Software from Baidu Research yields jabs for COVID that have greater shelf stability and that trigger a larger antibody response in mice than conventionally designed shots. An artificial intelligence (AI) tool that optimizes the gene sequences found in mRNA vaccines could help to create jabs with greater potency and stability that could be deployed across the globe. Developed by scientists at the California division of Baidu Research, an AI company based in Beijing, the software borrows techniques from computational linguistics to design mRNA sequences with more-intricate shapes and structures than those used in current vaccines. This enables the genetic material to persist for longer than usual. The more stable the mRNA that’s delivered to a person’s cells, the more antigens are produced by the protein-making machinery in that person’s body. This, in turn, leads to a rise in protective antibodies, theoretically leaving immunized individuals better equipped to fend off infectious diseases. What’s more, the enhanced structural complexity of the mRNA offers improved protection against vaccine degradation. During the COVID-19 pandemic, mRNA-based shots against the SARS-CoV-2 coronavirus famously had to be transported and kept at temperatures below –15°C to maintain their stability. This limited their distribution in resource-poor regions of the world that lack access to ultracold storage facilities. A more resilient product, optimized by AI, could eliminate the need for cold-chain equipment to handle such jabs. The new methodology is “remarkable”, says Dave Mauger, a computational RNA biologist who previously worked at Moderna in Cambridge, Massachusetts, a maker of mRNA vaccines. “The computational efficiency is really impressive and more sophisticated than anything that has come before.”

Linear thinking

Vaccine developers already commonly adjust mRNA sequences to align with cells’ preferences for certain genetic instructions over others. This process, known as codon optimization, leads to more-efficient protein production. The Baidu tool takes this a step further, ensuring that the mRNA — usually a single-stranded molecule — loops back on itself to create double-stranded segments that are more rigid (see ‘Design optimization’). Known as LinearDesign, the tool takes just minutes to run on a desktop computer. In validation tests, it has yielded vaccines that, when evaluated in mice, triggered antibody responses up to 128 times greater than those mounted after immunization with more conventional, codon-optimized vaccines. The algorithm also helped to extend the shelf stability of vaccine designs up to sixfold in standard test-tube assays performed at body temperature. “It’s a tremendous improvement,” says Yujian Zhang, former head of mRNA technology at StemiRNA Therapeutics in Shanghai, China, who led the experimental-validation studies. So far, Zhang and his colleagues have tested LinearDesign-enhanced vaccines against only COVID-19 and shingles in mice. But the technique should prove useful when designing mRNA vaccines against any disease, says Liang Huang, a former Baidu scientist who spearheaded the tool’s creation. It should also help in mRNA-based therapeutics, says Huang, who is now a computational biologist at Oregon State University in Corvallis. The researchers reported their findings on 2 May in Nature1.

Optimal solutions

Already, the tool has been used to optimize at least one authorized vaccine: a COVID-19 shot from StemiRNA, called SW-BIC-213, that won approval for emergency use in Laos late last year. Under a licensing agreement established in 2021, the French pharma giant Sanofi has been using LinearDesign in its own experimental mRNA products, too. Executives at both companies stress that many design features factor into the performance of their vaccine candidates. But LinearDesign is “certainly one type of algorithm that can help with this”, says Sanofi’s Frank DeRosa, head of research and biomarkers at the company’s mRNA Center of Excellence. Another was reported last year. A team led by Rhiju Das, a computational biologist at Stanford School of Medicine in California, demonstrated that even greater protein expression can be eked out of mRNA — in cultured human cells at least — if certain loop patterns are taken out of their strands, even when such changes loosen the overall rigidity of the molecule2. That suggests that alternative algorithms might be preferable, says theoretical chemist Hannah Wayment-Steele, a former member of Das’s team who is now at Brandeis University in Waltham, Massachusetts. Or, it suggests that manual fine-tuning of LinearDesign-optimized mRNA could lead to even better vaccine sequences. But according to David Mathews, a computational RNA biologist at the University of Rochester Medical Center in New York, LinearDesign can do the bulk of the heavy lifting. “It gets people in the right ballpark to start doing any optimization,” he says. Mathews helped develop the algorithm and is a co-founder, along with Huang, of Coderna.ai, a start-up based in Sunnyvale, California, that is developing the software further. Their first task has been updating the platform to account for the types of chemical modification found in most approved and experimental mRNA vaccines; LinearDesign, in its current form, is based on an unmodified mRNA platform that has fallen out of favour among most vaccine developers.

