The Truth About Vaccines
Yesterday we asked your views on vaccines, and we got an interesting spread of answers. Of those who responded to the poll, most were in favour of vaccines. We got quite a lot of comments this time too; we can’t feature them all, but we’ll include extracts from a few in our article today, as they raised interesting points!
Vaccines contain dangerous ingredients that will harm us more than the disease would: True or False?
False, contextually.
Many people are very understandably wary of things they know full well to be toxic, being injected into them.
One subscriber who voted for “Vaccines are poison, and/or are some manner of conspiracy ” wrote:
❝I think vaccines from 50–60 years ago are true vaccines and were safer than vaccines today. I have not had a vaccine for many, many years, and I never plan to have any kind of vaccine/shot again.❞
They didn’t say why they personally felt this way, but the notion that “things were simpler back in the day” is a common (and often correct!) observation regards health, especially when it comes to unwanted additives and ultraprocessing of food.
Things like aluminum or mercury in vaccines are much like sodium and chlorine in table salt. Sodium and chlorine are indeed both toxic to us. But in the form of sodium chloride, it’s a normal part of our diet, provided we don’t overdo it.
Additionally, the amount of unwanted metals (e.g. aluminum, mercury) in vaccines is orders of magnitude smaller than the amount in dietary sources—even if you’re a baby and your “dietary sources” are breast milk and/or formula milk.
In the case of formaldehyde (an inactivating agent), it’s also the dose that makes the poison (and the quantity in vaccines is truly miniscule).
This academic paper alone cites more sources than we could here without making today’s newsletter longer than it already is:
Vaccine Safety: Myths and Misinformation
I have a perfectly good immune system, it can handle the disease: True or False?
True! Contingently.
In fact, our immune system is so good at defending against disease, that the best thing we can do to protect ourselves is show our immune system a dead or deactivated version of a pathogen, so that when the real pathogen comes along, our immune system knows exactly what it is and what to do about it.
In other words, a vaccine.
One subscriber who voted for “Vaccines are important but in some cases the side effects can be worse ” wrote:
❝In some ways I’m vacd out. I got COVid a few months ago and had no symptoms except a cough. I have asthma and it didn’t trigger a lot of congestion. No issues. I am fully vaccinated but not sure I’ll get one in fall.❞
We’re glad this subscriber didn’t get too ill! A testimony to their robust immune system doing what it’s supposed to, after being shown a recent-ish edition of the pathogen, in deactivated form.
It’s very reasonable to start wondering: “surely I’m vaccinated enough by now”
And, hopefully, you are! But, as any given pathogen mutates over time, we eventually need to show our immune system what the new version looks like, or else it won’t recognize it.

So why don’t we need booster shots for everything? Often, it’s because a pathogen has stopped mutating at any meaningful rate. Polio is an example of this—no booster is needed for most people in most places.
Others, like flu, require annual boosters to keep up with the pathogens.
Herd immunity will keep us safe: True or False?
True! Ish.
But it doesn’t mean what a lot of people think it means. For example, in the UK, “herd immunity” was the strategy promoted by Prime Minister of the hour, Boris Johnson. But he misunderstood what it meant:
- What he thought it meant: everyone gets the disease, then everyone who doesn’t die is now immune
- What it actually means: if most people are immune to the disease (for example: due to having been vaccinated), it can’t easily get to the people who aren’t immune
One subscriber who voted for “Vaccines are critical for our health; vax to the max! ” wrote:
❝I had a chiropractor a few years ago, who explained to me that if the general public took vaccines, then she would not have to vaccinate her children and take a risk of having side effects❞
Obviously, we can’t speak for this subscriber’s chiropractor’s children, but this raises a good example: some people can’t safely have a given vaccine, due to underlying medical conditions—or perhaps it is not available to them, for example if they are under a certain age.
In such cases, herd immunity—other people around having been vaccinated and thus not passing on the disease—is what will keep them safe.
Here’s a useful guide from the US Dept of Health and Human Services:
How does community immunity (a.k.a. herd immunity) work?
And, for those who are more visually inclined, here’s a graphical representation of a mathematical model of how herd immunity works (you can run a simulation)!
Stay safe!

