How the stress of playing chess can be fatal

The death of a chess player in the middle of a match at the world’s most prestigious competition may have shocked those who view the game as a relaxing pastime. Kurt Meier, 67, collapsed during his final match in the tournament and died in hospital later that day. But chess, like any other game or sport, can lead to an immense amount of stress, which can be bad for a competitor’s physical health too.

We tend to associate playing sport or games with good health and well-being. And there are a countless number of studies showing playing games has an association with feeling happier. While this argument is true for recreational players, the story can be different for the elite, where success and failure are won and lost by the finest margins and where winning can mean funding and a future, and losing can mean poverty and unemployment. If this is the case, can being successful at a sport or game actually be bad for you?

Competitive anxiety

Elite competition can be stressful because the outcome is so important to the competitors. We can measure stress using a whole range of physiological indicators such as heart rate and temperature, and responses such as changes in the intensity of our emotions.

Emotions provide a warning of threat. So if you feel that achieving your goal is going to be difficult, then expect to feel intense emotions. The leading candidate that signals we are experiencing stress is anxiety, characterised by thoughts of worry, fears of dread about performance, along with accompanying physiological responses such as increased heart rate and sweaty palms. If these symptoms are experienced regularly or chronically, then this is clearly detrimental to health.

This stress response is probably not restricted to elite athletes. Intense emotions are linked to trying to achieve important goals and while it isn’t the only situation where it occurs, it is just very noticeable in sport.

The causes of stress

It makes more sense to focus on what the causes of stress are rather than where we experience it. The principle is that the more important the goal is to achieve, then the greater the propensity for the situation to intensify emotions.

Emotions intensify also by the degree of uncertainty and competing, at whatever level of a sport, is uncertain when the opposition is trying its hardest to win the contest and also has a motivation to succeed. The key point is that almost all athletes at any level can suffer bouts of stress, partly due to high levels of motivation.

A stress response is also linked to how performance is judged and reported. Potentially stressful tasks tend to be ones where performance is public and feedback is immediate. In chess – as with most sporting contests – we see who the winner is and can start celebrating success or commiserating failure as soon as the game is over.

There are many tasks which have similar features. Giving a speech in public, taking an academic examination, or taking your driving test are all examples of tasks that can illicit stress. Stress is not restricted to formal tasks but can also include social tasks. Asking a potential partner for a date, hand in marriage, and meeting the in-laws for the first time can be equally stressful.

Winning a contest or going on a date relate to higher-order goals about how we see ourselves. If we define ourselves as “being a good player” or “being attractive or likeable” then contrasting information is likely to associate with unpleasant emotions. You will feel devastated if you are turned down when asking someone out on a date, for instance, and if this was repeated, it could lead to reduced self-esteem and depression.

The key message here is to recognise what your goals are and think about how important they are. If you want to achieve them with a passion and if the act of achieving them leads to intense and sometimes unwanted emotions, then it’s worth thinking about doing some work to manage these emotions.

  • 5 Ways To Beat Cancer (And Other Diseases)

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    A Systematic Approach To Healthy Eating

    Dr. William Li, known for ways to beat cancer and other diseases, in front of a blue background.

    This is Dr. William Li. He’s a physician, cancer researcher, and educator. He also founded the Angiogenesis Foundation back in 1994.

    We recently reviewed one of his books, “Eat To Beat Disease”.

    He has another book that we haven’t reviewed at time of writing, “Eat To Beat Your Diet“, which you might like to check out.

    What does he want us to know?

    He wants us to know how to eat to beat cancer and other diseases, by means of five specific angles:

    Angiogenesis

    This is about replacing blood vessels, which of course happens all the time, but it becomes a problem when it is feeding a cancer in the process.

    Here, based on Dr. Li’s work, is what can be done about it:

    A List of Anti-Angiogenic Foods for a Cancer-Fighting Diet

    Regeneration

    Generally speaking, we want to replace healthy cells early, because if we wait until they get damaged, then that damage will be copied forwards. As well as intermittent fasting, there are other things we can do to promote this—even, Dr. Li’s research shows, for stem cells:

    Doctor’s Tip: Regeneration (stem cells)—one of your body’s five defense systems

    Microbiome health

    Healthy gut, healthy rest of the body. We’ve written about this before:

    Making Friends With Your Gut (You Can Thank Us Later)

    DNA protection

    DNA gets unravelled and damaged with age, the telomere caps get shorter, and mistakes get copied forward. So there more we can protect our DNA, the longer we can live healthily. There are many ways to do this, but Dr. Li was one of the first to bring to light the DNA-protecting benefits of kiwi fruit:

    Kiwi: A Darling for DNA

    Immunity

    Paradoxically, what’s good for your immune system (making it stronger) also helps to protect against autoimmune diseases (for most people, for the most part).

