We know vaccines have been a miracle for public health. Now, new research led by the World Health Organization has found vaccines have saved an estimated 154 million lives in the past 50 years from 14 different diseases. Most of these have been children under five, and around two-thirds children under one year old.
In 1974 the World Health Assembly launched the Expanded Programme on Immunization with the goal to vaccinate all children against diphtheria, tetanus, pertussis (whooping cough), measles, polio, tuberculosis and smallpox by 1990. The program was subsequently expanded to include several other diseases.
The modelling, marking 50 years since this program was established, shows a child aged under ten has about a 40% greater chance of living until their next birthday, compared to if we didn’t have vaccines. And these positive effects can be seen well into adult life. A 50-year-old has a 16% greater chance of celebrating their next birthday thanks to vaccines.
What the study did
The researchers developed mathematical and statistical models which took in vaccine coverage data and population numbers from 194 countries for the years 1974–2024. Not all diseases were included (for example smallpox, which was eradicated in 1980, was left out).
The analysis includes vaccines for 14 diseases, with 11 of these included in the Expanded Programme on Immunization. For some countries, additional vaccines such as Japanese encephalitis, meningitis A and yellow fever were included, as these diseases contribute to major disease burden in certain settings.
The models were used to simulate how diseases would have spread from 1974 to now, as vaccines were introduced, for each country and age group, incorporating data on increasing vaccine coverage over time.
Children are the greatest beneficiaries of vaccines
Since 1974, the rates of deaths in children before their first birthday has more than halved. The researchers calculated almost 40% of this reduction is due to vaccines.
The effects have been greatest for children born in the 1980s because of the intensive efforts made globally to reduce the burden of diseases like measles, polio and whooping cough.
Some 60% of the 154 million lives saved would have been lives lost to measles. This is likely due to its ability to spread rapidly. One person with measles can spread the infection to 12–18 people.
The study also found some variation across different parts of the world. For example, vaccination programs have had a much greater impact on the probability of children living longer across low- and middle-income countries and settings with weaker health systems such as the eastern Mediterranean and African regions. These results highlight the important role vaccines play in promoting health equity.
Vaccine success is not assured
Low or declining vaccine coverage can lead to epidemics which can devastate communities and overwhelm health systems.
Notably, the COVID pandemic saw an overall decline in measles vaccine coverage, with 86% of children having received their first dose in 2019 to 83% in 2022. This is concerning because very high levels of vaccination coverage (more than 95%) are required to achieve herd immunity against measles.
In Australia, the coverage for childhood vaccines, including measles, mumps and rubella, has declined compared to before the pandemic.
This study is a reminder of why we need to continue to vaccinate – not just against measles, but against all diseases we have safe and effective vaccines for.
The results of this research don’t tell us the full story about the impact of vaccines. For example, the authors didn’t include data for some vaccines such as COVID and HPV (human papillomavirus). Also, like with all modelling studies, there are some uncertainties, as data was not available for all time periods and countries.
Nonetheless, the results show the success of global vaccination programs over time. If we want to continue to see lives saved, we need to keep investing in vaccination locally, regionally and globally.

Are You Flourishing? (There’s a Scale)
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.
What does it mean, to flourish? And how can you do it more?
In 2009, psychologists Diener et al developed the “Flourishing Scale”, or as it was more prosaically called originally, “Subjective Wellness Scale”. The name was changed later, as it was noted that it went beyond what was typically considered mere “wellness”.
This scale was so useful, that colleagues scrambled to see if they could improve on it, such as with PERMA (2012), which looked at:
- Positive emotion
- Engagement
- positive Relationships
- Meaning
- Accomplishment/Achievement
While popular (despite the tenuous acronym, it is a very good list of things to foster in your life), this was studied and measured scientifically and found to not be an improvement on the Flourishing Scale / SWS, so we’re going to stick to the original version for now.