When should you get the updated COVID-19 vaccine?
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.
Updated COVID-19 vaccines are now available: They’re meant to give you the best protection against the strain of the virus that is making people severely sick and also causing deaths.
Many people were infected during the persistent summer wave, which may leave you wondering when you should get the updated vaccine. The short answer is that it depends on when you last got infected or vaccinated and on your particular level of risk.
We heard from six experts—including medical doctors and epidemiologists—about when they recommend getting an updated vaccine. Read on to learn what they said. And to make it easy, check out the flowchart below.
A flowchart to help you decide when is the best time to get the 2024-2025 updated COVID-19 vaccine. If I was infected with COVID-19 this summer, when should I get the updated vaccine?
All the experts we spoke to agreed that if you were infected this summer, you should wait at least three months since you were infected to get vaccinated.
“Generally, an infection may be protective for about three months,” Dr. Ziyad Al-Aly, chief of research and development at the Veterans Affairs St. Louis Health Care System, tells PGN. “If they got infected three or more months ago, it is a good idea to get vaccinated sooner than later.”
This three-month rule applies if you got vaccinated over the summer, which may be the case for some immunocompromised people, adds Dr. Peter Chin-Hong, professor of medicine at the University of California, San Francisco.
If I didn’t get infected with COVID-19 this summer, when should I get vaccinated?
Most of the experts we talked to say that if you didn’t get infected with COVID-19 this summer, you should get the vaccine as soon as possible. Dr. Peter Hotez, dean of the National School of Tropical Medicine at Baylor College of Medicine, emphasizes that if this applies to you, you should get vaccinated as soon as possible, especially given the current COVID-19 surge.
Al-Aly agrees. “Vaccine-derived immunity lasts for several months, and it should cover the winter season. Plus, the current vaccine is a KP.2-adapted vaccine, so it will work most optimally against KP.2 and related subvariants [such as] KP.3 that are circulating now,” Al-Aly says. “We don’t know when the virus will mutate to a variant that is not compatible with the KP.2 vaccine.”
Al-Aly adds that if you’d rather take the protection you can get right now, “It may make more sense to get vaccinated sooner than later.”
This especially applies if you’re over 65 or immunocompromised and you haven’t received a COVID-19 vaccine in a year or more because, as Chin-Hong adds, “that is the group that is being hospitalized and disproportionately dying now.”
Some experts—including epidemiologist Katelyn Jetelina, author of newsletter Your Local Epidemiologist—also say that if you’re younger than 65 and not immunocompromised, you can consider waiting and aiming to get vaccinated before Halloween to get the best protection in the winter, when we’re likely to experience another wave because of the colder weather, gathering indoors, and the holidays.
“I am more worried about the winter than the summer, so I would think of October (some time before Halloween) as the ‘Goldilocks moment’—not too early, not too late, but just right,” Chin-Hong adds. Time it “such that your antibodies peak during the winter when COVID-19 cases are expected to exceed what we are seeing this summer.”
My children are starting school—should I get them vaccinated now?
According to most experts we spoke to, now is a good time to get your children vaccinated.
Jennifer Nuzzo, professor of epidemiology and director of the Pandemic Center at the Brown University School of Public Health, adds that “with COVID-19 infection levels as high as they are and increased exposures in school,” now is a particularly good time to get an updated vaccine if people haven’t gotten COVID-19 recently.
Additionally, respiratory viruses spike when kids are back in school, so “doing everything you can to reduce your child’s risk of infection can help protect families and communities,” says epidemiologist Jessica Malaty Rivera, science communications advisor at the de Beaumont Foundation.

