In 2001, Andrew Read, evolutionary biologist at Penn State University, and colleagues published a paper stating that imperfect vaccines, which protect the host from death but allow infection and disease transmission to other hosts, may actually trigger the evolution of more virulent forms of the disease.1

"Vaccines rarely provide full protection from disease," the study's abstract begins... and those that are imperfect or "leaky" may protect the host from succumbing to the disease while still allowing them to shed the virus into the community.

Ordinarily, a particularly lethal or "hot" virus is self-limiting because it will kill those it infects relatively quickly, before they have a chance to spread the virus to those around them. With leaky vaccines, this is no longer the case, as infected hosts may spread the lethal virus for weeks or more. In 2001, they wrote:2
The subsequent evolution leads to higher levels of intrinsic virulence and hence to more severe disease in unvaccinated individuals. This evolution can erode any population-wide benefits such that overall mortality rates are unaffected, or even increase, with the level of vaccination coverage."

The 2001 study was based on a mathematical model, and it was met with criticism and controversy, as are most studies that point out the imperfect nature of vaccinations or call for more research.

Now, however, Dr. Read and his colleagues have further proof of their leaky vaccine theory, this time based on the spread of Marek's disease in chickens.

'Leaky' Vaccines Can Enhance the Transmission of Highly Virulent Virus Strains

The researchers speculated that vaccines that keep hosts alive but still allow infection and transmission could allow very virulent strains of viruses to circulate in a population. This, they found, is precisely the case when chickens are immunized against Marek's disease caused by a herpes virus that is often lethal to chickens.3

In unvaccinated chickens, the most virulent strains of Marek's disease burn out on their own because the hosts are killed quickly and have little time to spread the disease.

However, when the researchers tested the virulent virus strains in vaccinated birds, they found they were infected and survived but shed the virus for much longer and therefore passed it on to far more birds. They wrote:
"Immunity elicited by direct vaccination or by maternal vaccination prolongs host survival but does not prevent infection, viral replication, or transmission, thus extending the infectious periods of strains otherwise too lethal to persist.

Our data show that anti-disease vaccines that do not prevent transmission can create conditions that promote the emergence of pathogen strains that cause more severe disease in unvaccinated hosts."

This is added proof that long-term use and overuse of vaccines could present real problems for individual and public health by ultimately allowing highly virulent diseases to spread and persist in the community.

Is Whooping Cough Vaccine Also 'Leaky?'

Your health care provider probably won't tell you that certain vaccines may be imperfect and that if you or your child get vaccinated, you can still potentially become infected and transmit infection to other vaccinated and unvaccinated people.

Some of the experimental viral vaccines in development, such as those against malaria, Ebola and HIV/AIDS, as well as those used for animal diseases like avian flu, may be leaky. However, some of the older "standbys" including bacterial vaccines like pertussis (whooping cough) vaccine may also be "leaky." Dr. Read told Forbes:4
"The whooping cough vaccine appears to leak... That's an evolutionary experiment in the making."
The pertussis (whooping cough) vaccine is included as a component in "combination" shots that include tetanus and diphtheria (DPT, DTaP, and Tdap) and pertussis vaccine is also in combination shots that contain inactivated polio, hepatitis B, and/or Haemophilus Influenza B (Hib) vaccines.

US Centers for Disease Control and Prevention (CDC) data shows that 84 percent of children under the age of three have received at least FOUR DTaP shots — which is the acellular pertussis vaccine that was approved in the US in 1996.

Nationally, about 95 percent or more of children entering kindergarten have received four or five DTaP shots and yet, despite this very high vaccination rate, B. pertussis whooping cough still keeps circulating among both vaccinated and unvaccinated children and adults.

Comment: Why vaccines spread disease and vaccine science is flawed
In an extensive rebuttal to a 2012 article written by Forbes' Steven Salzberg that blamed a whooping cough outbreak in the Northwest on unvaccinated children, Dr. Paul G. King, Ph.D., of FAME Systems deconstructed the popular misconception that infectious disease reemergence is the result of people not getting vaccinated. On the contrary, it is the vaccination schedule itself, which the federal government has been coercing people into complying with for nearly the entire last century, that is ultimately leading to and driving these outbreaks.

