Vaccines Don’t Cause Autism

8 02 2017

Vaccines don’t cause autism.

I’ve been saying this for 20+ years. I’m not a scientist, and I don’t think any parent should embrace my statement based solely on my opinion.

My statement is based on the work of scientists who’ve studied vaccinated and non-vaccinated children in multiple countries, and they say: vaccines don’t cause autism.

It would be easier for researchers of Autism Spectrum Disorders (ASD) if vaccines caused autism, but they don’t. After all, if vaccines did cause ASD, then researchers and research funding could all focus on vaccines.

But, vaccines don’t cause autism. In a way, it’s good to know that, because funders can save their money by not investing in yet more studies that will conclude that vaccines don’t cause autism.

And researchers can spend their time zeroing in on the (probably) many causes of ASD without spending a moment more on vaccines as a research subject.

If you are a parent of a baby or child about to be immunized, be prepared for the young one to have a sore arm, fever, swelling at the site of injection, or many other minor and short-term side effects of vaccination.

These are not fun for the child, and are worrisome for mom and dad, but you don’t have to worry about ASD as a side effect of vaccination because—

Vaccines don’t cause autism.

Please make an appointment with your child’s healthcare provider to discuss any questions you have about vaccines. You are the parent, and you should never feel that you can’t ask questions.

As you browse the Internet for information, I encourage you to follow the science, not the personal stories that sound scary. There are so many websites, blogs, bulletin boards, listservs, Facebook pages, tweets, and so on that say this and that, it’s hard not to be swayed by a good tale.

But this is your child, and you don’t want to guess. You want to know. Peer-reviewed studies help us determine what’s safe and what’s not safe for our child.

After 20+ years, this I know: vaccines don’t cause autism.

Measles – What’s The Big Deal?

2 06 2016

Why are public health people excited about a handful of measles cases?

Right now there’s an outbreak in Arizona. As of the moment I’m writing these words, outbreak in this instance means 11 cases. Doesn’t sound like a big deal.

But, there are reasons for concern.

To put some perspective on this, prior to 1980, before most kids were getting immunized against measles, infection caused 2.6 million deaths each year.

Measles is wildly contagious. Let’s say I’m infected with measles—I pop into the local Walmart’s restroom, do my thing, wash my hands, and cough before I go out the door. Everyone who enters that restroom for the next two hours will be exposed to the virus, which is hanging in the air and also waiting on the countertops, taps, and doorknob.

Just walk into the restroom and you’re exposed. It’s that easy to pick up.

Protection comes through immunization, although there are some who have been immunized who will still become infected. No vaccine protects 100% of the people 100% of the time.

Keeping your hands clean and away from your eyes, nose, and mouth also helps to prevent infection.

When you have measles, you will almost surely get a rash. What most of us don’t realize is measles can bring so much more than a few red spots:

  • Pneumonia
  • Ear infections
  • Diarrhea
  • Swelling of the brain, which may lead to deafness or intellectual disability
  • SSPE – a fatal disease which lurks in the body for years after the initial measles infection disappears
  • Death

When you can become infected by simply breathing the air an infected person passed through two hours ago, it’s reason enough to get excited.

Make sure your family is protected through immunization, and check with your healthcare provider if you’re not clear about your family’s immunization history.

Preventing measles is worth a minute of our time.

Why We Think Flu Vax Gives Us Flu (But We’re Wrong)

17 12 2015

My Uncle Wayne will swear that, in 2008, he was vaccinated against flu and within a week was laid up in bed with—yes—a case of flu.

A lot of us believe that getting the flu vaccine will infect us with flu, and here’s why that idea is so common (and so wrong):

Reason 1
The flu vaccine takes about two weeks to become effective in our bodies. If we’re exposed to a flu virus anytime just before or after our vaccination, our bodies are on their own.

Getting vaccinated and then getting the flu . . . it’s really just a matter of timing. Coincidence. The two events happen around the same time – getting vaccinated against flu and getting infected with flu – but one doesn’t cause the other.

Reason 2
Around this time of year, flu is what we hear about. The public health people are out in full force to get us vaccinated against the prevailing flu viruses. It’s called cold and flu season, but flu is the star.