Radical Remission – by Dr. Kelly Turner
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.
First, what this is not:an autobiographical account of the “I beat cancer and you can too” pep-talk style.
What it is: a very readable pop-science book based on the author’s own PhD research into radical remission.
She knew that a very small percentage of people experience spontaneous radical remission (or quasi-spontaneous, if the remission is attributed to lifestyle changes, and/or some alternative therapy), but a small percentage of people means a large number worldwide, so she travelled the world studying over 1,000 cases of people with late-stage cancer who had either not gone for conventional anticancer drugs, or had and then stopped, and lived to tell the tale.
While she doesn’t advocate for any particular alternative therapy, she does report on what things came to her attention. She does advocate for some lifestyle changes.
Perhaps the biggest value this book offers is in its promised “9 key factors that can make a real difference”, which are essentially her conclusions from her PhD dissertation.
There isn’t room to talk about them here in a way that wouldn’t be misleading/unhelpful for a paucity of space, so perhaps we’ll do a main feature one of these days.
Bottom line: if you have (or a loved one has) cancer, this is an incredibly sensible book to read. If you don’t, then it’s an interesting and thought-provoking book to read.

Caffeine: Cognitive Enhancer Or Brain-Wrecker?
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 Two Sides Of Caffeine
We asked you for your health-related opinions on caffeine itself, not necessarily the coffee, tea, energy drinks, etc that might contain it.
We have, by the way previously written about the health effects of coffee and tea specifically:
As for our question about caffeine itself, though, we got the above-depicted, below-described, set of results:
- About 59% said “caffeine is a safe stimulant and cognitive enhancer”
- About 31% said “caffeine is a moderately safe recreational drug”
- About 8% said “caffeine’s addictive properties make it de facto bad”
- One (1) person said “caffeine will leave you a trembling exhausted wreck”
But what does the science say?
Caffeine is addictive: True or False?
True, though one will find occasional academics quibbling the definition. Most of the studies into the mechanisms of caffeine addiction have been conducted on rats, but human studies exist too and caffeine is generally considered addictive for humans, for example:
See also:
Notwithstanding its addictive status, caffeine is otherwise safe: True or False?
True-ish, for most people. Some people with heart conditions or a hypersensitivity to caffeine may find it is not safe for them at all, and for the rest of us, the dose makes the poison. For example:
❝Can too much caffeine kill you? Although quite rare, caffeine can be fatal in cases of overdose; such circumstances are generally not applicable to healthy individuals who typically consume caffeine via beverages such as tea or coffee.❞
this paper, by the way, also includes a good example of academics quibbling the definition of addiction!
Caffeine is a cognitive enhancer: True or False?
True, but only in the case of occasional use. If you are using it all the time, your physiology will normalize it and you will require caffeine in order to function at your normal level. To attain higher than that, once addicted to caffeine, would now require something else.

Caffeine will leave you a trembling exhausted wreck: True or False?
True or False depending on usage:
- The famously moderate 3–5 cups per day will not, for most people, cause any such problems.
- Using/abusing it to make up for lost sleep (or some other source of fatigue, such as physical exhaustion from exertion), however, is much more likely to run into problems.
In the latter case, caffeine really is the “payday loan” of energy! It’ll give you an adrenal boost now (in return, you must suffer the adrenal dumping later, along with lost energy expended in the adrenaline surge), and also, the tiredness that you thought was gone, was just caffeine’s adenosine-blocking activities temporarily preventing you from being able to perceive the tiredness. So you’ll have to pay that back later, with interest, because of the extra time/exertion too.
Want to make caffeine a little more gentle on your system?
Taking l-theanine alongside caffeine can ameliorate some of caffeine’s less wonderful effects—and as a bonus, l-theanine has some nifty benefits of its own, too:
Enjoy!

The Vitamin Solution – by Dr. Romy Block & Dr. Arielle Levitan
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 quick note: it would be remiss of us not to mention that the authors of this book are also the founders of a vitamin company, thus presenting a potential conflict of interest.
That said… In this reviewer’s opinion, the book does seem balanced and objective, regardless.
We talk a lot about supplements here at 10almonds, especially in our Monday Research Review editions. And yesterday, we featured a book by a doctor who hates supplements. Today, we feature a book by two doctors who have made them their business.
The authors cover all the most common vitamins and minerals popularly enjoyed as supplements, and examine:
- why people take them
- factors affecting whether they help
- problems that can arise
- complicating factors
The “complicating factors” include, for example, the way many vitamins and/or minerals interplay with each other, either by requiring the presence of another, or else competing for resources for absorption, or needing to be delicately balanced on pain of diverse woes.
This is the greatest value of the book, perhaps; it’s where most people go wrong with supplementation, if they go wrong.
While both authors are medical doctors, Dr. Romy Block is an endocrinologist specifically, and she clearly brought a lot of extra attention to relevant metabolic/thyroid issues, and how vitamins and minerals (such as thiamin and iron) can improve or sabotage such, depending on various factors that she explains. Informative, and so far as this reviewer could see, objective and well-balanced.
Bottom line: supplementation is a vast and complex topic, but this book does a fine job of demystifying and simplifying it in a clear and objective fashion, without resorting to either scaremongering or hype.

