Did Trump Lay the Groundwork to Ban Mandatory Vaccinations?

Have you heard that Donald Trump is going to ban mandatory vaccinations?

Or that he is going to ban childhood vaccinations all together?

Guess what?

That’s right, neither is true.

Did Trump Lay the Groundwork to Ban Mandatory Vaccinations?

To be sure, anti-vaccine folks were likely excited when Donald Trump was elected President.

Donald Trump's vaccine and autism tweet.

In addition to his tweets that tried to associate vaccines with autism, there were reports that he was going to set up a committee on vaccine safety that would be headed by Robert F Kennedy, Jr!

So the idea that he might try to ban vaccines was probably thought of as a safe bet for some.

Fortunately, it wasn’t.

Which vaccines kids need to go to daycare and school are mandated by state law. Despite what some folks might think, there are no federal vaccine mandates.

While there is a new a new Conscience and Religious Freedom Division in the HHS Office for Civil Rights, it doesn't ban vaccinations.
While there is a new Conscience and Religious Freedom Division in the HHS Office for Civil Rights, it doesn’t ban vaccinations.

And even with the announcement of a new Conscience and Religious Freedom Division in the HHS Office for Civil Rights (OCR), there is no ban on mandatory vaccinations across the United States.

“The creation of the new division will provide HHS with the focus it needs to more vigorously and effectively enforce existing laws protecting the rights of conscience and religious freedom, the first freedom protected in the Bill of Rights.”

HHS Announces New Conscience and Religious Freedom Division

Could you interpret this is laying the groundwork for allowing religious exemptions to vaccines?

Again, vaccine mandates are set by state law, so no, you shouldn’t. Anyway, almost all states already allow religious exemptions to getting vaccinated, even though no major religion is actually against vaccinating and protecting kids from life-threatening vaccine-preventable diseases.

“Conscience protections apply to health care providers who refuse to perform, accommodate, or assist with certain health care services on religious or moral grounds.”

Conscience Protections for Health Care Providers

A proposed rule, Protecting Statutory Conscience Rights in Health Care; Delegations of Authority, that might have affected vaccines funded by Federal medical assistance programs, never took effect. In fact, the White House urged HHS to not finalize the rule after the Office of Management and Budget said they weren’t complying with necessary rules to get it implemented on time.

 “The AAP wishes to underscore its recognition of the important role of religion in the personal,spiritual, and social lives of many individuals, including health providers. Balancing that role with efforts to ensure children have appropriate access to needed health and social services is critical to meeting their health needs and supporting their health and well being. As HHS considers potential changes to regulations and policy guidance to encourage the provision of grants and contracts to faith-based organizations, we urge you to ensure that federal policy does not undermine children’s access to needed care and services.”

Collen Kraft, MD, FAAP, President of the American Academy of Pediatrics

Not surprisingly, major medical associations were against the proposed rule, and not just because of potential effects on vaccines, even though it wouldn’t have actually banned vaccines.

“The proposal would dramatically expand the discretion that religious or moral objectors have to refuse care without meaningful safeguards to ensure that the rights of those receiving care are protected.”

AMA on HHS should withdraw proposal on health care conscience rights

Sadly, as Kennedy and many anti-vaccine folks focus and what they think are toxins and poisons in vaccines, they seem to be ignoring the fact that Donald Trump is going to expose our kids to many more real toxins and poisons through his efforts to slash Clean Water Act protections and other EPA regulations.

At least we can look forward to no bans on mandatory vaccines, even though many parents continue to abuse existing vaccine exemptions, putting us all at risk.

Who Is Judy Mikovits?

Dr. Judy Mikovits has a PhD in Biochemistry and Molecular Biology, doing her thesis on Negative Regulation of HIV Expression in Monocytes.

She had several papers published with Dr. Frank Ruscetti, with whom she continues to work.

Instead of research, it seems that they now do:

  • Advocacy for vaccine injury legal cases worldwide. 
  • Research and documentation on medical exemptions for vaccinations.

What happened?

Who Is Judy Mikovits?

After working at the National Cancer Institute, it seems that Judy Mikovits became research director of the Whittemore Peterson Institute (WPI).

A paper by Mikovits and Ruscetti was retracted because no one else could replicate the work.

She was eventually fired after a paper she was lead author on, which found xenotropic murine leukemia virus-related virus (XMRV) in patients with CFS, was retracted and the institute accused her of stealing notebooks and manipulating data.