We couldn’t find an interactive online quiz for the scale though (apart from this NY Times one, which is paywalled for NYT subscribers, so enjoy if you’re a NYT subscriber!), so here’s the source material, still hosted on the website of the (now deceased, as of a couple of years ago) author:
Flourishing Scale (FS) ← it’s an eight-question, ranked choice scale
How did you score? And…
What are the keys to flourishing more?
According to Jeffrey Davis M.A., of Tracking Wonder, there are five key attributes that we must develop and/or maintain:
The ability to direct and re-direct your attention
This isn’t just a task-related thing.This is about your mind itself. For example, the ability to recognize what your emotions are telling you, thank them for the message, and then set them aside. Or the ability to cut through negative thought spirals! How often have you worried about future events that didn’t transpire, or twisted yourself in knots over a past event that you can’t change?
Action: check out our previous article “The Off-Button For Your Brain” ← this is a technique for switching off racing thoughts, and it’s really good
Want more? We also did this:
The tendency to shape your time with intention and for impact
Time is an incredibly precious asset. How you use it is a very personal choice. You don’t have to maximize productivity (though you can if you want), but for example there’s a difference between:
- Deciding to spend an hour watching a TV show you really enjoy
- Wondering what’s on TV, browsing aimlessly, watching listlessly, just a distraction
In the former case, you are enjoying your time. Literally: you are experiencing joy during your time.
In the latter case, to borrow from Jim Steinman, “you were only killing time and it’ll kill you right back”!
Action: do a time audit for a week, and see where your time really goes, rather than where you expect or hope for it to go. Use this information to plan your next week more intentionally. Repeat as and when it seems like it might be useful!
The practice of constant improvement
Fun fact: you are good enough already. And you can also improve. You don’t have to, but improving in the areas that are meaningful to you can really add up over time. This could be becoming excellent at something for which already have a passion… It could also be brushing up something that you feel might be holding you back.
Action: do a quick SWOT* self-assessment. Then plan your next step from there!
*Strengths, Weaknesses, Opportunities, Threats. What are yours?
The ability to communicate and listen to others
A lot of this is about feedback. Giving and receiving feedback are often amongst the hardest things we do in the category of communication… Especially if the feedback is negative. How to decide what to disregard as baseless criticism, and what to take on board (and try not to take it personally), or the other way around, how to present negative feedback in a way that won’t trigger defensiveness.
Action: check out our previous article “Save Time With Better Communication” for some tips that really make relationships (of any kind) so much easier.
The commitment to positive experiences
Many things in life are not fun. Often, we know in advance that they will not be fun. The key here is the ability to make the most of a bad situation, and seek out better situations by your actions. Not like a lost person in a desert seeks water, but like a chess player who employs a general strategy to make tactical advantages more likely to appear.
Action: think about something you have to do but don’t want to. How could it be made more fun? Or failing that, how could it be made at least more comfortable?

Creatine’s Brain Benefits Increase With Age
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.
Creatine is generally thought of as a body-building supplement, and for most young people, that’s all it is. But with extra years come extra advantages, and creatine starts to confer cognitive benefits. Dr. Brad Stanfield shares the science:
What the science says
Although 95% of creatine is stored in muscles, 5% is found in the brain, where it helps produce energy needed for brain processes (and that’s a lot of energy—about 20% of our body’s metabolic base rate is accounted for by our brain).
In this video, Dr. Stanfield shares studies showing creatine improving memory, especially in older adults—and also in vegetarians/vegans, since creatine is found in meat (just like in our own bodies, which are also made of meat) and not in plants. On the meta-analysis level, a systematic review concluded that creatine supplementation indeed improves memory, with stronger effects observed in older adults.
Dr. Stanfield also addresses the safety concerns about creatine, which, on balance, are not actually supported by the science (of course, always consult your own doctor to be sure, as your case could vary).
As for dosage, 5g/day is recommended. For more on all of this plus links to the studies cited, enjoy:

Metabolism Made Simple – by Sam Miller
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.
The author, a nutritionist, sets out to present exactly what the title promises: metabolism made simple.