But, there are cold germs and other viruses floating around that cause symptoms similar to flu symptoms. Our default thinking is that we have flu, but the reality may be that we have a bad cold, which also stinks, but is not influenza. So, it’s a misdiagnosis.

Reason 3
There are many flu viruses floating around the world. Each year, the World Health Organization and others try to determine which viruses will be dominant during that particular flu season. Sometimes they’re wrong, and the available flu vaccines, which were made to fight those specific flu viruses, don’t do a good job of protecting us from what’s really out there.

Reason 4
No vaccine protects 100 percent of the people 100 percent of the time. It’s possible to get vaccinated against the flu strains currently in your area and still end up with flu because, for whatever reason, the vaccine simply did not protect you.

Reason 5
You cannot get flu from the flu vaccine because it’s made to prevent that very thing from happening.

The flu vaccines that are delivered through a needle are made from totally dead flu viruses, or tiny specks of deconstructed flu viruses.

There is not a spark of infectivity left in them.

The flu vaccine that is sprayed up the nose has live flu virus in it. But, and it’s a big-sized but, the virus in this vaccine is weakened to such an extent that it can’t make you be sick.

So there we are.

The flu vaccines protect many people. Getting vaccinated is a good idea, and one you should discuss with your provider.

To help prevent infection, get vaccinated as we discussed, and keep your hands clean all day. Try not to touch your mouth, nose, or eyes with hands that might not be clean. Those areas are prime spots for disease transmission.

See you on the other side of cold and flu season!

Hepatitis A, B, C, D, and E

28 07 2015

It’s World Hepatitis Day.

We want to use this day to remind moms and dads that hepatitis is around and some of it can be prevented by vaccination.

Hepatitis C is a bloodborne virus that attacks the liver. It is not vaccine-preventable. If babies are infected it’s usually from their hepatitis C+ mothers or, and this is unlikely these days, from a blood transfusion. It’s unlikely because the screening process of donated blood is pretty darn thorough. But, germs have slipped through that screening process.

Teens and young adults may become infected, primarily through sharing of needles, sex with an HCV+ person, or sharing personal items such as razors or toothbrushes that may be contaminated with HCV.

There are effective treatments that work on a good portion of hepatitis C-infected children. But not on all infected children. Work is ongoing in this area.

Hepatitis C is frequently a chronic infection, meaning that if treatment is not effective, you will be infected for your lifetime.

Hepatitis A is vaccine-preventable. Normally, it’s passed person-to-person through the fecal-oral route, which is when something you eat or drink has been contaminated with hepatitis A+ poop. If you haven’t been vaccinated, chances are you will become infected.

This virus makes you feel lousy and can, rarely, do serious damage to the body. It does not become a chronic infection. It infects you and then goes away, like a cold virus.

Hepatitis B is vaccine-preventable. It’s transmitted in a lot of ways—mom to newborn, sharing needles or personal items, sex with an infected person, even household (nonsexual) contact. If a mom is aware of her infection prior to giving birth, shots can be given to the baby within 12 hours of birth that are effective at stopping tranmission of the virus from mom to baby. However, when babies are infected, almost half of them in the US will become chronically infected. In developing countries, that figure shoots up to 90 percent.

Today, despite the vaccine, approximately 1,000 babies become chronically infected with hepatitis B each year in the US. Many of the moms-to-be who are infected are unaware of their infection. Every pregnant woman should be tested for hepatitis B so that action can be taken at birth to prevent infection of the newborn.

Hepatitis D is an odd virus. You have to be infected with hepatitis B before you can get hepatitis D. It’s vaccine-preventable in that, if you get immunized against hepatitis B, you won’t be able to get hepatitis D.

Hepatitis E is similar to hepatitis A in the way it is transmitted—the fecal-oral route. It’s rarely a chronic infection. For most people, they get it, get sick, and get over it. It can however be dangerous for pregnant women, with a 10% – 30% fatality rate for this group. It’s not often found in the US but can be easily picked up in some other parts of the world.