“But the leader of the team that authored the 2009 paper, researcher Judy Mikovits, apparently presented the same figure — carrying different labels and supporting a different point — in a talk given at a conference on Sept. 23 in Ottawa.”

Manipulation alleged in paper linking virus, chronic fatigue syndrome

An even larger study found no evidence of XMRV infections in patients with chronic fatigue syndrome, even as she had claimed the virus could cause CFS, Parkinson’s disease, autism and multiple sclerosis.

The source of XMRV in her patients?

“Well-controlled experiments showed that detection of XMRV was due to contaminated samples and was not a marker of or a causal factor in prostate cancer or CFS.”

Johnson et al on Xenotropic Murine Leukemia Virus-Related Virus (XMRV) and the Safety of the Blood Supply

The virus was in a contaminated cell line in which she and others were doing research. The virus wasn’t in the actual patients themselves.

Judy Mikovits on Vaccines

Before her paper was retracted and she was fired from her lab, Judy Mikovits did actually do research on viruses and she is a scientist. She didn’t do research on vaccines though.

Judy Mikovits is still finding retroviruses wherever she looks for them...
Judy Mikovits is still finding retroviruses wherever she looks for them…

That seems to be something she talks about a lot now though:

  • at anti-vaccine rallies
  • at anti-vaccine conferences
  • in anti-vaccine videos

Her claim to fame seems to be talking about contaminated vaccines and bashing Gardasil. And deep state conspiracy theories about why she was arrested and lost her job.

To be clear, a rotavirus vaccine was found to be contaminated with DNA of porcine circovirus type 1.  While that might sound a little scary, it is important to keep in mind that the PCV1 virus doesn’t actually cause disease in people and these weren’t even “biologically active virus particles.”

PCV1 isn’t a retrovirus though and Judy Mikovits wasn’t even the researcher who discovered the contamination, which has since been resolved. 

“These findings do not indicate the presence of either ALV or EAV infection in MMR vaccine recipients and provide support for current immunization policies.”

Hussain et al on Lack of Evidence of Endogenous Avian Leukosis Virus and Endogenous Avian Retrovirus Transmission to Measles Mumps Rubella Vaccine Recipients

Studies have looked at retrovirus contamination of vaccines, but they were  done over 17 years ago. And not by Mikovits. Studies that confirmed that vaccines are safe.

None of this has kept Judy Mikovits from scaring people about vaccines, especially the HPV vaccine.

“Cervical cancer is not a public health threat. It’s not an infectious disease. Why is it in the Department of Public Health? Why are we mandating every child over 9 years old, and I heard soon to be pregnant women, to get this vaccine? It makes no sense.”

Judy Mikovits

It is really hard to understand how someone who worked at the National Cancer Institute could make these statements. Cervical cancer is one of the most common cancers in women.

There is, of course, no mandate for 9-year-olds to get the HPV vaccine. In the United States, HPV vaccination is recommended, beginning at age 11 to 12 years. The HPV vaccine is not recommended for pregnant women and while several vaccines are recommended, no vaccines are actually mandated in pregnancy.

“It was never developed to prevent cancer. It was developed and approved to prevent warts. Warts are not a public health threat. It’s beyond… When scientists like myself, and I work in cancer and AIDS hear this, we are just…”

Judy Mikovits

Gardasil and Cervarix were developed to prevent HPV infections, which cause cervical cancer. HPV can also cause genital warts.

“I think we need to ban… Japan and India have, all HPV vaccinations now, until the appropriate studies are done, until the patients are tested…”

Judy Mikovits

Neither Japan nor India have banned HPV vaccinations.

Why should we? The HPV vaccines are safe, effective, and necessary.

And why would anyone listen to Judy Mikovits?

Who was Betty Bumpers?

Only when every child has completed his or her series of immunizations will our job be completed.

Even as some schools and communities continue to face outbreaks of measles, chicken pox, and other vaccine-preventable diseases, there is a very good chance that your kids are in a school where you don’t have to worry about them getting sick.

There is also a good chance that you have no idea who made that possible.

Who was Betty Bumpers?

Sure, a lot of it has to do with all of the parents who are making the right choice in vaccinating and protecting their kids.

And of course, there are the folks who actually developed the vaccines.

But there was a time when we had many vaccines and kids still weren’t getting protected.

