154 million lives saved in 50 years: 5 charts on the global success of vaccines

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.

  • Spiced Fruit & Nut Chutney

    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.

    ‘Tis the season to make the chutney that will then be aged chutney when you want it later! And unlike supermarket varieties with their ingredients list that goes “Sugar, spirit vinegar, inverted glucose-fructose syrup,” this one has an array of health-giving fruits and nuts (just omit the nuts if you or someone you may want to give this to has an allergy), and really nothing bad in here at all. And of course, tasty healthful spices!

    You will need

    • 2 red onions, chopped
    • 1½ cups dried apricots, chopped
    • 1½ cups dried figs, chopped
    • 1 cup raisins
    • ½ cup apple cider vinegar
    • ½ cup slivered almonds
    • ½ lime, chopped and deseeded
    • ¼ bulb garlic, chopped
    • 1 hot pepper, chopped (your choice what kind; omit if you don’t like heat at all; multiply if you want more heat)
    • 2 tablespoons honey or maple syrup (omit for a less sweet chutney; there is sweetness in the dried fruits already, after all)
    • 1 tbsp freshly grated ginger
    • 2 tsp sweet cinnamon
    • 1 tsp nutmeg
    • 1 tsp black pepper
    • ½ teaspoon allspice
    • ½ MSG or 1 tsp low-sodium salt
    • Extra virgin olive oil

    Method

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

    1) Heat some oil in a heavy-based pan that will be large enough for all ingredients to go into eventually. Fry the onions on a gentle heat for around 15 minutes. We don’t need to caramelize them yet (this will happen with time), but we do want them soft and sweet already.

    2) Add the ginger, garlic, and chili, and stir in well.

    3) When the onions start to brown, add the fruit and stir well to mix thoroughly.

    4) Add the honey or maple syrup (if using), and the vinegar; add the remaining spices/seasonings, so everything is in there now except the almonds.

    5) Cook gently for another 30 minutes while stirring. At some point it’ll become thick and sticky; add a little water as necessary. You don’t want to drown it, but you do want it to stay moist. It’ll probably take only a few tablespoons of added water in total, but add them one at a time and stir in before judging whether more is needed. By the end of the 30 minutes, it should be more solid, to the point it can stand up by itself.

    6) Add the almonds, stir to combine, and leave to cool. Put it in jars until you need it (or perhaps give it as gifts).

    Alternative method: if you don’t want to be standing at a stove stirring for about an hour in total, you can use a slow cooker / crock pot instead. Put the same ingredients in the same order, but don’t stir them, just leave them in layers (this is because of the pattern of heat distribution; it’ll be hotter at the bottom, so the things that need to be more cooked should be there, and the design means they won’t burn) for about two hours, then stir well to mix thoroughly, and leave it for another hour or two, before turning it off to let it cool. Put it in jars until you need it (or perhaps give it as gifts).

    Enjoy!

  • Red Lentils vs Green Lentils – Which is Healthier?

    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.

    Our Verdict

    When comparing red lentils to green lentils, we picked the green.

    Why?

    Yes, they’re both great. But there are some clear distinctions!

    First, know: red lentils are, secretly, hulled brown lentils. Brown lentils are similar to green lentils, just a little less popular and with (very) slightly lower nutritional values, as a rule.

    By hulling the lentils, the first thing that needs mentioning is that they lose some of their fiber, since this is what was removed. While we’re talking macros, this does mean that red lentils have proportionally more protein, because of the fiber weight lost. However, because green lentils are still a good source of protein, we think the fat that green lentils have much more fiber is a point in their favor.

    In terms of micronutrients, they’re quite similar in vitamins (mostly B-vitamins, of which, mostly folate / vitamin B9), and when it comes to minerals, they’re similarly good sources of iron, but green lentils contain more magnesium and potassium.

    Green lentils also contain more antixoidants.

    All in all, they both continue to be very respectable parts of anyone’s diet—but in a head-to-head, green lentils do come out on top (unless you want to prioritize slightly higher protein above everything else, in which case, red).

  • Peach vs Passion Fruit – Which is Healthier?

    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.

    Our Verdict

    When comparing peach to passion fruit, we picked the passion fruit.

    Why?

    It wasn’t close!

    In terms of macros, passion fruit has more than 2x the protein, 2x the carbs, and 7x the fiber. That’s a big difference!