    In short: it’s good to have an immune system that’s powerful not just in its counterattacks, but also in its discerning nature. There are dietary and other lifestyle approaches to both, and they’re mostly the same things:

  • You can now order all kinds of medical tests online. Our research shows this is (mostly) a bad idea

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Many of us have done countless rapid antigen tests (RATs) over the course of the pandemic. Testing ourselves at home has become second nature.

    But there’s also a growing worldwide market in medical tests sold online directly to the public. These are “direct-to-consumer” tests, and you can access them without seeing a doctor.

    While this might sound convenient, the benefits to most consumers are questionable, as we discovered in a recent study.

    What are direct-to-consumer tests?

    Let’s start with what they’re not. We’re not talking about patients who are diagnosed with a condition, and use tests to monitor themselves (for example, finger-prick testing to monitor blood sugar levels for people with diabetes).

    We’re also not talking about home testing kits used for population screening, such as RATs for COVID, or the “poo tests” sent to people aged 50 and over for bowel cancer screening.

    Direct-to-consumer tests are products marketed to anyone who is willing to pay, without going through their GP. They can include hormone profiling tests, tests for thyroid disease and food sensitivity tests, among many others.

    Some direct-to-consumer tests allow you to complete the test at home, while self-collected lab tests give you the equipment to collect a sample, which you then send to a lab. You can now also buy pathology requests for a lab directly from a company without seeing a doctor.

    What we did in our study

    We searched (via Google) for direct-to-consumer products advertised for sale online in Australia between June and December 2021. We then assessed whether each test was likely to provide benefits to those who use them based on scientific literature published about the tests, and any recommendations either for or against their use from professional medical organisations.

    We identified 103 types of tests and 484 individual products ranging in price from A$12.99 to A$1,947.

    We concluded only 11% of these tests were likely to benefit most consumers. These included tests for STIs, where social stigma can sometimes discourage people from testing at a clinic.

    A further 31% could possibly benefit a person, if they were at higher risk. For example, if a person had symptoms of thyroid disease, a test may benefit them. But the Royal Australian College of General Practitioners does not recommend testing for thyroid disease in people without symptoms because evidence showing benefits of identifying and treating people with early thyroid disease is lacking.

    Some 42% were commercial “health checks” such as hormone and nutritional status tests. Although these are legitimate tests – they may be ordered by a doctor in certain circumstances, or be used in research – they have limited usefulness for consumers.

    A test of your hormone or vitamin levels at a particular time can’t do much to help you improve your health, especially because test results change depending on the time of day, month or season you test.

    Most worryingly, 17% of the tests were outright “quackery” that wouldn’t be recommended by any mainstream health practitioner. For example, hair analysis for assessing food allergies is unproven and can lead to misdiagnosis and ineffective treatments.

    More than half of the tests we looked at didn’t state they offered a pre- or post-test consultation.

    Ordering medical tests online probably isn’t a good idea.

    Products available may change outside the time frame of our study, and direct-to-consumer tests not promoted or directly purchasable online, such as those offered in pharmacies or by commercial health clinics, were not included.

    But in Australia, ours is the first and only study we know of mapping the scale and variety of direct-to-consumer tests sold online.

    Research from other countries has similarly found a lack of evidence to support the majority of direct-to-consumer tests.

    4 questions to ask before you buy a test online

    Many direct-to-consumer tests offer limited benefits, and could even lead to harms. Here are four questions you should ask yourself if you’re considering buying a medical test online.

    1. If I do this test, could I end up with extra medical appointments or treatments I don’t need?

    Doing a test yourself might seem harmless (it’s just information, after all), but unnecessary tests often find issues that would never have caused you problems.

