They Say: Another Reason to Vaccinate Your Kid
The no-vax movement got more bad news this week with a report in Pediatrics that confirms herd immunity does not keep the non-vaccinated safe.
The study by researchers at Kaiser Permanente Colorado and Johns Hopkins Bloomberg School of Public Health determines kids whose parents opt out on vaccines are twenty three times more likely to develop pertussis than their vaccinated peers.
More commonly known as whooping cough, the incidence of pertussis was rapidly declining in the U.S. from the 1940s through the late nineties thanks to vaccinations. But with parents forgoing the vaccines, the numbers are back up – big time. In 2005 alone, more than twenty-five thousand cases were reported (for comparison check out the numbers in 1976 – only one thousand ten cases in the entire U.S.).
Those numbers should have proven the importance (and efficacy) of the vaccine, but parents have been skipping the vaccine in increasing numbers, or delaying it as part of the system touted by Dr. Robert Sears, a much revered pediatrician by the middle-of-the pack vax crowd. The study at Kaiser found that eleven percent of the kids who contracted pertussis were kids whose parents actually refused the vaccine (which makes a difference – these weren’t kids whose parents opted out because of a medical issue that kept them from getting the vaccine).
What a fair number of anti-vaccine parents fail to realize is the problem isn’t just the other kids their kids are coming in contact with. Even if the majority of American kids get the vaccine, adults age out of their immunity. Which means unless they head to the doctor for a booster, they’re susceptible to the disease, and carriers who could be passing it on to your kids (studies indicate at least one third of pertussis cases were transmitted by mother to child).
And pertussis is not a silly, laugh it off disease. It can kill, particularly infants.
So if herd immunity isn’t protecting your kids from pertussis, what else isn’t it protecting them from?

Anonymous commented on Jan 01 70 at 12:00 amI’m 35 and have pertussis. My mom freaked out when I told her. She insisted that I’d been vaccinated when I was little. None of my friends, coworkers, or family new that the vaccine “wears off.”
I honestly wouldn’t wish this on my worst enemy. Please please please get boosters. It sure beats the sore throat, headaches, strained tongue (yeah…it really hurts), bruised ribs, and time missed at work.
Anonymous commented on Jan 01 70 at 12:00 amOf the 25,000 cases reported in 2005, how many were hospitalized and how many were fatal? It is a terrible disease, no doubt, but how deadly is it?

What I don’t understand is that everyone would be so pissed at the parent of the unvaccinated child but what if they “got it” from a child that was vaccinated? As SWalker said, her doctor sees the disease in both vaccinated and unvaccinated children. It just really, really confuses me. All, well okay…most, parents are doing the best they can for their children.
Would you also be mad at a parent if a vaccinated child got severely ill from the vaccine? No, you would feel sad for them. But, if an unvaccinated child got ill you would be all high and mighty and say they got what they deserved? Parents just want answers, tests, thorough studies done. They aren’t being done and that is sad.
Thank you for the links CV but the first one was just a synopsis of other studies, not a study itself. And the second one from the cdc pretty much proves that vaccinated individuals can get the disease and be silent carriers infecting others…the third I don’t have a membership to medscape so I couldn’t access. It would be interesting to actually see the original study still…
Anonymous commented on Jan 01 70 at 12:00 amI have another point of view: just this past fall, I caught whooping cough because I work with medically fragile children who are unable to receive a pertussis vaccine. It SUCKS. The majority of staff members did not know that adults need a booster shot, and 3 other teachers and I were forced to miss 5 days of work (that’s how long you’re contagious), and my husband had to wear a surgical mask just to sleep next to me. The health department ordered me to stay home or be arrested, and my parents, siblings and friends who’d spent a lot of time with me ALL had to go on a Z-Pak. I thought I was going to crack a rib or suffocate every time I coughed. I could sleep for about an hour at a time before waking up with a massive coughing fit.
I totally understand why those students at my school didn’t get vaccinated against it. Most of them are on seizure meds that have potentially life-threatening interactions with a Tdap. But if I taught at a regular school, and caught it from a kindergartner whose parents made a choice to skip vaccines, do you know how PISSED I’d have been? If I had gotten pregnant a month earlier, how terrified I’d be? How worried the other women at work with newborns were scared they could still bring it home and infect their babies? I wish more people would consider the fact that vaccines don’t only protect their own children, they protect other children and adults as well.
Anonymous commented on Jan 01 70 at 12:00 amWell, this kind of hits home since my husband and daughter are both currently recovering from pertussis. At the encouragement of my pediatrician, we had opted out of vaccines for her until she turned 2. So we started vaccinating her about 2 months before she came down with pertussis.
Although my husband and daughter have now naturally boosted their immunity (and me too, I hope!) we may change vaccine strategies for baby #2! From the timing, it seems my husband may have passed it to my daughter, not the other way around.My pediatrician says that he sees about 70 cases of pertussis yearly, about 50% vaxed and 50% non vaxed kids. And my daughter did have one vax on board when she contracted the cough. I’m not sure what all this means, but maybe she would have had a worse case if we had not started the vax. I will say that I really trust my pediatrician, and he was able to diagnose the pertussis within 2 minutes of seeing my daughter, when another Dr. just said she had bronchitis and put her on antibiotics
I just thank God she wasn’t younger when she got it.
Anonymous commented on Jan 01 70 at 12:00 amSo what if the actual kill rate from pertussis is low? Who really wants to risk their child picking up a highly-contagious illness that can result in ear infections, pneumonia, seizures/convulsions, brain damage (from oxygen deprivation), retinal damage and hernias (from the severe coughing spells)? And even if your own child’s illness is mild, why would you want to risk them passing it on to someone else who may develop a severe case?
Thanks Dr.M and CV for your contributions.