That’s about it for hepatitis in the US. To prevent a hepatitis infection (and lots of other infections), wash your hands throughout the day, put barriers between yourself and another person’s blood or body fluid, and use the available vaccines. The trick is to do these things with everyone. It’s impossible to tell who is infected with what, most of the time, so the safest course of action is to assume everyone is infected with something and then act accordingly.

Got any tips? Hope you share them will us in the comments.

NOVA: Vaccines – Calling The Shots

28 08 2014

Premieres Wednesday, September 10, 2014 at 9PM/8c on PBS!

 

Press release from NOVA about this fascinating documentary:

Measles. Mumps. Whooping cough. Diseases that were largely eradicated in the United States a generation ago are returning.

Across America and around the globe, children are getting sick and dying from preventable diseases—in part, because some parents are choosing to skip their children’s shots. How and why do vaccines work? What are the biggest concerns and misconceptions, and what are the risks to the child and society when people decide to forego immunization? The award-winning science series NOVA helps viewers find the answers they need.

Misinformation about vaccines can spread quickly, creating confusion about the relative risks of vaccinating vs. not vaccinating. VACCINES–CALLING THE SHOTS is an important new film that encourages parents to ask questions and use the best available evidence to make decisions about how to protect their children.

This documentary travels the globe to provide the latest evidence and answers.  Featuring scientists, pediatricians, psychologists, anthropologists, and parents wrestling with vaccine-related questions, the hour-long film explores the history and science behind vaccinations, tracks outbreaks, and sheds light on the risks of opting out.  The film, produced for NOVA by Tangled Bank Studios in association with Genepool Productions, premieres Wednesday, September 10 at 9PM/8c on PBS (check local listings).

“Immunization plays a crucial role in our public health, yet there is a tremendous amount of apprehension and confusion around the topic,” said Paula S. Apsell, Senior Executive Producer for NOVA. “In VACCINES—CALLING THE SHOTS, NOVA dispels the myths and examines the latest science, engaging parents and viewers in a conversation with real answers about the best way to protect their families.”

“With the return of measles, whooping cough and other highly infectious diseases, we saw an opportunity to team up with NOVA to provide clarity for viewers about vaccination and what’s really at stake here for all of us,” said Michael Rosenfeld, Executive Producer for Tangled Bank Studios.

The vast majority of Americans—more than 90 percent—vaccinate their children, and most do it on the recommended schedule. Yet many people have questions about the safety of vaccines, and at least 10 percent of parents choose to delay or skip their children’s shots. The film illustrates how vaccines not only protect individuals, but also safeguard entire communities. The higher the overall vaccination rate is, the more protection for everyone.  For highly infectious diseases like measles, 95% of the community must be vaccinated to shield the larger population, a concept known as “herd immunity.” If the rate drops below that 95% threshold, even by just a few percentage points, this layer of protection can collapse, sometimes leading to the kinds of outbreaks reported in recent news headlines. Measles was declared eliminated in the U.S. in 2000; however, the Centers for Disease Control and Prevention report 566 confirmed cases in 2014, as of July 11. In 2012, there were nearly 50,000 cases of pertussis, also known as whooping cough, and 20 deaths, in the U.S.

Highlighting real cases and placing them in historical context, VACCINES—CALLING THE SHOTS demonstrates just how fast diseases can spread—and how many people can fall sick—when a community’s immunity barrier breaks down. The film chronicles a 2013 measles outbreak in Brooklyn, New York, in which 58 people fell ill, including two pregnant women. Dr. Paul Offit, a pediatrician and infectious disease expert at The Children’s Hospital of Philadelphia, offers the physician’s perspective on the vulnerable immune systems of young children, the history of vaccines, and how diseases re-emerge when immunization rates decrease.

Some parents—including a number of new mothers interviewed in San Francisco—are concerned about the risk of adverse reactions from vaccination. The film acknowledges that there are very rare risks, but Dr. Brian Zikmund-Fisher, a psychologist and risk specialist at the University of Michigan School of Public Health, puts those risks in perspective: You’d need about ten football stadiums, each with 100,000 people, to find a single serious allergic reaction to a vaccine.