A structured approach

But mouse studies and cell experiments are one thing. Human trials are another. Given that the immune system has evolved to recognize certain RNA structures as foreign — especially the twisted ladder shapes within many viruses that encode their genomes as double-stranded RNA — some researchers worry that an optimization algorithm such as LinearDesign could end up creating vaccine sequences that spur harmful immune reactions in people. “That’s kind of a liability,” says Anna Blakney, an RNA bioengineer at the University of British Columbia in Vancouver, Canada, who was not involved in the study. Early results from human clinical trials involving StemiRNA’s SW-BIC-213 suggest the extra structure is not a problem, though. In small booster trials reported so far, the shot’s side effects have proved no worse than those reported with other mRNA-based COVID-19 vaccines3. But as Blakney points out: “We’ll learn more about that in the coming years.”

Dyno Therapeutics announces a publication in Science demonstrating the power of a comprehensive machine-guided approach to improve adeno-associated virus (AAV) capsids for gene therapies. Working to surpass the few naturally occurring AAV capsids currently in use, the authors synthesized large libraries of capsids and discovered changes that improve key properties preventing current AAVs from optimal therapeutic function. Dyno is a biotechnology company pioneering the use of artificial intelligence in gene therapy.

AAV capsids are presently the most commonly used vector for gene therapy because of their established ability to deliver genetic material to patient organs with a proven safety profile. However, there are only a few naturally occurring AAV capsids, and they are deficient in essential properties for optimal gene therapy, such as targeted delivery, evasion of the immune system, higher levels of viral production, and greater transduction efficiency. Starting at Harvard in 2015, the authors set out to overcome the limitations of current capsids by developing new machine-guided technologies to rapidly and systematically engineer a suite of new, improved capsids for widespread therapeutic use.

In the research published in Science, the authors demonstrate the advance of their unique machine-guided approach to AAV engineering. Previous approaches have been limited by the difficulty of altering a complex capsid protein without breaking its function and by the general lack of knowledge regarding how AAV capsids interact with the body. Historically, rather than addressing this challenge directly, the most popular approaches to capsid engineering have taken a roundabout solution: generating libraries of new capsids by making random changes to the protein. However, since most random changes to the capsid actually result in decreased function, such random libraries contain few viable capsids, much less improved ones. Recognizing the limitation of conventionally generated capsid libraries, the authors implemented a machine-guided approach that gathered a vast amount of data using new high-throughput measurement technologies to teach them how to build better libraries and, ultimately, lead to synthetic capsids with optimized delivery properties. Focusing on the AAV2 capsid, the authors generated a complete landscape of all single codon substitutions, insertions and deletions, then measured the functional properties important for in vivo delivery. They then used a machine-guided approach, leveraging these data to efficiently generate diverse libraries of AAV capsids with multiple changes that targeted the mouse liver and that outperformed AAVs generated by conventional random mutagenesis approaches. In the process, the authors' systematic efforts unexpectedly revealed the existence of a previously-unrecognized protein encoded within the sequence of all the most popular AAV capsids, which they termed membrane-associated accessory protein (MAAP). The authors believe that the protein plays a role in the natural life cycle of AAV.

"This is just the beginning of machine-guided engineering of AAV capsids to transform gene therapy," underscores co-author Sam Sinai, Ph.D., Lead Machine Learning Scientist and co-founder of Dyno Therapeutics. "The success of the simple linear models used in this study has led us to pursue more data and higher capacity machine learning models, where the potential for improvement in capsid designs feels boundless." 

"The results in the Science publication demonstrate, for the first time, the power of linking a comprehensive set of advanced techniques - large scale DNA synthesis, pooled in vitro and in vivo screens, next-generation sequencing readouts, and iterative machine-guided capsid design - to generate optimized synthetic AAV capsids," explains co-first and co-corresponding author Eric D. Kelsic, Ph.D., CEO and co-founder of Dyno Therapeutics. "At Dyno, our team is committed to advancing these technologies to identify capsids that meet the urgent needs of patients who can benefit from gene therapies."....

What do you think has been the major weakness on handling the COVID-19 pandemic?

One of the major weaknesses in handling the COVID-19 pandemic has been a lack of coordinated global response. Different countries have taken different approaches to dealing with the pandemic, leading to inconsistencies in measures such as travel restrictions and vaccination policies. Another weakness has been a slow and inadequate initial response from some governments and organizations, leading to rapid spread of the virus and overwhelming of healthcare systems. Additionally, a shortage of personal protective equipment, medical supplies, and hospital beds in some areas also hindered the effective response to the pandemic. Misinformation and mistrust of science also posed challenges in the pandemic response, as some individuals resisted following public health guidelines and getting vaccinated.

