Small-Scale Question Sunday for February 23, 2025

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

When vaccinating your kid (a US citizen) what vaccination schedule should you go with?

  1. The standard US one

  2. The standard of a different country which you think is better run (I picked Denmark)

  3. Something else

I had a discussion with Grok 3 about this, and it seemed like it wanted to defend the US schedule (35 shots) until I pressed it about the Danish schedule (11 shots). Then it claimed that US schedule is necessary in the US because of different socioeconomic conditions. It seems like the US recommendations are based on helping the underclasses. For example, Hep B. My wife doesn't have Hep B. My kid won't get Hep B as a child. But a kid whose mom is a prostitute very much needs to be vaccinated for Hep B at birth.

In any case, after the censorship and disinformation promulgated by the US health agencies during the pandemic, I don't trust them. And clearly there is a corrupting profit motive here too. In this corrupted epistemic environment we simply don't know what the effects of giving kids 35 vaccine shots (plus annual flu and Covid shots) will be. I make no strong claims about vaccine injuries, and I think most vaccines are net positive. But I think, for my child, the Danish schedule + chicken pox is sufficient. At a minimum, I am deadset against any Covid vaccines. Can't say I look forward to arguing with nurses about this.

I’m also going to ask you to reconsider.

I realize I may have little credibility with you. Maybe this comes across like those cave diver signs. But I seriously think there’s nothing on this hill worth dying for. You’re accepting a mild risk for literally zero benefit.

The main differences between our and Denmark’s schedules appear to be COVID, Hep A and B, rotavirus, and varicella. I could make cases for most of those. Rotavirus is vaccinated in most countries; I don’t know why Denmark declined. Varicella has lower uptake, either because of cost or because it’s risky when only children are covered. On the other hand, I had it as a small child. It sucked, I still have a couple minor scars, and I get to be at risk for shingles in the future.

We’ve given ~84% of children immunity to Hep B worldwide. Between that and Universal Precautions, your child will probably be fine without such immunity. Though it’ll still be wise if he or she goes into medicine, works with the less fortunate, or wants to visit Africa or Southeast Asia. And it’s generally better to be prepared.

These vaccines aren’t novel. Everything except the COVID shots has been on our schedule since 2001. We have had decades to learn about potential side effects. We’ve also had significant political shifts. Assuming that it’s all fake and gay because of the Current Thing is a mistake. Assuming such because of a chatbot’s medical opinions is worse.

Skip the COVID shots if you want, especially if you don’t have any old or obese relatives watching the kids. But please stick with the rest of the standard schedule.

Excellent comment. One thing I'd like to add is that opting out of vaccination is, to an extent, mooching off the commons.

Herd immunity doesn't work, if parents look at the existing vaccination rates, reasons that their kids will be fine without vaccination as "everyone else" does it, and thus defects.

Yes, it is absolutely being a freeloader, and that's one reason why I have opted out for my own children. I don't think enough other people have bought in to the common good, and so I don't see any reason to subject my children to autoimmune disease for some supposed public good that I see constantly denigrated by others. Another casualty of lowering the trust of society. I don't think it's worth it, but that trade has already been made without anyone asking me.

My kid had very bad eczema due to the oral rotavirus vaccine, and after that I simply said no thank you.

This comment is a travesty. If it wasn't clear, it is the majority of parents opting-in for scheduled vaccinations that's what creates the commons for you to free-ride off.

Even in a purely disinterested cost-benefit analysis, the odds of your child getting an autoimmune disease from vaccines is so low that the general benefit of them getting sick less often outweighs it. The number of people avoiding vaccination isn't at the point where you're benefiting from opting out, or pointing to others doing so as an excuse. The majority of vaccines are net positive in expectation, regardless of what others do.

Meta-rationality is a hard art to practice. You point to a minority of people hitting defect to defect just as hard.

It was very clear, and I know about the free rider problem from undergraduate economics. I am actively choosing to be a free rider, and relying on others to do what I am choosing not to. That's what free rider means. Other people are paying, I'm choosing not to.

