Experimental mRNA Vaccine May Protect Against All 20 Influenza Virus Subtypes
Posted on by Lawrence Tabak, D.D.S., Ph.D.
Flu season is now upon us, and protecting yourself and loved ones is still as easy as heading to the nearest pharmacy for your annual flu shot. These vaccines are formulated each year to protect against up to four circulating strains of influenza virus, and they generally do a good job of this. What they can’t do is prevent future outbreaks of more novel flu viruses that occasionally spill over from other species into humans, thereby avoiding a future influenza pandemic.
On this latter and more-challenging front, there’s some encouraging news that was published recently in the journal Science . An NIH-funded team has developed a unique “universal flu vaccine” that, with one seasonal shot, that has the potential to build immune protection against any of the 20 known subtypes of influenza virus and protect against future outbreaks.
While this experimental flu vaccine hasn’t yet been tested in people, the concept has shown great promise in advanced pre-clinical studies. Human clinical trials will hopefully start in the coming year. The researchers don’t expect that this universal flu vaccine will prevent influenza infection altogether. But, like COVID-19 vaccines, the new flu vaccine should help to reduce severe influenza illnesses and deaths when a person does get sick.
So, how does one develop a 20-in-1“multivalent” flu vaccine? It turns out that the key is the same messenger RNA (mRNA) technology that’s enabled two of the safe and effective vaccines against COVID-19, which have been so instrumental in fighting the pandemic. This includes the latest boosters from both Pfizer and Moderna, which now offer updated protection against currently circulating Omicron variants.
While this isn’t the first attempt to develop a universal flu vaccine, past attempts had primarily focused on a limited number of conserved antigens. An antigen is a protein or other substance that produces an immune response. Conserved antigens are those that tend to stay the same over time.
Because conserved antigens will look similar in many different influenza viruses, the hope was that vaccines targeting a small number of them would afford some broad influenza protection. But the focus on a strategy involving few antigens was driven largely by practical limitations. Using traditional methods to produce vaccines by growing flu viruses in eggs and isolating proteins, it simply isn’t feasible to include more than about four targets.
That’s where recent advances in mRNA technology come in. What makes mRNA so nifty for vaccines is that all you need to know is the letters, or sequence, that encodes the genetic material of a virus, including the sequences that get translated into proteins.
A research team led by Scott Hensley, Perelman School of Medicine at the University of Pennsylvania, Philadelphia, recognized that the ease of designing and manufacturing mRNA vaccines opened the door to an alternate approach to developing a universal flu vaccine. Rather than limiting themselves to a few antigens, the researchers could make an all-in-one influenza vaccine, encoding antigens from every known influenza virus subtype.
Influenza vaccines generally target portions of a plentiful protein on the viral surface known as hemagglutinin (H). In earlier work, Hensley’s team, in collaboration with Perelman’s mRNA vaccine pioneer Drew Weissman, showed they could use mRNA technology to produce vaccines with H antigens from single influenza viruses [2, 3]. To protect the fragile mRNA molecules that encode a selected H antigen, researchers deliver them to cells inside well-tolerated microscopic lipid shells, or nanoparticles. The same is true of mRNA COVID-19 vaccines. In their earlier studies, the researchers found that when an mRNA vaccine aimed at one flu virus subtype was given to mice and ferrets in the lab, their cells made the encoded H antigen, eliciting protective antibodies.
In this latest study, they threw antigens from all 20 known flu viruses into the mix. This included H antigens from 18 known types of influenza A and two lineages of influenza B. The goal was to develop a vaccine that could teach the immune system to recognize and respond to any of them.
More study is needed, of course, but early indications are encouraging. The vaccine generated strong and broad antibody responses in animals. Importantly, it worked both in animals with no previous immunity to the flu and in those previously infected with flu viruses. That came as good news because past infections and resulting antibodies sometimes can interfere with the development of new antibodies against related viral subtypes.
