NEIDL’s Level Four biological safety facility, the building component that is authorized to treat maximum harmful microbes, is built as a construction in the most giant construction. This interlaced design has twelve-inch thick concrete walls covered with several layers of epoxy resin. While the NEIDL itself is built on stilts entering the mother rock, the four floors B.S.L. are flexible and can move to another frequency from the main design in the event of an earthquake. Researchers paint in sealed suits, similar to those of astronauts, with a giant transparent bubble over the head, fed with filtered air through a pipe connected to the ceiling. In the event of a spill, the area is regularly decontaminated with chlorine dioxide and a low air voltage mostly in the lab ensures that air enters rather than leaves, so that viruses cannot escape into the air.
NEIDL has been running on live coronavirus patterns since March, when it won a pattern stemming from the first case diagnosed in the United States: a 35-year-old man in Washington state who had recently returned from Wuhan. But their staff had been making plans to investigate the virus since January, when initial reports of its immediate spread convinced them that it would proliferate internationally and cause serious outbreaks in the United States, and without delay began drafting protocols for the use of the virus. and the submission of programs for approval. In March, BU institutions, which added NEIDL, earned $1.9 million in investment from the Massachusetts Consortium on pathogen preparedness as a component of a $15 million grant, coordinated through the Dean of Harvard Medical School and funded through a Chinese Investment Fund, for researchers working in the Boston and Guangzhou Area.
In the United States, the top B.S.L.-4 laboratories are located in government or army facilities, however, NEIDL, despite its origin under a federal initiative, operates on an open educational model. “We painted with absolute transparency,” its director, Ronald Corley, told me. “We will have to have the trust of the public, so that everything we do is freely known and communicated.” Over the past two years, Corley, a microbiologist in her 60s, has recruited fourteen scientists to enroll in the center, looking for researchers with a wide variety of experience. NEIDL and its affiliates have experts in the fundamental biology of the deadliest pathogens, animal models that can be used to mimic advances in human diseases, and effective remedies and possible vaccines. Corley believes in giving them the freedom to pursue their intuitions without being micromanaged. From the outset, he analyzed the diversity of the center’s studies on COVID-19 with the presumption that it would be, as recent evidence has shown, an evolving goal, and that progress would likely come to the fullest of an organization of approaches than from a single advance.
Since Donald Trump took office, his administration has sought to systematically dismantle key elements of federal planning for a pandemic. In 2018, it largely disbanded the National Security Council’s pandemic preparedness unit, which was shaped by the Obama administration, after ignoring the Council’s pandemic manual. He got rid of Rick Bright from his position as head of social facilities and fitness at the rate of vaccine progression after filing a three-hundred-page complaint about management’s reaction to coronavirus. More recently, the White House ordered the National Institutes of Health to reduce investments for federal grants to EcoHealth Alliance, a New York-based organization that studies the global spread of viruses from animals to humans, and has collaborated on coronavirus studies with informed researchers. china.
But some facets of the country’s pandemic plans have survived, in a giant component because they have been designed as sustainable clinical research focus on maximum harmful biological threats. NEIDL was designed to be policy-independent and able to respond consistently to a national emergency. Its technique is the opposite of the language of the “distortion speed” popularized to the public.
“There are a lot of smart paintings all over the world,” Corley said. “There’s also a lot of rubbish, because other people rush.” The challenge is not just negligence; Laboratories are synthetic environments throughout nature, and even the most thorough paints can lead to obvious advances that turn out to be artifacts of the experimental procedure. When a virus infects human cells that grow in the lab, it can mutate slightly. It is possible to spend years preparing a treatment for a modified form of a pathogen only to realize that this treatment does not provide any advantage to patients. Corley and his team sequenced the genes from their virus samples several times while painting to make sure the pathogen does not take a form that no longer corresponds to the one originally recovered from the Seattle patient, a time-consuming procedure. necessary, precautionary.
When Corley toured the facility and took me to his researchers, they gave me a concept of NEIDL’s institutional preference for attention to speed. Anthony Griffiths, a virologist and Ebola expert who focuses on animal modeling, has obviously pointed out the price of planned science. “I was informed by Ebola classes. I sense the speed,” he told me. “But if you do science in a hurry, you threaten to enter the garden.” Griffiths hopes to use observations of disease progression in animal hosts (genetically manipulated mice, gilded Syrian hamsters and rhesus monkeys) to be more informed about their mechanisms and verify imaginable treatments. This can also help determine the amount of viruses you want to provide to cause infection and inoculation pathways imaginable, to detect the dynamics of human immunity against coronavirus. “I’d love to be the first, but we probably probably won’t be,” he told me. “But we need to put ourselves in the most productive position to make the kind of paints that can help perceive the functionality of the vaccine and what its possible limitations would be.”
Griffiths largely paints with Nahid Bhadelia, an infectious disease doctor at Boston Medical Center, an expert on emerging pathogens. In 2014, the Ebola outbreak in West Africa was part of a W.H.O. team that treated patients and trained local caregivers. Part of its role is to draw neIDL scientists’ attention to the evolving and unexplained clinical discoveries of COVID-19, such as those known through Fauci, for laboratory study. For example, he looked at patients who tested positive for SARS-CoV-2, the virus that causes COVID-19, and then tested negative several times and then tested positive again. “Have they been reinfected or has their immunity decreased?” She. “Or were they just spreading the virus from the initial infection?” Together with NEIDL scientists, he is running to take a chronological series of virus samples from these patients. Genetic research can show whether a patient was using the same pathogen at other times or if the virus mutated in a way that exceeded the person’s immune response. These paintings will ultimately facilitate the evaluation of the most likely activity of possible vaccines. Bhadelia also noted that some patients who “were not very sick, meaning they were not in the IU, however, seem to have residual cognitive problems. These persistent effects can be modeled prospectively in animal studies in NEIDL.