NOVA viewers meet Alison Singer, President of the Autism Science Foundation, and her daughter Jodie, who has autism. Singer cites the overwhelming scientific evidence refuting a link between vaccines and autism and discusses the lingering effects of a long-discredited study on public perception. The film further explores autism with new science from Dr. Dan Geschwind that reveals its genetic causes. His team and others have pinpointed mutations that affect the wiring of the developing brain—compelling evidence that autism begins in the womb.

VACCINES—CALLING THE SHOTS also follows Dr. Amy Middleman, Adolescent Medicine Specialist at the University of Oklahoma’s Health Sciences Center as she consults with patients and their parents on the safety and effectiveness of the controversial HPV vaccine, which protects against the cancer-causing human papillomavirus.

We’ll be watching on 10 September!





A Thoughtful Choice

17 04 2014

I remember lining up at school in the ‘60s to get vaccinated against smallpox and a few other diseases for which there were vaccines.

I also remember the years when my brothers and I took turns at getting measles, mumps and other diseases for which there were no vaccines.

In the end, we three were fortunate—no permanent harm from our maladies.

Fast-forward 30 years. My daughter was four months old when she was diagnosed with hepatitis B. She had not been vaccinated and subsequently developed a chronic infection.

It all sounds mundane when read as words on a screen. But in those early years, the heartache and anger I felt at having my daughter’s life so affected by something that was preventable . . . well, it was almost more than I could bear.

But again, we were fortunate. After years of infection, her body turned around and got control of the disease. Although we have bloodwork done every year to keep an eye on things, she has a good chance of living the rest of her life free of complications from this infection.

Over the years, I’ve met other parents whose children were affected by vaccine-preventable diseases. Some, like Kelly and Shannon, chose not to vaccinate their kids and ended up with horrible consequences. Kelly’s son Matthew was hospitalized for Hib and they came within a breath of losing him. Shannon did lose her daughter Abigale to pneumococcal disease, and almost lost her son. He recovered and was released from the hospital, at which time they had a funeral for their daughter.

Because of my job, I talk to and hear from many families with similar stories. Some children have died, some remain permanently affected, and some have managed to recover.

Also because of my job, I hear from parents who believe vaccines are not safe, and that natural infections are the safer choice. I understand and have experienced the emotions we as parents feel when something happens to our children. In a way, I was lucky. I knew exactly what caused my daughter’s problems. A simple test provided a definite diagnosis.

If we can’t identify the cause of our children’s pain or suffering, we feel like we can’t fix it and we can’t rest until we know the truth. When the cause can’t be found, we latch onto if onlys. What could we have done differently to keep our kids safe? If only we hadn’t taken her to grandpa’s when she didn’t feel good. If only we hadn’t vaccinated him on that particular day. If only. The problem is, the if onlys are guesses and no more reliable routes to the facts than playing Eenie Meenie Miney Mo.

The deeper I go into the world of infections and disease prevention, the more obvious it is to me that the only way to find the facts is to follow the science. Now granted, one study will pop up that refutes another, but I’ve learned that when multiple, replicable studies all reach the same conclusion, then I can safely say I’ve found the facts.

In our family, we vaccinate because for us, it is the thoughtful choice.

Flu Then and Now

12 12 2013

The CDC came out with a lot of flu info today. Here’s a rundown on the highlights with a link to the rest at the end of the post:

CDC says that during last year’s flu season, 45 percent of the U.S. population aged 6 months and older was vaccinated against flu.

Influenza vaccination during 2012-2013 prevented 6.6 million illnesses, 3.2 million medical visits and 79,000 hospitalizations. Overall, this resulted in 17 percent fewer illnesses, medical visits, and hospitalizations than would have happened without flu vaccination.

The numbers are big, but the percentage is small. We need to increase the numbers of those vaccinated, and we need to come up with a more effective vaccine.

CDC estimates that during 2012-2013, there were 31.8 million flu-associated illnesses, 14.4 million medically attended illnesses, and 381,000 hospitalizations in the United States.

As for this year, CDC is recommending that those who have not yet been vaccinated do so. It takes about two weeks after vaccination for the body to develop immunity.

Most years, the flu season in the US peaks between January and March, which is reason enough to get immunized in December.

This year looks to be typical. Get vaccinated now and save yourself and your family the misery of infection.

The recommendation is that everyone six months of age and older get immunized against flu.
