Truth: Whooping Cough in the U.S.
The approach to Whooping cough is eerily parallel to the approach the medical and healthcare industrial complex took to COVID - you have been warned, you can take action in your State...
Prologue: Why We Are Publishing This Report
We were in the same boat as everyone else when COVID-19 struck (C19) - but not for very long. The discernment in separating commnds and demands quickly isolated where the fear-mongering was coming from so we sought resources who had the same discernment.
What we also saw were patterns being repeated through the histories of everything related to healthcare and the medical profession - patterns that were repeated since the 1800s and always leading to the same result: the cure was more lethal than the cause.
We are seeing the same thing with the so-called Bird flu and now the Whooping cough.
The mechanism for getting knowledge out to people is the media - social media, local news, national news - and the voices you listen to determine what you believe, even if that belief is a fabricated lie meant to make you believe them.
If they want to ignore the opportunity to examine their beliefs, that is an age-old problem that even an intellect will make their entire life.
We highly suggest you bookmark this post, and after its publication, we will be making it available in PDF, adding a link at the end of the post.
Any updates to this post will be published in a new post with a link back to this one for the sake of reference, as well as those who missed this post on the first go around.
At the end of this post is a CALL TO ACTION - the ONLY way to get ahead of an anticipated problem is to get ahead of those who can influence what could go down by educating them on the truth.
VIDEO: The Truth About Whooping Cough in the U.S.
Barbara Loe Fisher, NVIC Co-founder & President, talks about the risks and failures of pertussis (whooping cough) vaccine in whole cell DPT and acellular DTaP/Tdap shots and how misinformation is wrongly placing blame on parents of unvaccinated children for pertussis outbreaks when pertussis is occurring in undiagnosed vaccinated persons.

Once again, this year Americans are being warned that B. pertussis whooping cough cases are on the rise and society is being endangered by parents who don’t vaccinate their children. 1 2 3 4 5
That myth goes back to the early 1980’s, when parents of DPT vaccine injured children in the U.S. were calling for a less reactive pertussis vaccine because our children were dying and being brain injured by the crude whole cell pertussis vaccine, 6 7 an especially toxic vaccine that is still being given today in some other countries. 8
In the late 20th century we were accused of causing whooping cough outbreaks just by talking about crippling DPT vaccine reactions, 9 very similar to the accusations leveled against people who talked about crippling COVID shot reactions that led to widespread censorship of freedom of speech in the 21st century. 10 11 12 13
Back in the 1980s, while we were researching the medical literature and learning about how the DPT vaccine could kill and disable children, we were also discovering that the whole cell pertussis vaccine was not reliably preventing infection with or transmission of B pertussis that causes whooping cough. 14
In the early 1980s, scientists were reporting that whole-cell pertussis vaccine acquired immunity lasted only about 2 to 5 years, and whooping cough was circulating in countries with 90 to 95% vaccination rates, including in people showing few or no symptoms. 15 16 17 18 19 20 21 22
Cases of asymptomatic transmission of whooping cough were not being counted in official pertussis statistics in the 1980s when nearly every child in the U.S. was getting 4 or 5 doses of whole-cell pertussis vaccine. 23
And today, cases of asymptomatic whooping cough in children and adults, who have gotten 5 to 7 doses of acellular pertussis vaccine, are not being counted either. 24
Public health officials and doctors continue to insist publicly that vaccines do prevent infection and transmission of disease. 25 26
In fact, the utilitarian rationale for mandatory vaccination laws is based on the premise that everyone must be forced to get vaccinated, that it is our moral obligation to be willing to sacrifice our lives or the lives of our children by risking a disabling or life-ending vaccine reaction for the greater good of society. 27 28 29
The argument is that forcing everyone to get vaccinated creates “herd” or “community” immunity,30 31 and society is protected from infection and transmission of diseases, which public health officials always claim have more serious and frequent complications than vaccines. 32
So the scientific and moral rationale for mandatory vaccination rises or falls on whether or not vaccines reliably prevent infection with and transmission of diseases caused by microbes.
During the coronavirus pandemic declaration in 2020, public health officials and lawmakers mandating the COVID shot insisted that none of us would get sick or make other people sick if we rolled up our sleeves and got COVID shots. 33 34 35
But soon it became painfully clear that the mRNA biological product labeled a COVID vaccine did not prevent the disease, 36 no matter how many COVID shots a person got, 37 and the risks for heart and brain inflammation were significant.38 39 40 41
Infectious microbes adapt to survive and circulate in human and animal hosts.42 43
The truth is that you can get vaccinated according to the CDC’s recommended schedule and still get pertussis,44 measles,45 46 mumps,47 influenza48and other vaccine-targeted diseases, but only show few symptoms or no symptoms at all.
