(21,786 posts)if some unknown number of parents choose to not vaccinate, then vaccination rates will fall below the level that confers herd immunity (as they have in fact done in some places, where there have been epidemics).
DanTex
(20,709 posts)And more to the point, if 90% overestimates the coverage rate, that would make the numbers come out even more unfavorably for the vaccine, because it means that there are more unvaccinated individuals over whom the cases of measles are averaged.
Spider Jerusalem
(21,786 posts)That was after MMR had become standard. So that's more like what you can expect with more parents deciding "we don't need to vaccinate". Frankly, not vaccinating is stupid. The very low rate of vaccine-associated deaths and serious complications is much much lower than the death rate from measles. This is the same sort of fallacy that makes people think they're safer driving than flying.

During 1988 through 1990, California experienced its worst measles epidemic in more than a decade, with 16,400 reported cases, 3,390 hospital admissions, and 75 deaths.

NB that 75 deaths out of 16400 cases is a fatality rate of 0.46%/
DanTex
(20,709 posts)computed the measles fatality rate.
If you have a statistical argument that not vaccinating is a stupid individual decision, I'd like to hear it. The fact is, we live in a society where most people are vaccinated, and there are very low numbers of measles outbreaks. That's why you had to go back 25 years to find your anecdote. In this society, the numbers don't add up favorably to getting MMR. Unless my math is wrong. Please correct me if that's true.
It's true that as a society we are all better off with more immunized people. But that doesn't affect the individual cost-benefit analysis. You can say that not vaccinating is selfish, but in the status quo, it isn't stupid.
If you do a cost-benefit analysis for driving and flying, the kind I did in the OP, you will find that (per mile, not per hour), flying is much safer. I'm not sure what fallacy you are referring to. There's no herd immunity in flying.
Spider Jerusalem
(21,786 posts)Also I don't think you know what "anecdotal" means.
And not vaccinating is a stupid individual decision because society is made up of individuals. If a sufficient number of individuals make the decision not to vaccinate, then it's a problem for society as a whole.
DanTex
(20,709 posts)There is a distinction between what is good for an individual and what is good for society as a whole. If you can't grasp that, I'm not sure where we go from here.
Anecdotal means taking a single event or anecdote and trying to draw conclusions from it without looking at the larger statistical picture. Exactly what you are doing.
The rates of measles have been steady at about 100 per year over the last decade. There has been a recent spike, which I noted in the OP, can change the analysis. On the other hand, the fatality rate of 0.3% is probably high, so even at 600 per year, MMR is probably net negative for the individual.
onecaliberal
(36,594 posts)Mean death for someone else. If you want to live in society and put your kid in public school, the whole of society is affected. So NO it's not an individual decision when so many can be affected. This whole line of thinking is just asinine.
Spider Jerusalem
(21,786 posts)isn't necessarily going to be the fatality rate in a specific outbreak. In some, the rate may be zero; in others, more on the order of 0.4-0.5% rather than 0.3%. And I quite understand what an individual decision is. However individuals live in society, and as such have no right to make decisions that will endanger others. Choosing to drive drunk is also an individual decision, and we have laws against it for a good reason.
The fatality rate of measles being 0.3%, or even 0.1%, is still significantly higher than the rate of adverse reaction to the MMR vaccine ( 0.000001%). Therefore it's frankly stupid to suggest that MMR is a "net negative for the individual".

(36,925 posts)In the 1950's the urbanization rate was far lower than it is today. It also assumes zero benefit to the reduction of hospitalization, disabling permanent complications like deafness and brain injury, loss of school and work, etc.
DanTex
(20,709 posts)the endnote that the 0.3% fatality rate seems high, because it is so much higher than in the 1950s. If anything the lack of urbanization and access to hospitals should imply that the fatality rate would be higher in the 1950s than today. The 0.3% was from a study of ten or 15 years before 2000. I could use data from 2000 to the present, but of course in that case the fatality rate would be 0%.
You are right that I am only including fatalities as risk factors. If we include other outcomes, we have to do that both for the vaccine and for the disease. I find it odd that you listed non-fatal outcomes for measles but didn't complain that I didn't count non-fatal disabilities that resulted from the vaccine, including permanent complications, loss of work for the parent, hospital costs, etc.
You're welcome to do the full analysis for both, weighing all possible outcomes based on how bad they are.
Major Nikon
(36,925 posts)Because in essence you would be saying the MMR vaccine's effectiveness is a reason not to get it.
But regardless of what figure you come up with by pure speculation, comparing it to the complete bullshit figure from VAERS is still misleading and is easy enough to debunk by simply reading the disclaimer one has to click to acknowledge to get to the database in the first place. Very telling that.
When evaluating data from VAERS, it is important to note that for any reported event, no cause-and-effect relationship has been established. Reports of all possible associations between vaccines and adverse events (possible side effects) are filed in VAERS. Therefore, VAERS collects data on any adverse event following vaccination, be it coincidental or truly caused by a vaccine. The report of an adverse event to VAERS is not documentation that a vaccine caused the event.
VAERS data contains coincidental events and those truly caused by vaccines.
More than 10 million vaccines per year are given to children less than 1 year old, usually between 2 and 6 months of age. At this age, infants are at greatest risk for certain medical adverse events, including high fevers, seizures, and sudden infant death syndrome (SIDS). Some infants will experience these medical events shortly after a vaccination by coincidence.
These coincidences make it difficult to know whether a particular adverse event resulted from a medical condition or from a vaccination. Therefore, vaccine providers are encouraged to report all adverse events following vaccination, whether or not they believe the vaccination was the cause.

