Consider religion: a system invoking various things taken on faith, together with vaguely related rules for behavior. Historically, people who violated the rules were punished by society, society acting as enforcers for the possibly-present invisible forces believed to exist. However there have always
been skeptics, who either disbelieve the various things and so the linked rules, or dislike the rules, or distrust the motives of the religious authorities who enforce the rules.
With this definition, many aspects of western medicine require some religion. Various statements are made with authority, followed by rules for behavior. Societal punishments for violating these rules have become less severe but still exist: try smoking on a playground.
Consider now vaccination. Parents are told that scary monsters (measles, whooping cough) will get their kids if the kids are not vaccinated. Some parents are drunk and not paying attention, some may disbelieve in the scary monsters but I think most nonvaccinators just dislike being told what to do: they distrust the authorities and so do not vaccinate their kids. Then the scary monsters get the kids and then go on to kill any tiny babies the carrier kids are exposed to.
How to divorce vaccination from authority? I propose vaccines be made over the counter. People could use them to treat arthritis or hyperactivity, or rub them on as a balm. Skeptical parents could use them as they saw fit, on themselves, kids, or whatever. The sort of parents who care for their kids but do not vaccinate out of distrust may be more likely to vaccinate when they personally can decide the where, how, when and how much. When it comes to childhood disease vaccines, anything is better than nothing.
The only problem is the needle aspect, which I will work on.

Where's your sense of Darwinian loyalty? Stupid parents >>
non-vaccination >> fewer stupid children >> fewer stupid
parents. |
|
| |
[MB] Wrong, I think. If the smart parents' children are in
the majority, the stupid parents' children benefit from
herd immunity, while avoiding whatever low risk of
complications the vaccine entails. So the stupidity gene
enjoys a survival advantage up to some equilibrium
frequency. Hence: in the long run, non-vaccination
doesn't reduce the number of stupid people, and, in the
short run. may even increase it, depending on starting
conditions. |
|
| |
(Of course the *really* smart parents will switch strategies
according to whether the current percentage of stupid
people is above or below the equilibrium point.) |
|
| |
False logic, I think. Herd immunity protects everyone to
some degree, but vaccination protects completely. |
|
| |
For example, suppose you have a community of 100 smart
and 100 dumb people, and a disease infects 10% of them at
random; that's 10 smart and 10 dumb people infected. |
|
| |
Now the smart people get vaccinated (50% of all people),
and you might reasonably expect the disease to decline by
75%, so that only 5 people get infected. But those 5
people will all be dumb. |
|
| |
//vaccination protects completely//
There's where your assumptions differ from mine. In this
model, death-prior-to-reproducing from a vaccinatable
disease has the same effect (no progeny) as death-prior-
to-reproducing from a complication of vaccination. You're
assuming the latter is zero, and I'm not (//whatever risk of
complications the vaccine entails//). (We're both
assuming vaccination protects completly against disease,
which is probably unrealistic.) |
|
| |
Under some simple assumptions, I think the stable ratio of
smart to dumb people will be exactly the ratio between
risk of dying from disease (given unvaccinated and given
herd immunity) and risk of
dying from vaccination (given vaccinated). The effects of
differential fertility among smart & dumb people are left
as an exercise to the reader. |
|
| |
/make vaccines over the counter/ |
|
| |
In the future, it may very well be like this - deposit a fluid sample, an get an auto vaccine while you wait.
A bit like taking a colour sample, and getting some paint mixed. |
|
| |
//whatever risk of complications the vaccine entails// |
|
| |
Yes, you're right if there are significant risks from the
vaccine, and if the non-immunised people are in the
extreme minority. In this case, the risk from the vaccine
would outweigh the very small risk of disease in a mostly-
vaccinated population. |
|
| |
However, the majority of vaccines are so safe that the
level of herd immunity has to be overwhelming to balance
the risk of not taking the vaccine. |
|
| |
Given that some diseases have animal reservoirs, and given
that many children will mix with overseas visitors who may
not be vaccinated, there are very few cases where it's not
worth getting vaccinated. |
|
| |
Having said all that, there's reason not to make vaccines
more readily accessible, if a safe delivery system exists. |
|
| |
OPV would be practical OTC now. Others would need to be altered in such a way that they would in any case become more popular even if not OTC. Having said that, i think this is a good idea. |
|
| |
as well as parents that wouldn't bother getting their offspring vaccinated, there would also be those who would drag the kids into the drugstore once a month just to make sure. Currently vaccinations do require some, if even minimal, supervision from a medical authority. |
|
| |
As well, some have rather short shelf-lifes. |

If you strike it down, it will become more powerful than you can ever imagine... |

We consider that a "Masque of the Red Death" <link> apporach may be more appropriate. |