I'm doing that because I am an individual, not a herd animal, and the things I do must actually benefit me in order for me to do them. I have no shepherd who owns me and is responsible for the herd to which I belong. There exists the possibility of a world where I do things for others altruistically, but that world is not this one, and the conditions for such a world are far from being met.

Defect is the rational response to defection, and tit for tat wins iterated prisoner's dilemmas.

the odds of your child getting an autoimmune disease from vaccines is so low that the general benefit of them getting sick less often outweighs it.

I don't trust your calculations, mostly because I don't fear the diseases or believe in their prevalence. I see the risks as miniscule, but deliberately overblown in order to create a far response and enforce compliance. There is no guarantee I even encounter measles or hepatitis or haemophilic influenza b, but if I take the vaccine there is a 100% exposure rate to the contents of the shot.

Furthermore, my children can simply get the shots later in life, when they are grown and have a much larger body mass with which to accommodate, after development has been mostly completed.

The eczema finally went away, and there's no way to know the counterfactual, but I think if we were on schedule I'd still be seeing rashes all over the back and legs and ankles.

I don't trust your calculations

You can't trust what I haven't presented. I could do so, and I strongly expect to be correct, but I already do enough trawling of medical literature when I'm being paid for it.

It's your child, and I have some respect for your right to make decisions on their behalf, even if I think they're bad decisions.

Furthermore, my children can simply get the shots later in life, when they are grown and have a much larger body mass with which to accommodate, after development has been mostly completed.

My man, you're going from wrong to confused. There's good reason why you don't see doctors or nurses pull out dose calculators to account for body weight when giving every vaccine I can think of it. It's because it doesn't matter. If little Tommy is 4'6 and 35 kilos or 4'9 and 45 makes next to no difference, and this holds true once you're past the size of a premature infant on death's door, going to a land whale who needs a mobility scooter. Vaccines aren't like paracetamol, the dose-response curves are VERY different when it's the immune system we're talking about. Someone with a peanut allergy isn't twice as likely to die if you give them two peanuts versus one.

The eczema finally went away, and there's no way to know the counterfactual, but I think if we were on schedule I'd still be seeing rashes all over the back and legs and ankles

You're not doing a good job at probabilistic reasoning, but an eczematous rash is a minor vaccine reaction, and of very little consequence. If it was life threatening, I presume you'd have pointed that out, and even then, you'd be better off consulting your pediatrician about whether they could narrow it down to a particular constituent of the two common rotavirus vaccines in the States (fetal bovine serum or porcine circovirus, if I had to guess from looking at composition), and take precautions when administering future vaccines with similar compositions. Believe it or not, most doctors would be happy to answer those questions and offer reassurance if warranted, especially if you're paying them.

I think you can use this sort of pseudo-science to justify vaccines post hoc. You can also use the same pseudo-science to justify not taking them at all.

I know quite a few people who got lasting side effects from the Covid vax, and it’s nearly heretical to talk about it. (These are people I know IRL, not internet reports) That alone makes me extremely skeptical about anyone saying how there are ~zero risks from any and all vaccines. Why is there a giant propaganda campaign to cover up the risks? Am I just some crazy statistical outlier who knows 3+ people very closely who’ve been vaccine maimed, even though it “hardly ever occurs” in the general population? I wouldn’t bet on that

I would, I guess.

Adverse reactions are going to cluster for one reason or another.

People win the lottery despite the odds not being in their favor.

If you've bought a ticket, and then you find a million pounds in your bank account, then congratulations, knowing that the odds were stacked against you doesn't mean you've not won.

I know literally zero people who have been "vaccine maimed". I used to be responsible for a COVID ICU before vaccines too, and I can definitely tell you that I saw plenty die of it.

It is far more likely that you are either:

  1. Lying. On the internet, anyone can be a dog, or claim to be one.

  2. Mistaken.

  3. Surrounded by people who are mistaken or lying.

Assuming 150 people you could "closely know" (Dunbar's number as a first approximation), then someone, somewhere, out there in the world will find 3 people who were harmed by vaccines. Because vaccines are not perfectly safe, and I've never claimed that. If you consider people who are mistaken about their illness being caused by a vaccine, then the number skyrockets.