    For example, someone taking a diabetes test may find moderately high blood sugar levels see them labelled as “pre-diabetic”. However, this diagnosis has been controversial, regarded by many as making patients out of healthy people, a large number of whom won’t go on to develop diabetes.

    2. Would my GP recommend this test?

    If you have worrying symptoms or risk factors, your GP can recommend the best tests for you. Tests your GP orders are more likely to be covered by Medicare, so will cost you a lot less than a direct-to-consumer test.

    3. Is this a good quality test?

    A good quality home self-testing kit should indicate high sensitivity (the proportion of true cases that will be accurately detected) and high specificity (the proportion of people who don’t have the disease who will be accurately ruled out). These figures should ideally be in the high 90s, and clearly printed on the product packaging.

    For tests analysed in a lab, check if the lab is accredited by the National Association of Testing Authorities. Avoid tests sent to overseas labs, where Australian regulators can’t control the quality, or the protection of your sample or personal health information.

    4. Do I really need this test?

    There are lots of reasons to want information from a test, like peace of mind, or just curiosity. But unless you have clear symptoms and risk factors, you’re probably testing yourself unnecessarily and wasting your money.

    Direct-to-consumer tests might seem like a good idea, but in most cases, you’d be better off letting sleeping dogs lie if you feel well, or going to your GP if you have concerns.The Conversation

  • How to keep your teeth young

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    How to keep your teeth young

    The association between aging and teeth is so well-established that it’s entered popular idiom, “too long in the tooth”, and when it comes to visual representations, false teeth are well-associated with old age.

    And yet, avoiding such outcomes does not get anywhere near so much attention as, say, avoiding wrinkles or hair loss.

    At 10almonds, we’ve covered general dental health before, in a three-part series:

    1. Toothpastes & Mouthwashes: Which Help And Which Harm?
    2. Flossing, Better (And Easier!)
    3. Less Common Oral Hygiene Options

    Today, we’re going to be looking specifically at keeping our teeth young. What if you have lost your teeth already? Well, gum health remains important, and it’s foundational for everyone, so…

    Look after your gums first and last

    Hollywood’s most “perfect” whites would be nothing without the gums holding them in place. So, set aside the cosmetic whitening products that often harm gums (anything containing bleach / hydrogen peroxide, is generally a bad idea), andinstead focus on your gums.

    As for avoiding gum disease (periodontitis)?

    ❝In conclusion, periodontitis might enhance the association of biological aging with all-cause mortality in middle-aged and older adults.

    Hence, maintaining and enhancing periodontal health is expected to become an intervention to slow aging and extend life span.❞

    Source: Does Periodontitis Affect the Association of Biological Aging with Mortality?

    Ways to look after gum health include the obvious “floss” and “brush often” and “use fluoride toothpaste”, along with other options we covered in our “Less Common Oral Hygiene Options” article above.

    Also important: don’t smoke. It is bad for everything, and this is no exception.

    We expect we probably don’t have many subscribers who smoke, but if you do, please consider making quitting a priority.

    See also: Smoking, Gum Disease, and Tooth Loss

    Consider supplementing with collagen

    Everyone’s all about the calcium and vitamin D for bones (and teeth), but a large part of the mass of both is actually collagen. And unlike calcium, which most people not living in a food desert get plenty of, or vitamin D, which is one of the most popular supplements around, collagen is something that gets depleted as we get older. We’ve written about its importance for bones:

    We Are Such Stuff As Fish Are Made Of—Collagen’s benefits are more than skin deep

    And as for its role in combatting gum disease and tooth loss:

    Nanoscale Dynamics of Streptococcal Adhesion to AGE-Modified Collagen

    By the way, that “AGE” there isn’t about chronological age; it’s about advanced glycation end-products. Those are also something you can and should avoid:

    Are You Eating AGEs?

    A different kind of “spit and polish”

    We imagine you have the “polishing” part in hand; that’s tooth-brushing, of course. But spit?

    Saliva is hugely important for our oral health, but it’s not something most of us think about a lot. For example, you might not have known (or might have known but not thought much about) that many common medications affect our saliva, including many blood pressure medications and antidepressants:

    Impact of ageing and drug consumption on oral health

    Because there are so many possibilities, this is the kind of thing to check with your pharmacist or doctor about. But as a rule, if you take a medication whose side-effects include “dry mouth”, this might be you.

