How anti-vaccine figures abuse data to trick you

The anti-vaccine movement is nearly as old as vaccines themselves. For as long as humans have sought to harness our immune system’s incredible ability to recognize and fight infectious invaders, critics and conspiracy theorists have opposed these efforts.
Anti-vaccine tactics have advanced since the early days of protesting “unnatural” smallpox inoculation, and the rampant abuse of scientific data may be the most effective strategy yet.
Here’s how vaccine opponents misuse data to deceive people, plus how you can avoid being manipulated.
Misappropriating raw and unverified safety data
Perhaps the oldest and most well-established anti-vaccine tactic is the abuse of data from the federal Vaccine Adverse Event Reporting System, or VAERS. The Centers for Disease Control and Prevention and the Food and Drug Administration maintain VAERS as a tool for researchers to detect early warning signs of potential vaccine side effects.
Anyone can submit a VAERS report about any symptom experienced at any point after vaccination. That does not mean that these symptoms are vaccine side effects.
VAERS was not designed to determine if a specific vaccine caused a specific adverse event. But for decades, vaccine opponents have misinterpreted, misrepresented, and manipulated VAERS data to convince people that vaccines are dangerous.
Anyone relying on VAERS to draw conclusions about vaccine safety is probably trying to trick you. It isn’t possible to determine from VAERS data alone if a vaccine caused a specific health condition.
VAERS isn’t the only federal data that vaccine opponents abuse. Originally created for COVID-19 vaccines, V-safe is a vaccine safety monitoring system that allows users to report—via text message surveys—how they feel and any health issues they experience up to a year after vaccination. Anti-vaccine groups have misrepresented data in the system, which tracks all health experiences, whether or not they are vaccine-related.
The U.S. Department of Defense’s Defense Medical Epidemiology Database (DMED) has also become a target of anti-vaccine misinformation. Vaccine opponents have falsely claimed that DMED data reveals massive spikes in strokes, heart attacks, HIV, cancer, and blood clots among military service members since the COVID-19 vaccine rollout. The spike was due to an updated policy that corrected underreporting in the previous years
Misrepresenting legitimate studies
A common tactic vaccine opponents use is misrepresenting data from legitimate sources such as national health databases and peer-reviewed studies. For example, COVID-19 vaccines have repeatedly been blamed for rising cancer and heart attack rates, based on data that predates the pandemic by decades.
A prime example of this strategy is a preliminary FDA study that detected a slight increase in stroke risk in older adults after a high-dose flu vaccine alone or in combination with the bivalent COVID-19 vaccine. The study found no “increased risk of stroke following administration of the COVID-19 bivalent vaccines.”
Yet vaccine opponents used the study to falsely claim that COVID-19 vaccines were uniquely harmful, despite the data indicating that the increased risk was almost certainly driven by the high-dose flu vaccine. The final peer-reviewed study confirmed that there was no elevated stroke risk following COVID-19 vaccination. But the false narrative that COVID-19 vaccines cause strokes persists.
Similarly, the largest COVID-19 vaccine safety study to date confirmed the extreme rarity of a few previously identified risks. For weeks, vaccine opponents overstated these rare risks and falsely claimed that the study proves that COVID-19 vaccines are unsafe.
Citing preprint and retracted studies
When a study has been retracted, it is no longer considered a credible source. A study’s retraction doesn’t deter vaccine opponents from promoting it—it may even be an incentive because retracted papers can be held up as examples of the medical establishment censoring so-called “truthtellers.” For example, anti-vaccine groups still herald Andrew Wakefield nearly 15 years after his study falsely linking the measles, mumps, and rubella (MMR) vaccine to autism was retracted for data fraud.
The COVID-19 pandemic brought the lasting impact of retracted studies into sharp focus. The rush to understand a novel disease that was infecting millions brought a wave of scientific publications, some more legitimate than others.
Over time, the weaker studies were reassessed and retracted, but their damage lingers. A 2023 study found that retracted and withdrawn COVID-19 studies were cited significantly more frequently than valid published COVID-19 studies in the same journals.
In one example, a widely cited abstract that found that ivermectin—an antiparasitic drug proven to not treat COVID-19—dramatically reduced mortality in COVID-19 patients exemplifies this phenomenon. The abstract, which was never peer reviewed, was retracted at the request of its authors, who felt the study’s evidence was weak and was being misrepresented.
Despite this, the study—along with the many other retracted ivermectin studies—remains a touchstone for proponents of the drug that has shown no effectiveness against COVID-19.
In a more recent example, a group of COVID-19 vaccine opponents uploaded a paper to The Lancet’s preprint server, a repository for papers that have not yet been peer reviewed or published by the prestigious journal. The paper claimed to have analyzed 325 deaths after COVID-19 vaccination, finding COVID-19 vaccines were linked to 74 percent of the deaths.
The paper was promptly removed because its conclusions were unsupported, leading vaccine opponents to cry censorship.
Applying animal research to humans
Animals are vital to medical research, allowing scientists to better understand diseases that affect humans and develop and screen potential treatments before they are tested in humans. Animal research is a starting point that should never be generalized to humans, but vaccine opponents do just that.
Several animal studies are frequently cited to support the claim that mRNA COVID-19 vaccines are dangerous during pregnancy. These studies found that pregnant rats had adverse reactions to the COVID-19 vaccines. The results are unsurprising given that they were injected with doses equal to or many times larger than the dose given to humans rather than a dose that is proportional to the animal’s size.
Similarly, a German study on rat heart cells found abnormalities after exposure to mRNA COVID-19 vaccines. Vaccine opponents falsely insinuated that this study proves COVID-19 vaccines cause heart damage in humans and was so universally misrepresented that the study’s author felt compelled to dispute the claims.
The author noted that the study used vaccine doses significantly higher than those administered to humans and was conducted in cultured rat cells, a dramatically different environment than a functioning human heart.
How to avoid being misled
The internet has empowered vaccine opponents to spread false information with an efficiency and expediency that was previously impossible. Anti-vaccine narratives have advanced rapidly due to the rampant exploitation of valid sources and the promotion of unvetted, non-credible sources.
You can avoid being tricked by using multiple trusted sources to verify claims that you encounter online. Some examples of credible sources are reputable public health entities like the CDC and World Health Organization, personal health care providers, and peer-reviewed research from experts in fields relevant to COVID-19 and the pandemic.