On this, he delivers. Explaining things from the most basic elements upwards, he gives a well-rounded introduction to the science of metabolism and what it means for us when it comes to our dietary habits.
The book is in large part a how-to, but with a lot of flexibility left to the reader. He doesn’t advocate for any particular dietary plan, but he does give the reader the tools necessary to make an informed choice and go from there—including the pros and cons of some popular dietary approaches.
He talks a lot about getting the most out of whatever we do choose to—managing appetite, mitigating adaptation, maximizing adherence, optimizing absorption of nutrients, and so forth.
The book does also touch on things like exercise and stress management, but diet is always center-stage and is the main topic of the book.
The style is—as promised by the title—simple. However, this simply means that he avoids unnecessary jargon and explains any necessary terms along the way. As for backing up claims with science, there are 22 pages of references, which is always a good sign.
Bottom line: if you’d like a simple, practical guide to eating for metabolic health, this book will start you off on a good footing.

How stigma perpetuates substance use
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.
In 2022, 54.6 million people 12 and older in the United States needed substance use disorder (SUD) treatment. Of those, only 24 percent received treatment, according to the most recent National Survey on Drug Use and Health.
SUD is a treatable, chronic medical condition that causes people to have difficulty controlling their use of legal or illegal substances, such as alcohol, tobacco, prescription opioids, heroin, methamphetamine, or cocaine. Using these substances may impact people’s health and ability to function in their daily life.
While help is available for people with SUD, the stigma they face—negative attitudes, stereotypes, and discrimination—often leads to shame, worsens their condition, and keeps them from seeking help.
Read on to find out more about how stigma perpetuates substance use.
Stigma can keep people from seeking treatment
Suzan M. Walters, assistant professor at New York University’s Grossman School of Medicine, has seen this firsthand in her research on stigma and health disparities.
She explains that people with SUD may be treated differently at a hospital or another health care setting because of their drug use, appearance (including track marks on their arms), or housing situation, which may discourage them from seeking care.
“And this is not just one case; this is a trend that I’m seeing with people who use drugs,” Walters tells PGN. “Someone said, ‘If I overdose, I’m not even going to the [emergency room] to get help because of this, because of the way I’m treated. Because I know I’m going to be treated differently.’”
People experience stigma not only because of their addiction, but also because of other aspects of their identities, Walters says, including “immigration or race and ethnicity. Hispanic folks, brown folks, Black folks [are] being treated differently and experiencing different outcomes.”
And despite the effective harm reduction tools and treatment options available for SUD, research has shown that stigma creates barriers to access.
Syringe services programs, for example, provide infectious disease testing, Narcan, and fentanyl test strips. These programs have been proven to save lives and reduce the spread of HIV and hepatitis C. SSPs don’t increase crime, but they’re often mistakenly “viewed by communities as potential settings of drug-related crime;” this myth persists despite decades of research proving that SSPs make communities safer.
To improve this bias, Walters says it’s helpful for people to take a step back and recognize how we use substances, like alcohol, in our own lives, while also humanizing those with addiction. She says, “There’s a lack of understanding that these are human beings and people … [who] are living lives, and many times very functional lives.”
Misconceptions lead to stigma
SUD results from changes in the brain that make it difficult for a person to stop using a substance. But research has shown that a big misconception that leads to stigma is that addiction is a choice and reflects a person’s willpower.
Michelle Maloney, executive clinical director of mental health and addiction recovery services for Rogers Behavioral Health, tells PGN that statements such as “you should be able to stop” can keep a patient from seeking treatment. This belief goes back to the 1980s and the War on Drugs, she adds.
“We think about public service announcements that occurred during that time: ‘Just say no to drugs,’” Maloney says. “People who have struggled, whether that be with nicotine, alcohol, or opioids, [know] it’s not as easy as just saying no.”