In more good news, the researchers found that vaccinated mice and ferrets were protected against severe illness when later challenged with flu viruses. Those viruses included some that were closely matched to antigens in the vaccine, along with some that weren’t.
The findings offer proof-of-principle that mRNA vaccines containing a wide range of antigens can offer broad protection against influenza and likely other viruses as well, including the coronavirus strains responsible for COVID-19. The researchers report that they’re moving toward clinical trials in people, with the goal of beginning an early phase 1 trial in the coming year. The hope is that these developments—driven in part by technological advances and lessons learned over the course of the COVID-19 pandemic—will help to mitigate or perhaps even prevent future pandemics.

Millions of Single-Cell Analyses Yield Most Comprehensive Human Cell Atlas Yet
Posted on by Lawrence Tabak, D.D.S., Ph.D.
There are 37 trillion or so cells in our bodies that work together to give us life. But it may surprise you that we still haven’t put a good number on how many distinct cell types there are within those trillions of cells.
That’s why in 2016, a team of researchers from around the globe launched a historic project called the Human Cell Atlas (HCA) consortium to identify and define the hundreds of presumed distinct cell types in our bodies. Knowing where each cell type resides in the body, and which genes each one turns on or off to create its own unique molecular identity, will revolutionize our studies of human biology and medicine across the board.
Since its launch, the HCA has progressed rapidly. In fact, it has already reached an important milestone with the recent publication in the journal Science of four studies that, together, comprise the first multi-tissue drafts of the human cell atlas. This draft, based on analyses of millions of cells, defines more than 500 different cell types in more than 30 human tissues. A second draft, with even finer definition, is already in the works.
Making the HCA possible are recent technological advances in RNA sequencing. RNA sequencing is a topic that’s been mentioned frequently on this blog in a range of research areas, from neuroscience to skin rashes. Researchers use it to detect and analyze all the messenger RNA (mRNA) molecules in a biological sample, in this case individual human cells from a wide range of tissues, organs, and individuals who voluntarily donated their tissues.
By quantifying these RNA messages, researchers can capture the thousands of genes that any given cell actively expresses at any one time. These precise gene expression profiles can be used to catalogue cells from throughout the body and understand the important similarities and differences among them.
In one of the published studies, funded in part by the NIH, a team co-led by Aviv Regev, a founding co-chair of the consortium at the Broad Institute of MIT and Harvard, Cambridge, MA, established a framework for multi-tissue human cell atlases . (Regev is now on leave from the Broad Institute and MIT and has recently moved to Genentech Research and Early Development, South San Francisco, CA.)
Among its many advances, Regev’s team optimized single-cell RNA sequencing for use on cell nuclei isolated from frozen tissue. This technological advance paved the way for single-cell analyses of the vast numbers of samples that are stored in research collections and freezers all around the world.
Using their new pipeline, Regev and team built an atlas including more than 200,000 single-cell RNA sequence profiles from eight tissue types collected from 16 individuals. These samples were archived earlier by NIH’s Genotype-Tissue Expression (GTEx) project. The team’s data revealed unexpected differences among cell types but surprising similarities, too.
For example, they found that genetic profiles seen in muscle cells were also present in connective tissue cells in the lungs. Using novel machine learning approaches to help make sense of their data, they’ve linked the cells in their atlases with thousands of genetic diseases and traits to identify cell types and genetic profiles that may contribute to a wide range of human conditions.
By cross-referencing 6,000 genes previously implicated in causing specific genetic disorders with their single-cell genetic profiles, they identified new cell types that may play unexpected roles. For instance, they found some non-muscle cells that may play a role in muscular dystrophy, a group of conditions in which muscles progressively weaken. More research will be needed to make sense of these fascinating, but vital, discoveries.
The team also compared genes that are more active in specific cell types to genes with previously identified links to more complex conditions. Again, their data surprised them. They identified new cell types that may play a role in conditions such as heart disease and inflammatory bowel disease.
