When the vaccine arguments are hot and furious, a frequent insult is: “You don’t understand the science!” The confusion in this case doesn’t arise from ignorance of science, but from ignorance of history. The people who think that vaccines saved millions of children from death see the story like this:
Childhood illnesses run uncontrolled through the population leaving dead bodies in every house. Parents are in despair. Brave doctor cooks up a vaccine, the disease stops dead, and all children come through to a healthy adulthood. Read more
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
Vaccine Myths, Round Two
Filed under: Parents' Pages, Vaccine Myths, Vaccine Science, Vaccine/Disease Analysis
Introduction: A while back, we explored some common anti-vax myths. Because in the great vaccine debates, the myths tend to outnumber the facts, we’ve decided to begin a multipart series dispelling some of the mythologies people argue over which preclude productive discussions over real issues. Below, you will find the facts behind two more common vaccine myths: herd immunity, and whether or not vaccines are profitable to pharmaceutical companies.
Myth: herd immunity isn’t real, and all the vaccine preventable diseases were declining in incidence prevaccine
Reality: vaccine induced herd immunity is a real phenomenon, and the incidences of the “diseases of childhood” (measles and mumps, for example) averaged out to be constant in the prevaccine era.
Here’s a chart showing the incidence of measles from 1912 till 1960.
Although the “death rate per cases” dropped an amazing amount, the same number of cases were happening per year on average. Read more
Prevnar IS Safe – Have a Look at the Studies!
In November of 2008, a report was published about a halted vaccine trial in India. Here is an excerpt which can be found on Livemint :
New Delhi: Patient trials of an advanced pneumonia vaccine by the domestic unit of US drug giant Wyeth Inc. have been suspended by India’s drug quality regulator after the death of an infant on whom the vaccine was tested in a trial in Bangalore.
The child had a pre-existing cardiac disorder. Indian drug rules prohibit testing on human subjects with such conditions without the prior approval of the drugs controller general of India (DCGI), the drugs quality regulator.
Indian authorities said that the trial was stopped because:
“The baby was suffering from a cardiac abnormality and should not have been included in the trial at all. It seems that the ‘inclusion-exclusion’ criteria protocol has not been adhered to by the investigator,” said Surinder Singh, drugs controller general. “We have suspended all further trials across the country.”
Vaccines? Safe. Parents? Dangerous.
Lately I’ve been noticing an increasing number of journal articles, blog articles and opinion pieces on a terrible problem: Parents have questions about vaccines.
You would have to look far and wide to find anyone who thinks that these questions are valid and should be taken seriously. Common explanations are:
1) It is all about the parents who think they are really smart.
2) It is all about the parents who are very stupid and read stuff on the Internet.
3) It is all about the bad stuff on the Internet which is deceiving the parents who aren’t very smart and who think they are smarter than doctors. And infinite variations on this theme, which is really one argument…and the real argument is (drum roll)…vaccines are perfect and parents are the problem.
Being called stupid dupes hasn’t worked to shut up the parents with questions. Perhaps this is not a good strategy?
I’m sure you’ve noticed that many articles and blogs offer comment options to the public. If you are following the vaccine related discussions you’ll have noticed that there is a coterie of passionate vaccine defenders who pop up in every such public discussion. These vaccine defenders are fighting for the good of the vaccine program with everything they’ve got.
Oddly, however, the number of parents with questions seems to be increasing. Perhaps the vaccine defenders need to reconsider their approach. Read more
Does the Inactivated Influenza Vaccine Even Work In the Recommended Age Bracket?
Filed under: News, Parents' Pages, Vaccine Science, Vaccine/Disease Analysis, WHO Watch
It’s that time of year again! Having spent last summer consulting the avian set on what’s hot in influenza, the pharmaceutical company has whipped up a fresh batch of flu vaccine, and now they need to move the merchandise! Fortunately, the CDC is happy to help with sales, by expanding the recommendation to ever more age groups. The Advisory Committee on Immunization Policy currently recommends the vaccine for all children aged 6 months to eighteen years. There is just one slight issue that might concern some parents. Peer-reviewed research in The Archives of Pediatric and Adolescent Medicine, Vol. 162 No. 10, October 2008,1 demonstrates that the vaccine is not effective under age 5!
An inherent assumption of expanded vaccination recommendations is that the vaccine is efficacious in preventing clinical influenza disease. Although studies have documented immune responses following 2 doses of inactivated influenza vaccine as well as vaccine efficacy for culture-confirmed disease in randomized clinical trials, surprisingly little information exists regarding influenza vaccine effectiveness (VE) among young children receiving vaccine in routine health care settings.
Merck staph vaccine enters phase II

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