Vaccinated and unvaccinated people can also transmit infection to other vaccinated and unvaccinated people, even as there is mounting evidence that a natural infection often provides a more robust and longer-lasting immunity than a vaccine.49 50 51
Pertussis is an excellent example.
Since 1986, I have been talking about the fact that the pertussis vaccine does not reliably prevent infection and transmission of whooping cough.
In 1986, when our organization - then known as Dissatisfied Parents Together (DPT) – held the first public demonstration in front of the Centers for Disease Control (CDC) in Atlanta to protest the reactivity of whole cell pertussis vaccine, I gave an oral presentation to the Advisory Committee on Immunization Practices (ACIP) summarizing an investigation I had conducted into DPT vaccine failures in 8 states reporting whooping cough outbreaks.
I presented data obtained from the 8 state health departments, which revealed that in 6 out of 8 states, more than half of the reported cases of whooping cough in children and adults had been vaccinated.
In 1 state, more than 70% of the whooping cough cases with a known vaccination history had received three or more DPT shots. 52
Time to Dispel Myths and Lies About Pertussis and Pertussis Vaccines
What’s old is new, and it is time to dispel the myths and lies being told about the old whole-cell and newer acellular pertussis vaccines.
FACT: Both the highly reactive whole cell DPT vaccine licensed 1948, 53 and the less reactive acellular DTaP vaccine licensed in 1996 for infants 54 can fail to prevent infection and transmission. 55 Those 2 vaccines typically provide 2 to 5 years of temporary vaccine acquired immunity – at best lasting about 12 years; 56 57 58
FACT: Natural infection with B. pertussis often produces a more robust and longer lasting immunity of between four and 20 years – at best 30 to 70 years; 59
FACT: An unknown number of vaccinated children and adults – perhaps millions - are silently infected with pertussis in the U.S. every year and show few or no symptoms and doctors do not identify those cases, which means those cases are not reported to the government; 60 61
FACT: In response to mass pertussis vaccination campaigns beginning in the 1950s, the B. pertussis microbe evolved first to evade whole cell pertussis vaccines in the 1980s and, in the 1990s, that evolution accelerated to evade acellular pertussis vaccines. 62
Now, here is the rest of the story in more detail…
High Child Pertussis Vaccination Rates in U.S. for 35 Years
Child pertussis vaccination rates in the U.S. for children attending school have remained high and relatively stable for the past 45 years.
Consistently, more than 90 to 94% of kindergarten children have received 4 to5 pertussis-containing shots either in whole-cell DPT or acellular DTAP. 63
In the 2023-2024 school year, nationally 92% of children attending kindergarten had gotten 5 doses of pertussis containing DTaP, with 1 state reporting a more than 98% vaccination rate. 64
Among 24-month-old children, there was a 94% pertussis vaccination rate with 3 doses of DTaP and 81% with 4 doses in the years 2019 and 2020. 65
Today, 89% of teenagers attending high school have gotten at least 1 Tdap booster shot. 66
That’s a lot of pertussis vaccination going on in America for a long time among children of all ages, many of whom are now adults in their 20s, 30s, and 40s.
So, why beginning a decade ago, did public health officials report that large numbers of fully vaccinated pre-schoolers in Florida, 67 and fully vaccinated teenagers in California, 68 and fully vaccinated sisters and brothers of newborn infants were spreading pertussis whooping cough - 69 even though most had gotten every pertussis shot recommended by the CDC?
To answer that question, let’s do a quick review of the history of pertussis and pertussis vaccine.
DPT Licensed in 1948 & DTaP in 1996 for U.S. Babies
Pertussis whooping cough has been around since at least the 15th century, 70 and it can be deadly for babies who cannot breathe when the sticky mucous produced by the gram negative bacteria clogs their tiny airways.
Signs of whooping cough begin with typical cold symptoms of fatigue, runny nose, sometimes a low-grade fever, and a slight cough for several weeks.
It progresses to violent spasmodic coughing that ends with a “whoop” in infants or small children as they try to breathe and then vomit up thick mucus through the nose and mouth, especially at night.
Historically referred to as “the 100-day cough,” a pertussis infection can last for four to 12 weeks, and serious complications include bronchitis, pneumonia, brain inflammation, and death.
