New test may predict COVID-19 immunity
Last Updated on June 1, 2024 by Daily News Staff
The paper test measures the level of neutralizing antibodies in a blood sample and could help people decide what protections they should take against infection.
Newswise — CAMBRIDGE, MA — Most people in the United States have some degree of immune protection against Covid-19, either from vaccination, infection or a combination of the two. But, just how much protection does any individual person have?
MIT researchers have now developed an easy-to-use test that may be able to answer that question. Their test, which uses the same type of “lateral flow” technology as most rapid antigen tests for Covid-19, measures the level of neutralizing antibodies that target the SARS-CoV-2 virus in a blood sample.
Easy access to this kind of test could help people determine what kind of precautions they should take against Covid infection, such as getting an additional booster shot, the researchers say. They have filed for a patent on the technology and are now hoping to partner with a diagnostic company that could manufacture the devices and seek FDA approval.
“Among the general population, many people probably want to know how well protected they are,” says Hojun Li, the Charles W. and Jennifer C. Johnson Clinical Investigator at MIT’s Koch Institute for Integrative Cancer Research. “But I think where this test might make the biggest difference is for anybody who is receiving chemotherapy, anybody who’s on immunosuppressive drugs for rheumatologic disorders or autoimmune diseases, and for anybody who’s elderly or doesn’t mount good immune responses in general. These are all people who might need to be boosted sooner or receive more doses to achieve adequate protection.”
The test is designed so that different viral spike proteins can be swapped in, allowing it to be modified to detect immunity against any existing or future variant of SARS-CoV-2, the researchers say.
Li, who is also an attending physician at the Dana-Farber/Boston Children’s Cancer and Blood Disorders Center, is the senior author of the study, which appears online today in Cell Reports Methods. Guinevere Connelly, a former Koch Institute research technician who is now a graduate student at Duke University, and Orville Kirkland, a research support associate at the Koch Institute, are the lead authors of the paper.
A simple test
Li, who joined the Koch Institute in the fall of 2019, studies blood cell development and how blood cells become cancerous. When SARS-CoV-2 emerged, he started thinking about ways to help combat the pandemic. Many other researchers were already working on diagnostic tests for infection, so he turned his attention to developing a test that would reveal how much immune protection someone has against Covid-19.
Currently, the gold standard approach to measuring immunity involves mixing a blood sample with live virus and measuring how many cells in the sample are killed by the virus. That procedure is too hazardous to perform in most labs, so the more commonly used approaches involve noninfectious modified “pseudoviral” particles, or they are based on a test called ELISA (enzyme-linked immunosorbent assay), which can detect antibodies that neutralize a fragment of a viral protein.
However, these approaches still require trained personnel working in a lab with specialized equipment, so they aren’t practical for use in a doctor’s office to get immediate results. Li wanted to come up with something that could be easily used by a health care provider or even by people at home. He drew inspiration from at-home pregnancy tests, which are based on a type of test called a lateral flow assay.
Lateral flow assays generally consist of paper strips embedded with test lines that bind to a particular target molecule if it is present in a sample. This technology is also the basis of most at-home rapid tests for Covid-19.
Li did not have experience working with this type of test, so he reached out to two MIT faculty members with expertise in devising diagnostics based on lateral flow assays: Hadley Sikes, an associate professor of chemical engineering, and Sangeeta Bhatia, the John and Dorothy Wilson Professor of Health Sciences and Technology and of Electrical Engineering and Computer Science, and a member of the Koch Institute.
With their help, his lab developed a device that can detect the presence of antibodies that block the SARS-CoV-2 receptor binding domain (RBD) from binding to ACE2, the human receptor that the virus uses to infect cells.
The first step in the test is to mix human blood samples with viral RBD protein that has been labeled with tiny gold particles that can be visualized when bound to a paper strip. After allowing time for antibodies in the sample to interact with the viral protein, a few drops of the sample are placed on a test strip embedded with two test lines.