Rob Davey, an Australian microbiologist with an ironic sense of humor and a way of speaking hyperkinetics, is an expert at finding new remedies for pathogens. In 2018, while running with Corporate Biotechnology Regenerate, Davey helped identify a type of antibody that effectively treated Ebola in animal subjects by binding to viral proteins and blocking the microbe from entering cells. These antibodies have eventually become remedies for inflamed patients. Since you started running with COVID-19, you’ve been in favor of agents that can disrupt disease progression. Lately he is examining about seven thousand chemicals he received from the Broad Institute (the Harvard-M.I.T. joint venture that specializes in gathering giant libraries of chemical compounds), as well as another thirty-two hundred more provided through the U.B. Some of these compounds are medications that are already used for diseases such as diabetes, high blood pressure and migraine. If Davey’s screening procedure indicates that one of them has a chance of receiving COVID-19 treatment, patients’ tests may be maintained quickly as they already have F.D.A. Approval.
To detect so many compounds, Davey uses a robot to distribute microliters of carefully calibrated compounds in batches of small plastic wells containing cells that have been exposed to the virus. A green fluorescent marker is used to involve SARS-CoV-2 in cells; If the color is reduced, a compound would possibly have stopped the reproduction of the virus. So far, Davey told me, the passod fortune rate has been 2.5 consistent with percent, which is high. “Now we want to go back and compare which of those remedies might be remedies,” he said. Three-dimensional virtual molecule modeling allows for even greater efficiency, at least for initial screening. Davey worked with Haribabu Arthanari, a biophysicist at Harvard Medical School, who led a task to analyze billions of chemicals through the computer, of which it was discovered that at least 3,000 have the right shape to have compatibility with key elements of the coronavirus, making them promising. subjects for laboratory studies.
Such collaborations with the wider network of studios are essential for NEIDL’s operation. German virologist Elke Mhlberger, an expert on testing Ebola and Marburg viruses, uses his NEIDL laboratory to conduct studies on SARS-CoV-2 infection for more than a dozen scientists at Massachusetts institutions. Even before the epidemic, she was participating with Darrell Kotton, a specialist in lung medicine and intensive care who runs BU’s Center for Regenerative Medicine, in a generation in which she evolved and which, by the way, has exciting implications for COVID-19 studies. Using stem cell phones, he was able to grow a type of human lung mobile known as a type II pneumote. These mobile phones, which Kotton compares to footballs, seem to be the number one target of SARS-CoV-2, however, they were not in the past to experiment in significant amounts: they live in the pulmonary alveoli and cannot be recovered by primary surgery.
Kotton was impressed by the dramatic disappearance of some COVID-19 patients he attended at the ICU. “They had nothing but what would be called a cold, with fever and colds, but then, after a week or two, and in a few hours, they would crash,” he told me. “And I wondered, what’s going on in the lung? Now we can examine the type II pneocytes over time. We have mobile phones in the lab that can tell us what’s going on.” At NEIDL, I saw photographs of some of those SARS-CoV-2-infected Mobiles in the MA lab to monitor the virus, it was colored with a fluorescent green antibody; after individual mobiles were filled with viruses, they have become bright green-blooded mobiles. According to Kotton, those mobiles can provide a way to practice the habit of the virus in its first interactions with its main target in the lung. “It took me 15 years to grow it in the lab,” he says. Now, researchers from all over the world were calling to ask if you could provide them with mobile cultures to use in their work.
Science is an iterative process, in which each step is based on the successes and errors of the latter. Collective research, the multiple projects based on NEIDL appear to be disparate companies. But collecting a coronavirus symbol requires following many parallel lines of research, while assimilating existing medical knowledge. My own lab has been working with endothelial cells, the cells that line the body’s blood vessels and serve as an opposite barrier to pathogen access, for years, as a component of an effort to improve the effects of H.I.V. In recent months, evidence has emerged suggesting that these cells are also a primary target of coronavirus. Researchers recently published the effects that appear on viral components on the endothelial cells of the frontal lobes of an Italian coronavirus victim, which may potentially be some of the neurological effects of the virus. Other studies have also reported playing a vital role in many other maximum harmful effects of coronavirus, such as kidney failure, stroke and reported inflammatory disease in children. Our lab is now running to decipher how the virus can cause such attacks on endothelial cells, in order to identify tactics to save them.
Modern medical studies are inherently collaborative, however, the constellation of efforts that are being made lately around the world has an unprecedented scale and scope. This dissemination reinforces the price of sales options such as NEIDL, which acts as a center of wisdom. Many services serve some of NEIDL’s purposes, but few combine so many disciplines and approaches under one roof, and even less are also a component of their proactive collaboration with surrounding institutions. This is not a coincidence, but a testament to the price of long-term reflection, even in those times of crisis when speed is on everyone’s mind. As Corley pointed out to me, it reminded me that the explanation of why NEIDL had a diverse but incorporated study team in a position to examine a catastrophic viral epidemic was the foresight of Anthony Fauci’s recommendations after 9/11. “COVID was the raison d’etre of the creation of NEIDL,” Corley said. “The pandemic is fulfilling its mission.”