    Here’s a really useful (academic) article that covers what drugs cause this, how to diagnose it, and what can be done about it:

    Hyposalivation in Elderly Patients

    If something’s difficult, find a way to make it easier

    Sometimes, as we get older, some things that used to be easy, aren’t. We can lose strength, coordination, manual dexterity, memory, attention, and more. Obviously, we try not to, and do what we can to keep ourselves in good health.

    But, if you do have some disability that makes for example brushing and/or flossing difficult to do consistently and/or well, consider talking to your doctor to see if there are assistive devices that can help, or some other kind of support that could allow you to do what you need to.

    See also: Improving oral hygiene for better cognitive health: Interrelationships of oral hygiene habits, oral health status, and cognitive function in older adults

    There’s never any shame in getting help if we need it.

    Take care!

  • Healthiest-Three-Nut Butter

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    We’re often telling you to “diversify your nuts”, so here’s a great way to get in three at once with no added sugar, palm oil, or preservatives, and only the salt you choose to put in. We’ve picked three of the healthiest nuts around, but if you happen to be allergic, don’t worry, we’ve got you covered too.

    You will need

    • 1 cup almonds (if allergic, substitute a seed, e.g. chia, and make it ½ cup)
    • 1 cup walnuts (if allergic, substitute a seed, e.g. pumpkin, and make it ½ cup)
    • 1 cup pistachios (if allergic, substitute a seed, e.g. poppy, and make it ½ cup)
    • 1 tbsp almond oil (if allergic, substitute extra virgin olive oil) (if you prefer sweet nut butter, substitute 1 tbsp maple syrup; the role here is to emulsify the nuts, and this will do the same job)
    • Optional: ¼ tsp MSG or ½ tsp low-sodium salt

    Method

    (we suggest you read everything at least once before doing anything)

    1a) If using nuts, heat your oven to 350℉ / 180℃. Place the nuts on a baking tray lined with baking paper, and bake/roast for about 10 minutes, but keep an eye on it to ensure the nuts don’t burn, and jiggle them if necessary to ensure they toast evenly. Once done, allow to cool.

    1b) If using seeds, you can either omit that step, or do the same for 5 minutes if you want to, but really it’s not necessary.

    2) Blend all ingredients (nuts/seeds, oil, MSG/salt) in a high-speed blender. Note: this will take about 10 minutes in total, and we recommend you do it in 30-second bursts so as to not overheat the motor. You also may need to periodically scrape the mixture down the side of the blender, to ensure a smooth consistency.

    3) Transfer to a clean jar, and enjoy at your leisure:

  • Mosquitoes can spread the flesh-eating Buruli ulcer. Here’s how you can protect yourself

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Each year, more and more Victorians become sick with a flesh-eating bacteria known as Buruli ulcer. Last year, 363 people presented with the infection, the highest number since 2004.

    But it has been unclear exactly how it spreads, until now. New research shows mosquitoes are infected from biting possums that carry the bacteria. Mozzies spread it to humans through their bite.

    What is Buruli ulcer?

    Buruli ulcer, also known as Bairnsdale ulcer, is a skin infection caused by the bacterium Mycobacterium ulcerans.

    It starts off like a small mosquito bite and over many months, slowly develops into an ulcer, with extensive destruction of the underlying tissue.

    While often painless initially, the infection can become very serious. If left untreated, the ulcer can continue to enlarge. This is where it gets its “flesh-eating” name.

    Thankfully, it’s treatable. A six to eight week course of specific antibiotics is an effective treatment, sometimes supported with surgery to remove the infected tissue.

    Where can you catch it?

    The World Health Organization considers Buruli ulcer a neglected tropical skin disease. Cases have been reported across 33 countries, primarily in west and central Africa.

    However, since the early 2000s, Buruli ulcer has also been increasingly recorded in coastal Victoria, including suburbs around Melbourne and Geelong.

    Scientists have long known Australian native possums were partly responsible for its spread, and suspected mosquitoes also played a role in the increase in cases. New research confirms this.

    Our efforts to ‘beat Buruli’

    Confirming the role of insects in outbreaks of an infectious disease is achieved by building up corroborating, independent evidence.

    In this new research, published in Nature Microbiology, the team (including co-authors Tim Stinear, Stacey Lynch and Peter Mee) conducted extensive surveys across a 350 km² area of Victoria.

