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.

Millions of mobile gamers prize stress relief over winning
Mobile Gamers Prize Stress: In the school’s car pickup line, five minutes before it starts moving. In the doctor’s office waiting room for an appointment that you’ve been heavily anticipating. In bed, just before going to sleep. In these transitional moments, many people reach for their phones — not to scroll, but to play.
Millions of mobile gamers prize stress relief over winning
(Sheeka Sanahori) In the school’s car pickup line, five minutes before it starts moving. In the doctor’s office waiting room for an appointment that you’ve been heavily anticipating. In bed, just before going to sleep. In these transitional moments, many people reach for their phones — not to scroll, but to play.
According to a June 2026 survey of more than 128,000 KashKick mobile gamers, playing a mobile game is more than a way to pass the time. Stress relief and relaxation are the top reasons respondents play, beating out entertainment and fun. As KashKick reports, for many people, this means mobile games are less a simple distraction and more a coping mechanism for the daily stress of life.
A quick reset for life’s transitional moments
Most respondents identify as women, and 60% live in households that earn less than $50,000 per year. In the ranking of their reasons for playing, stress relief and relaxation topped the list, with boredom relief, entertainment and fun close behind.
The ranking reads less like a profile of a gaming hobby and more like a profile of a coping behavior.
More than half of the respondents play games daily or multiple times a day. When they reach for a mobile game, about 53% of the time it’s for a short session—usually 30 minutes or less. Where and when people play tells its own story: 58% play in bed before going to sleep and 40% play in the bathroom. These are private, solitary moments, not the times people typically plan entertainment into their day.
Coping with stress by gaming
To understand why respondents play games for stress relief more than for fun, it helps to look at who they are. Among those surveyed, 19% say they’re unemployed or looking for work, and 60% live in lower-income households. There are likely some areas of their life where they must make every dollar stretch to cover the things they need.
The survey findings coincide with research from the American Psychological Association’s 2025 Stress in America report. According to the report, 18% of men and 22% of women under age 65 rate their stress level at eight or higher on a scale of one to 10. Although the KashKick survey didn’t measure stress, respondents are mostly women and fall within the age and income groups the APA found to carry the most stress.
The APA’s report also describes loneliness as a major strain for Americans. The KashKick survey didn’t measure feelings of isolation, but 55% prefer to play alone, and 60% rarely or never discuss their gameplay with friends or family.
Overall, the survey identifies a group of people who have found a routine, low-cost approach to cope with stress. They’re not necessarily there to get the highest score. They’re playing a mobile game to help them navigate a day that, with all of life’s to-dos and challenges, could quickly feel overwhelming.
Methodology
The KashKick Gaming Habits Survey was fielded from June 8, 2026, through Aug. 10, 2026, among KashKick members in the United States who play mobile games. The Gaming Habits Survey was available to all members on KashKick’s Surveys page post-profile completion. The survey received 128,218 total responses, with question-level response counts ranging from approximately 109,793 to 128,218 depending on attrition. All findings describe KashKick mobile gamers and should not be interpreted as representative of U.S. mobile gamers overall. Industry and stress context references publicly available data from the American Psychological Association, Statista, and Newzoo.

Pediatric Cancer Goes Beyond a Victory Bell: How Research and Innovation Improve Survivorship Rates
(Feature Impact) For every tear-jerking video found online of a child ringing a bell that signifies a cancer journey victory, there are dozens, if not more, people working behind the scenes. From leading minds in cancer research to doctors, nurses and support staff, a vast network of people and decades of medical advancements make those moments possible.
In fact, in the last 10 years, the FDA approved 10 new immunotherapies and 20 molecularly targeted therapies to treat pediatric cancers, according to the American Association for Cancer Research. Those breakthroughs – and the children they impact – come with a cost, which is why Hyundai Hope on Wheels has served as a pioneer in increasing survival rates by investing $303 million in pediatric cancer research over nearly three decades.
Those funds have supported more than 1,600 grants to 210 institutions, leading to new insights into cancer biology, clinical trials and new drug development while bringing hope at all stages of a child’s cancer journey.
However, there remains work to be accomplished. According to a survey conducted by Atomik Research on behalf of Hyundai Hope on Wheels, 46% of U.S. adults believe that a child ringing a hospital bell after cancer treatment signifies the child is cancer-free and their medical journey is largely over. The reality is more nuanced than that. In fact, more than one-third of respondents said they’re not familiar with the term cancer survivorship or they have heard the term but don’t fully understand what it means.
Many health care organizations define survivorship as beginning at the time of diagnosis and continuing through treatment and beyond. According to the American Association for Cancer Research, children who survive cancer face several long-term physical and psycho-social challenges due to their cancer and treatment, including planned surgeries, additional rounds of radiation or other forms of medical treatment to address common physical challenges stemming from chemotherapy.
Survival rates continue increasing with scientific and technological breakthroughs, up from 75% to 85% in nearly three decades, representing roughly 40,000 more children surviving their diagnoses. More than 3 in 4 U.S. adults are encouraged by that progress.
For survivors, treatment is just the beginning. Research, follow-up care and long-term funding determine what comes next, and every grant funded and every survivorship program backed means more children reaching adulthood.
According to the survey, more than 80% of adults said they’re more likely to support organizations that fund survivorship services, creating opportunities to fund crucial research and support for children facing pediatric cancer. Collaboration among leading minds, made possible by funding from organizations like Hyundai Hope on Wheels, has led to the development of comprehensive approaches to help children thrive during life after cancer, including enhanced medical records, AI integration, socioemotional support and combatting long-term side effects.

