ScienceDaily (May 20, 2009) — The inactivated flu vaccine does not appear to be effective in preventing influenza-related hospitalizations in children, especially the ones with asthma. In fact, children who get the flu vaccine are more at risk for hospitalization than their peers who do not get the vaccine, according to new research that will be presented on May 19, at the 105th International Conference of the American Thoracic Society in San Diego.
Flu vaccine (trivalent inactivated flu vaccine—TIV) has unknown effects on asthmatics.
“The concerns that vaccination maybe associated with asthma exacerbations have been disproved with multiple studies in the past, but the vaccine’s effectiveness has not been well-established,” said Avni Joshi, M.D., of the Mayo Clinic in Rochester, MN. “This study was aimed at evaluating the effectiveness of the TIV in children overall, as well as the children with asthma, to prevent influenza-related hospitalization.”
The CDC’s Advisory Committee on Immunization Practices (ACIP) and the American Academy of Pediatrics (AAP) recommend annual influenza vaccination for all children aged six months to 18 years. The National Asthma Education and Prevention Program (3rd revision) also recommends annual flu vaccination of asthmatic children older than six months.
In order to determine whether the vaccine was effective in reducing the number of hospitalizations that all children, and especially the ones with asthma, faced over eight consecutive flu seasons, the researchers conducted a cohort study of 263 children who were evaluated at the Mayo Clinic in Minnesota from six months to 18 years of age, each of whom had had laboratory-confirmed influenza between 1996 to 2006. The investigators determined who had and had not received the flu vaccine, their asthma status and who did and did not require hospitalization. Records were reviewed for each subject with influenza-related illness for flu vaccination preceding the illness and hospitalization during that illness.
They found that children who had received the flu vaccine had three times the risk of hospitalization, as compared to children who had not received the vaccine. In asthmatic children, there was a significantly higher risk of hospitalization in subjects who received the TIV, as compared to those who did not (p= 0.006). But no other measured factors—such as insurance plans or severity of asthma—appeared to affect risk of hospitalization.
“While these findings do raise questions about the efficacy of the vaccine, they do not in fact implicate it as a cause of hospitalizations,” said Dr. Joshi. “More studies are needed to assess not only the immunogenicity, but also the efficacy of different influenza vaccines in asthmatic subjects.”

The landscape of children’s health has changed. If you have any doubt whatsoever, ask your grandmother. Did she have friends juggling breast cancer and play dates? What about autism and allergies? ADHD and diabetes?
And while there were other things that they worried about, as parents today, we sit beside each other on the sidelines of soccer fields, in concert recitals or in the pews at church, and with few words spoken, we understand that things have changed.
Today, 46 kids are diagnosed with cancer every day. It is the leading cause of death by disease in children under the age of fifteen. Diabetes, obesity, asthma and food allergies are a tsunami of conditions raining down on the health of our children. And autism now impacts 1 in 88 American children.
Our grandmothers weren’t navigating these statistics. We know that it hasn’t always been this way. And we see firsthand how hard it can be, as we share the heartache of a friend, witness the grief of a sister or help a neighbor struggling with the cost of care. We say our prayers at night, grateful for the blessings we have received and mindful of how quickly things can change.
Our children have earned the title of Generation Rx because of how pervasive these conditions have become. The number of US kids with autism is up 78% reports the CDC, impacting 1 in 54 little boys, while 1 in 3 is overweight or obese, triple the rate of 1963, reports the American Heart Association, and 46 kids are diagnosed with cancer and 1,500 Americans – moms, dad, sisters, brothers, children – die from cancer every single day.
It didn’t used to be this way. And as this landscape of health has changed so quickly in such a short time, it begs the question: Why? Why have our families become so allergic? Autistic? Diabetic? Cancer stricken?
Since when did the landscape of childhood feel like a landmine of disease?
A lot of theories are out there, enough to cause doubt and confusion, but mounting scientific evidence, from the President’s Cancer Panel to the American Academy of Pediatrics, urges us to protect the health of our children by reducing our exposure to environmental toxins, especially those now found in and on our food.
With the President’s Cancer Panel and Stanford University urging pregnant moms and those with children to reduce their exposure to artificial ingredients now found in our food supply (things like artificial growth hormones in dairy, weed and pest killers used so frequently on our fresh produce as well as other artificial ingredients), we find ourselves reading labels in grocery store aisles – no longer just for fat and sugar content, but also for the list of allergens, artificial colors or genetically modified ingredients or any indication of the manufactured chemicals that they may contain.
And while the task can be overwhelming, we do it anyway for the love of our families. We find the strength, tenacity and courage to continue to move forward, asking questions, researching and reading, trying to do everything we can to reverse this tidal wave of disease.
And we are not alone. Thankfully, more corporations in the traditional food sector and those in the organic industry are doing what they can to help us. Some have been doing it for a long time, others are just beginning to make change. But the important thing is this: we are all doing what we can, where we are, with what we have, recognizing that the health of our country depends on the health of our children. Because while our children may only represent 30% of the population, they are 100% of our future.
So we have a choice: to let their health conditions bring us to our knees or bring us to our feet.
And when we decide to stand, we do so out of love, knowing that we do not stand alone. Millions of citizens in countries around the world stood for their right to know what is in their food, and now, millions of Americans who share this deep concern are doing the same.
A corporation will always have the right to make a profit, but Americans should also have the right to know what we are eating, so that together, leveraging this collective information and insight, we can protect the health of our country.
