We have a moral responsibility for the health of our children and this has to dominate any other belief systems we hold. Even worse, by not vaccinating children, we are putting other people’s children at risk, as well as our own. If another child dies of measles, or whooping cough, or meningitis, and was infected by our own, non-vaccinated child, are we partly responsible?
And they should start by ignoring Wakefield’s lies. Because vaccines would have saved this baby’s life.
Over 5.2 billion people died in the 20th Century. Although the 20th Century ended a mere 13 years ago, from a statistics standpoint, we know we will probably die of different diseases (and other less natural causes) than our forebears. The causes of death evolve over time as medicine improves, science ameliorates risk, lifestyles change, environments shift, and politics reshape our world. British data journalist David McCandless (of Information is Beautiful) created this fascinating infographic based on a project, commissioned by the Wellcome Trust, a U.K. charity devoted to human health, called Death in the 20th Century, which shows us, graphically, the leading causes of mortality from 1900 to 2000, worldwide.
Some of the numbers are shocking. Humanity is the cause of nearly 1 billion (or just short of 20%) of the deaths in the 20th Century. These numbers include war, murders, religious intolerance, suicide, and other deadly crimes that humans perpetrate against one another. Maybe the 21st Century will knock that number down, though I doubt any of us are optimistic given the way this century has started.
But the most interest information is in the Infectious Disease section. Nearly 1.7 billion people have died from infectious diseases. Some of the more interesting numbers are:
In the 21st Century, the numbers of deaths from these diseases will probably be in the few thousand worldwide. Why? Because of vaccines. Not better sanitation. Not better health care facilities. But because of vaccines.
And in the 21st Century, as more vaccines are developed and brought to market, many of these infectious diseases will be less of a problem.
Vaccines saves lives. Literally hundreds of millions of lives.
A recently published study in Pediatrics evaluates reports of increased rates of pertussis in the six years after receipt of the fifth (of five) DTaP doses. These reports suggest that waning of immunity to pertussis from DTaP is occurring before the recommended booster age of 11 to 12 years. The researchers tracked more than 400,000 Minnesota and Oregon children using immunization records and state health department whooping cough data. All of those children were born between 1998 and 2003 and received the recommended series of five DTaP shots, the final one usually given at 4-6 years old.

A new article published this week in the Journal of the American Medical Association (JAMA) by Misegades et al. analyzed a recent whooping cough (Bordetella pertussis) outbreak in California children. Misegades determined that those who had not been vaccinated against the disease were nine times more likely to get pertussis than those who had received the entire five-shot series. However, among children who were fully vaccinated, the longer it had been since their final dose of the DTaP vaccine (which protects against diphtheria, tetanus and pertussis), the higher the risk of contracting whooping cough. This is in line with the decrease in effectiveness of the vaccine that has been discussed here and elsewhere. Continue reading “Whooping cough vaccine–facts about waning immunity”
The Montana Department of Health has reported (pdf) that as of November 15, 2012, a whooping cough (Bordetella pertussis) outbreak has reached over 500 cases since the beginning of the year, compared to only 129 cases during the same time period in 2011. As of November 15, 33 cases of pertussis were found in infants of less than one year of age. Of these, four have been hospitalized. Because Montana is has a small population (about 1 million people), the overall incidence rate year to date is 50.5 pertussis cases per 100,000 Montana residents.
This past spring, there was a pertussis outbreak in several Montana counties, but it seemed to abate during the summer. The Department of Health is reporting that Flathead county, a northern county that borders Canada, is currently struggling to contain an outbreak in five school districts. “Since the beginning of October, we have 35 cases,” said Community Health Services Director for Flathead County Jody White. “Usually we won’t even see 35 in a year, so it is definitely unusual to have this many.”
On October 24, 2012, the Centers for Disease Control and Prevention recommended that “providers of prenatal care implement a Tdap immunization (Tdap or DTaP vaccine) program for all pregnant women. Health-care personnel should administer a dose of Tdap during each pregnancy irrespective of the patient’s prior history of receiving Tdap. If not administered during pregnancy, Tdap should be administered immediately postpartum.” This recommendation is based upon the Advisory Committee on Immunization Practices (ACIP), a group of medical and public health experts that develops recommendations on how to use vaccines to control diseases in the United States, guidelines, published Fall 2011, for whooping cough(Bordetella pertussis).
ACIP reviewed published and unpublished data from VAERS, Sanofi Pasteur (Adacel) and GlaxoSmithKline (Boostrix) pregnancy registries, and two small studies here and here. ACIP concluded “that available data from these studies did not suggest any elevated frequency or unusual patterns of adverse events in pregnant women who received Tdap and that the few serious adverse events reported were unlikely to have been caused by the vaccine.” In addition, both tetanus and diphtheria toxoids (together) and tetanus toxoid (alone) vaccines have been used worldwide in pregnant women to prevent neonatal tetanus without negative effects. The ACIP concluded that administration of the pertussis vaccine after 20 weeks of pregnancy was preferred to minimize any risk of a low percentage adverse event.
According to the CDC, only about 3% of pregnant women receive the vaccination. However, the CDC believes if the new recommendations are implemented, there would be a 33 percent reduction in cases, a 38 percent reduction in hospitalizations and a 49 percent reduction in deaths from whooping cough.
Outstanding news. Tara Haellereported inNature News & Comment that US state legislatures are beginning to pass laws that make it more difficult for parents to obtain so-called personal exemptions to vaccinations before children attend public schools.