Two of the other papers, one of which was funded in part by NIH, explored the immune system, especially the similarities and differences among immune cells that reside in specific tissues, such as scavenging macrophages [2,3] This is a critical area of study. Most of our understanding of the immune system comes from immune cells that circulate in the bloodstream, not these resident macrophages and other immune cells.
These immune cell atlases, which are still first drafts, already provide an invaluable resource toward designing new treatments to bolster immune responses, such as vaccines and anti-cancer treatments. They also may have implications for understanding what goes wrong in various autoimmune conditions.
Scientists have been working for more than 150 years to characterize the trillions of cells in our bodies. Thanks to this timely effort and its advances in describing and cataloguing cell types, we now have a much better foundation for understanding these fundamental units of the human body.
But the latest data are just the tip of the iceberg, with vast flows of biological information from throughout the human body surely to be released in the years ahead. And while consortium members continue making history, their hard work to date is freely available to the scientific community to explore critical biological questions with far-reaching implications for human health and disease.

Teaching the Immune System to Attack Cancer with Greater Precision
Posted on by Dr. Francis Collins
To protect humans from COVID-19, the Pfizer and Moderna mRNA vaccines program human cells to translate the injected synthetic messenger RNA into the coronavirus spike protein, which then primes the immune system to arm itself against future appearances of that protein. It turns out that the immune system can also be trained to spot and attack distinctive proteins on cancer cells, killing them and leaving healthy cells potentially untouched.
While these precision cancer vaccines remain experimental, researchers continue to make basic discoveries that move the field forward. That includes a recent NIH-funded study in mice that helps to refine the selection of protein targets on tumors as a way to boost the immune response . To enable this boost, the researchers first had to discover a possible solution to a longstanding challenge in developing precision cancer vaccines: T cell exhaustion.
The term refers to the immune system’s complement of T cells and their capacity to learn to recognize foreign proteins, also known as neoantigens, and attack them on cancer cells to shrink tumors. But these responding T cells can exhaust themselves attacking tumors, limiting the immune response and making its benefits short-lived.
In this latest study, published in the journal Cell, Tyler Jacks and Megan Burger, Massachusetts Institute of Technology, Cambridge, help to explain this phenomenon of T cell exhaustion. The researchers found in mice with lung tumors that the immune system initially responds as it should. It produces lots of T cells that target many different cancer-specific proteins.
Yet there’s a problem: various subsets of T cells get in each other’s way. They compete until, eventually, one of those subsets becomes the dominant T cell type. Even when those dominant T cells grow exhausted, they still remain in the tumor and keep out other T cells, which might otherwise attack different neoantigens in the cancer.
Building on this basic discovery, the researchers came up with a strategy for developing cancer vaccines that can “awaken” T cells and reinvigorate the body’s natural cancer-fighting abilities. The strategy might seem counterintuitive. The researchers vaccinated mice with neoantigens that provide a weak but encouraging signal to the immune cells responsible for presenting the distinctive cancer protein target, or antigen, to T cells. It’s those T cells that tend to get suppressed in competition with other T cells.
When the researchers vaccinated the mice with one of those neoantigens, the otherwise suppressed T cells grew in numbers and better targeted the tumor. What’s more, the tumors shrank by more than 25 percent on average.
Research on this new strategy remains in its early stages. The researchers hope to learn if this approach to cancer vaccines might work even better when used in combination with immunotherapy drugs, which unleash the immune system against cancer in other ways.
It’s also possible that the recent and revolutionary success of mRNA vaccines for preventing COVID-19 actually could help. An important advantage of mRNA is that it’s easy for researchers to synthesize once they know the specific nucleic acid sequence of a protein target, and they can even combine different mRNA sequences to make a multiplex vaccine that primes the immune system to recognize multiple neoantigens. Now that we’ve seen how well mRNA vaccines work to prompt a desired immune response against COVID-19, this same technology can be used to speed the development and testing of future vaccines, including those designed precisely to fight cancer.