“I don’t think that there is anything more important than immunizing our children and preventing unnecessary suffering. We’ve seen too much of that and it’s been so exciting now to see immunization rates going up. Betty Bumpers and I have worked on this for a long time, but Betty Bumpers is the real hero. She has done more for immunizations than any one person in this whole country.”

Former First Lady Rosalynn Carter

That changed in the early 1970s, when Betty Bumpers, as the First Lady of Arkansas, worked to raise immunization rates in her state, with the Every Child By ’74 campaign.

The Every Child in '74 immunization program immunized over 300,000 children in Arkansas.
The Every Child in ’74 immunization program immunized over 300,000 children in Arkansas.

She didn’t stop in Arkansas though.

“I believe our program, based upon volunteers and government agencies already in pace, has been tremendously successful.”

Betty Bumpers

In 1975, she told a Senate subcommittee that her immunization program could serve as a model for other states too.

“Measles incidence declined dramatically after large vaccination campaigns, but transmission was not interrupted. The licensure of rubella vaccine in 1969 led to mass campaigns to immunize children to avert an anticipated repeat of the tragic epidemic of 1964–65, which resulted in the births of approximately 20,000 infants with congenital rubella syndrome. The rubella campaigns diverted attention and funding from measles, resulting in a resurgence of measles. Federal funding for Section 317 declined during the early to mid-1970s. Immunization coverage fell, and disease increased.”

Vaccine-Preventable Diseases, Immunizations, and MMWR — 1961–2011

A few years later, President Jimmy Carter announced the National Childhood Immunization Initiative of 1977, a program that was stimulated by the efforts of Betty Bumpers, with Rosalynn Carter.

In addition to increased spending on immunization programs, we soon had laws in every state requiring students to be vaccinated before they could attend school, and not surprisingly, measles cases quickly dropped.

It didn’t last.

Without support for immunization programs from the Reagan administration, vaccination rates dropped and measles cases soared.
The Role of Measles Elimination in Development of a National Immunization Program

In the year’s that followed the Carter administration, Federal support for vaccine programs reached a low point, as rates of children living in poverty and without health insurance also increased.

To help combat this rise in vaccine-preventable disease, Betty Bumpers, again with Rosaylnn Carter, launched Every Child By Two – Carter/Bumpers Champions for Immunization.

Founded in 1991, Every Child By Two, now Vaccinate Your Family, has worked to raise awareness about the importance of getting vaccinated on time and on schedule. This was especially important at the time, when many preschool age kids weren’t getting vaccinated. And it still is, as misinformation about vaccines continues to scare some parents away from vaccinating and protecting their kids.

She also worked with her husband, Senator Dale Bumpers, to encourage Bill Clinton’s administration to develop the Childhood Immunization Initiative, which he proposed in 1993, and to pass the Vaccines for Children Program, which was created by the Omnibus Budget Reconciliation Act of 1993.

The Dale and Betty Bumpers Vaccine Research Center wad dedicated in 1999.

In addition to her work helping get kids vaccinated, Betty Bumpers:

She is truly a hero and should be remembered for all of the work she did.

Whether folks understand it or not, it is because of the work of Betty Bumpers that even as some folks skip or delay their child’s vaccines, the outbreaks they cause are eventually contained before they get out of control.

Betty Bumpers was a champion in our efforts to reduce the burden of vaccine-preventable diseases among children in the United States.  She played a major leadership role as 1st Lady of Arkansas in improving immunization in that state and was inspirational in launching the first major Presidential Initiative on Immunization during the late 1970s.  She continued to be a major immunization advocate through much of her life launching “Every Child By Two (ECBT)” which she chaired along with Mrs. Rosalyn Carter, now “Vaccinate Your Family”.

Walter Orenstein

That work will continue to save the lives of millions of children, at least it will as long as we don’t let folks chip away at it, allowing them to abuse exemptions and spread propaganda, scaring parents away from vaccinating and protecting their kids.

That’s why we all must continue her work

For as Betty Bumpers said, “only when every child has completed his or her series of immunizations will our job be completed.”

Is the La Leche League Anti-Vaccine?

Why would anyone think that the La Leche League, an organization who’s mission is to support breastfeeding, might be against vaccines?