DanTex
(20,709 posts)Yes, in a sense, the MMR vaccine's effectiveness is the reason not to get it. Measles has been reduced to the infinitesmal extent that it is no longer personally beneficial to get it.
Yes, the VAERS data, like all data sources, is not perfect. It is likely that it contains some deaths that were not caused by vaccines, and it misses other deaths that were caused by vaccines.

(24,008 posts)or a WE society??
this is key to your post...
DanTex
(20,709 posts)At least not based on present statistics.
Still, if vaccinating isn't mandatory, I can't blame a parent too much for putting the life of their own child above the lives of others. People look out for their own family, it's human nature.
jehop61
(1,735 posts)You can't base it on a ten year timeline. Measles was thought to be eradicated during that time. Go back 40 or 50 yearswhen it was rampant. A friend contacted measles 40 years ago from her children. She was in the early stages of a pregnancy. Her child was born deaf and profoundly mentally disabled and is still being cared for in a state institution.
No ine is talking today about measles' effect on pregnancy. Vaccinate your children!
DanTex
(20,709 posts)Using 50-year old contraction rates would be a truly horrible way to make decisions about what to do in the present day. For today's decisions use today's numbers. If measles goes back to where it was 50 years ago, the numbers change, and so does the cost-benefit analysis.
marym625
(17,997 posts)On the mortality rate, the number of deaf and disabled with numbers prior to the vaccine. Because the if the "anti-vax idiots" continue and this movement grows, that's what you'll be looking at.
DanTex
(20,709 posts)Yes, it's a shortcut, and it doesn't capture all the harms. But if we're weighing all outcomes, including permanent disabilities short of death, we have to do the same with both measles and with MMR.
It's not a real look at the problem when you don't take on the consequences of measles coming back to pre-vaccination levels. If one kid is not vaccinated, and you compare to the risk of getting measles when all others are, of course the MMR risk is greater. When you have millions of kids not vaccinated, those numbers flip. So the numbers you post mean nothing.
DanTex
(20,709 posts)As a society, if vaccination rates drop, that's bad. But that's bad whether or not I decide personally to vaccinate.
If the argument is that people need to vaccinate for the good of society, be honest and make that argument. As per the status quo, the risks involved with vaccination are greater than the risks involved with non-vaccination. If the status quo changes, the comparative risks will change also.
marym625
(17,997 posts)It becomes not just protection of society but the individual. Because with every rate drop, the chances of your child contracting measles increases.
There's nothing dishonest about what I am saying. I'm done. Anti-vaccination idiots can't be reasoned with.
On edit: just adding - we live in a global society.
DanTex
(20,709 posts)the numbers will change and it will be beneficial for the individual to get the MMR vaccine. As others have pointed out, if you live in, say Sudan, then it is a very very good idea to get a measles shot.
But, right now, living in the US, an MMR vaccine causes more risk than it prevents. Getting a vaccine can be understood as an act of altruism, and refusing as an act of selfishness, but not of stupidity.

Do NOT hide this, jury.
DanTex
(20,709 posts)and an individual argument?
I.e. getting an MMR vaccine, based on present data, is more likely to kill you than save your life. That's an individual argument.
But, it is better for society as a whole for more people to be vaccinated, because it reduces transmission risk. That's a societal argument.
In this case the individual and societal cost-benefit analyses are at odds.