5 Steps To Quit Sugar Easily
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.
Sugar is one of the least healthy things that most people consume, yet because it’s so prevalent, it can also be tricky to avoid at first, and the cravings can also be a challenge. So, how to quit it?
Step by step
Dr. Mike Hansen recommends the following steps:
- Be aware: a lot of sugar consumption is without realizing it or thinking about it, because of how common it is for there to be added sugar in things we might purchase ready-made, even supposedly healthy things like yogurts, or easy-to-disregard things like condiments.
- Recognize sugar addiction: a controversial topic, but Dr. Hansen comes down squarely on the side of “yes, it’s an addiction”. He wants us to understand more about the mechanics of how this happens, and what it does to us.
- Reduce gradually: instead of going “cold turkey”, he recommends we avoid withdrawal symptoms by first cutting back on liquid sugars like sodas, juices, and syrups, before eliminating solid sugar-heavy things like candy, sugar cookies, etc, and finally the more insidious “why did they put sugar in this?” added-sugar products.
- Find healthy alternatives: simple like-for-like substitutions; whole fruits instead of juices/smoothies, for example. 10almonds tip: stuffing dates with an almond each makes it very much like eating chocolate, experientially!
- Manage cravings: Dr. Hansen recommends distraction, and focusing on upping other healthy habits such as hydration, exercise, and getting more vegetables.

Red Light Therapy Every Day For 5 Years (Plus New Research)!
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.
And how to get the most out of the correct kind of device:
There’s no stopping this red light
Over the past 5 years, the use of red light therapy (RLT) has moved from being a fringe “biohack” to a more mainstream, research-backed tool.
It’s not new, though! RLT originated in the 1960s when a Hungarian scientist observed improved wound healing and hair growth in rodents exposed to low-level red light.
Now here in the modern era, strong evidence supports red light therapy for wound healing, collagen production, skin health, and treating hair loss, nerve damage in extremities, and age-related macular degeneration.
Going down the list, less certain but promising applications include muscle recovery, ameliorating depression symptoms, managing the pain of conditions ranging from osteoarthritis to fibromyalgia, and improving metabolic and cardiovascular health.
How it works: it’s not magic; red and near-infrared light stimulate mitochondria by interacting with cytochrome c oxidase, increasing ATP production and thus cellular energy. Other mechanisms include reactive oxygen species signaling for tissue repair and nitric oxide release to improve oxygen availability.
What kind of device is best: simpler devices with red (around 660nm) and near-infrared (around 830nm) wavelengths are more effective than more complex devices with additional wavelengths (including multicolored lights).
This is particularly important as wavelengths above 1000nm or below 500nm can irritate sensitive skin and (ironically) cause redness rather than calming effects.
As with many things, consistent use—ideally daily or at least 5 times per week—is necessary to see noticeable benefits.
And of course, results are best supported by a broader routine including skincare (e.g. tretinoin), diet, exercise, and sleep, rather than relying on RLT to do all the work alone. Your body is, after all, a system of systems, and works best when treated holistically!