"Salsberg is simply using a longstanding 'straw man' created long ago by his fellow vaccine apologists to divert the public's attention from the reality that... the current pertussis vaccines are neither effective in providing those inoculated with them long-term protection from contracting whooping cough nor... cost effective," explains Dr. King in his paper.

A PNAS study published earlier this year argued that if vaccines are leaky, which in this case referred to vaccines not entirely protecting an individual from infection and ability to transmit infection to others, even current booster schedules will be ineffective.5 They wrote:
"Especially notable is the inability of booster schedules to alleviate resurgence when vaccines are leaky. Critically, our findings argue that the ultimate effectiveness of vaccine booster schedules will likely depend on correctly pinpointing the causes of resurgence, with misdiagnosis of the problem epidemiologically ineffective and economically costly."
In 2013, the US Food and Drug Administration (FDA) discovered that while the whooping cough vaccine may reduce symptoms in those who are vaccinated, the pertussis vaccine does not prevent infection and transmission of the disease.

In fact, you can get five or six pertussis-containing shots and still become an asymptomatic carrier who is contagious and can spread the disease to others without even knowing it. That FDA study published two years ago effectively shattered the long-held illusion of vaccine-induced herd immunity.

Mumps Vaccine Isn't Working Well Either

For more evidence that mass, mandatory vaccination does not always work the way the public has been told it does by public health officials and vaccine manufacturers, consider that in December 2014, more than a dozen NHL hockey players contracted mumps, despite having received their childhood MMR (measles-mumps-rubella) vaccinations.

Gregory Poland, director of the Mayo Clinic's Vaccine Research Group told Forbes there are three likely factors at play:6
  1. Waning immunity
  2. The vaccine's initial effectiveness (or lack thereof)
  3. The quality of the individual vaccine given
According to the CDC,7 one dose of the MMR vaccine has a disease prevention rate of 78 percent, so right off the bat you know it's not going to prevent disease in everyone. A second dose is claimed to increase protection to 88 percent. But outbreak rates suggest the vaccine's effectiveness wears off, and might be lower than expected to begin with.

In 2010, two Merck virologists filed a federal lawsuit under the False Claims Act against their former employer, alleging the vaccine maker has been lying about the effectiveness of their mumps vaccine (which is part of the trivalent MMR vaccine). The whistleblowers claimed they witnessed "first hand the improper testing and data falsification in which Merck engaged to artificially inflate the vaccine's efficacy findings."

Merck allegedly falsified the data to hide the fact that the mumps vaccine in the MMR shot has in fact significantly declined in effectiveness over the years. Still, a lowered disease complication and mortality risk might still sound like a good thing, even if total protection can't be guaranteed.

But if bacteria and viruses are evolving to not only become vaccine resistant, mirroring what we're seeing with growing microbe resistance to antibiotics, but microbes are also becoming more virulent as the vaccinated survive and are able to transmit infection for longer periods of time to both the unvaccinated and vaccinated, then the entire mandatory vaccination program would need a serious review.

What if we're misusing vaccines like we've misused antibiotics and compromising human immune function while creating far more serious diseases in the process? This is a question that deserves much more attention by public health officials and needs to be answered quickly.

Vaccines Increase Narcolepsy Risk, Media Blames 'Anti-Vaxxers' for Their Lack of Fair Reporting

Vaccines can and do cause serious side effects, including permanent brain and immune system injury and death, but rather than acknowledge that fact and move forward to figure out why it happens and who is most at risk, many studies that investigate and report on vaccine risks are often swept under the rug.

The swine flu (H1N1) vaccine (Pandemrix), for instance was causally linked to an increased risk of narcolepsy among children and adolescents.8 About 1,000 people who received the swine flu shot developed the neurological disorder, and will live with it the rest of their lives.

If this is news to you, it's probably because few media outlets picked up on this story at the time, and a recent article in Vox readily admits that many reporters "shy away" from writing about uncertainty in vaccine science.9

Rather than report fairly on a pressing issue that the public deserves to be informed of, the Vox author admits she "ignored the Pandermix study, too," even though she knew the author of the study is "an extremely credible scientist" and that "her results didn't come in isolation."

