Shaken Faith in the Flu Vaccine?
They account for some of the great victories in the history of public health, but vaccines have had a rough time of it lately.
First there was the federal government's agreement in March to compensate an Atlanta family whose daughter developed autism after receiving a set of routine childhood shots. That decision fueled ongoing speculation that childhood vaccines can cause autism.
Then we learned that the mumps vaccine turns out not always to provide complete and lasting protection against this potentially dangerous disease -- one many of us figured we didn't have to worry about any more.
And now this: The U.S. Centers for Disease Control and Prevention issued a report Friday saying that this year's influenza vaccine was mismatched to the strains of flu that ended up circulating this year, a situation that likely led to a higher-than-usual incidence of the illness and related deaths -- even among people who had been vaccinated.
Public health officials express concern that the vaccine's poor performance this year may discourage folks from getting vaccinated next year.
Who could blame folks for being a bit discouraged?
Flu-vaccine production is a long process, so scientists need to figure out nearly a year ahead of time which three strains of flu virus to protect against in the coming flu season. (Efforts are underway to develop a universal influenza vaccine that would protect against all strains, but despite promising recent developments, we're not quite there yet.)
This year they guessed wrong. For the 2008-2009 season, they've taken the unusual step of starting from scratch: None of the three strains next year's vaccine will protect against is included in the current season's vaccine.
But there's no telling whether that gamble will pay off.
The risk is that parents will remember the few horror stories (the 14 children who did get vaccinated this season, only to die of influenza after all) and overlook the massive benefits vaccination has -- and can continue -- to bring.
Look at the bigger picture, though: While some people in privileged Western countries have become skittish about vaccinating their kids, those who really know the dangers of contagious illness welcome these preventive measures: 62 million children, adults and elderly people in 44 countries and territories throughout the Western Hemisphere are expected to receive free vaccines against leading infectious diseases as part of the sixth annual Vaccination Week in the Americas, which is taking place this week. Read more here.
I'll be dragging my kids off to the pediatrician this fall, as I have done every year.
And keeping my fingers crossed. Not because I'm worried they'll be hurt by the vaccine, but because I hope that it will target the right strains of flu.
P.S. to the reader who commented on my April 9 blog about vaccine safety: While it's true that some influenza vaccine does still contain the ethylmercury-containing preservative thimerosal (which some suspect may cause neurological problems, including autism), the CDC notes that manufacturers are working to phase it out. Read more about thimerosal here. Thanks for writing!

Me again.
We are doing all the vaccinations because they are required for school (public and private schools). You can get a religous exemption which is usually by the city/county government.
Spreading out the vaccines is expensive. The individual vaccines (such as MMR) and extra doctor visits are usually not covered by insurance.

I vaccinated my children because I did not want them to have the risk of contacting preventable childhood diseases.
We knew a teen at church who although vaccinated, contracted whooping cough. She coughed so hard the blood vessels in her eyes burst and she missed nearly a semester of school. Why would I want that to happen to my children?
My husband and I got our flu shots this year, and we didn't get the flu. It's my belief that the presence of a vaccinated community keeps incidents of the flu to a minimum, even if the vaccination isn't perfectly adjusted to the current strains. I have better things to do with my time than spent it sick.

I find it interesting that nobody follows up on what country produced this years flu vacine. I doubt that it was the U.S.

Note that the incidence of measles is way up in the UK (and one boy has died), as a result of scare tactics against the MMR vaccine (which never contained mercury).

There are compelling reasons to be vaccinated. The chicken pox vaccine was not developed for working parents! Children who are immunosuppressed can die from this illness. Themirisol has no place in vaccinations and it is best if the mmr is broken up. It is a cost and time savings factor for Drs. to give it this way.
The flu vaccine was not very effective this year but that does not mean that no one should get it next year. Medicine is not perfect but it is pretty darn good.

1. You probably get a larger dose of mercury from tuna fish suchi than a dose of a thimerisol containing vaccine.
2. When a substantial percent of a population is vaccinated against a disease with a human-human mode of transmission, the percent of unvaccinated individuals developing the disease decreases significantly. That's why (with polio vaccine)unvaccinated individuals or the small percent in whom the vaccine did not "take" (one never knows!) have an almost zero risk of developing polio, as long as they stay in the U.S. Always recommended to re-vaccinate against polio when traveling to an area where it is still endemic!
3. Flu vaccines are produced in the U.S. The CDC and the pharmaceutical companies producing the flu vaccine miss their antigenic targets less than 10% of the time (the last significant miss was winter 1995-96, and I did get nailed). You wish you could do as well in Las Vegas or the stock market!

A survey was conducted to establish the
diagnostic accuracy of doctors in relation to patients who the doctors thought had measles.
Every time the doctor identified measles he was asked to take a swab and send it to the laboratory.
Of 700 doctors taking the test how many do you think got it right?
If you guessed 70 or 10% you got it right.
So 90% got it wrong?
The point being that peoples perceptions of what is true is so often based on statistics which they read in the newspapers or on television, and is put out by some group with a special interest in
promoting a point of view which supports their marketing efforts.
To overcome this bias it is important to ask who is doing the study of say measles
and why. Have they a financial interest.
Are you getting the whole story.
As shown last week Merck "made up" their own studies and had their own in house doctors sign them as though they had done the research as reported in the influential
medical journal,JAMA. who were reporting on
information uncovered by investigators
in the Vioxx case where the company paid out $4.85 billion to people who were damaged by that drug.
Just because some authority says something is true, be that the government, the Pharmacuetical Cos, or doctors, does not mean they are correct or are stating the
truth in whole or in part.
A healthy diet, exercise, and good family
and work relationships is the best protection against any virus.
Unfortunately the junk food that many eat
today is a recipe for a lifetime of ill health both mental and physical and a guarantee of obesity, high blood pressure and diabetes.

I have 2 year old and 5 year boys. We have been very slow to vaccinate, including breaking up the M-M-R into separate shots. They haven't gotten the flu shot yet and they don't have a compelling reason to get it. Their immune systems are robust and they get sick less than most of their friends.
My "faith" is vaccines was shaken long ago after learning about why some vaccines are required (chicken pox is required to cut down on sick days by parents), why multiple vaccines are given at one time (because poorer kids go to the doctor less often so give them as many as possible) and why mercury was removed from most vaccines (it's fine, no problems, don't worry but we're removing it anyway, please don't sue us).