One of these lines attracts free viral RBD proteins, while the other attracts any RBD that has been captured by neutralizing antibodies. A strong signal from the second line indicates a high level of neutralizing antibodies in the sample. There is also a control line that detects free gold particles, confirming that the solution flowed across the entire strip.
To develop the reagents needed for the test, members of Li’s lab worked with the labs of Angela Koehler, an associate professor of biological engineering, and Michael Yaffe, a David H. Koch Professor in Science, who are both members of the Koch Institute.
Predicting immunity
Along with a testing cartridge, which contains the paper test strip, the testing kit also includes a finger prick lancet that can be used to obtain a small blood sample, less than 10 microliters. This sample is then mixed with the reagents needed for the test. After about 10 minutes, the sample is exposed to the test cartridge, and the results are revealed in 10 minutes.
The output can be read two different ways: One, by simply looking at the lines, which indicate whether neutralizing antibodies are present or not. Or, the device can be used to obtain a more precise measurement of antibody levels, using a smartphone app that can measure the intensity of each line and calculate the ratio of neutralized RBD protein to infectious RBD protein. When this ratio is low, it might suggest that another booster shot is needed, or that the individual should take extra precautions to prevent infection.
The researchers tested their device with blood samples collected in December 2020 from about 60 people who had been infected with SARS-CoV-2 and 30 people who had not. They were able to detect neutralizing antibodies in the samples from people previously infected by the virus, with accuracy similar to that of existing laboratory tests. They also tested 30 serial samples from two people before they received an mRNA Covid-19 vaccine and at several time points after vaccination. The level of neutralizing antibodies in the vaccinated individuals peaked around seven weeks after the first dose, then began to slowly decline.
Previous studies of SARS-CoV-2 and other viruses have shown a strong correlation between the amount of neutralizing antibody circulating in an individual’s bloodstream and their likelihood of infection.
The test could be easily adapted to different variants of SARS-CoV-2 by swapping in a reagent that is specific to the RBD from the variant of interest, Li says. The researchers now hope to partner with a diagnostics company that could manufacture large quantities of the tests and obtain FDA approval for their use.

Viewpoint Hosted by Dennis Quaid Brings Attention to a Little-Understood Condition Affecting Families Nationwide
A new Viewpoint hosted by Dennis Quaid segment with APFED raises awareness of eosinophilic esophagitis, its subtle symptoms, and its impact on families.
For more information, readers can visit viewpointproject.com and apfed.org.
For many families, health conditions do not always begin with a dramatic diagnosis. Sometimes they show up in small, everyday habits that seem easy to explain away. Cutting food into tiny bites. Drinking extra water with every meal. Quietly avoiding certain foods altogether. A new educational segment from Viewpoint hosted by Dennis Quaid is shining a light on those subtle warning signs through a collaboration with the American Partnership for Eosinophilic Disorders, helping more people recognize the realities of living with eosinophilic esophagitis, or EoE.
Viewpoint hosted by Dennis Quaid
The segment, distributed to Public Television stations across the country, focuses on making this chronic inflammatory condition easier for the public to understand. For viewers, that matters because EoE is often misunderstood or overlooked, even as it affects daily routines, family meals, and quality of life. By connecting medical information to real-life experiences, the program gives audiences a more human picture of what people with the condition may be facing.
When everyday habits tell a bigger story
Eosinophilic esophagitis occurs when eosinophils, a type of white blood cell, build up in the esophagus, causing inflammation that can lead to tissue damage and narrowing. But what stands out most in this story is not just the science. It is the way people often adapt without realizing it. Behaviors like chewing excessively, avoiding certain textures, or relying on liquids to help swallow can become so routine that they no longer feel unusual.
That is one reason the segment carries real community value. It encourages people to look more closely at symptoms that may have been normalized for years and to seek evaluation from specialists such as gastroenterologists or allergists. It also raises awareness among parents, caregivers, and primary care providers who may be the first to notice that something is not quite right.