F*ck You Chaos – by Dominika Choroszko
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’ve all read decluttering books. Some may even have decluttering books cluttering bookshelves. This one’s a little different, though:
Dominika Choroszko looks at assessing, decluttering, and subsequently organizing:
- Your home
- Your mind
- Your finances
In other words
- she starts off like Marie Kondo, and…
- phases through doing the jobs of Queer Eye’s “Fab Five”, before…
- sitting us down with some CBT worksheets, and…
- finally going through finances à la Martin Lewis.
By the time we’ve read the book, it’s as though Mary Poppins has breezed through our house, head, and bank account, leaving everything “practically perfect in every way”.
Of course, it’s on us to actually do the work, but as many of us struggle with “how” and the ever-dreaded “but where to begin”, Choroszko’s whirlwind impetus and precision guidance (many very direct practical steps to take) really grease the wheels of progress.
In short, this could be the book that kickstarts your next big “getting everything into better order” drive, with a clear step-by-step this-then-this-then-this linear process.

What You Don’t Know Can Kill You
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.
Knowledge Is Power!
This is Dr. Simran Malhotra. She’s triple board-certified (in lifestyle medicine, internal medicine, and palliative care), and is also a health and wellness coach.
What does she want us to know?
Three things:
Wellness starts with your mindset
Dr. Malhotra shifted her priorities a lot during the initial and perhaps most chaotic phase of the COVID pandemic:
❝My husband, a critical care physician, was consumed in the trenches of caring for COVID patients in the ICU. I found myself knee-deep in virtual meetings with families whose loved ones were dying of severe COVID-related illnesses. Between the two of us, we saw more trauma, suffering, and death, than we could have imagined.
The COVID-19 pandemic opened my eyes to how quickly life can change our plans and reinforced the importance of being mindful of each day. Harnessing the power to make informed decisions is important, but perhaps even more important is focusing on what is in our control and taking action, even if it is the tiniest step in the direction we want to go!❞
~ Dr. Simran Malhotra
We can only make informed decisions if we have good information. That’s one of the reasons we try to share as much information as we can each day at 10almonds! But a lot will always depend on personalized information.
There are one-off (and sometimes potentially life-saving) things like health genomics:
The Real Benefit Of Genetic Testing
…but also smaller things that are informative on an ongoing basis, such as keeping track of your weight, your blood pressure, your hormones, and other metrics. You can even get fancy:
Track Your Blood Sugars For Better Personalized Health
Lifestyle is medicine
It’s often said that “food is medicine”. But also, movement is medicine. Sleep is medicine. In short, your lifestyle is the most powerful medicine that has ever existed.
Lifestyle encompasses very many things, but fortunately, there’s an “80:20 rule” in play that simplifies it a lot because if you take care of the top few things, the rest will tend to look after themselves:
These Top Few Things Make The Biggest Difference To Overall Health
Gratitude is better than fear
If we receive an unfavorable diagnosis (and let’s face it, most diagnoses are unfavorable), it might not seem like something to be grateful for.
But it is, insofar as it allows us to then take action! The information itself is what gives us our best chance of staying safe. And if that’s not possible e.g. in the worst case scenario, a terminal diagnosis, (bearing in mind that one of Dr. Malhotra’s three board certifications is in palliative care, so she sees this a lot), it at least gives us the information that allows us to make the best use of whatever remains to us.

Which is very important!
…and/but possibly not the cheeriest note on which to end, so when you’ve read that, let’s finish today’s main feature on a happier kind of gratitude:
