Close to Home: It Can Happen To You

Embarrassed and shocked are the feelings that I am experiencing right now.  In what seems to be the never ending story of my daughter’s “stomach bug,” I have more news; news that is a little embarrassing to admit, particularly considering that I write this blog.  I received a call last week from our pediatrician telling me that not only did lab results indicate that my daughter’s hospitalization was due to rotavirus, but that she never received the recommended vaccinations she needed to protect her from it.  I was beyond confused.  What do you mean she wasn’t vaccinated?  I have never missed an appointment so how was this possible?  It turns out that the practice our doctor works in only recently started carrying rotavirus vaccines in the office.  Our doctor explained that at a child’s two-month well-visit she always informed patients that the vaccine was not provided in the office, but gave a list of locations where the vaccinations (which are administered in three doses at two, four, and six months) were available.   In all the hustle and bustle of a doctor’s appointment I honestly don’t remember having this conversation.  Looking back, my son, who was also never vaccinated, contracted the illness first and within a day had passed it on to my daughter resulting in her four day hospitalization.

Right now I am truly embarrassed; embarrassed that I have a passion to spread the word about the importance of vaccine-preventable diseases and yet I failed to make sure that my own children received all of their recommended vaccinations.  I am shocked; shocked that this actually happened to my family.  No one ever anticipates being the one whose daughter, cousin, uncle, or mother contracts a serious illness, certainly not one that is preventable.  I am testimony to the fact that vaccine-preventable diseases affect the unprotected.

So why am I sharing this information with you when in reality, I could simply push it under the rug and pretend like it never happened?  I share it for two reasons.  First, because I realize now more than ever that we are the most powerful advocates for not only our own personal health but for the health of our families.  The relationship between a patient and a physician should be an equal partnership, and a partnership only works if both parties are on the same page.  In regard to vaccinations, do your research.  Know what and when vaccinations are recommended by the Centers for Disease Control (CDC) and if those guidelines are not being followed, be proactive in order to ensure that your family is protected from a long list of vaccine-preventable diseases.  I did not realize that my children were not being administered a recommended vaccination.  I simply assumed they were and my children paid the price.  Secondly, if sharing my experience saves another family from going through the same experience, I gladly welcome the opportunity.  The cases of pertussis (“whooping cough”), measles, and rotavirus that you hear about on the news don’t just happen to “other people.”  They can happen to you and your family and have serious, if not life-threatening consequences.  Take charge of your health and the health of those you love.

Accessing Global Experience and Generational Memory of Epidemics to Promote Vaccination: What Each of Us Can Do Every Day

When I was growing up, the calling I felt to become a physician was almost inseparable from the desire to work internationally. I’ve been lucky to have had many opportunities to work, study and serve overseas and have always enjoyed being a doctor in the developing world. My international health work has often afforded me indispensable learning experiences, at once uplifting and humbling. But sometimes, the experiences can be unpleasant – and I don’t mean because of the rough conditions, or even the many dangers of traveling to remote areas of the globe, but because these experiences bring into sharp relief how much we have here in the US comparatively, and perhaps how little we appreciate and utilize those many gifts.

One of the more embarrassing moments I can recall occurred during my first trip to Bolivia some years ago. I was with a group of Curamericas volunteers who were serving in Montero in the rural lowlands of Bolivia, and we had the opportunity to visit Nur University in nearby Santa Cruz. Nur is renowned for its innovative programs and for graduates who are dedicated to public service. We were on a tour of the main building when a group of Public Health students heard we were on campus and asked to meet with us. After a short dialogue during which we answered some questions about the public health infrastructure in the United States and discussed their experience with epidemic investigations in the Andean highlands, one of the students asked a penetrating question that left us all speechless for a minute:
“How is it that in a poor country like ours, we have a 96% vaccination rate, while in the US, it’s at best 80%? You have so many resources…. how can it be that you cannot vaccinate your children?”

One of my colleagues answered that in many cases, vaccines were offered but people refused to vaccinate their children because they feared vaccine side effects or believed misinformation about vaccines rather than the advice of their health care providers. The student then responded that the diseases were so much worse than the side effects, that she didn’t understand how parents could make that choice.

“That’s just it,” I said. “Most people in the United States and many other countries in the North and West have no idea how bad these vaccine preventable diseases can be. The resistance to vaccination comes from the luxury of never having seen the disease in its epidemic state.”