To justify her bias that resulted in unfair and inaccurate reporting, this journalist blamed "anti-vaxxers" for "scaring the media away from covering vaccine side effects.10 And it gets even more outrageous, because she then goes on to describe a sort of bizarre formula for how reporters are supposed to report on studies showing vaccines might cause side effects or lack effectiveness.

The "rules" include that it's ok to be skeptical of newer vaccines but not of older established ones. She also frowns on giving equal weight to both sides of an issue that aren't actually equal, such as daring to suggest there might be controversy among scientists regarding a vaccine's safety. But then, at the same time, you should "avoid cheerleading for vaccines," lest you appear too one-sided.

Whatever happened to simply reporting the facts, asking the questions that need to be asked and letting the reader decide what to think?

CDC Scientists Claims CDC Covered Up MMR-Autism Connection Public health agencies and, certainly, pharmaceutical companies would like you to believe the book is closed regarding vaccine safety - but really it is only starting to be opened. Methodologically sound studies have not been done to determine whether children vaccinated according to the CDC's vaccine schedule are healthier or sicker than those who are not vaccinated. Further, there is almost no basic science research into the genetic, biological, and environmental high risk factors that make some people more vulnerable to vaccine harm.

Even hotly debated topics, like the potential vaccine-autism connection, have not been thoroughly explored. Perhaps this is because when a study provides evidence that vaccines can cause harm, the researchers are often ostracized or journals refuse to publish the data.

Hanna Nohynek, a vaccine researcher with the Finnish government, for instance, conducted some of the early research regarding the connection between swine flu vaccine and narcolepsy. The New England Journal of Medicine, BMJ, and The Lancet all refused to publish her work.11

Dr. William Thompson, a research scientist at the CDC's National Center for Immunizations and Respiratory Diseases (NCIR) has claimed that the CDC covered up a vaccine-autism connection in relation to the MMR vaccine. The study reportedly discovered that African-American boys who received the MMR vaccine before the age of 36 months had an increased risk for autism.

Dr. Thompson states the study co-authors then:
"scheduled a meeting to destroy documents related to the study. The remaining four co-authors all met and brought a big garbage can into the meeting room, and reviewed and went through all the hardcopy documents that we had thought we should discard, and put them into a huge garbage can."12
Dr. Thompson has stated that he retained the hard copies in the event a "neutral investigative or scientific body" would like to see it. However, as Sharyl Attkisson reported:13
"Despite this whistleblower testimony, which Dr. Thompson provided to Rep. Bill Posey, R-Florida, there is little chance of a meaningful hearing or investigation. In an untainted news environment, the allegations would make headlines in most legitimate publications and would trigger federal inquiries. However, the interests of the powerful pharmaceutical industry reach deeply into Congress and the news media through lobbyists, propaganda and advertising dollars."
Vaccine Side Effects Must Not Be Swept Under the Rug A different take on the issue was published in the Philly Voice, in which the reporter noted a need for mainstream media to make space for the very real cases of vaccine-induced illness, injury and death. The reporter writes:14
"... [A] new medical textbook, entitled Vaccines and Autoimmunity was published.15 Featuring the work of dozens of scientists and physicians, the text was edited by Yehuda Shoenfeld, founder of Israel's Center for Autoimmune Diseases; Nancy Agmon-Levine [sic], President of the Israel Association for Allergy and Clinical Immunology; and Lucija Tomljenovic, a senior post-doctoral fellow at the University of British Columbia.

In their introduction to Vaccines and Autoimmunity, the editors acknowledge that vaccines can trigger 'severe and even fatal' reactions in certain individuals and that this is of particular concern as vaccines are 'administered to healthy individuals.'