    We collected mosquitoes and analysed the specimens to determine whether they were carrying the pathogen, and links to infected possums and people. It was like contact tracing for mosquitoes.

    Aedes notoscriptus was the mosquito identified as carrying the bacteria that caused Buruli ulcer.
    Cameron Webb (NSW Health Pathology)

    Molecular testing of the mosquito specimens showed that of the two most abundant mosquito species, only Aedes notoscriptus (a widespread species commonly known as the Australian backyard mosquito) was positive for Mycobacterium ulcerans.

    We then used genomic tests to show the bacteria found on these mosquitoes matched the bacteria in possum poo and humans with Buruli ulcer.

    We further analysed mosquito specimens that contained blood to show Aedes notoscriptus was feeding on both possums and humans.

    To then link everything together, geospatial analysis revealed the areas where human Buruli ulcer cases occur overlap with areas where both mosquitoes and possums that harbour Mycobacterium ulcerans are active.

    Stop its spread by stopping mozzies breeding

    The mosquito in this study primarily responsible for the bacteria’s spread is Aedes notoscriptus, a mosquito that lays its eggs around water in containers in backyard habitats.

    Controlling “backyard” mosquitoes is a critical part of reducing the risk of many global mosquito-borne disease, especially dengue and now Buruli ulcer.

    You can reduce places where water collects after rainfall, such as potted plant saucers, blocked gutters and drains, unscreened rainwater tanks, and a wide range of plastic buckets and other containers. These should all be either emptied at least weekly or, better yet, thrown away or placed under cover.

    Mosquitoes can lay eggs in a wide range of water-filled items in the backyard.
    Cameron Webb (NSW Health Pathology)

    There is a role for insecticides too. While residual insecticides applied to surfaces around the house and garden will reduce mosquito populations, they can also impact other, beneficial, insects. Judicious use of such sprays is recommended. But there are ecological safe insecticides that can be applied to water-filled containers (such as ornamental ponds, fountains, stormwater pits and so on).

    Recent research also indicates new mosquito-control approaches that use mosquitoes themselves to spread insecticides may soon be available.

    How to protect yourself from bites

    The first line of defence will remain personal protection measures against mosquito bites.

    Covering up with loose fitted long sleeved shirts, long pants, and covered shoes will provide physical protection from mosquitoes.

    Applying topical insect repellent to all exposed areas of skin has been proven to provide safe and effective protection from mosquito bites. Repellents should include diethytolumide (DEET), picaridin or oil of lemon eucalyptus.

    While the rise in Buruli ulcer is a significant health concern, so too are many other mosquito-borne diseases. The steps to avoid mosquito bites and exposure to Mycobacteriam ulcerans will also protect against viruses such as Ross River, Barmah Forest, Japanese encephalitis, and Murray Valley encephalitis.The Conversation

  • The Path to a Better Tuberculosis Vaccine Runs Through Montana

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    A team of Montana researchers is playing a key role in the development of a more effective vaccine against tuberculosis, an infectious disease that has killed more people than any other.

    The BCG (Bacille Calmette-Guérin) vaccine, created in 1921, remains the sole TB vaccine. While it is 40% to 80% effective in young children, its efficacy is very low in adolescents and adults, leading to a worldwide push to create a more powerful vaccine.

    One effort is underway at the University of Montana Center for Translational Medicine. The center specializes in improving and creating vaccines by adding what are called novel adjuvants. An adjuvant is a substance included in the vaccine, such as fat molecules or aluminum salts, that enhances the immune response, and novel adjuvants are those that have not yet been used in humans. Scientists are finding that adjuvants make for stronger, more precise, and more durable immunity than antigens, which create antibodies, would alone.

    Eliciting specific responses from the immune system and deepening and broadening the response with adjuvants is known as precision vaccination. “It’s not one-size-fits-all,” said Ofer Levy, a professor of pediatrics at Harvard University and the head of the Precision Vaccines Program at Boston Children’s Hospital. “A vaccine might work differently in a newborn versus an older adult and a middle-aged person.”

    The ultimate precision vaccine, said Levy, would be lifelong protection from a disease with one jab. “A single-shot protection against influenza or a single-shot protection against covid, that would be the holy grail,” Levy said.