Meet an Inspiring Researcher Who Helped Create COVID-19 mRNA Vaccines
Posted on by Dr. Francis Collins
More than 170 million Americans already have received COVID-19 vaccines. As this number continues to grow and expand to younger age groups, I’m filled with overwhelming gratitude for all of the researchers who worked so diligently, over the course of decades, to build the scientific foundation for these life-saving vaccines. One of them is Dr. Kizzmekia Corbett, who played a central role in the fact that, in the span of less than a year, we were able to develop safe and effective mRNA-based vaccines to protect against this devastating infectious disease.
As leader of the immunopathogenesis team at NIH’s Dale and Betty Bumpers Vaccine Research Center in Bethesda, MD, Dr. Corbett was ready, willing, and able when the COVID-19 pandemic emerged to take the critical first steps in developing what would become the Moderna and Pfizer/BioNTech mRNA vaccines. Recently, she accepted a position at Harvard University T.H. Chan School of Public Health, Boston, where she will soon open her own viral immunology lab to help inform future vaccine development for coronaviruses and other respiratory viruses.
While she was preparing for her move to Harvard, I had a chance to speak with Dr. Corbett about her COVID-19 research experience and what it was like to get immunized with the vaccine that she helped to create. Our conversation was part of an NIH Facebook Live event in which we connected virtually from our homes in Maryland. Here is a condensed version of our chat.
Collins: You’ve studied SARS, MERS, and other coronaviruses for many years. Then, in early January 2020, like all of us, you heard that something was going on that sounded worrisome in Wuhan, China. What did you think?
Corbett: Well, the story actually began for me on December 31, 2019. My boss Dr. Barney Graham sent me an email at 6 a.m. that said: “Get ready for 2020.” There had been some news of a respiratory virus outbreak in the Wuhan district of China. I honestly wrote it off as probably a strain of the flu. Then, we got back to NIH after the holidays, and it was determined around January 6 that the virus was for certain a coronavirus. That meant our team would be responding to it.
We sat down and planned to monitor the situation very closely. We knew exactly what to do, based on our past work. We would go into full force to make a vaccine—the one now known as “the Moderna vaccine” —as quickly as possible for testing in a clinical trial. The goal was to make the vaccine in 100 days. And so when the genetic sequence of this new virus came out on January 10, I sprung out of bed and so did everyone on the team. It’s been kind of a whirlwind ever since.
Collins: Tell us a little bit more about that. The sequence got posted on the internet by a Chinese scientist. So you have this sequence, and everyone gathers in NIH’s Vaccine Research Center. Then what happens?
Corbett: The cool thing about this type of technology is you don’t even need the lab to design the vaccine. All you need are the letters, or sequence, that encodes the virus’ genetic material displayed on your computer screen. We could actually do the work from our homes, obviously in close conversation with each other.
This sequence is the virus’s genetic code. Just like humans have families—brothers, sisters, cousins—viruses also have families. So, we could see when looking at the sequence of letters, how similar this particular virus was to viruses that we’ve worked with before in the coronavirus family. It was almost like “A-ha! This is the part of the sequence that represents the protein on the surface of the virus.”
We knew that we could take the sequence of that surface protein and use all of the knowledge that we had from previous years to design a vaccine. And that’s what we did. We took that sequence on our computer screen and said we said this is exactly how we want this vaccine to look. The process was as straightforward as that.
Collins: In other words, you already knew that these coronaviruses have spike proteins on their surface and that’s the thing that’s going to be really useful for making an antibody. You’d already taken this approach in developing a vaccine for MERS, right?
Corbett: Exactly, we’d done that for MERS. Vaccines are basically a way to teach your body how to see a pathogen. Over the years, as vaccinology and technology have progressed, different scientists have figured out that you don’t really need the whole virus as a part of the vaccine. You can just take a small portion of that virus to alert your body.