More than awareness
The program also explores the emotional and social side of the condition, especially for people navigating dietary restrictions and the uncertainty of delayed diagnosis. In that sense, this is not only a story about medicine. It is also a story about advocacy, support, and the importance of helping people feel seen.
APFED Executive Director Mary Jo Strobel noted that many people with EoE do not realize they have adapted their lives around a medical condition. That message gives the segment its strongest human element: awareness can change lives, not only by leading to diagnosis, but by helping families better understand experiences that may have felt isolating or confusing.
Originally distributed in January 2025, the documentary will continue to be made available to stations through March 2027, extending its reach to more households nationwide.

Progress, Not Perfection: How Healthy Habits Can Stack Up One Step at a Time
(Feature Impact) Despite the best of intentions, it’s common for plans to build healthier habits to fall flat. Often, the culprit isn’t a lack of motivation or discipline; rather, it’s unrealistic expectations.
Overhauling your lifestyle requires a level of commitment that isn’t always practical. Understanding your personal health needs and the challenges you need to overcome can help give you a more realistic roadmap toward better health.
Tools to Guide You
Every plan needs a starting point and there are many reputable sources that can help guide you toward a plan that addresses your personal health needs.
For example, the American Heart Association introduced My Life Check, a simple, free tool to help individuals understand their heart health and what’s driving it. Users answer simple questions about their daily habits and health factors to get a personalized Heart Health Score in minutes.
The results are private and downloadable, giving you full control of your information. The tool turns big goals into small, specific actions you can start right away. Knowing your numbers relative to your heart health (and where you are in comparison to target ranges for optimal health) can help you decide how to build a better map to get you where you want to be.
While the report is customized to each individual, no personal data is stored and answers are only used to calculate health scores and provide personalized recommendations and practical steps to improve your health, so you can use your results to focus on what matters most to you. Every small step you take, such as moving more, eating smarter, sleeping better or managing stress, can add up over time.
Finding Your Path
Once you’re armed with data and know where you stand on your heart health numbers, small steps become clearer and more manageable. That knowledge makes it easier to choose one area to focus on, such as getting more sleep, taking daily walks or adding more color to your meals.
Healthy changes don’t need to be expensive or complicated. The best habits are ones that fit real life when every action you take moves you closer to your goals.
Staying motivated and on track is also easier when you can check back in, see your progress and realize the steps you’re taking are making an impact. Checking in every few months to see how you can grow gives you the chance to celebrate your progress, learn from challenges and keep building lasting habits that feel good.

Healthy Habits for Everyday Life
Eat Smart
Choose foods that help you feel your best, one meal at a time. Add more color to your plate and focus on balance, not restriction. Simple, affordable swaps can make a real difference.
Smart Tip: Aim for an overall healthy eating pattern that includes whole foods, fruits and vegetables, lean protein, nuts, seeds and cooking in non-tropical oils such as olive and canola.
Move More
Find movement that fits your life, such as a walk, a stretch or dancing while you cook. Every bit of activity counts and it all supports your heart and mind. Move for joy, not just for results.
Smart Tip:Adults should get 150 minutes of moderate physical activity (or 75 minutes of vigorous activity) per week. Kids should aim for 60 minutes every day, including play and structured activities.
Sleep Well
Rest is a foundation of good health, not a reward. Protect your bedtime routine and give your body the recovery it deserves. Notice how good sleep makes everything else easier.
Smart Tip: Most adults need 7-9 hours of sleep each night. Children require more. Adequate sleep promotes healing, improves brain function and reduces the risk for chronic diseases.
Manage Stress
Check in with yourself regularly, both mentally and emotionally. Create simple moments to pause, breathe, laugh or step outside. Connection, kindness and calm all support a healthy heart.
Smart Tip:The first step to stress management is awareness. Step “away from yourself” for a moment. Objectively ask yourself, “Is my stress level too high?” If so, look at what might be causing that stress.