In my years of working overseas, I’ve never seen a parent refuse a vaccination. There are, of course, rare instances of scares and misinformation in the developing world like the Oral Polio Vaccine scare in Nigeria in 2003 when parents were led to believe by local leaders that the vaccine was a Western plot to sterilize their children to control the Muslim population. The low vaccination rate that resulted from that unfounded scare then decreased herd immunity to the point that there was an outbreak of polio the following year. But such misguided anti-vaccine campaigning is not a typical occurrence in developing countries, such as it is in the US or the United Kingdom where immunization opponents command the spotlight.

There was a time in the not so distant past when epidemics still raged in the US and other industrialized countries and parents saw vaccines as the life-saving miracle they truly are. When many early vaccines – like those for Diphtheria and Polio – were first made available, people stood in line for hours to make sure their children were protected. They had witnessed epidemics, seen the devastation these diseases could cause, and would not risk their children’s health for another day if they could help it. That generational memory has faded with herd immunity and the decreasing frequency of even small scale outbreaks. In short, our success at controlling epidemics through vaccination has created an obstacle to future vaccination in the minds of those who don’t know how lucky we are to have vaccines.

Nowadays I have often heard those who are wary of vaccines speak of measles, mumps and chicken pox as benign childhood diseases, almost rites of passage for a child to catch and suffer through. I have shuddered at hearing of “pox parties” where people deliberately expose their children to vaccine preventable diseases hoping they will get infected. If people truly saw these diseases for the dangerous contagions they are, I doubt they would risk their children’s health in such a manner. Aside from the suffering the infection entails for the child and family, these “childhood” diseases can cause serious and even life-threatening effects. Most people don’t realize that chicken pox can sometimes cause life threatening pneumonia, or that measles can in some cases lead to a devastating, usually fatal neurological disorder called subacute sclerosing panencephalitis (SSPE). These are just a few examples of the potential harm and mortality vaccine preventable diseases can cause.

The fact is that these vaccines were developed because these diseases are dangerous, devastating, and in many case, have no good definitive treatment……or they can cause catastrophic outcomes even when treated promptly and definitively, as in the case of bacterial meningitis.

The risk of getting the disease, and the risk of a bad outcome if the child gets the disease far outweigh any risk from vaccination. The science is clear on this. So why don’t parents see it that way in the case of vaccine hesitancy?

In looking for the answer to that question I ran across some fascinating work done by Dr. Chris Bauch and his team at the University of Guelph in Canada. Dr. Bauch is a mathematician, and he applied the principles of Evolutionary Game Theory to the behavior of vaccine resistance to see why parents make the decisions they do, even as they often agree with the medical community that we need to protect these vulnerable young children.

Because immunization programs are largely successful and epidemics in the West are rare, parents usually don’t personally know anyone who has lost a child to a vaccine preventable disease, so they grossly underestimate the risk of contracting the disease. The perception in the US is that the risk of contracting these diseases is low – even if that perception is absolutely wrong (as with Pertussis, for instance), and celebrity anti-vaccine campaigners are loud, so parents get scared hearing their testimonials and refuse vaccination – thinking erroneously that they are protecting their children from potential harm when they are in fact putting them at risk of serious disease.

Anti-vaccine activists hold up their anecdotes of supposed vaccine induced harm as proofs of the dangers of immunizations. Parents who have seen even minor vaccine side-effects sometimes go to the media and scare others into not vaccinating. Those who are sharing these negative experiences present them as the norm rather than the rare exception, and their anecdotes somehow take on the same weight as the science, as if they are now experts on vaccine effects. Christine Vara, the moderator of Shot of Prevention (an online forum about immunization) says that we have to help parents distinguish between “experience” and “expertise.” We should acknowledge that vaccine related side-effects are an unfortunate– though rare–possibility, but emphasize that the risk of not vaccinating is far greater – and that the true experts are unequivocal about this fact.

On a more encouraging note, Dr. Bauch also found that the vaccination behavior of the hesitant parents’ peer group influenced their decisions about whether or not to vaccinate. So if most of their friends were vaccinating their children, they were more likely to be open to vaccination as well, even when they had initially expressed reservations.

So what can you do to help?

You can talk to the hesitant parents in both your professional and personal spheres about why you vaccinate your own children, and share with them the video recently produced and distributed for free by the Texas Pediatric Society that addresses vaccine hesitancy and shares the experience of two Texas families who lost children to vaccine preventable diseases:

http://txpeds.org/vaccine-information

Research has shown that personal stories have more impact on behavior change than statistics, and that’s why the anti-vaccine campaigns have been so successful.

What else can we do to help save children’s lives through vaccination?