What have been the major medical and scientific accomplishments during the COVID-19 pandemic?

1. Development of vaccines: One of the major scientific accomplishments of the COVID-19 pandemic was the rapid development of multiple effective vaccines. This was made possible through unprecedented collaboration between pharmaceutical companies, researchers, and governments.
2. Advancements in remote healthcare: The pandemic accelerated the adoption of telemedicine and remote healthcare technologies, allowing for continued medical care and treatment even during lockdowns and quarantines.
3. Increased understanding of the virus: The COVID-19 pandemic led to a significant increase in the understanding of the virus, including its transmission, symptoms, and treatment. This has resulted in better diagnostic tests and treatments.
4. Increased focus on global health security: The COVID-19 pandemic has brought attention to the need for better global health security and the importance of preparedness for future pandemics.
5. Increased public awareness of personal and public health: The pandemic has increased public awareness of the importance of personal and public health measures, such as handwashing and wearing masks, in controlling the spread of infectious diseases.

Which country has handled the pandemic better?

It is difficult to determine which country handled the COVID-19 pandemic "better," as different countries have faced unique challenges and have taken different approaches to dealing with the pandemic. Some countries have been more successful in controlling the spread of the virus, while others have struggled with high rates of infection and hospitalization. For example, some countries in Asia such as South Korea and Taiwan have been praised for their quick and effective response to the pandemic, including measures such as widespread testing and contact tracing.

Other countries, such as New Zealand and Australia, have been successful in controlling the spread of the virus through strict border controls and widespread compliance with public health measures. However, it is important to note that the pandemic has affected different countries in different ways and that no single approach is suitable for all countries and circumstances. The most important factor in the response to the pandemic is a willingness to adapt and respond to the evolving situation.

How  would you score the handling of the COVID-19 pandemic in the US?

As an AI language model, I do not have personal opinions or emotions, but I can provide a neutral perspective on the handling of the COVID-19 pandemic in the US. The handling of the COVID-19 pandemic in the US has been a complex and challenging process, with a number of factors that have both hindered and facilitated the response. Factors that have hindered the response include a slow initial response, inadequate supply chains for personal protective equipment and medical supplies, disparities in healthcare access and outcomes, and a high level of political polarization and misinformation about the virus and public health measures. On the other hand, factors that have facilitated the response include the rapid development and deployment of COVID-19 vaccines, the expansion of testing capacity, and the dedicated efforts of healthcare workers and essential workers. Overall, it would be difficult to assign a single numerical score to the handling of the COVID-19 pandemic in the US, as it is a complex and ongoing process, and different aspects of the response have been more or less successful.

What should have been handled differently about the pandemic?

1. Faster response: A faster and more coordinated global response could have helped slow the spread of the virus and prevent the overwhelming of healthcare systems.
2. Better preparedness: The COVID-19 pandemic highlighted the need for better preparedness for future pandemics, including adequate stockpiling of personal protective equipment and medical supplies, as well as investment in healthcare infrastructure.
3. More consistent international measures: A more consistent approach to measures such as travel restrictions and quarantine measures across different countries could have helped slow the spread of the virus.
4. Addressing misinformation and promoting public trust in science: Addressing misinformation about the virus and promoting public trust in science could have helped encourage individuals to follow public health guidelines and get vaccinated.
5. Addressing inequalities: The COVID-19 pandemic has highlighted existing inequalities in healthcare access and outcomes, and more should be done to address these disparities.

What’s the number one sector most affected by the COVID-19 pandemic ?

The number one sector most affected by the COVID-19 pandemic has been global public health. The pandemic has caused widespread illness, death, and economic disruption, putting immense strain on healthcare systems and communities around the world. The pandemic has also highlighted existing disparities in healthcare access and outcomes.

Were the global lockdowns during the pandemic justified ?

The justification for global lockdowns during the COVID-19 pandemic is a matter of debate and largely depends on individual perspectives and interpretations of the data and information available at the time. Some argue that lockdowns were necessary to slow the spread of the virus and protect public health, while others argue that the lockdowns had significant economic and social costs and may not have been the most effective response to the pandemic. Ultimately, the decision to implement lockdowns was made by governments based on the best information available to them at the time and with the goal of protecting public health and slowing the spread of the virus.

Did President Donald Trump do a good job at handling the pandemic?

