Myths 3.2 Chickenpox “the disease can be severe”
Filed under: CDC Watch, Parents' Pages, Vaccine Myths, Vaccine/Disease Analysis
Parents who take their children to chicken pox parties have forgotten how devastating this childhood disease can be according to vaccination experts:
“What happens if you bring your child to a chicken pox party and they’re the one in 10 who has a complication and is hospitalized?” said Dr. Jane Zucker, head of the city Health Department’s immunizations bureau.
We went back to 1951, when chickenpox afflicted millions of children every year in the U.S. to see if complications and hospitalization from chickenpox were common:
In general, chickenpox is a disease of young children and in them it usually runs an uneventful, if uncomfortable, course without leaving behind it any permanent bad effects. In very rare instances, a case of encephalitis or inflammation of the brain may occur after chickenpox, causing such symptoms as sleepiness, stiff neck, convulsions, coma, and even death.
Ordinarily, however, chickenpox is a mild though highly contagious disease…
This view of chickenpox as mild continued to exist in the U.S. for many years as this two part video snippet illustrates. Read more
Vaccine Myths 3.1: The Scourge of Childhood
Filed under: CDC Watch, Parents' Pages, Vaccine Myths, Vaccine/Disease Analysis
“…young parents of today do not remember…”
In 1974 the St. Petersburg Times wrote:
So many people are neglecting to get immunity shots that doctors fear the seven one-time scourges of childhood–polio, mumps, measles, rubella, diphtheria, lockjaw and whooping cough–may strike American communities again.
However, just six years earlier, in 1968, newspaper stories said things like this:
Although mumps is a relatively mild childhood disease, it can cause sterility when it strikes adult males.
At that time the recommendation was to give the recently developed shots to boys if they hadn’t had the mumps by the time they hit adolescence. Read more
“Just because you need a third dose doesn’t mean the two dose schedule is having issues or anything”
Filed under: CDC Watch, News, Opinion, Parents' Pages, Vaccine/Disease Analysis
Because of continued spread, health authorities working with communities in Orange County are giving schoolchildren a third dose of the MMR vaccine. Gallagher says it will be two or three months before it’s known whether the effort succeeded.
Why do they need a third dose?
The infections happened despite high coverage with the measles-mumps-rubella (MMR) vaccine. Among patients ages 7 to 18 — the age group that had the most cases — 85% of patients had received the two recommended MMR vaccine doses.
This doesn’t mean the MMR vaccine isn’t working, says epidemiologist Kathleen Gallagher, DSc, MPH, the CDC’s team leader for measles, mumps, and rubella.
“Two doses of mumps vaccine is believed to be 90% to 95% effective,” Gallagher tells WebMD. “But that means people can still get mumps. If the vaccine is 90% effective and 100 people are exposed to mumps, 10 will get the disease.”
If we imagine that mumps is being sprinkled from the sky and spread evenly throughout the population, then yes, one out of ten vaccinated people would catch mumps if the vaccine was, indeed, 90% effective, or one out of twenty if it were 95% effective. But if the vaccine creates “herd immunity” then the disease shouldn’t be able to jump from vaccinated person to vaccinated person to vaccinated person. Read more
Where Do They Find These Scary Statistics III – Let’s Make a Few Assumptions – Hepatitis B
Filed under: CDC Watch, Vaccine Science, Vaccine/Disease Analysis
Parents have questions about the risk-benefit equation of the Hepatitis B vaccine. It is possible for a parent to be quite certain that their infant is not at risk of prenatal or birth exposure to this disease. The risk factors for exposure during infancy, early childhood, and the elementary school years can be reasonably well assessed on an individual basis. Read more
Health Marketing, Risk Communication, and the Media
Remember the Great Influenza Vaccine Shortage a few years back?
Panic swept the nation after the FDA rejected many European flu shots because of possible contamination during manufacturing. What was left was rationed according to age and risk factors, and the public could be seen every night on the news waiting in long lines to get the remaining doses.
Now, setting aside for the moment the ongoing questions regarding the usefulness of flu shots in any age group, especially the elderly, one might come to wonder what has changed in recent years to bring about this new terror regarding influenza.
The answer, as outlandish and implausible as it might sound, is that this fear has been manufactured and marketed by the people in public health. Read more

Where Do They Find These Scary Statistics?

Dr. Gerberding of the CDC
[Series Links: Part II, Part III]
Remember Hannah Poling? The head of the CDC, dressed in a very nice pink suit, appeared on TV and discussed Hannah’s case. In one of her appearances she said something like this: “Vaccines prevent 33,000 deaths a year in the United States.” Just to make sure I had the statement right, I searched for the phrase and found it again, from CNN, this time in print.
Today, through immunizations given in the first two years of life, we can protect children from 16 diseases, preventing 33,000 deaths and 14 million illnesses per year.
A few searches made it clear that this is a very popular statistic. A variety of news stories included the information that vaccines prevent 33,000 deaths a year in the United States. This is an interesting number to anyone who knows a bit about the history of infectious diseases. I decided to dig deeper.
My next find was this chart, which is on a the web-site of an organization called Every Child by Two. The chart provides morbidity (incidence) and mortality (deaths) for each disease. How in the world would someone be able to calculate (for example) the exact number of cases of diphtheria which would occur and the exact number of deaths which would follow? Amazing! There must be some truly extraordinary scientific research underlying these numbers, don’t you think? Read more
For the Good of the Herd
Filed under: CDC Watch, Parents' Pages, Vaccine/Disease Analysis
In an era where CDC experts are saying, “Just line up for Gardasil, and you’ll have a 70% reduced chance of getting cancer”, are parents asking any critical questions about the crystal ball gazing abilities of these experts now and in the past? Why is there talk of adding a third MMR vaccine into the childhood schedule, and also putting it into adult vaccination programs as regular boosters?
Will most people just roll up their sleeve, assuming the new ideas will have the good outcome the CDC will predict?
Most of those people won’t know, that in 1967, the CDC said: *
For centuries the measles virus has maintained a remarkably stable ecological relationship with man. The clinical disease is a characteristic syndrome of notable constancy and only moderate severity. Complications are infrequent, and, with adequate medical care, fatality is rare.
Effective use of these vaccines during the coming winter and spring should insure the eradication of measles from the United States in 1967. Read more
Vaccine Information Statements For Dummies
Before any doctor gives your baby vaccines, you should be given Vaccination Information Sheets (VISs) to read.
Developed by the CDC, they inform vaccine recipients, their parents or legal representative, about the benefits and risks of vaccines. (1) Federal Law requires their use. This is a result of the National Childhood Vaccine Injury Act of 1986, 42 U.S.C. 300aa-26. (1) Before 1986, parents didn’t have any right to printed information about vaccines.
VISs sound like a good system. Parents get concise and easy to understand information on a vaccine’s risks and benefits so they can make an informed decision.
Is that really how it works? Let’s examine the nuts and bolts of VISs.

Pertussis: Yo-Yo Stats
Previous CDC articles: Stupid , Measles
Pertussis, popularly known as Whooping Cough, is an illness that ranges from mild to very dangerous. The levels of incidence seem to be a bit of a mystery. One department of the CDC claims that the vaccine is doing a great job of protecting us from death-dealing outbreaks of pertussis while another department of the same organization claims that pertussis is endemic in the United States. Follow me down the bureaucratic rabbit hole, as we try to discover the truth about The Cough!