Remember all those little ones all around the world whose parents eagerly vaccinate them? The reality of infant and child mortality in the developing world, the daily agony of witnessing the death of a child on a regular basis, provides more than enough motivation for those parents to do all they can to prevent ANY disease that CAN be prevented. And yet, not all those children get the vaccines they need due to resource scarcity and lack of access to immunizations. Every 20 seconds, a child dies of a vaccine preventable disease – and most of these deaths are in the developing world, where the children who fall ill won’t be able to call an ambulance or access lifesaving care.

During World Immunization Week at the end of April, the Shot at Life initiative was launched in partnership with the United Nations Foundation to help mobilize a grassroots movement in the United States advocating for global vaccine delivery, so that every child anywhere in the world can have the same fighting chance. Check it out and lend your support:

So each of you reading this can make a difference every day, by encouraging hesitant parents to protect their children by immunizing them according to recommended vaccine schedules, by helping improve access to immunizations all over the world, and by speaking out in support of vaccination whenever the opportunity arises.

Nothing To Fear But Fear Itself

There are so many emotions and feelings associated with the birth of a baby.  Joy, amazement, love…and sheer terror!  For new parents, fear of the unknown world of parenting can begin even before that first ultrasound and can be overwhelming at times.  For nine-months, countless hours are spent reviewing all the highest-rated safety must-have items to make sure that sweet little one will be safe in their new surroundings.  After all that preparation you would think there would be nothing left to fear, but let’s face it, you will always find something to worry about.  Even after I decided that vaccinating my son was the best way to protect him, I still entertained the idea of a delayed vaccine schedule.  I simply assumed that spreading out his immunizations would somehow be a safer alternative than giving them on time as recommended by the Centers for Disease Control (CDC) and the American Academy of Pediatrics (AAP).  After talking to our pediatrician, she informed me that there have never been any scientific studies to support my concerns.  In fact, studies have shown that delaying vaccines can actually be harmful.  Children who have received vaccinations as recommended not only showed no ill effects compared to those who delayed or opted out of vaccinations, but also performed higher on tests including speech, language, verbal memory, and a list of others.

Dr. Ari Brown, author of the well-respected books, Expecting 411, Baby 411, and Toddler 411, puts it plain and simple:

“Parents who choose an ‘alternative’ vaccination schedule to somehow protect from autism and other neurodevelopmental disorders listen up: you are not doing your child a favor.”

She goes on to explain that by choosing to delay or stagger vaccinations on a homemade schedule, parents are leaving their children, who are most vulnerable, at risk of contracting potentially life-threatening diseases.

It is only natural that new and seasoned parents alike have concerns about the well-being of their children, but don’t let that fear negatively affect the health of your family.  By keeping your child up-to-date on his or her recommended immunizations you can cross off a list of worries concerning vaccine-preventable diseases.  I had to look past my unsubstantiated fears and rely not only on reliable medical professionals but also on scientific proof that advocates for life-saving preventative vaccinations.   Don’t let fear stand in your way.

No Time To Waste!

And the saga continues.  Last week I told you about that nasty stomach bug my kids had, well the next day my husband and I found ourselves sitting in the emergency room at Texas Children’s Hospital with our daughter.  After 4 days in the hospital we are finally resting comfortably at home.  This was my first, and hopefully last, time having a truly sick child and it was terrifying.  I wanted nothing more than for my happy healthy little girl to return to me as quickly as possible.

Even with all the worry and sleepless nights, I could not have been more pleased with the care my daughter and our family received during our hospital stay.  One particular aspect of our stay proved to be particularly relevant to this blog; the hospital’s focus on keeping their patients and families safe through vaccinations.  Within minutes of meeting any doctor or nurse helping our daughter, we were asked the question: “Is your daughter and everyone in your family up-to-date on immunizations?”  Knowing that the transmission of many vaccine-preventable diseases is often traced back to a family member, I was thrilled that this was a top priority in caring for my child.  Fortunately I could answer this question with a resounding “Yes” and the emergency room doctors were able to almost immediately eliminate any concern that my child had contracted a vaccine-preventable disease, saving valuable time, resources, and unnecessary testing during our hospital stay.  Having an up-to-date shot record allowed the doctors to move forward and begin my daughter’s treatment quickly and efficiently without concern of there being a much more serious situation to handle.  This was particularly relevant in our situation because some of my daughter’s symptoms could have easily been interpreted as those of the rotavirus.

Happy to be heading home!

There is nothing worse than the fear of the unknown.  In a medical emergency, the unknown can cost doctors critical time, not to mention ineffective trial-and-error methods of treatment in an attempt to determine the best course of action of an undetermined ailment.  By keeping up-to-date on vaccinations, and just as importantly, knowing your vaccine status, you can help doctors make important and time sensitive decisions about the health of you and your children.