The editors raise questions about the trace amounts of 'residuals' - such as monkey kidney tissue, detergents, and preservatives - whose safety 'has not been thoroughly investigated' and decry the naïve assumption that 'all humans are alike' in their immunological reactions to vaccinations. They continue: "... the fact that vaccines are delivered to billions of people without preliminary screening for underlying susceptibilities is thus of concern."
The article points out that the stories of vaccine-injured children matter, but often the parents of vaccine-injured children feel bullied for speaking out. Many Americans are not even aware that there is a Vaccine Adverse Events Reporting System (VAERS), which is to be notified of vaccine reactions, or that there is a federally operated vaccine injury compensation program (VICP) that handles contested vaccine injury and death cases. As reported in the Philly Voice:16
"It behooves every American parent to be informed about the existence of VAERS and available government compensation should one's child suffer due to a vaccine. The majority of us who walk away from a routine pediatric visit unscathed would be wise to stay abreast of vaccine injury rates, support adverse reaction prevention efforts, and most importantly, remain open to the suffering of those who experience vaccine injuries or death.
Protect Your Right to Informed Consent and Defend Vaccine Exemptions

With all the uncertainty surrounding the safety and efficacy of vaccines, it's critical to protect your right to make independent health choices and exercise voluntary informed consent to vaccination. It is urgent that everyone in America stand up and fight to protect and expand vaccine informed consent protections in state public health and employment laws. The best way to do this is to get personally involved with your state legislators and educating the leaders in your community.


National vaccine policy recommendations are made at the federal level but vaccine laws are made at the state level. It is at the state level where your action to protect your vaccine choice rights can have the greatest impact. It is critical for EVERYONE to get involved now in standing up for the legal right to make voluntary vaccine choices in America because those choices are being threatened by lobbyists representing drug companies, medical trade associations, and public health officials, who are trying to persuade legislators to strip all vaccine exemptions from public health laws.

Signing up for NVIC's free Advocacy Portal at gives you immediate, easy access to your own state legislators on your smart phone or computer so you can make your voice heard. You will be kept up-to-date on the latest state bills threatening your vaccine choice rights and get practical, useful information to help you become an effective vaccine choice advocate in your own community. Also, when national vaccine issues come up, you will have the up-to-date information and call to action items you need at your fingertips.

So please, as your first step, sign up for the NVIC Advocacy Portal.

Share Your Story with the Media and People You Know

If you or a family member has suffered a serious vaccine reaction, injury, or death, please talk about it. If we don't share information and experiences with one another, everybody feels alone and afraid to speak up. Write a letter to the editor if you have a different perspective on a vaccine story that appears in your local newspaper. Make a call in to a radio talk show that is only presenting one side of the vaccine story.

I must be frank with you; you have to be brave because you might be strongly criticized for daring to talk about the "other side" of the vaccine story. Be prepared for it and have the courage to not back down. Only by sharing our perspective and what we know to be true about vaccination will the public conversation about vaccination open up so people are not afraid to talk about it.

We cannot allow the drug companies and medical trade associations funded by drug companies or public health officials promoting forced use of a growing list of vaccines to dominate the conversation about vaccination. The vaccine injured cannot be swept under the carpet and treated like nothing more than "statistically acceptable collateral damage" of national one-size-fits-all mandatory vaccination policies that put way too many people at risk for injury and death. We shouldn't be treating people like guinea pigs instead of human beings.

Connect with Your Doctor or Find a New One That Will Listen and Care

If your pediatrician or doctor refuses to provide medical care to you or your child unless you agree to get vaccines you don't want, I strongly encourage you to have the courage to find another doctor. Harassment, intimidation, and refusal of medical care is becoming the modus operandi of the medical establishment in an effort to stop the change in attitude of many parents about vaccinations after they become truly educated about health and vaccination.

However, there is hope.

At least 15 percent of young doctors recently polled admit that they're starting to adopt a more individualized approach to vaccinations in direct response to the vaccine safety concerns of parents. It is good news that there is a growing number of smart young doctors, who prefer to work as partners with parents in making personalized vaccine decisions for children, including delaying vaccinations or giving children fewer vaccines on the same day or continuing to provide medical care for those families, who decline use of one or more vaccines.

So take the time to locate a doctor, who treats you with compassion and respect and is willing to work with you to do what is right for your child.
