Which Part of the Herd Gets Protected by Community Immunity?
What if you aren’t vaccinated and protected?
Then you are protected by those who are!
“A situation in which a sufficient proportion of a population is immune to an infectious disease (through vaccination and/or prior illness) to make its spread from person to person unlikely. Even individuals not vaccinated (such as newborns and those with chronic illnesses) are offered some protection because the disease has little opportunity to spread within the community.”
CDC Vaccine Glossary of Terms
That’s what herd immunity is all about.
In a community, “the herd” includes those with immunity and those trying/needing to “hide in the herd:”
some people who are too young to be vaccinated or fully vaccinated
the people who’s vaccines didn’t work
anyone who can’t be vaccinated, because they have a medical contraindication
And it also includes those who are intentionally unvaccinated. The free-riders. Those who could be vaccinated, but simply choose not to, often because they have been scared by things they have heard or read about vaccines.
This all makes even more sense when you think about it as community immunity, the term that is more commonly used today.
Don’t want to think that you are in the herd?
The herd still protects you. At least it does if enough folks in the herd are vaccinated and protected.
“Whatever you think about Andrew Wakefield, the real villains of the MMR scandal are the media.”
Ben Goldacre on The MMR story that wasn’t
Believe it or not, there likely would not have been a big scare over the DPT vaccine in the 1970s and 80s or concerns about the MMR vaccine if the media hadn’t given so much attention to the anti-vaccine players involved.
False Balance About Vaccines at the Chicago Tribune
Folks in the media have learned their lesson though, right?
“Balance? There is no balance. There is mainstream, superstrong consensus about the value of vaccination, and on the other side … nothing else, since there is no other side. The media have made parents worry about vaccines in a lame effort to provide balance and all points of view.”
Arthur Caplan on There is no other side to the vaccine debate
Well, apparently not all of them…
Why would the Chicago Tribune devote nearly 20% of an article to a parent who is against vaccines, especially without correcting her misinformation?
Why haven’t they learned that spreading this kind of misinformation is what scares parents away from vaccinating and protecting their kids in the first place?
Are vaccinations about parent choice or public safety? That’s the title of the Chicago Tribune article. And maybe that’s why Illinois is among top 5 states for measles as debate heats up, the rest of the title…
Remember, a vaccine mandate that says you have to be vaccinated to attend daycare or school does not force anyone to get vaccinated. Folks still have a choice to not get vaccinated, even without access to non-medical vaccine exemptions, although they might not like what that choice entails, such as homeschooling or not being able to attend daycare or summer camp.
“One is morally free to use the vaccine regardless of its historical association with abortion. The reason is that the risk to public health, if one chooses not to vaccinate, outweighs the legitimate concern about the origins of the vaccine. This is especially important for parents, who have a moral obligation to protect the life and health of their children and those around them.”
The National Catholic Bioethics Center FAQ on the Use of Vaccines
Of course you should vaccinate them. But in getting them vaccinated and protected, you are not just protecting everyone else in the community. Getting vaccinated also protects your own child!
If the people they expose are too young to be vaccinated, too young to be fully vaccinated and protected, or anyone with a problem with their immune system, the results can be tragic.
Is it ethical that someone decides to skip or delay their child’s vaccines and then, through no fault of their own, someone else dies after getting exposed to this unvaccinated child when they develop measles or chicken pox?
Remember the measles outbreaks of 2015? In addition to the large Disney Land measles outbreak, 2015 was infamous for a smaller outbreak in Clallam County.
“The death of a Clallam County woman this spring was due to an undetected measles infection that was discovered at autopsy. The woman was most likely exposed to measles at a local medical facility during a recent outbreak in Clallam County. She was there at the same time as a person who later developed a rash and was contagious for measles. The woman had several other health conditions and was on medications that contributed to a suppressed immune system. She didn’t have some of the common symptoms of measles such as a rash, so the infection wasn’t discovered until after her death. The cause of death was pneumonia due to measles. This tragic situation illustrates the importance of immunizing as many people as possible to provide a high level of community protection against measles.”
Measles led to death of Clallam Co. woman
There were five measles cases in that 2015 Clallam County, Washington outbreak, including four who were not vaccinated. The outbreak cost at least $223,223 to contain and led to the death of a woman who just happened to be at a health clinic as one of the infected people.
Want to dismiss this case as being too rare to worry about? Just look at what is happening across Europe, with the rise in measles cases and measles deaths over the last few years.
Ethically, why should you vaccinate?
That’s easy, so that your kids don’t get a life-threatening vaccine-preventable disease. And so that they don’t expose others, potentially giving them a life-threatening disease that they are too young to be vaccinated against, couldn’t be vaccinated against because they had a true medical exemption, or were vaccinated against but are still susceptible to because they now have a problem with their immune system.
“It is UNETHICAL to expect me to sacrifice my child for yours—especially when I know that sacrifice won’t even stop the disease from spreading. It’s time for people to stop touting their “moral superiority and selflessness” when it comes to this topic; because if you really understood how this all works, there would be nothing for you to be proud of.”
Melissa Floyd (she apparently does a podcast with Dr. Bob)
Here is where the misinformed consent comes in and ethics go out the window:
And for the record, few of us think that we are morally superior to anyone else for vaccinating and protecting our kids. We just understand that many anti-vaccine folks are victims of their cognitive biases and need to do more research. And we know that it is UNETHICAL for parents to sacrifice their kids to anti-vaccine propaganda.