Stigma can worsen addiction
Stigma can also lead people with SUD to feel guilt and shame and blame themselves for their medical condition. These feelings, according to the National Institute on Drug Abuse, may “reinforce drug-seeking behavior.”
In a 2020 article, Dr. Nora D. Volkow, the director of NIDA, said that “when internalized, stigma and the painful isolation it produces encourage further drug taking, directly exacerbating the disease.”
Overall, research agrees that stigma harms people experiencing addiction and can make the condition worse. Experts also agree that debunking myths about the condition and using non-stigmatizing language (like saying someone is a person with a substance use disorder, not an addict) can go a long way toward reducing stigma.

Relieve GERD and Acid Reflux with Stretches and Exercises
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.
Looking for relief from GERD or acid reflux? Today we’re featuring an amazing video by Dr. Jo, packed with stretches and exercises designed to ease those symptoms.
Here’s a quick rundown, in case you don’t have time to watch the whole video.
If you’re not familiar with GERD, you can find our simple explanation of GERD here. Or, if you’re on the other end of the spectrum and want to do a deeper dive on the topic, we reviewed a great book on the topic).
1. Mobilize Your SEM Muscle
The sternocleidomastoid (SEM) muscle, if tight, can aggravate acid reflux. Dr. Jo shows how to gently mobilize this muscle by turning your head while holding the SEM in place. It’s simple but effective.
2. Portrait Pose Stretch
Stretch out that SEM with the Portrait Pose. Place your hand on your collarbone, turn your head away, side bend, and look up. Hold for 30 seconds. You’ll feel the tension melting away.
3. Seated Cat-Cow Motion
Open up your stomach area with this easy exercise. Sit down, roll your body forward, arch your back (Cow), then curl your spine and tuck your chin (Cat). Alternate for 30 seconds and feel the difference.
4. Quadruped Cat-Cow with Breathing
Similar to the seated cat-cow, the quadruped cat-cow focuses on flexing the lower spine whilst on all fours. Bonus tip: focus on deep belly breathing during the exercise. This helps improve digestion and ease reflux symptoms.
5. Exaggerated Pelvic Tilt
Lie on your back and tilt your pelvis back and forth. This loosens up the abdominal area and helps everything flow better.
6. Trunk Rotation
Lie down, bend your knees, and rotate them to one side. Hold for 30 seconds, then switch sides. It’s a great way to relax and stretch your abdominal muscles.
We know this is a quick overview (sorry if it seems rushed!), but if you have a few more minutes on your hand you can watch the whole video below.
Feel better soon! And if you have any favorite tips or videos to share, email us at 10almonds.

What Happens To Your Body When You Plank 1 Minute Every Day
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.
Planks improve strength, flexibility, balance, posture, reduce chronic back pain, lower blood pressure, and enhance physique. But can we really get benefits from just 1 minute per day?
To the core
The benefits that can be expected, according to the science cited in this video, include:
- Within 2–3 weeks, daily planking of just 1 minute per day activates deep core muscles, enhancing balance, which helps in everyday tasks and prevents muscle imbalances.
- Strengthening core muscles through planks also helps alleviate lower back pain, with research supporting its effectiveness within 3 weeks.
- Posture is important for good health, and planks align the spine and hips, improving posture naturally, which also helps alleviate back issues. So, there’s a good kind of synergy to this exercise.
- Of course, many people exercising have the goal of a more toned body; regular planking leads to a toned core, sculpted shoulders, and leaner legs.
- For those who care more about mobility, though, planking enhances flexibility in hamstrings, feet, and toes within 4–6 weeks.
- Anything else? Yes, isometric exercises like planks are highly effective at reducing blood pressure, and, counterintuitively, more so than aerobic exercises.
The video also looks at a study in which participants did 20 minutes per day instead of 1, which predictably also significantly improved strength, endurance, flexibility, and reduced body fat.
However, another study cited gives the stats for just 1 minute daily, and that was not even a whole minute, so much as 30 seconds hold, 1 minute rest, 30 seconds hold—and still showed very good improvements.