“Many parents have questions about the compatibility of vaccines and breastfeeding. Your healthcare provider can address any questions that come up for you.”

la leche league international on Vaccines

They certainly don’t make any strong statements supporting vaccines…

“The LLLI Health Advisory Council suggests families discuss the pros and cons of influenza vaccines with their health care practitioners.”

la leche league international on Influenza

The cons of influenza vaccines?

What are those exactly? That the protection babies get from their mother’s pregnancy flu shot doesn’t last until they go to college?

What’s the greatest evidence that they might not support vaccines? I mean, besides anti-vaccine La Leache League leaders who actively say that they are against vaccines?

Bob Sears is giving two lectures  on vaccines at an upcoming La Leche League breastfeeding conference.
What exactly will Bob Sears be talking about during his two lectures on vaccines at this upcoming La Leche League breastfeeding conference?

Bob Sears is giving two lectures on vaccines at an upcoming La Leche League breastfeeding conference.

Will he really discuss the benefits of vaccines for pregnant and post-partum mothers and their families?

“Dr. Bob Sears, a renowned Dana Point pediatrician who has been sought out by parents who wish to opt out of the state’s mandatory vaccine requirements, has been placed on probation for 35 months by the Medical Board of California.”

Dr. Bob Sears, renowned vaccine skeptic, placed on probation for exempting child from all vaccinations

And considering that he nearly lost his medical license over giving an improper vaccine exemption, what can we really expect from his talk on California’s vaccine law?

“Remember that La Leche League is exclusively focused on breastfeeding support and has no stance on vaccinations.”

La Leche League USA

No stance on vaccinations?

Actually, with bringing Dr. Bob to their conference, it seems like they made a very clear stance…

“Nursing also allows your baby to give germs to you so that your immune system can respond and can synthesize antibodies! This means that if your baby has come in contact with something which you have not, (s)he will pass these germs to you at the next nursing; during that feeding, your body will start to manufacture antibodies for that particular germ. By the time the next feeding arrives, your entire immune system will be working to provide immunities for you and your baby. If you are exposed to any bacteria or viruses, your body will be making antibodies against them and these will be in your milk.”

Can Breastfeeding Prevent Illnesses?

And they have also done a good job of making it sound like breastfeeding infants don’t need vaccines.

They do!

While breastfeeding is great, it is not a substitute for getting vaccinated. In fact, antibodies in breast milk will not protect a baby against most vaccine-preventable diseases.

If the La Leche League truly wants to support what’s best for kids, they should move away from pushing non-evidence based therapies, especially craniosacral therapy and referrals to chiropractors for breastfeeding problems, and they should take a stand supporting vaccines.

The La Leche League is on this list of other organizations that speak out against vaccines.

Anti-Vaxxers Should Be Able to Answer These Questions Correctly

There is a new meme going around suggesting that folks have no business telling anyone to vaccinate and protect their kids unless they can answer a series of questions.

I bet answers from anti-vaccine folks aren't the same as the answers from the rest of us...
I bet answers from anti-vaccine folks aren’t the same as the answers from the rest of us…

While it is certainly good to be educated about vaccines, their questions seem rather loaded.

Anti-Vaxxers Should Be Able to Answer These Questions Correctly

Since it is immoral and dangerous to push misinformation that scares parents away from vaccinating and protecting their kids, it would be nice if anti-vaccine folks would answer these questions before they tried to persuade anyone to not get vaccinated:

  1. Name 5 vaccine ingredients that you think are toxic and how exactly they can be toxic at the amounts present in vaccines.
  2. Name 5 possible complications of a vaccine-preventable disease.
  3. Are doctors and alternative health care providers who push non-standard, parent-selected, delayed protection vaccine schedules able to be held liable if their intentionally unvaccinated child suffers a vaccine-preventable disease or starts an outbreak, infecting other people?
  4. How many children died of vaccine-preventable diseases in the early 1980s, before the vaccine schedule grew to include the new vaccines we give today?
  5. Is it true that no one can force you to get vaccinated?
  6. What percentage of reports to VAERS are actually caused by vaccine reactions?
  7. How many doses of vaccines have been given since the Vaccine Court began paying for vaccine injury cases?
  8. Which vaccines must be avoided because of shedding or other concerns if you have a child with an immunodeficiency in your home?
  9. Why do some folks think that many vaccines still contain thimerosal?
  10. If today’s vaccines already contain far fewer antigens than they did in the old days, what would be the extra benefit of splitting them up even further into separate shots for each vaccine-preventable disease?
  11. Have you read all of studies on the safety and effectiveness of combination vaccines, including those that are double-blinded and placebo controlled, and the current vaccine schedule?
  12. Can you give me one other interesting fact about vaccines or vaccine-preventable diseases that was not already asked or discussed?

