The toll of the anti-vaccination movement, in one devastating graphic

tl;dr: We need a new vaccine. Tilting at small populations of anti-vaxxers may feel satisfying, but it is ultimately counterproductive, especially in this case.
The study, conducted on animals, does not, however, suggest that the vaccine increases rate of disease spread, rather that vaccinated individuals can serve as unaffected and unsuspecting nodes of transmission. This can happen with the acellular type of vaccine, not the whole-cell.
tl;dr: "We missed a spot." Which is going to happen. I don't think it validates being anti-every-vaccine, but it does validate asking questions and furthering research (and ceasing the vilification of the population that does ask questions!).
EDIT: particularly so, given the follow-ups to your comment's sibling, citing animal studies demonstrating exactly the thing claimed: that even vaccinated individuals can transmit the disease.
More pressingly, Kid #3 could have any number of pressing medical issues that mean they cannot be vaccinated, and are thus vulnerable.
The understanding of the effects of vaccinating kid #1 isn't all about kid #1 being immune to the infection. Instead it is that kid #1 is x% less susceptible to contracting the infection if exposed.
So you might wonder, how could Small Pox be much extinct if the vaccine is only about 95% effective, and how have we wiped out an enormous number of diseases that caused immense suffering in the 20th century using vaccines that were not 100% effective in protecting the vaccinated from infection on an individual level?
The lesson is that common sense can be a terrible guide for even the roughest approximations of the dynamics of a system. Dispersion models explain the limits to how far water will trickle down through soil or the conditions under which wild fires will burn themselves out. The models for infectious diseases involve variables for the likelihood of transmission, mortality rates, how long you're contagious until you show symptoms, the percentage of population that is susceptible etc.
While even common sense will tell you that the best way to avoid a disease is to avoid contact, it might not tell you that vaccinating populations is largely about reducing exposure. Assume our hypothetical situation has kids one through eight living on a street and they only play with their immediate neighbor. Then let's assume that the kids have a natural resistance of 20%, but 60% if they are vaccinated. If kid #8 has the disease, what is kid #1's risk of exposure if everyone is vaccinated vs no one is vaccinated?
(1-20%)^6 = 26%
(1-60%)^6 = 0.4%
I think those numbers are astonishing and beat the tar out of what common sense has to say. Of course more realistic models would show many more links between nodes as well as lower transmission rates, but differences of even a hundredth of a percent in a population of 320 million is 32 thousand people.
The conversation begins with: "The issue is not black and white — and laying the entire issue at the feet of non-vaccinated is blatant propaganda." If we're going to use extreme language, then it is "blatantly wrong" to say it is "blatant propaganda". The portion of people who defect from or cooperate with vaccination programs does matter. It isn't much of a problem if there is one Jenny McCarthy, but it becomes a problem if she advocates on behalf of defection to everyone else in her playgroup, or worse to other parents around the country.
While it is a good instinct to assume that issues aren't simple, it is tempting to see issues as having "two sides" and that the middle ground must be reasonable. I don't understand why newer/safer vaccines being less effective is being presented as a middle ground. If the "two sides" are not vaccinating and vaccinating, then this argument would not be in between the two, but instead it should be an argument that is more extreme than a mere decision to vaccinate. And yet, I think it serves to create uncertainty instead, and ultimately fewer vaccinations and lower resistance in the population.
As Fomite pointed out, partial immunity. If the vaccines aren't 100% effective, then yeah, we definitely want more people to get them.
You have one historical fact misreported there. It is clear that the current acellular vaccines were adopted because of safety concerns about former cellular pertussis vaccines. What's actually NOT clear is whether those safety concerns really necessitated changing the vaccine formula. It appears that anti-vaccine activists may have exaggerated the risk profile of cellular vaccines and understated their effectiveness while campaigning to reduce vaccine use in general.
Here's a post-marketing study about the increased safety profile of the acellular vaccines vs. the cellular vaccines: http://www.ncbi.nlm.nih.gov/pubmed/8620224
As it is, I have no idea what measles rates were like 10 or 20 years ago. I have to research that myself, which makes it less than devastating.
So, for example, this graphic is somewhat more devastating:

Sorry.