No, your aches and pains don’t get worse in the cold. So why do we think they do?
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.
It’s cold and wet outside. As you get out of bed, you can feel it in your bones. Your right knee is flaring up again. That’ll make it harder for you to walk the dog or go to the gym. You think it must be because of the weather.
It’s a common idea, but a myth.
When we looked at the evidence, we found no direct link between most common aches and pains and the weather. In the first study of its kind, we found no direct link between the temperature or humidity with most joint or muscle aches and pains.
So why are so many of us convinced the weather’s to blame? Here’s what we think is really going on.
fongbeerredhot/Shutterstock Weather can be linked to your health
The weather is often associated with the risk of new and ongoing health conditions. For example, cold temperatures may worsen asthma symptoms. Hot temperatures increase the risk of heart problems, such as arrhythmia (irregular heartbeat), cardiac arrest and coronary heart disease.
Many people are also convinced the weather is linked to their aches and pains. For example, two in every three people with knee, hip or hand osteoarthritis say cold temperatures trigger their symptoms.
Musculoskeletal conditions affect more than seven million Australians. So we set out to find out whether weather is really the culprit behind winter flare-ups.
What we did
Very few studies have been specifically and appropriately designed to look for any direct link between weather changes and joint or muscle pain. And ours is the first to evaluate data from these particular studies.
We looked at data from more than 15,000 people from around the world. Together, these people reported more than 28,000 episodes of pain, mostly back pain, knee or hip osteoarthritis. People with rheumatoid arthritis and gout were also included.
We then compared the frequency of those pain reports between different types of weather: hot or cold, humid or dry, rainy, windy, as well as some combinations (for example, hot and humid versus cold and dry).
Bad back on a cold day? We wanted to know if the weather was really to blame. Pearl PhotoPix/Shutterstock What we found
We found changes in air temperature, humidity, air pressure and rainfall do not increase the risk of knee, hip or lower back pain symptoms and are not associated with people seeking care for a new episode of arthritis.
The results of this study suggest we do not experience joint or muscle pain flare-ups as a result of changes in the weather, and a cold day will not increase our risk of having knee or back pain.
In order words, there is no direct link between the weather and back, knee or hip pain, nor will it give you arthritis.
It is important to note, though, that very cold air temperatures (under 10°C) were rarely studied so we cannot make conclusions about worsening symptoms in more extreme changes in the weather.
The only exception to our findings was for gout, an inflammatory type of arthritis that can come and go. Here, pain increased in warmer, dry conditions.
Gout has a very different underlying biological mechanism to back pain or knee and hip osteoarthritis, which may explain our results. The combination of warm and dry weather may lead to increased dehydration and consequently increased concentration of uric acid in the blood, and deposition of uric acid crystals in the joint in people with gout, resulting in a flare-up.
Why do people blame the weather?
The weather can influence other factors and behaviours that consequently shape how we perceive and manage pain.
For example, some people may change their physical activity routine during winter, choosing the couch over the gym. And we know prolonged sitting, for instance, is directly linked to worse back pain. Others may change their sleep routine or sleep less well when it is either too cold or too warm. Once again, a bad night’s sleep can trigger your back and knee pain.
Likewise, changes in mood, often experienced in cold weather, trigger increases in both back and knee pain.
So these changes in behaviour over winter may contribute to more aches and pains, and not the weather itself.
Believing our pain will feel worse in winter (even if this is not the case) may also make us feel worse in winter. This is known as the nocebo effect.
When it’s cold outside, we may be less active. Anna Nass/Shutterstock What to do about winter aches and pains?
It’s best to focus on risk factors for pain you can control and modify, rather than ones you can’t (such as the weather).
You can:
- become more physically active. This winter, and throughout the year, aim to walk more, or talk to your health-care provider about gentle exercises you can safely do at home, with a physiotherapist, personal trainer or at the pool
- lose weight if obese or overweight, as this is linked to lower levels of joint pain and better physical function
- keep your body warm in winter if you feel some muscle tension in uncomfortably cold conditions. Also ensure your bedroom is nice and warm as we tend to sleep less well in cold rooms
- maintain a healthy diet and avoid smoking or drinking high levels of alcohol. These are among key lifestyle recommendations to better manage many types of arthritis and musculoskeletal conditions. For people with back pain, for example, a healthy lifestyle is linked with higher levels of physical function.