In this case, taking the spike protein and teaching your immune system how to specifically spot and attack it, you can now protect yourself from COVID-19. So, we used the sequence of that spike protein, with some modifications to make it much better as a vaccine. We then deliver that to you as a message—messenger RNA (mRNA) —to get your muscle cells briefly to make the spike protein. Then, your body sees that spike protein hanging out on your cells and makes a really specific immune response to it. That way the next time your body sees the spike protein, if you ever come into contact with the virus, your immune system is armed and ready to attack.
Collins: Say more about this messenger RNA approach. It’s been so revolutionary and one of the reasons that we got vaccines into people’s arms in just 11 months. Had this approach ever been used before?
Corbett: Yes, messenger RNA technologies have been in development from a basic science perspective for over 15 years. A lot of that work was funded by NIH. Soon after I got to NIH, I attended a meeting in London called Transforming Vaccinology. At the time, Moderna was a smaller company that was working to make messenger RNA technologies, mostly centered around cancer therapies. But they had started to test some flu vaccines that used messenger RNA. My question to the presenter was: “Every single time I see you guys present, it looks like mRNA technology has always worked. Can you tell me a time that it hasn’t?” And he said, “I can’t.”
So, our understanding of how this technology works to make really good vaccines predates this pandemic. I think one of the worries that many people have is how fast and how new this technology is. But all science is compounded knowledge—everything builds on itself.
Collins: Right! We only learned about messenger RNA, because back in the 1950s and 1960s, some researchers decided to figure out how the information in our genetic instruction book, our DNA, can ultimately turn into proteins. It turned out that the message that carries that information is made of RNA.
So, you knew which kinds of letters to program into the messenger RNA vaccine. Would you explain how this vaccine, its messenger RNA, produces a spike protein. Where does that step happen?
Corbett: Your cells are machines built for this kind of thing. I like to remind people that, on a day-in, day-out basis, our cells make proteins—all of the hormones and other things our bodies needs to survive. So, we’re not teaching the cells to do anything different than they would normally do. That’s important to understand.
The way that cells do this is by reading the mRNA sequence. As they’re reading that sequence, they chew it up, like eating it, and say, “Okay, this sequence is for this very specific protein.” Then, they make that protein and push it to the surface of your cells. That’s how it happens.
Collins: And for mRNA vaccines, that’s the point when your immune system says “Wait a minute! I don’t recognize that as part of me, so I’ve got to make an antibody to it.” Then you’re off to the races and develop your immunity. Now that this mRNA vaccine strategy has succeeded for COVID-19, could it be applied to other infectious diseases or even non-infectious conditions?
Corbett: Yes, I heard that about 60 new companies have sprouted up in the last year around messenger RNA technology. They have ideas for different types of infectious disease vaccines and cancer therapies. I expect that this technology will be transformative to medicine in general.
Collins: Here’s a question from social media: “Why does it take two shots for the Pfizer and the Moderna mRNA vaccines? Why isn’t one good enough?”
Corbett: The way that these vaccines work is much like an alarm clock. Imagine your immune system is in bed and the first shot is the alarm clock going off to say, “Hey, wake up and get ready.” And just like I did this morning, the immune system pressed snooze and took a little nap. But when you hear the alarm clock the second time, it’s like someone rushing into your room and pouring a cold bucket of water on you. You have no choice but to get out of bed.
That’s what the second dose of the vaccine does. It pushes your immune response to the next level. That’s why you need two shots to get the type of efficacy that you want and be fully protected for the optimal immune response.
Collins: You were a co-leader of the team that created what became the Moderna vaccine—and you ended up getting immunized with the Moderna vaccine. What did that feel like?
Corbett: It was pretty surreal. I cried. At the end of it, I felt a lot of relief after getting my vaccine, particularly after getting the second dose. There was this breath of fresh air. It was also a birthday present. I got my second dose the day before my 35th birthday, as a birthday present to myself.