(With "<90% vaccination coverage" and "highly religious" having an almost 1:1 correlation...)
More devastating would be to know how many are actually dying of measles/pertussis. I can't find any legitimate, non-anti-vax sources talking about that, except the WHO, who says that measles deaths declined 71% worldwide between 2000 and 2011, (anti-devestating! Hooray!) and also that 95% of measles deaths occur in low-income countries. Hmm.
I think this is a lesson we should all take care to note: be humble. Knowing something doesn't mean we know everything, and it can hurt us to think so.
People seem to assume that all doctors are roughly equal, or at least meet some baseline level of competency. I'm saying based on my experience in the engineering world and my first hand experience with doctors I don't believe that. So I'm saying that just taking someones word for it because they are a doctor is naive. I've lost track of the number of times I've been told totally nonsensical things by doctors that were just not sound advice which I confirmed by seeking another doctor's opinion and in some cases because what they told me to do made me sicker.
You might not say it, but you'd probably think, "really? You probably don't know a function from a hole in the ground."
Personally, I can't tell you what all of my organs do, much less what can go wrong with them, much less how that should be treated. I'm sure there are incompetent doctors, but I doubt there are many less competent at medicine than I am.
Luckily this isn't relevant to vaccinations because we're not relying on what one person says, but on an accumulated body of research.
Vaccination for varicella is tricky - if you're going to vaccinate against it, you need to vaccinate hard. It's a great working example of what's known as the "Paradox of Moderate Infection Control" - getting a handle on it just a little bit will cause worse outcomes than if you did nothing at all. The WHO then, making recommendations for the entire world, logically favors a single "Do it and be done" shot that piggybacks on their incredibly intensive campaigns for MMR vaccination.
In the U.S., a varicella vaccine is a co-occuring part of the recommended vaccine schedule. It's a question of one shot or two, and managing slightly worse side effects for the MMRV vaccine, and thus absolutely sensical to leave it to the clinician and parent to discuss, because the likelihood of the child getting one and never getting the other is quite low, it's just a question of how.
It's also a conversation that's pretty orthogonal to most anti-vaccine discussions, so it feels like a bit of a red herring.
They're done by panels of doctors who are experts in that field, and the supporting reasoning is extensive and the result of many, many peer-reviewed studies.
I'd certainly trust a random doctor's medical opinion over a random programmer's (my own). And I think a doctor should trust a random programmer's opinion about software over his/her own.
In both cases, the solution is to find a reputable practitioner, not substitute an untrained opinion for a trained one.
If anyone knows the research I am referring to, I'd love to look at it again.
Hacker news, reporting on the reporting of reporting of reporting of news.
“Better diagnosis and reporting of whooping cough may be contributing to the increased numbers, along with the fact that the disease tends to peak and wane in cycles. It does not appear that anti-vaccination sentiment among parents has contributed…”
My instinct is generally towards politeness[0] so it goes against my nature to get up in people's faces. But I'm wondering if I need to take a hard line on vaccination when it comes to who I allow to spend time with my kid.
[0]: See http://www.math.uh.edu/~tomforde/hquotes.html, the quote on p247.
One of my middle school classmates (from India) had leg deformities from polio, and could not walk without the help of crutches. He couldn't participate in most school activities, and was teased often. I wasn't able to find out why he wasn't vaccinated, but he was from a wealthy family so we always assumed they were in the anti-vaccination camp. Can you imagine being in his place? He has to suffer for his entire life because of a dumb decision that his parents made.
BTW I realize that polio vaccination does not require painful injections, but just pointing out that there are severe downsides to not vaccinating your child. Most certainly severe than a few jabs.
I'm definitely dancing to the Dr's office with my kids to get them vaccinated (when scheduled). There are a lot of vaccines early on, which makes sense, because little kids are highly vulnerable. It eases up as they get older; it's been years since either of my kids got jabbed.
Most kids just cry for a bit and get a sore arm, a statistically small percent get a true adverse reaction. It's simply not worth the risk to not vaccinate.
Then we get some shots.
Then we do another dance, which has an accompanying song entitled "I just extended you lifespan!"
We also talk about how we're going to get more vaccinations before our next trip because the India has crazy mosquitos and Costa Rica could have bad water.
Vaccinations are wondrous. It isn't that much work to get your expectations to match.
Is someone claiming they love to dance to the doctor to see their child in pain?
I have a newborn. He has been upset, in pain, and sick in his first 6 months - we always try to do what is best for him, our family, his health, and public health. Dancing or allowing his discomfort to heavily bias our decisions never even remotely occurred to us.
Unvaccinated children who contract a disease are only a threat to other unvaccinated children, who are generally unvaccinated by choice. Not sure why this is a public health issue.
Vaccines are not force fields that prevent you from contracting a disease. They just lower your chances considerably. So an unvaccinated child can infect vaccinated children.
Vaccinating "eradicates" disease in that it lowers the overall chance of transmission to the point where the disease can't effectively spread. A bunch of unvaccinated kids raises that overall chance back up and can cause outbreaks.
Given mumps is endemic in much of the developing world, especially northern india, pakistan and sub-saharan africa, could the measles outbreak in much of europe be in (unvaccinated and potentially partially contaminated) immigrant communities rather than a specific anti-vaccination movements?
As for some of the other countries in Europe, while there's less of a vocal anti-vaxx movement, the vaccination rate in the Swiss has been dropping for the better part of a decade now.
I rather vividly remember a presentation given by PAHO a couple years ago on their rubella control efforts in South America, and how frustrating it was to have outbreaks kicked off by import cases from wealthier European and North American countries.