What’s my interesting fact?

Many on-the-fence and vaccine hesitant parents do change their mind about vaccines and decide to make the right choice and get their kids vaccinated and protected.

More Things Anti-Vaxxers Should Know

Catching up on 17 Years Worth of Vaccinations to Attend College

With the passage of California’s new vaccination law, it is not just kids in daycare, kindergarten, and high school who have to be up-to-date on their immunizations.

“If I chose to attend Berkeley, I would have to catch up on 17 years worth of vaccinations.”

Madeline Scott

Many California universities strengthened their immunization requirements at about the same time as SB 277 passed.

Does that really mean that an unvaccinated, incoming freshman would have to get 17 years worth of vaccinations?

How To Catch Up On Missing Immunizations

Of course not. Teens don’t really need to get 17 years worth of vaccinations to get caught up, even if they had never had a single vaccine before.

Why not?

They are too old for some vaccines, like those for rotavirus, Haemophilus influenzae type b (Hib), and Streptococcus pneumoniae (Prevnar).

And because they are starting so late, they would get fewer doses of a few vaccines, so most older teens could get fully caught up after getting just:

  • 1 dose of MCV4 (a meningococcal vaccine)
  • 2 or 3 doses of MenB (a meningococcal vaccine)
  • 2 doses of MMR
  • 2 doses of the chicken pox vaccine
  • 1 dose of Tdap, followed by 2 doses of Td (instead of the standard 5 doses of DTaP vaccine that younger children get, which is followed by a Tdap booster at age 12 years)
  • 2 doses of HepA
  • 3 doses of HepB
  • 3 doses of IPV (instead of the standard 4 doses of polio vaccine that younger children get)
  • 3 doses of HPV vaccine
  • a flu shot

How quickly could they get caught up?

Probably in about 8 months – the minimal interval between all of the Tdap/Td doses. Most of the rest of the vaccines can be given over a 6 month interval or even quicker.

Catching up on 17 Years Worth of Vaccinations to Attend College

Surprisingly, the University of California at Berkeley actually requires very few of these immunizations for new students though.

Students at Berkeley are much more likely to march for science than against it.
Students at Berkeley are much more likely to march for science than against it.

The only vaccines that are required include:

  • two doses of MMR
  • two doses of the chicken pox vaccine
  • one dose of the MCV4 meningococcal vaccine
  • one dose of Tdap

Using the combination vaccine ProQuad (MMR and chicken pox together), that could mean as few as 4 shots instead of “17 years worth of vaccinations.”

Of course, that leaves the student unprotected against a lot of vaccine-preventable diseases.

Other vaccines that are recommended, but not required, include those that can protect students against flu, hepatitis B, MenB, HPV, hepatitis A, polio, and pneumococcal bacteria (if high risk).

Can Vaccinated Children Be Asymptomatic Carriers of Pertussis?

Why do anti-vaccine folks like to talk about baboons so much?

“Did you know that a study showed that baboons injected with whooping cough vaccine became infected with whooping cough anyway – and silently spread the disease to other baboons for 35 days?”

Anti-vaccine Meme

Is it because baboons are used in the study of vaccines?

That’s part of it, at least when they can find a study where they can cherry pick the results to suit their needs.

The Baboon Study

Like most anti-vaccine talking points, this one about baboons, has some truth to it.

An adult male baboon.

There was a baboon study with the pertussis vaccine and it found that previously vaccinated baboons could develop asymptomatic carriage of the pertussis bacteria after they were intentionally infected.

Here is where it is important to note that an infection is different than a disease.

The example that many people are familiar with is tuberculosis. It is common to have a TB infection without any signs or symptoms and to not feel sick. The only reason we know that they have TB is because they had a positive TB test.

Unfortunately, about 5 to 10% of these people with TB infections can eventually develop TB disease, with coughing, weight loss, night sweats, fever, and chest pain, etc.

It is kind of the same with the baboons in the study. Twenty-four hours after two previously vaccinated baboons were inoculated with pertussis bacteria in the back of their nose and trachea, an unvaccinated baboon was put in each of their cages.