Glucose Revolution – by Jessie Inchauspé
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.
While we all know that keeping balanced blood sugars is important for all us (be we diabetic, pre-diabetic, or not at all), it can be a mystifying topic!
Beyond a generic “sugar is bad”…
- What does it all mean and how does it all work?
- Should we go low-carb?
- What’s the deal with fruit?
- Carbs or protein for breakfast?
- Is “quick energy” ever a good thing?
- How do starches weigh in again?
It’s all so confusing!
Happily, Jessie Inchauspé has the incredible trifecta of qualifications to help us: she’s a biochemist, a keen cook, and a great educator. What we mean by this latter is:
Instead of dry textbook explanations, or “trust me” hand-waives, she explains biochemistry in a clear, simple, digestible (if you’ll pardon the pun) way with very helpful diagrams what things cause (or flatten) blood sugar spikes and how and why. If you read this book, you will understand, without guesswork or gaps, exactly what is happening on a physical level, and why and how her “10 hacks” work.
Her “10 hacks” are explained so thoroughly that each gets a chapter of its own, but we’ll not keep them a mystery from you meanwhile, they are:
- Eat foods in the right order
- Add a green starter to your meals
- Stop counting calories
- Flatten your breakfast curve
- Have any type of sugar you like—they’re all the same
- Pick dessert over a sweet snack
- Reach for the vinegar before you eat
- After you eat, move
- If you have to snack, go savoury
- Put some clothes on your carbs
She then finishes up with a collection of handy cheat-sheets and some of her own recipes.
Bottom line: this isn’t just a “how-to” book. It gives the how-to, yes, but it also gives such good explanations that you’ll never be confused again by what’s going on in your glucose-related health.

5 Tips For Muscle Growth As A Woman
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.
Building muscle improves your body composition, as you’ll be leaner even at a higher weight. It supports insulin sensitivity, boosts metabolic health, and helps break through weight loss plateaus while improving overall performance and hormone balance. In short, it’s a very healthful thing to do.
But there are ways people can err, so here’s how to do it best:
Mistakes to avoid
There are five key things to bear in mind:
- Don’t obsess over the scale: your overall bodyweight will probably increase; don’t worry about that; it doesn’t mean you have necessarily put on fat. Indeed, muscle weighs more than fat in any case.
- Don’t worry about eating too much: unless you really go out of your way to overeat, eating larger amounts according to your hunger will not result in overeating. Simply, your body needs more fuel in order to build muscle, and that’s fine and is to be expected.
- Don’t overdo cardio: it’s easy to think “I must stay trim while putting on muscle” and look to cardio to facilitate that, but the reality is that strength training will boost your metabolism anyway, whereas cardio can sap your energy that was needed for muscle-building (and, famously, can result in a metabolic slump)
- Don’t go too easy… or too hard! Lest that seem like a difficult directive to follow, this means: train hard yes, but make sure to get adequate rest also! Both are critical for muscle growth—without hard training, your muscle will have no reason to grow, and without rest, your body will be unable to do more than maintenance at most. So: train hard, rest well.
- Don’t eat junk just to hit calorie/macro goals. Quality still matters, even if the numbers are higher than you’d normally be taking.

Before You Take Amlodipine, The Most Popular Blood Pressure Medication…
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.
Dr. Alex Wibberley talks about its pros and cons:
Under pressure
Amlodipine is a calcium channel blocker, meaning that it blocks calcium from entering smooth muscle cells, which prevents tightening, widens your arteries, and reduces the force your heart needs to pump.
For this reason, it’s commonly prescribed to treat hypertension and angina.
A note about when you start: blood pressure starts dropping within 24–48 hours, but the full effect takes about 7–8 days because the drug builds up gradually. For this reason, it’s important to take it once daily at a consistent time—morning or evening doesn’t matter, consistency does.
Now for some negatives:
- Common side effects: ankle swelling, flushing, and early headaches are all side effects, though they are usually mild and caused by widened blood vessels.
- Important limitations: it controls blood pressure directly, but doesn’t address underlying the causes like diet, weight, inactivity, or stress.
Consequently, it may be worth considering the DASH diet, which can lower systolic blood pressure by around 5–10 mmHg, which is similar to a standard dose of amlodipine.