Collins: I have to admit, I cried a little bit too after my second dose. It’s just the sense of relief and incredible gratitude that we’ve reached this point. Here we are with vaccines that have 95 percent effectiveness and an incredibly good safety record, which is almost better than we could have hoped for. I’m a person of faith, so there were a lot of my prayers that went into this and it sure felt like they got answered.
Corbett: Yes, same.
Collins: You are out there a lot talking to people about the vaccines. There are still about 100 million Americans that have not yet received their first dose. Many of them still unsure about getting vaccinated. What do you say to those who are on the fence?
Corbett: In this past year, I’ve spent a lot of time talking about the vaccine with people in the community. One thing that I realized, is that I don’t need to say anything unless I’m asked. I think it’s important that I listen first, instead of just speaking.
So I do that, and I try to answer people’s inquiries as specifically as possible. But people have some very broad questions. One thing that is happening is people are seeing vaccines being developed right before their eyes. That can be a little confusing. I try to explain the process, how we went from the preclinical stage all the way to the point of getting the vaccine to hundreds of millions of people. I explain how each step along the way is very highly vetted by regulatory agencies and data safety monitoring committees. I also tell them that the monitoring continues. People from the clinical trials are still being evaluated, and there’s monitoring in the real world as the vaccine is being rolled out. I think that all of those things are really important for people to know.
Collins: Another question from social media: “As a successful scientist, what advice would you give to people who are thinking about a career in science?”
Corbett: If you think you’re interested, you just have to start. There are internship programs, there are scholarship programs, there are shadowing programs all over this country and even globally that can help you get your feet wet. I think the first thing that you want to do with any career is to figure out whether or not you like it. The only way that you can do that is to just explore, explore, explore.
Collins: Didn’t you kind of roll up your sleeves and take the plunge at a young age?
Corbett: Yes, at age 16, I went off and did summer internships at the University of North Carolina. I was able to see first-hand the day-to-day life of science and what being a scientist would look like. That was really important for me. That’s what I mean by exploring.
Collins: And a follow-up question: “Is the biomedical research community welcoming to women of color?”
Corbett: Not always, frankly. I was very fortunate to have been under the wings of a lot of mentors and advocates, who have helped to advance my career to where it is now. I had great mentors at NIH. My graduate school mentor was amazing, and my main collaborator in the coronavirus field was on my dissertation committee. Even prior to this pandemic, when I was doing work that was very obscure, he checked on me very often and made sure that he had a sense of where I wanted to go and how he could help me get there, including collaborating with me.
That kind of thing is very important, particularly for women of color or anyone from a marginalized community. That’s because there will be a point where there might be a glass ceiling. Unfortunately, we don’t necessarily have the tools to break those just yet. So, someone else is going to have to break those down, and most often than not, that person is going to have to be a white man. Finding those people who are allies with you and joining in your fight for your career trajectory is very helpful.
I remember when I was choosing a college, it was a very difficult decision for me. I got accepted into Ivy League schools, and I’d gone to all of the scholarship weekends all over the country. When I was making the decision, my dad said, “Kizzy, just always go where there is love.”
That really sticks to me with every single choice that I make around my career. You want to be at a place that’s welcoming, a place that understands you, and a place that fosters the next version of who you are destined to be. You need to make sure to step back outside of the day-to-day stuff and say, “Okay, does this place love me and people like me?” It’s important to remember that’s how you thrive: when you are comfortable in and in love with your environment.
Collins: Yes, we have to move our scientific workforce into a place where it is not necessary for a white man to advocate for a talented Black woman. There’s something very wrong with that particular circumstance. As NIH Director, I want to assure you, we are motivated more than ever to change that, including through a new initiative called UNITE. We’re missing out on welcoming the talents of so many folks who currently don’t see our research agenda as theirs, and we need to change that.
Kizzmekia, this has been a lot of fun. Thank you for giving us a half-hour of your time when you’re in the midst of this crazy two-week period of moving from Bethesda to Boston. We wish you the very best for this next chapter, which I know is going to be just amazing.
Corbett: Thank you so much.