Ideas for Incremental Changes
- Dedicate 15 minutes at the beginning or end of the day to focus on self-care, whether it’s unwinding with some music, writing down your goals or reflecting on the highlights of the day.
- Aim to add an extra serving of fruits or veggies each day, such as creating a savory veggie omelet or exploring new smoothie blends that let you pack in the produce on the go.
- Give your cabinets a quick update and put the smaller plates front and center. When you use a smaller plate, you can fill it while still sticking to recommended serving sizes.
- If you’re not a fan of the gym, think about how your hobbies can play a role in your physical activity. Even gardening counts as physical activity, so get creative to get moving with an activity you truly enjoy.
- Establish a bedtime routine that allows you to ease into sleep more easily. Once you feel the impact of better-quality rest, you may find yourself more motivated to make a regular bedtime a priority.

How to Practice Thoughtful Grief Etiquette Online
Grief experts advise caution in sharing condolences and loss-related information on social media, emphasizing the importance of prioritizing the grieving family’s needs. Thoughtful posting practices include waiting for family approval, reaching out privately first, and avoiding speculation about the cause of death. Compassionate communication is essential in these sensitive situations.
Last Updated on March 31, 2026 by Daily News Staff
(Feature Impact) News of a death can spread online in seconds – often before families have notified close family members privately. That’s why grief experts urge people to rethink how they share condolences, tributes and loss-related information on social media, particularly during the winter months when grief can feel especially isolating.
“Grief etiquette is about putting the needs of the grieving family first, not our urge to say something publicly,” said Dr. Camelia L. Clarke, National Funeral Directors Association (NFDA) spokesperson, funeral director and grief educator with nearly 30 years of experience. “Just because information can be shared instantly doesn’t mean it should be.”
Social media has become a common place for sharing condolences, tributes and memories. However, grief experts caution that, without thoughtful consideration, online posts can unintentionally cause harm. Knowing when to post, what to say and when to remain silent can make a meaningful difference for families experiencing loss.
Consider this advice from the experts at the NFDA.
Grief Etiquette in the Digital Age
Grief etiquette refers to the unspoken guidelines for how individuals acknowledge death, loss and mourning, particularly online.
According to Clarke, one of the most important principles is restraint.
“When a death is shared online too quickly, families can feel exposed and overwhelmed at a moment when they’re still processing the loss themselves,” she said. “Waiting is an act of compassion.”
Best Practices for Posting About Loss Online
As social media continues to play a role in modern mourning, grief professionals encourage users to pause before posting and consider a few key guidelines:
- Let the family lead. Don’t post about a death until the immediate family has made it public.
- Ask permission. Obtain consent before sharing photos, stories or tributes.
- Reach out privately first. A direct message, call or handwritten note can be more meaningful than a public comment.
- Avoid speculation. Don’t ask about or share details regarding the cause of death.
- Offer ongoing support. Grief extends far beyond the first days or weeks after a loss.
What to Say (and Avoid)
When expressing condolences online, experts recommend simplicity, sincerity and sensitivity. Messages that acknowledge loss without attempting to explain or minimize it are often the most supportive.
Helpful phrases include:
- “I’m sorry for your loss.”
- “Thinking of you and your family.”
- “I’m here if you want to talk or need anything.”
By contrast, well-meaning cliches can unintentionally cause harm. Phrases such as “They’re in a better place” or “Everything happens for a reason” may reflect the speaker’s beliefs, but they can feel dismissive to someone grieving.
“Grieving people don’t need answers – they need presence,” Clarke said. “Listening matters more than saying the perfect thing.”
Resources for Families and Friends
As digital spaces continue to shape how people communicate during life’s most difficult moments, experts agree empathy, patience and respect remain timeless.
“Grief is deeply personal,” Clarke said. “When we slow down and lead with compassion, we honor both the person who has died and those who are left to grieve.”