    Jay Evans, the director of the University of Montana center and the chief scientific and strategy officer and a co-founder of Inimmune, a privately held biotechnology company in Missoula, said his team has been working on a TB vaccine for 15 years. The private-public partnership is developing vaccines and trying to improve existing vaccines, and he said it’s still five years off before the TB vaccine might be distributed widely.

    It has not gone unnoticed at the center that this state-of-the-art vaccine research and production is located in a state that passed one of the nation’s most extreme anti-vaccination laws during the pandemic in 2021. The law prohibits businesses and governments from discriminating against people who aren’t vaccinated against covid-19 or other diseases, effectively banning both public and private employers from requiring workers to get vaccinated against covid or any other disease. A federal judge later ruled that the law cannot be enforced in health care settings, such as hospitals and doctors’ offices.

    In mid-March, the Bill & Melinda Gates Medical Research Institute announced it had begun the third and final phase of clinical trials for the new vaccine in seven countries. The trials should take about five years to complete. Research and production are being done in several places, including at a manufacturing facility in Hamilton owned by GSK, a giant pharmaceutical company.

    Known as the forgotten pandemic, TB kills up to 1.6 million people a year, mostly in impoverished areas in Asia and Africa, despite its being both preventable and treatable. The U.S. has seen an increase in tuberculosis over the past decade, especially with the influx of migrants, and the number of cases rose by 16% from 2022 to 2023. Tuberculosis is the leading cause of death among people living with HIV, whose risk of contracting a TB infection is 20 times as great as people without HIV.

    “TB is a complex pathogen that has been with human beings for ages,” said Alemnew Dagnew, who heads the program for the new vaccine for the Gates Medical Research Institute. “Because it has been with human beings for many years, it has evolved and has a mechanism to escape the immune system. And the immunology of TB is not fully understood.”

    The University of Montana Center for Translational Medicine and Inimmune together have 80 employees who specialize in researching a range of adjuvants to understand the specifics of immune responses to different substances. “You have to tailor it like tools in a toolbox towards the pathogen you are vaccinating against,” Evans said. “We have a whole library of adjuvant molecules and formulations.”

    Vaccines are made more precise largely by using adjuvants. There are three basic types of natural adjuvants: aluminum salts; squalene, which is made from shark liver; and some kinds of saponins, which are fat molecules. It’s not fully understood how they stimulate the immune system. The center in Missoula has also created and patented a synthetic adjuvant, UM-1098, that drives a specific type of immune response and will be added to new vaccines.

    One of the most promising molecules being used to juice up the immune system response to vaccines is a saponin molecule from the bark of the quillay tree, gathered in Chile from trees at least 10 years old. Such molecules were used by Novavax in its covid vaccine and by GSK in its widely used shingles vaccine, Shingrix. These molecules are also a key component in the new tuberculosis vaccine, known as the M72 vaccine.

    But there is room for improvement.

    “The vaccine shows 50% efficacy, which doesn’t sound like much, but basically there is no effective vaccine currently, so 50% is better than what’s out there,” Evans said. “We’re looking to take what we learned from that vaccine development with additional adjuvants to try and make it even better and move 50% to 80% or more.”

    By contrast, measles vaccines are 95% effective.

    According to Medscape, around 15 vaccine candidates are being developed to replace the BCG vaccine, and three of them are in phase 3 clinical trials.

    One approach Evans’ center is researching to improve the new vaccine’s efficacy is taking a piece of the bacterium that causes TB, synthesizing it, and combining it with the adjuvant QS-21, made from the quillay tree. “It stimulates the immune system in a way that is specific to TB and it drives an immune response that is even closer to what we get from natural infections,” Evans said.

    The University of Montana center is researching the treatment of several problems not commonly thought of as treatable with vaccines. They are entering the first phase of clinical trials for a vaccine for allergies, for instance, and first-phase trials for a cancer vaccine. And later this year, clinical trials will begin for vaccines to block the effects of opioids like heroin and fentanyl. The University of Montana received the largest grant in its history, $33 million, for anti-opioid vaccine research. It works by creating an antibody that binds with the drug in the bloodstream, which keeps it from entering the brain and creating the high.

    For now, though, the eyes of health care experts around the world are on the trials for the new TB vaccines, which, if they are successful, could help save countless lives in the world’s poorest places.
