Stuck is a rather short book at 127 pages, not counting the notes at the back. There is also an introduction of about 30 pages, so let's say 150 pages. Despite that, it took me several days to finish it. I struggled with Larson's writing, which is thorough and intelligent and a lot more diplomatic that I would be on this subject—but not very engaging. There's also the occasional typo or other small error that a good editor should have caught.
Mainly, though, it's just such a frustrating subject. I am strongly pro-vaccine, pro-science, etc. I have no sympathy for anti-vaxxers and struggle to comprehend what mental world they're living in. As Ethan Lindenberger (a pro-vaccine activist of anti-vax parents) put it, "There are misinformed ideas that there is even a debate around vaccines. That's not true. The debate around vaccines is a lie. That is misinformation in itself. The science has decided vaccines are safe and effective. Legitimizing the idea that there is a debate around vaccines is dangerous, it is a problem in itself."
This book tries to explain the causes and stories behind vaccine rumors, including by providing examples of various anti-vax rumors and campaigns. Reading about these events can be infuriating. For example, Larson describes how, in Kenya, a group of Catholic bishops who didn't appreciate not being consulted by a polio vaccine campaign responded by discouraging followers from getting the vaccine. To think of the harm they're causing and for what reasons, and to think how hard scientists worked to invent this much-needed vaccine in the first place and how bad polio can be... I found myself having to put this book down a lot to go take some deep breaths.
Ultimately I am glad I read this book. Larson debunks the view I had held, that all it takes to handle anti-vaxxers is a good dose of true scientific information. As her book reveals, the real causes of anti-vax sentiments are more complex, and so must be our response.
One big factor is the human communication element of vaccination. "Vaccine acceptance is about a relationship," Larson writes, "about putting trust in scientists..., industries that produce [vaccines], health professionals who deliver them, and the institutions that govern them. That trust chain is a far more important lever of acceptance than any piece of information" (xxxv). I learned from this book that the way doctors handle a patient's doubts and questions about vaccines can be so, so important. Apparently some people who feel unheard or dismissed or disrespected by their doctor become suspicious and turn to anti-vax resources for answers instead (yikes).
A lot of these resources are online these days, but you can't just blame it on social media. Larson argues that this is bigger than social media. In a physical sense, the reach of anti-vax propaganda extends beyond social media to billboards, pamphlets, etc. More abstractly, anti-vax sentiment is not a fluke; it's tied to a lot of other schools of thought, like homeopathy, distrust of government, and a broader preference for anti-chemical, organic, natural products. I found this passage especially interesting:
There is something powerful, almost religiously compelling for some, when it comes to trust in nature. When disease happens 'naturally' it is somehow more acceptable and begets less guilt than would any potential side effects from a vaccine. Psychologists call it the 'omission bias,' where choosing *not* to take an action, such as not getting a vaccination and instead letting nature take its course, feels like a lesser risk with less culpability, even when that action would ultimately reduce a greater risk.
As you can see from this, the decision not to vaccinate is not just a result of faulty logic or poor research skills. It's also got a strong emotional pull for some people, especially from a "natural lifestyle" perspective. Apparently a lot of misinformed anti-vaxxers think the body's immune system is enough and it would be better to expose their kids to, say, chickenpox than give them the chickenpox vaccine because that way it's more natural. This line of thinking is especially appealing in an age where we don't regularly see the awful effects of the worst viruses—vaccines work so well that these viruses are rarer and seem like more of a distant or abstract danger.
Then on the other hand, you have people who are not anti-vaxxers, simply people who are too complacent about certain viruses because the virus is too ordinary. Larson uses the example of the flu shot. People are really not scared enough of flu, considering how bad it can be and how many people it kills every year. A lot of people who are not anti-vaxxers just don't bother to get their annual flu shot. Larson includes a sad anecdote here about one young woman who died of flu after not bothering to get her flu shot.
One of the more bizarre aspects of vaccine rumors is the phenomenon of psychosomatic vaccine reactions. That is, sometimes a group of vaccinated people will all come down with similar symptoms that are caused not by the vaccine but by anxiety about the vaccine. I found it particularly ironic that one type of anti-vax "vaccine danger" is actually caused by anti-vaxxers stirring up fear, not by the actual (safe) vaccine.
Larson's conclusion is arguably the most powerful and eloquent part of the book, especially this passage:
A Babelian mix of truths, partial truths, and intentional lies has taken a toll on public trust in science. Waning vaccine confidence, skepticism about the safety and even the need for vaccines, and an overall tectonic shift away from trusting 'experts' to having more confidence in the opinions and 'evidence' shared in stories circulating among neighbors, friends, colleagues, and online social networks speak to a near reversal of the Age of Enlightenment... There is widespread trust in anything natural, tangible, and untampered with by modern man... As epidemiologist Stephen Ledeer rightly points out, 'Facts are not rejected because they are seen as being wrong, but because they are seen as being irrelevant' (117).
Ignorance is scary, especially mass ignorance.
While Larson doesn't think we can eradicate anti-vax beliefs, she does point out the problems that fan the flames of these rumors and explain why it's so important to work on the anti-vax problem instead of dismissing it, as I tend to do, as a fringe group of ignorant people. The issue goes beyond the health of the individual. We have a "planetary vaccine dependency" (126). And vaccine acceptance can be seen as a measure of the health of a society:
The quality of life that most of us enjoy today is dependent on vaccines. In many ways it is one of the biggest worldwide social experiments in collectivism and cooperation in modern times. The challenge is that it depends on a social contract whose fabric is eroding in a broader context of anti-globalization, nationalism, and populism (126).
In light of that, I hope more people will read this book, especially anyone who wants to understand anti-vaxxers or try to make a dent in their numbers.