DanTex
(20,709 posts)Can you defend your anti-anti-vax position with logic or statistics, or is it just an emotional them-versus-us thing?
Dr Hobbitstein
(6,568 posts)those of us who are pro-science? You know, the rational thinkers who use data and not emotion to make decisions. Anti-vaxxers deserve shame. Their fears are based on junk science and unfounded claims. No matter how much you try and show them the truth, they ignore it.
Measles killed a few hundred thousand a year before the vaccine. Then there were the people who were injured from the disease. Blindness, paralysis, decreased mental function. The vaccine has caused less than 100 deaths in a 10 year time period. If we lose herd immunity (85-95% required for measles), we will see those deaths again. Your whole premise is flawed.
I did find an anti-vaxxer/woo/CT site trying to make the same exact points as you, though.

Get your brain out of the fog and start treating the world as if it's something OTHER than a system of nebulous symbols the public manipulation of which earns you imaginary debatey points.

(20,709 posts)What's up with the emotional stuff on this issue. Even if I'm wrong, we're talking about a disease that has killed zero people in ten years. All of a sudden I post some statistics and now I'm Satan. Odd.
Bluenorthwest
(45,319 posts)"Britain went through wave after wave of outbreaks of measles and mumps after the now-discredited reports by Andrew Wakefield in the 1990s linking measles, mumps and rubella (MMR) vaccines with autism.
Vaccination rates in Britain plunged to 85 percent and measles cases rose: 1,000 cases 2011, 1,900 in 2012 and again in 2013. A mumps epidemic made more than 56,000 Britons sick in 2004-2005. Now vaccination rates are back up to 95 percent and just 137 cases were reported in Britain in 2014. Measles cases were mostly among children aged 10 to 19 who missed the normal vaccination schedule during the vaccine scare years, Read said."

Long debunked. In fact, your post is irrational and dangerous.
Your reliance upon VAERS data basically makes your entire argument BUNK!
Guide to Interpreting VAERS Case Report Information
When evaluating data from VAERS, it is important to note that for any reported event, no cause-and-effect relationship has been established. Reports of all possible associations between vaccines and adverse events (possible side effects) are filed in VAERS. Therefore, VAERS collects data on any adverse event following vaccination, be it coincidental or truly caused by a vaccine. The report of an adverse event to VAERS is not documentation that a vaccine caused the event.
VAERS data contains coincidental events and those truly caused by vaccines.
More than 10 million vaccines per year are given to children less than 1 year old, usually between 2 and 6 months of age. At this age, infants are at greatest risk for certain medical adverse events, including high fevers, seizures, and sudden infant death syndrome (SIDS). Some infants will experience these medical events shortly after a vaccination by coincidence.
These coincidences make it difficult to know whether a particular adverse event resulted from a medical condition or from a vaccination. Therefore, vaccine providers are encouraged to report all adverse events following vaccination, whether or not they believe the vaccination was the cause.
Please read the following statement on the limits of VAERS data. You MUST click on the box below to access the VAERS database.
When reviewing data from VAERS, please keep in mind the following limitations:
VAERS is a passive reporting system, meaning that reports about adverse events are not automatically collected, but require a report to be filed to VAERS. VAERS reports can be submitted voluntarily by anyone, including healthcare providers, patients, or family members. Reports vary in quality and completeness. They often lack details and sometimes can have information that contains errors.
"Underreporting" is one of the main limitations of passive surveillance systems, including VAERS. The term, underreporting refers to the fact that VAERS receives reports for only a small fraction of actual adverse events. The degree of underreporting varies widely. As an example, a great many of the millions of vaccinations administered each year by injection cause soreness, but relatively few of these episodes lead to a VAERS report. Physicians and patients understand that minor side effects of vaccinations often include this kind of discomfort, as well as low fevers. On the other hand, more serious and unexpected medical events are probably more likely to be reported than minor ones, especially when they occur soon after vaccination, even if they may be coincidental and related to other causes.
A report to VAERS generally does not prove that the identified vaccine(s) caused the adverse event described. It only confirms that the reported event occurred sometime after vaccine was given. No proof that the event was caused by the vaccine is required in order for VAERS to accept the report. VAERS accepts all reports without judging whether the event was caused by the vaccine.
DISCLAIMER: Please note that VAERS staff follow-up on all serious and other selected adverse event reports to obtain additional medical, laboratory, and/or autopsy records to help understand the concern raised. However, in general coding terms in VAERS do not change based on the information received during the follow-up process. VAERS data should be used with caution as numbers and conditions do not reflect data collected during follow-up. Note that the inclusion of events in VAERS data does not imply causality.