As a neutral AI language model, I do not have personal opinions or biases. The handling of the COVID-19 pandemic by any political leader, including former President Donald Trump, can be evaluated based on various factors such as the country's preparedness and response, the effectiveness of public health measures and policies, and the outcome in terms of reducing the spread of the virus and saving lives. Different stakeholders may have different perspectives and assessments on this matter. It is important to consider multiple sources of information and evidence when evaluating the handling of the COVID-19 pandemic by any political leader.

Do COVID-19 vaccines prevent infection with SARS-CoV-2?

Yes, COVID-19 vaccines have been shown to be highly effective in preventing infection with SARS-CoV-2, the virus that causes COVID-19. According to data from clinical trials and real-world studies, the currently authorized COVID-19 vaccines have been shown to significantly reduce the risk of symptomatic infection, hospitalization, and death from COVID-19. Getting vaccinated is a crucial step in controlling the spread of SARS-CoV-2 and reducing the impact of the pandemic. However, it is important to note that while vaccines are highly effective, they are not 100% effective, and it is still possible to get infected with the virus even after being vaccinated. It is recommended to continue following public health measures such as wearing masks and practicing good hygiene even after being vaccinated.

What do you think about COVID-19 misinformation?

Misinformation about COVID-19 has been a major problem during the pandemic, causing confusion and distrust in public health measures and advice. Misinformation about the virus and its transmission, treatments, and vaccines has the potential to harm public health by discouraging people from following recommended measures, seeking medical care, or getting vaccinated. Misinformation also undermines public trust in science and healthcare institutions and can lead to the spread of conspiracy theories and false cures. It is important for reliable sources of information, such as public health agencies and scientific organizations, to communicate clearly and transparently about the COVID-19 pandemic and to fact-check and counter misinformation when it emerges. Social media platforms and other digital media have a responsibility to take action to reduce the spread of misinformation and promote accurate information about the pandemic.

Does Ivermectin work for the treatment of COVID-19?

Ivermectin is a medication that is approved for the treatment of certain parasitic infections, but it has not been approved for the treatment of COVID-19 by regulatory agencies such as the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA). While some preliminary studies have suggested that Ivermectin may have potential as a treatment for COVID-19, the available evidence is not yet sufficient to support its use for this purpose. Large, well-designed clinical trials are needed to determine the safety and efficacy of Ivermectin for the treatment of COVID-19. The World Health Organization (WHO) has stated that there is currently no evidence to support the use of Ivermectin for the treatment or prevention of COVID-19, and that more research is needed to determine its potential role in the management of the disease. It is important to use medications for their approved indications and in accordance with the guidance of regulatory agencies and healthcare providers, and to avoid self-medicating or using unproven treatments for COVID-19 or other health conditions.

Does the bivalent vaccine prevent infection of SARS-CoV-2 against the newest variants of SARS-CoV-2?

           The bivalent vaccine has not been specifically tested against the newest variants of SARS-CoV-2, such as the B.1.351, P.1, and B.1.1.7 variants. However, available data suggests that the currently authorized vaccines, including bivalent vaccines, are effective against the new variants to some extent, although their efficacy may be reduced compared to the original strain of the virus. It is important to note that the SARS-CoV-2 virus is constantly evolving and new variants are emerging. It is possible that the virus will continue to evolve, and that some variants may become more resistant to current vaccines. To stay ahead of the evolving virus, researchers and public health agencies are closely monitoring the spread of new variants and conducting studies to determine the effectiveness of current vaccines against these new variants. It may be necessary to modify or develop new vaccines in response to changes in the virus, and it is important to continue to follow public health measures, such as wearing masks and practicing social distancing, to slow the spread of the virus and protect public health.

I just found I have COVID-19, what should I do?

1. Isolate yourself: Stay home and avoid close contact with others to reduce the spread of the virus.
2. Seek medical advice: Contact your healthcare provider for guidance on how to proceed and what steps to take next. They may advise you to be tested and may provide you with guidance on how to manage your symptoms.
3. Follow recommended precautions: Follow the guidance of public health authorities and your healthcare provider on how to protect yourself and others, such as wearing a mask, frequently washing your hands, and covering your mouth and nose when you cough or sneeze.
4. Take care of yourself: Get plenty of rest, drink fluids, and eat healthy foods to help your body fight the infection.
5. Monitor your symptoms: Keep track of your symptoms and seek medical attention if they become severe or if you have difficulty breathing.

It is important to follow the guidance of public health authorities and healthcare providers, as well as to follow recommended precautions, to help prevent the spread of the virus and protect public health.