    In the category of vitamins, peach has more of vitamins B1, B5, E, and K, while passion fruit has more of vitamins A, B2, B3, B6, B7, B9, C, and choline. Again, not close.

    When it comes to minerals, peach has more manganese and zinc, while passion fruit has more calcium, copper, iron, magnesium, phosphorus, potassium, and selenium—and most of those margins are “by multiples”, not just a fraction more. Again, a clear winner here.

    Adding up these three overwhelming wins for passion fruit makes for an obvious total win for passion fruit.

    As ever, enjoy both, but if you’re going to pick one, then one of these fruits is extra passionate about bringing you nutrients.

  • Why is toddler milk so popular? Follow the money

    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.

    Toddler milk is popular and becoming more so. Just over a third of Australian toddlers drink it. Parents spend hundreds of millions of dollars on it globally. Around the world, toddler milk makes up nearly half of total formula milk sales, with a 200% growth since 2005. Growth is expected to continue.

    We’re concerned about the growing popularity of toddler milk – about its nutritional content, cost, how it’s marketed, and about the impact on the health and feeding of young children. Some of us voiced our concerns on the ABC’s 7.30 program recently.

    But what’s in toddler milk? How does it compare to cow’s milk? How did it become so popular?

    What is toddler milk? Is it healthy?

    Toddler milk is marketed as appropriate for children aged one to three years. This ultra-processed food contains:

    • skim milk powder (cow, soy or goat)
    • vegetable oil
    • sugars (including added sugars)
    • emulsifiers (to help bind the ingredients and improve the texture)
    • added vitamins and minerals.

    Toddler milk is usually lower in calcium and protein, and higher in sugar and calories than regular cow’s milk. Depending on the brand, a serve of toddler milk can contain as much sugar as a soft drink.

    Even though toddler milks have added vitamins and minerals, these are found in and better absorbed from regular foods and breastmilk. Toddlers do not need the level of nutrients found in these products if they are eating a varied diet.

    Global health authorities, including the World Health Organization (WHO), and Australia’s National Health and Medical Research Council, do not recommend toddler milk for healthy toddlers.

    Some children with specific metabolic or dietary medical problems might need tailored alternatives to cow’s milk. However, these products generally are not toddler milks and would be a specific product prescribed by a health-care provider.

    Toddler milk is also up to four to five times more expensive than regular cow’s milk. “Premium” toddler milk (the same product, with higher levels of vitamins and minerals) is more expensive.

    With the cost-of-living crisis, this means families might choose to go without other essentials to afford toddler milk.

    How toddler milk was invented

    Toddler milk was created so infant formula companies could get around rules preventing them from advertising their infant formula.

    When manufacturers claim benefits of their toddler milk, many parents assume these claimed benefits apply to infant formula (known as cross-promotion). In other words, marketing toddler milks also boosts interest in their infant formula.

    Manufacturers also create brand loyalty and recognition by making the labels of their toddler milk look similar to their infant formula. For parents who used infant formula, toddler milk is positioned as the next stage in feeding.

    How toddler milk became so popular

    Toddler milk is heavily marketed. Parents are told toddler milk is healthy and provides extra nutrition. Marketing tells parents it will benefit their child’s growth and development, their brain function and their immune system.

    Toddler milk is also presented as a solution to fussy eating, which is common in toddlers.

    However, regularly drinking toddler milk could increase the risk of fussiness as it reduces opportunities for toddlers to try new foods. It’s also sweet, needs no chewing, and essentially displaces energy and nutrients that whole foods provide.

    Growing concern

    The WHO, along with public health academics, has been raising concerns about the marketing of toddler milk for years.

    In Australia, moves to curb how toddler milk is promoted have gone nowhere. Toddler milk is in a category of foods that are allowed to be fortified (to have vitamins and minerals added), with no marketing restrictions. The Australian Competition & Consumer Commission also has concerns about the rise of toddler milk marketing. Despite this, there is no change in how it’s regulated.

    This is in contrast to voluntary marketing restrictions in Australia for infant formula.

    What needs to happen?

    There is enough evidence to show the marketing of commercial milk formula, including toddler milk, influences parents and undermines child health.

    So governments need to act to protect parents from this marketing, and to put child health over profits.

    Public health authorities and advocates, including us, are calling for the restriction of marketing (not selling) of all formula products for infants and toddlers from birth through to age three years.