Anonymous commented on Jan 01 70 at 12:00 amAre vaccines necessary? Are they safe? Sources from the internet, TV, radio and the newspaper abound with information about vaccines. It is more interesting to present a story that questions the validity of giving vaccines than to support something which, if successful, nothing happens. The media has given a voice to a vocal group that has raised concerns about vaccines for almost as long as the success of vaccines have been evident. These are folks who are against all vaccines, no matter what the evidence shows. They feel that vaccines are a poison and that the
dhsredhead commented on Jan 01 70 at 12:00 amThis doesn’t prove anything. Only 11% of the children who contracted the disease had parents who opted them out of being vaccinated. How many of the children who contracted the disease were vaccinated? Also if the cases were mostly passed from mother to child, the easiest remedy for this would be for parents of unvaccinated children to continue nursing their infants until the dangers of diseases like this have passed.
Anonymous commented on Jan 01 70 at 12:00 amAre cases declining? According to the cdc there were 10,454 cases reported in 2007 and 10 deaths. That is a .095% chance of dying if getting a diagnosable case, in 2007. Or in more happy terms…a 99.905 chance you would be just fine AND end up with lifelong immunity. And it is well known that there are even more cases that are mild and left undetected or diagnosed so that % is actually even higher. The author said there was over 25,000 cases in 2005. She didn’t tell you that 2005 was the height of the most recent epidemic that occurs every 3-5 years and that most of the increase was in adolescents and adults who’s immunity had waned due to the wearing off of the vaccine(according to the cdc). Pertussis is no fun, I agree. But scare tactics just aren’t science.
Anonymous commented on Jan 01 70 at 12:00 am“Even if vaccinated children are still at risk for pertussis, they would be at reduced risk for both infection and severe cases of the disease.”
Does anyone have a resource or study that shows unvaccinated children get a more severe case of a disease than a vaccinated child who gets sick also? I am unaware of any true evidence of this but would love to read a case…of course it is probably impossible to actually predict this because we would never know how any one child would react to a disease, unvaccinated or not. I would really like to know if there is any basis for this argument or if it is just a theory.
And I don’t think Jeanne was blaming unvaccinated children for resurgence but most people do, claiming that they are underminding herd immunity by not being vaccinated…(even though they may be immune but haven’t been tested for that.)
Anonymous commented on Jan 01 70 at 12:00 amSo 11% had parents that opted out of the vaccine. Does that include for religious purposes? (Hey, its a legit question, I am assuming this is the case)
The remaining 89%…what percent weren’t old enough to have had the full course of the vaccine (i.e. under around age 2)? Feeling too lazy to do much research myself right now, but it seems like that has been a quoted statistic in other similar stories about resurgent “formerly gone vaccinated against diseases” such as the measles. Also wondering whether some kids fell into “gaps” where they either didn’t complete the series or some dosing information changed mid-series. (A whole batch of children my age – as in four years worth at one practice in town, had to be revacc’d for MMR for a reason similar to this….something changed, doses weren’t given at the correct age, whatever it was. That’s a lot of children. It was discovered when we had a small outbreak of measles…)
Anonymous commented on Jan 01 70 at 12:00 amContracting pertussis may build natural life-long immunity, but no one wants to see a baby struggling with pertussis, turning blue from lack of oxygen and coughing that horrible cough for weeks on end. No one wants to be an adult with a full-on pertussis infection either, believe me. I’m still in a fragile respiratory state from a full-on case of pertussis I suffered two years ago (because I was a moron and didn’t get my booster when I first heard about the resurgence). Maybe my immune system got a boost from that two months of cough-related incontinence, vomiting, inability to sleep, and cracked ribs, but the chronic respiratory infections I’ve dealt with since have not left me feeling all mighty n’ sh*t.
Fortunately I didn’t hack all over anyone’s babies while I was contagious. That would really have put a cork in the whole experience, stimulating the immune systems of infants throughout the metro area with my lovely & natural pertussis.
The booster is very easy to get. Ask your doc for one today.
Anonymous commented on Jan 01 70 at 12:00 amYes, pertussis can kill infants. But with the current recommendations for a vaccination schedule, babies are not fully vaccinated against pertussis until they’re over two – and well past the most worrisome age to get pertussis. It’s frustrating to not have a vaccine to protect your child when they are most vulnerable, but that’s the reality of the situation. And while I’m not a non-vaxer, this article misses one point I think is interesting. Any disease can be life-threatening depending on the course and the person’s immune system. But allowing one’s body to get some diseases actually helps build the immune system – vaccinating does not allow for that, even the live vaccines. And as this article states, adults age out of their vax immunity. Contracting pertussis builds natural, life-long immunity against it in the future. So I can at least understand where non-vaxers are coming from on this issue.
Anonymous commented on Jan 01 70 at 12:00 amI’m not sure Jeanne is attempting to blame the resurgence of pertussis on non-vaccinated children. I think she’s pointing out that when a contagious disease like pertussis gets a good foothold in a community, non-vaccinated children are at a great disadvantage. Even if vaccinated children are still at risk for pertussis, they would be at reduced risk for both infection and severe cases of the disease. Children who aren’t vaccinated at all for pertussis are in a bad way, regardless of who’s responsible for the reduction in herd immunity.
Anonymous commented on Jan 01 70 at 12:00 amI find it interesting that it doesn’t tell you how many kids who were already vaccinated got the disease. 11% opted out by parental decision. In my experience very, very, very few every get medical exemption so I would have to say the majority of the children who got pertussis were vaccinated anyway? Would just be interesting to know. And at least now we can’t just blame the unvaccinated for skrewing up herd immunity…looks like most adults (vaccinated as children) are doing it too.
