Why are Unvaccinated Kids a Threat if Vaccines Work?

Bizarre picture of white woman picking at her wrist accompanied by question: Why would my unvaccinated kids be a threat to your vaccinated kids, if you're so sure that vaccines work?This morning, a friend sent me the “electronic card” you see here on the right. On it, an odd image of a woman picking at her wrist is accompanied by the question, “Why would my unvaccinated kids be a threat to your vaccinated kids, if you’re so sure that vaccines work?”

My friend doesn’t want me to actually answer this question; she has been resolutely opposed to vaccines for years now and there’s little to nothing that would change her mind. Rather, she’s trying to change my mind with what’s supposed to be a rhetorical question. Oh dear, I am supposed to respond, why I just don’t know! But I’m not going to answer that way.  Instead, I’m going to treat the question as if it were a sincere one, hoping that there might be some other people out there who have heard the question themselves and who are sincerely interested in hearing how somebody might answer.

With that in mind, here are my answers.  I’m not a doctor or a biologist, so it wouldn’t be fair to interpret these answers as professional or perfect.  This is just what I’d say in conversation, which means I’m opening to hear your answers, further questions and other thoughts as well. There’s a comments section at the bottom of this post and I’d love it if you would use it to share what you have to say. All that said, here are my thoughts:

There’s a faulty assumption behind this “gotcha” question, one that becomes clear if we try to extend it to other kinds of risk:

What's the problem with me driving drunk all over town, if you're so sure that seat belts work? Why should I wash my hands after going to the bathroom, if you're so sure that washing your own hands works? Why are you worried about shooting off my pistol in the town square, if you're so sure that bulletproof vests hurt?

These questions are clearly absurd because the understanding of how solutions “work” in the questions is so limited. Seat belts and bulletproof vests and washing your own hands “work” because they reduce the risk of car injury, projectile injury, and infection, but nobody would claim that they protect people infallibly, all the time. A drunk driver can still hurt and kill people in a collision, even if those people are wearing seat belts. Some bullets can pierce bulletproof vests, and those vests don’t cover the whole body. No matter how carefully you wash your own hands, washing just isn’t going to remove every last germ.  Besides, you’re probably going to end up touching surfaces, food or drink in the world after you’ve washed, and if they’ve been touched by someone who doesn’t wash, you still can easily get infected.

These ways of protecting yourself aren’t perfect. Would we therefore say that washing one’s hands, or wearing a seat belt when on the road, or wearing a bulletproof vest in response to a shooter, is absurd and useless? Of course not.  Why? Because these acts significantly lower risk of harm. I also think most reasonable people would also agree it is unsafe to drive drunk, or to shoot a pistol in a town square, or to stop washing hands after using a bathroom. Why? Because these acts significantly increase the risk of harm.

The “why would my unvaccinated kids be a threat to your vaccinated kids, if you’re so sure that vaccines work?” question is similarly absurd because it assumes that “vaccines work” means “vaccines provide 100% protection all the time.”  That’s not how vaccines work.  Vaccines work by reducing risk of infection for most people.  But vaccines, like seat belts and bulletproof vests and washing hands, are not perfect.  A small but important minority of people, due to the variety of human immune systems, fail to become immunized after receiving a shot.  Vaccines “work” because they do immunize most people — just not everyone.  That’s one reason why some vaccinated kids are still at risk from unvaccinated children.

Another reason why some vaccinated kids are still at risk from unvaccinated children is that vaccines don’t always provide perfect protection. Sometimes the protection afforded by a vaccine is to help the body fight off an infection, and thereby to make the infection tend to be lest serious. But that’s still just a tendency.  Vaccines’ efficacy can wear off over time, too.  It doesn’t make being vaccinated a bad idea, because some protection is better than none.  But the result of these imperfections of vaccines is that vaccinated kids are threatened by unvaccinated children carrying viruses and spreading them around.

That yellow wrist-picking woman asking the rhetorical question assumes that “vaccinated kids” are the only people at risk of being injured by unvaccinated children.  People who are very young, very old, or with health conditions that sap their immune systems become vulnerable to infection when exposed to unvaccinated carriers of disease.  Often, such people are so vulnerable to exposure to germs that it’s not even safe to vaccinate them. These immuno-suppressed people are sadly the most likely to be killed when exposed to unvaccinated carriers of disease.

Finally, the typical kid comes in contact with hundreds of other people. Even if the risk of an unvaccinated kid spreading an infection to a particular other person is small, the risk of an unvaccinated kid spreading the germs they carry to someone they know will be much higher because over many contacts, the risks add up.  When you fail to vaccinate your kid, your kid may be fine.  But your decision may result in the ravaging or death of a vulnerable baby, senior citizen, AIDS patient or person with cancer.

If you care about other people, if you care about your community, and if you recognize that not all protections are perfect, it makes really good sense to vaccinate your kids.  If you fail to do so knowing the effects of your failure, you demonstrate a callous disregard for the welfare of others.  Leaving healthy children unvaccinated is not just a health disaster; it is a moral failure as well.

    May I use parts of this to answer the very same question a friend posted this morning? Hers had a picture of a dinosaur though. 🙂

      Sure.

    A great article, Jim. I might have agreed with your friend on first impulse, but you state the case very well. I took the swine flu inoculation back in the seventies while battling mono, and 30 minutes later came down with it, eventually resulting in a blown heart valve. No surgery, just a long recovery, and a long memory of a bad experience with it. I still do wonder, though, if people who are vaccinated against a particular malady are still carriers of it, spreading it around the same as those who have not been vaccinated.

    One’s fears do not trump another’s Liberty. No one wants to be ill or spread illness, but we all have a Right to our own Liberty. If I choose not to insert foreign objects and God only knows what concoction into my body that is my Right.
    Your comparisons are way off. Driving under the influence most definitely puts others at risk. Shooting in a public square most definitely puts others at risk. Now, washing your hands may or may not put others at risk as with vaccines. That is why you use your Liberty and wash your own hands or receive a vaccination. To those who are vulnerable and fear illness, they must use their own Liberty to associate or not associate to control their risk. Not take away another’s Liberty.

      You are at liberty to refuse to vaccinate your kids in this country. You are also a massive asshole.

      1. Lydia says:

        An insult is not a way to support your views.You have the Liberty to do what you believe is best for you and your family. I hope you all live long and well.
        Vaccinations are not guaranteed to protect, I know of a seven months old infant that died from a vaccination.
        I use my Liberty to trust Christ whether vaccines are or are not taken.
        Proverbs 3:5,6
        Romans 8:28

          I’m not trying to change your mind, Lydia. I’m calling it as I see it. When people with your mindset refuse to vaccinate, people die needlessly. You’re free to do as you choose, but I am free to tell you that you are an ass.

    2. Nex says:

      Comment about liberties… so you would take the “liberty” to not vaccinate and thus put your child, a person in their own right, at a greatly increased risk of dying or being permanantly injured/ ill from a preventable desiese. I see that as no different than handing them a pinaple frag.

          Vaccines are also not guaranteed to kill. I am very sorry to hear about the 7 month old baby that died as a result of a vaccine. That is horrible and sad. It is also extremely rare. Your choice to not vaccinate does put others at risk though. It’s not just coming into direct contact with a (sick) unvaccinated person that can cause harm. Coming into contact with someone who previously came into contact with that person can spread the illness. Or your unvaccinated child could pick up the illness from another unvaccinated person. You put your child at risk to contract a life threatening disease, a greater risk than that of death by a vaccine. A tough choice to be sure. For me, the choice was clear. I vaccinated my kid for her health and the health of the planet. She survived just fine. She’s now 32 years old and still doing great!