A child rings the cancer bell. Here’s what that moment doesn’t show
Cancer Bell: A child who’s been treated for cancer walks down the hall of a medical facility, nurses and doctors smiling at them from all corners of the room. The child rings a bell, and everyone cheers as the kid hugs their loved ones. These heartfelt videos appear regularly across social media. What helps make each of those moments possible is decades of research and innovation. For every bell-ringing child whose video goes viral online, a longer health journey awaits.

(Sheeka Sanahon) A child who’s been treated for cancer walks down the hall of a medical facility, nurses and doctors smiling at them from all corners of the room. The child rings a bell, and everyone cheers as the kid hugs their loved ones. These heartfelt videos appear regularly across social media. What helps make each of those moments possible is decades of research and innovation. In the last 10 years, the Food and Drug Administration (FDA) approved 10 new immunotherapies and 20 molecularly targeted therapies to treat pediatric cancers, according to the American Association for Cancer Research.
For every bell-ringing child whose video goes viral online, a longer health journey awaits. Hyundai Hope on Wheels, which has funded pediatric cancer research for nearly three decades, commissioned a survey to understand how much Americans know about that journey.
As September marks Childhood Cancer Awareness Month, what that journey actually looks like is worth understanding. According to the survey, 46% of U.S. adults believe that a child ringing a hospital bell after cancer treatment signifies the child is cancer-free and their medical journey is largely over. The reality is more nuanced than that.
When cancer survivorship begins
Many health care organizations define survivorship as beginning at the time of diagnosis and continuing through treatment and beyond. Understanding survivorship this way helps recognize that a child’s cancer journey is about more than reaching the end of treatment. It also includes managing long-term physical, emotional and medical needs that may continue for years to come.
More than a third of U.S. adults say they’re not familiar with the term cancer survivorship or they have heard theterm but don’t fully understand what it means.
According to the American Association for Cancer Research, children who survive cancer face several long-term physical and psycho-social challenges due to their cancer and treatment. Children could face planned surgeries, additional rounds of radiation, or other forms of medical treatment to address common physical challenges stemming from chemotherapy. Every child’s medical treatment plan is different based on their specific needs, but one thing is clear: Pediatric cancer survivors need ongoing support as they navigate long-term health challenges.
Supporting children to live long, full lives
More than 3 in 4 U.S. adults are encouraged by the progress in pediatric cancer, up 5 points from last year. There’s good reason to be hopeful, too. According to the American Cancer Society, the survival rate among pediatric cancer patients has increased from 75% to 85% in nearly three decades, representing 40,000 more children surviving their cancer diagnosis.
Survival rates continue to increase thanks to breakthrough science and technology, and higher standards of care. Pediatric cancer research has led to new insights into cancer biology, clinical trials, and new drug development.
More than 8 in 10 adults say they’re more likely to support organizations that fund survivorship services, which creates more opportunities to fund crucial research and support for children facing pediatric cancer.
Methodology
Hyundai Hope on Wheels commissioned Atomik Research to conduct an online survey of 1,005 adults throughout the United States. The margin of error is +/- 3 percentage points with a confidence level of 95%. Fieldwork took place March 19-26, 2026. Atomik Research, part of 4media group, is a creative market research agency.