What's the disadvantage of the mobile site on a desktop?
The URL typically contains a token that would indicate it. In this case, the URL is "touch." but you also typically see "m." or "mobile."
> What's the disadvantage of the mobile site on a desktop?
Depends on the site. In the case of LA Times, it works very well. Other sites have a bad Mobile -> Desktop experience just like they have a poor Desktop -> Mobile experience.
Either way, I don't give a damn. I'm just playing Devil's Advocate.
The only difference is with the LA Times is it turned out decent looking. This is the second mobile site I clicked on today and the other one was horrible for desktop.

here is remarkably problematic. It's good that this graphic has a lot of uptake and spread around the Internet, but I had to go back through a chain of about four repostings to find the map as it started out. The team at the producers of the original map should study more usability for Web display of data as they prepare to share this important message.

Seems to be a lot more mumps and rubella there, especially Eastern Europe.
People tell me I should not worry about the Daily Mail. They can print all they like, what's the harm? Well, here it is.
Also, it looks like some of the bubbles are duplicates, one is 4000 in California, then one from a few months later is 5000 and it looks like the 5000 is a report that just adds 1000 more to the previous report, but it's counted as two separate things.
The fact that they are endorsing the MMR vaccine is probably good reason not to take it all.
The exception is perhaps influenza, but that's mainly because the flu vaccine is one of the few "moving target" viruses we have a vaccine against.
It's because RNA transcription doesn't have error checking.
Nor does an unstable antigen profile (ala HIV or influenza) necessarily imply more severe disease.
A huge amount of research into how vaccines are deployed is, and is done by, people with skill in applied mathematics.
But anybody licensed to practice has spent a lot more time studying medicine that your average coder or engineer. Among the matters they have studied is the current best understanding of vaccines. It isn't the guy last in his class who's coming up with the recommendations that the others follow. And what's best for you in your narrow little case is very likely most of the time what's best for the "herd".
You have undoubtedly met fewer doctors and fewer coders and engineers than I have. (I'm older than most people on HN.) Anyway, IQ is not the relevant issue. The issue is specific training and clinical experience. For equal IQ scores, I will ask engineers to solve my engineering problems, and doctors to diagnose and treat my diseases. If each professional has passed the required training course and has continued in practice with a license with good reputation, I don't need to ask IQ scores before I seek a doctor or seek a coder. What's important is getting the work done right, and doctors have better background for doing medical work than engineers or coders.