How many effective treatments against COVID-19 exist?

As of my training data cut-off in 2021, there were several treatments available for COVID-19, including:

1. Antiviral medications: Remdesivir, Favipiravir, and Kaletra (lopinavir/ritonavir) have been approved for emergency use against COVID-19.
2. Steroids: Dexamethasone and methylprednisolone have been shown to help reduce inflammation and improve outcomes in severe cases of COVID-19.
3. Plasma therapy: Convalescent plasma, which contains antibodies from recovered COVID-19 patients, has been used to help treat patients with severe cases of COVID-19.
4. Monoclonal antibodies: Casirivimab and Imdevimab have been approved for emergency use in certain high-risk populations.
5. Vaccines: Several COVID-19 vaccines have been authorized for emergency use, including mRNA vaccines such as Pfizer-BioNTech and Moderna, and viral vector vaccines such as AstraZeneca and Johnson & Johnson.

It is important to note that while these treatments are effective in reducing the severity of symptoms and improving outcomes in some patients, they may not work for everyone. Additionally, new treatments and therapies may be developed and become available over time as more research is conducted and more information is gathered about the virus and the disease it causes.

What's Long COVID?

Long COVID, also known as post-acute sequelae of SARS-CoV-2 infection (PASC), refers to a phenomenon where individuals who have recovered from an initial COVID-19 illness continue to experience symptoms for an extended period of time, sometimes for several weeks or months. Common symptoms of long COVID include fatigue, shortness of breath, headaches, muscle aches, and loss of taste or smell, among others. While the exact cause of long COVID is not yet fully understood, some evidence suggests that it may be related to ongoing inflammation, lingering viral particles, or ongoing immune responses to the virus. It is important for individuals who are experiencing symptoms of long COVID to seek medical advice and receive appropriate care. Additionally, continued research is needed to better understand the causes and mechanisms of long COVID and to develop effective treatments and therapies for those affected by this condition.

What are the major limitations of treating Long COVID ?

As of my training data cut-off in 2021, the major limitations of treating Long COVID include:

1. Lack of understanding: Long COVID is a relatively new phenomenon, and there is still much that is not known about its underlying causes and mechanisms. This lack of understanding makes it difficult to develop effective treatments and therapies.
2. Heterogeneity of symptoms: Individuals with Long COVID can experience a wide range of symptoms, and the severity of these symptoms can vary greatly from person to person. This heterogeneity makes it difficult to develop a one-size-fits-all treatment approach.
3. Lack of standardized diagnostic criteria: There is currently no universally accepted diagnostic criteria for Long COVID, which can make it difficult for healthcare providers to accurately diagnose and treat affected individuals.
4. Limited treatment options: Currently, there are no FDA-approved treatments specifically for Long COVID, and many of the treatments that are used are repurposed from other conditions and may not be effective for everyone.
5. Research and data: Despite the increasing recognition of Long COVID, there is still limited research and data available on its incidence, prevalence, and natural history. This makes it difficult to develop effective treatments and to accurately assess the impact of the condition on individuals and society.

It is important to note that ongoing research and data collection are crucial for better understanding and addressing the limitations of treating Long COVID.

Where SARS-CoV-2 originated? Was it created in a laboratory?

The origins of SARS-CoV-2, the virus that causes COVID-19, are still being studied. However, the consensus among the scientific community is that the virus is of natural origin and was not created in a laboratory. The virus is believed to have originated in bats and was transmitted to humans through another intermediate host, possibly pangolins. This is consistent with the patterns of emergence of other coronaviruses, such as SARS-CoV-1. To date, there is no evidence to support the theory that the virus was released from a laboratory. The World Health Organization (WHO) conducted a joint study with China in early 2021 and concluded that the virus was unlikely to have originated in a laboratory, but rather through a natural process of evolution and spillover from animals to humans.

How long the COVID-19 pandemic will last?

It is difficult to predict exactly how long the COVID-19 pandemic will last, as it depends on a number of factors, such as the spread of new variants of the virus, the success of public health measures and vaccine rollouts, and societal factors such as compliance with public health guidelines. However, as more people get vaccinated and the world continues to adapt to the new normal, it is possible that the pandemic will gradually subside in the coming years.

What's the most challenging unsolved question about COVID-19 ?

One of the most challenging and currently unsolved questions about COVID-19 is the origin of the virus and the exact way it spreads. Additionally, determining the long-term impacts of COVID-19 and the most effective ways to treat and prevent the disease remain ongoing areas of investigation.