Doctors prescribe antibiotics, and there are holistic therapies, but the course of the disease is rarely altered, and rehydration, rest, and good nutrition are always recommended. 71
The first crude whole cell pertussis vaccine, which contained bioactive pertussis toxin and endotoxin, was licensed in 1914, but was not given widely to children until after 1948, when it was combined with diphtheria and tetanus vaccines into the DPT shot that also contained aluminum and mercury. 72
DPT was used in the U.S. until 1996, when a purified, less reactive acellular pertussis vaccine (DTaP) was licensed for use by infants. 73
Acellular pertussis vaccines contain far less bioactive pertussis toxin and endotoxin and do not contain mercury. 74 75 76
While DTaP has been proven to be far less reactive than whole cell pertussis vaccine in DPT, 77 78 79 80 81 acellular pertussis vaccine can still cause brain inflammation and permanent brain dysfunction in vulnerable individuals. 82 83 84 85 86
In 2019, World Health Organization (WHO) officials reported that 86% of the world’s infants had received at least 3 pertussis-containing shots. 87
75% Drop in Pertussis Deaths Before DPT Licensed in 1948
But what about deaths in the U.S. from B. pertussis whooping cough?
In our country, deaths from pertussis infections dropped by more than 75% between 1922 and 1948, the year the DPT vaccine was licensed.
In 1948, the mortality rate was less than 1 pertussis death per 100,000 persons and would never be higher than that again in the U.S. 88 89
In 2013, there were about 29,000 reported pertussis cases and 13 pertussis-related deaths in America, with 9 of those deaths in infants under age one. 90
By the end of 2024, there had been more than 35,000 pertussis cases reported in the U.S. out of 326 million people, with 10 related deaths, and 6 of those deaths in infants under age one. 91
However, reported numbers of pertussis cases do not match the total number of actual cases of pertussis that are happening in America.
Most pertussis cases, like most vaccine reactions, are not being diagnosed or reported by doctors to the government.92 93
Public health officials admit they still don’t have reliable lab tests to measure pertussis immunity, and, although there have been recent improvements in diagnostic tests, there is little agreement about how to diagnose pertussis when infected people, especially vaccinated people, show up in doctors’ offices with mild symptoms. 94 95 96
The truth is that the child or adult sitting next to you in the bus, classroom, movie theater or doctor’s office, who has a little cough or no cough at all, could be infected with B. pertussis whooping cough, even though he or she has gotten every federally recommended dose of pertussis vaccine.
U.S. Pertussis Cases in Vaccinated Persons Not Identified or Reported
When people can have silent asymptomatic infections, it means that reported cases of infectious diseases, like pertussis, are just the tip of a very big iceberg. 97
It means that articles blaming whooping cough cases on unvaccinated or partially vaccinated children are nothing more than wishful thinking and scapegoating. 98 99
BOTTOM LINE:
Naturally acquired and vaccine-acquired immunity are not lifelong.
The B. pertussis microbe circulates among both vaccinated and unvaccinated individuals.
While vaccination may prevent clinical symptoms, it does not reliably block infection, carriage, or transmission.
If vaccinated people can get silently infected and transmit infection without showing any symptoms – even after getting four to six pertussis shots - then the idea of pertussis vaccine-acquired “herd immunity” is an illusion and always has been.
So why has more than a century of pertussis vaccination failed to produce vaccine-acquired herd immunity, as public health officials insist that theoretically it can if only more and more pertussis shots are given to more people more of the time?
Extremely Reactive DPT and Less Reactive DTaP both Have Low Efficacy
The emerging scientific evidence is compelling: the B. pertussis microbe has evolved over the past century to evade whole-cell and acellular pertussis vaccines, which drug companies have marketed and medical doctors have aggressively promoted in a crusade to eradicate a species of bacteria they still know very little about. 100 101 102
A review of the medical literature reveals that the experts are unhappy with how much they still don’t know about the B. pertussis microbe and are arguing with each other about if, when, how and why pertussis vaccines have consistently failed to do the job of preventing B. pertussis whooping cough from circulating in highly vaccinated populations around the world. 103 104
The inconvenient set of scientific facts they have to work with is these:
FACT: The efficacy of whole cell pertussis vaccine in the DPT shot was measured to be between 30 and 85%, depending upon the type of DPT and vaccine manufacturer, 105 106 107 108 and protection on average lasted 2 to 5 years. 109
FACT: After a low of about 1,000 cases of pertussis were reported in the U.S in 1976, 110 it was obvious all through the 1980s and 90s that whole cell pertussis vaccine in DPT shots was not reliably preventing infection or transmission of whooping cough. 111 112 113 114 115
Pertussis cases increased in highly vaccinated populations in cycles of 3 to 5 years, 116 - just like before DPT vaccine was widely used in the 1950s. 117 118 119 120FACT: The whole cell DPT vaccine used until the late 1990’s in the U.S. was an extremely reactive vaccine.