    Ideally, this would be mandatory, government-enforced marketing restrictions as opposed to industry self-regulation in place currently for infant formulas.

    We musn’t blame parents

    Toddlers are eating more processed foods (including toddler milk) than ever because time-poor parents are seeking a convenient option to ensure their child is getting adequate nutrition.

    Formula manufacturers have used this information, and created a demand for an unnecessary product.

    Parents want to do the best for their toddlers, but they need to know the marketing behind toddler milks is misleading.

    Toddler milk is an unnecessary, unhealthy, expensive product. Toddlers just need whole foods and breastmilk, and/or cow’s milk or a non-dairy, milk alternative.

    If parents are worried about their child’s eating, they should see a health-care professional.

  • The Myth of Normal – by Dr. Gabor Maté and Daniel Maté

    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 lot of popular beliefs (and books!) start with the assumption that everyone is, broadly speaking, “normal”. That major diversions from “normal” happen only to other people… And that minor diversions from “normal” are just something to suck up and get over—magically effecting a return to “normalcy”.

    Dr. Maté, however, will have none of these unhelpful brush-offs, and observes that in fact most if not all of us have been battered by the fates one way or another. We just:

    • note that we have more similarities than differences, and
    • tend to hide our own differences (to be accepted) or overlook other people’s (to make them more acceptable).

    How is this more helpful? Well, the above approach isn’t always, but Mate has an improvement to offer:

    We must see flawed humans (including ourselves) as the product of our environments… and/but see this a reason to look at improving those environments!

    Beyond that…

    The final nine chapters of the books he devotes to “pathways to wholeness” and, in a nutshell, recovery. Recovery from whatever it was for you. And if you’ve had a life free from anything that needs recovering from, then congratulations! You doubtlessly have at least one loved one who wasn’t so lucky, though, so this book still makes for excellent reading.

    Dr. Maté was awarded the Order of Canada for his medical work and writing. His work has mostly been about addiction, trauma, stress, and childhood development. He co-wrote this book with his son, Daniel.

  • Toasted Chick’n Mango Tacos

    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.

    Tacos aren’t generally held up as the world’s healthiest food, but they can be! There’s so much going on in this dish today, healthwise, in a good way, that it’s hard to know where to start. But suffice it to say, these tacos are great for your gut, heart, blood sugars, and more.

    You will need

    For the chickpeas:

    • 1 can chickpeas, drained
    • 1 tbsp ras el-hanout*
    • 1 tsp red pepper flakes
    • ½ tsp MSG or 1 tsp low-sodium salt
    • Extra virgin olive oil

    *You can easily make this yourself; following our recipe (linked above in the ingredients list) will be better than buying it ready-made, and if you have strong feelings about any of the ingredients, you can adjust per your preference.

    For the tahini sauce:

    • ⅓ cup tahini
    • 2 tbsp apple cider vinegar
    • 2 tbsp finely chopped fresh dill
    • ¼ bulb garlic, minced
    • 1 tsp red pepper flakes
    • ½ tsp black pepper, coarse ground

    It may seem like salt is conspicuous by its absence, but there is already enough in the chickpeas component; you do not want to overwhelm the dish. Trust us that enjoying these things together will be well-balanced and delicious as written.

    For the mango relish:

    • ½ mango, pitted, peeled, and cubed
    • 2 tsp apple cider vinegar
    • 2 tsp cilantro, finely chopped (substitute with parsley if you have the “cilantro tastes like soap” gene)
    • 1 tsp red pepper flakes

    For building the taco:

    • Soft corn tortillas
    • Handful of arugula
    • 1 avocado, pitted, peeled, and sliced
    • ½ red onion, sliced

    Method

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

    1) Heat a sauté pan with a little olive oil in; add the chickpeas and then the rest of the ingredients from the chickpea section; cook for about 5 minutes, stirring frequently, and set aside.

    2) Combine the tahini sauce ingredients in a small bowl, stirring in ¼ cup water, and set aside.

    3) Combine the mango relish ingredients in a separate small bowl, and set aside. You can eat the other half of the mango if you like.

    4) Lightly toast the tortillas in a dry skillet, or using a grill.

    5) Assemble the tacos; we recommend the order: tortillas, arugula, avocado slices, chickpeas, mango relish, red onion slices, tahini sauce.

    Enjoy!