DPT vaccine reactions like fever, pain, and irritability were experienced by between 50 and 85% of children, and seizures and collapse/shock reactions followed one in 875 DPT shots. 121 122
Brain inflammation was reported following 1 in 110,000 DPT shots with permanent brain damage after 1 in 310,000 DPT shots. 123 124
Finally, in 1996, the marginally effective and extremely reactive whole-cell DPT vaccine was replaced with a far less reactive but marginally effective acellular DTaP vaccine. 125
Similar to whole-cell pertussis vaccines, acellular pertussis vaccine efficacy in clinical trials was measured to be between 40 and 89%, depending on the DTaP vaccine manufacturer. 126 127 128FACT: Acellular pertussis vaccines do not reliably prevent infection,129 130 just like whole cell pertussis vaccines do not reliably prevent infection. 131
In the 21st century, pertussis outbreaks and cyclical increases have continued, 132 – even after a pertussis booster shot was added to the schedule for all adolescents and adults in 2006. 133 134
By 2010, the Tdap pertussis booster shot was found to be only about 66% effective in providing temporary immunity for teenagers and adults. 135
Pertussis Microbe Evolved to Evade Both DPT and DTaP Vaccines
In 1998, molecular biologists and other basic science researchers began warning that the B. pertussis microbe started to evolve to evade whole whole-cell pertussis vaccine after DPT shots were given on a mass basis to children in the 1950s. 136 137 138 139 140
These bench scientists have been publishing hard evidence that during the past 65 years, B. pertussis bacteria have efficiently adapted to both whole-cell and acellular pertussis vaccines. 141 142 143
New Pertussis Strains with More Toxin Causing More Serious Disease
In a fight to survive, some evidence suggests the B. pertussis microbe has created new strains that produce more pertussis toxin to suppress the human immune system and cause more serious disease. 144
Today, the pertussis strains included in the vaccine provide less of a match for the pertussis strains causing whooping cough disease. 145 146 147 148
BOTTOM LINE:
There is scientific evidence that B. pertussis bacteria have evolved to survive vaccine pressure, and there is some concern that more virulent pertussis strains may evolve to be more efficiently transmitted by vaccinated children and adults with waning immunity.
As one research scientist commented in 2009,
“An important question is whether other childhood vaccines also select for pathogens that are more efficiently transmitted by primed hosts, resulting in increased virulence.” 149
New Genetically Engineered Pertussis Vaccines: The Cure Worse Than the Disease?
The crusade by public health officials to eradicate the B. pertussis microbe by adding more and more doses of ineffective vaccines to the child and adult schedule – even invading the once sacred place of the womb and insisting all pregnant women be vaccinated with pertussis containing vaccines 150 151 – has not been proven to be effective, safe or necessary. 152 153
Every vaccine comes with a risk of injury or death, which can be greater for some individuals depending upon the ancestral genes they were born with, 154 155 their epigenetic history, 156 the state of their microbiome 157 158 , and other individual biological and environmental susceptibilities. 159
As we witness a bacterial species efficiently adapting to survive a war that has been declared on it by humans, what has become painfully clear is that the history of mass vaccination has not been driven by hard science transparently shared with the people. 160
It has been driven by the politics of a Public Health Empire (aka Medical and Healthcare Industrial Complex) working a lucrative government-industry public-private business partnership to protect failed mandatory vaccination laws, while ignoring the hard science.161
Scientists are creating new pertussis vaccines using genetically modified pertussis bacteria that predictably will be fast-tracked to market in a quest to put more pressure on the B. pertussis microbe to drive it from the planet. 162
The 1st targets will be pregnant women and children.
One of these is a nasal pertussis vaccine using a lipid nanoparticle adjuvant developed with NIH funding, designed to hyperstimulate an immune response. 163
The COVID shot uses lipid nanoparticles to deliver synthetic mRNA into the body’s cells and hyperstimulate an immune response. 164 165
That controversial mRNA technology is being used to develop another new pertussis vaccine, 166 it is a technology which has been associated with more than 1.5 million COVID shot reaction reports to the Vaccine Adverse Event Reporting System known as VAERS.
Will these new genetically engineered pertussis vaccines create a cure that is worse than the disease?
In 1960, Swedish scientist Justis Strom, MD, wrote in the British Medical Journal that there were more complications from the pertussis vaccine than there were complications from reported cases of pertussis in Sweden. He said: 167
The increasingly mild nature of whooping cough and the very low mortality in this disease in Sweden make it questionable whether universal vaccination against it is justified. This same question may perhaps arise in some other countries.
CALL TO ACTION: Show Us the Science and Give Us A Choice
Whatever the pharmaceutical industry and public health officials choose to do, it is up to each one of us to remind lawmakers that it is their responsibility to show us the science and give us a choice when it comes to vaccines, especially when the National Childhood Vaccine Injury Act of 1986 has been destroyed by Congress and by federal agency rule making and by the U.S. Supreme Court so that no vaccine manufacturer, no public health official and no doctor is liable in a civil court of law when vaccine reactions or failures lead to injury and death. 168
Voluntary, informed consent to medical risk taking, including to vaccination, is a human right. 169