The vaccinated baboons continued to have pertussis bacteria in their noses, which the researchers had put there, for up to 35 days. And they were able to eventually pass the pertussis bacteria to the unvaccinated baboons in their cages. Vaccinated baboons also became infected or colonized after they were put in a cage with an intentionally infected unvaccinated baboon.

“…animals did not cough and showed no reduction of activity, loss of appetite, or other outward signs of disease.”

Warfel et al on Acellular pertussis vaccines protect against disease but fail to prevent infection and transmission in a nonhuman primate model

The vaccinated baboons were infected, but they never did develop symptoms of pertussis.

What Does The Baboon Study Mean?

One thing that is for sure – the baboon study found that the pertussis vaccines work. Only unvaccinated baboons got sick with pertussis.

But does this study explain our current outbreaks of pertussis?

Are vaccinated people becoming colonized and then getting others sick?

I guess it is possible, but we are not baboons in a cage with other baboons. How would we spread a respiratory disease, even if we did become colonized with the bacteria, if we don’t have symptoms?

It may explain part of our outbreaks though.

If vaccinated people do commonly become colonized with pertussis bacteria, then they might very well test positive for pertussis even though they don’t have symptomatic pertussis disease. So when they develop a cold or bronchitis and are found to have a positive pertussis test, then couldn’t that test just indicate that they have a pertussis infection and not disease, even though something else is actually causing their symptoms?

That’s what we think happens with strep carriers, right?

That’s kind of what the baboon study found. All of the baboons tested positive, but only the unvaccinated baboons had symptomatic pertussis disease.

“Baboons vaccinated with wP vaccines exhibit a level of protection that is intermediate between convalescent animals and aP-vaccinated animals. They exhibit no outwards signs of disease and are initially colonized to the same high level as aP-vaccinated animals but clear the infection more rapidly.”

Pinto et al on Pertussis disease and transmission and host responses: insights from the baboon model of pertussis.

It is interesting to note that the baboon study also found that baboons who had received whole cell pertussis vaccines also became carriers. They just didn’t stay carriers for as long as the baboons who got the newer acellular pertussis vaccine. But since they were still carriers, if asymptomatic transmission is such a big problem, wouldn’t it have been a big problem back in the day when everyone got whole cell pertussis vaccines?

The Debate Over Asymptomatic Carriage

Most vaccines prevent the spread of disease.

Do the pertussis vaccines?

Most folks still think so.

“The baboon model pioneered by Warfel et al. is without question a game-changer, shedding light on the impact of vaccination on disease and infection. However, the view it affords is clearer with respect to immunity and pathology than with respect to transmission. We point out that the extrapolation of the possibility of transmission from vaccinated baboons in the laboratory to the probability of transmission from vaccinated humans in the population is unwarranted. More work is needed to elucidate the relative transmissibility of infections in vaccinated vs. unvaccinated hosts. The evidence adduced above suggests, however, that vaccination with aP must have a strong effect on transmission as well as disease.”

Matthieu Domenech de Cellès et al on Epidemiological evidence for herd immunity induced by acellular pertussis vaccines

Even the author of the baboon study has said that “We agree that these data should not be directly extrapolated to pertussis transmission in humans. Although baboons are >96% genetically similar to humans, there are likely differences in how the species respond to vaccination and infection. We also agree that aP-vaccinated infected people are likely less efficient at transmitting pertussis compared with unvaccinated infected people, although it is not clear to what extent.”

Others think that asymptomatic carriage of pertussis might behind a lot of our recent outbreaks. Or at least what helps them grow so large.

Still, it is important to remember that unvaccinated folks do play a role in these outbreaks too. In a pertussis outbreak at a Florida preschool, in which most kids were vaccinated, the outbreak was started by a vaccine-exempt toddler.

And we have seen this in many other areas and it has been confirmed by many studies. Whatever else is contributing to pertussis outbreaks, like waning immunity, they are also associated with vaccine refusal.

“Counties with higher exemption rates had higher rates of reported pertussis among exempted and vaccinated children when compared with the low-exemption counties.”

Imdad et al. on Religious exemptions for immunization and risk of pertussis in New York State, 2000-2011.

But what if the DTaP and Tdap vaccines do cause folks to be asymptomatic carriers?

Even if that is true, understand that these vaccines don’t actually infect you, making you a carrier. They just might not prevent you from becoming a carrier if you are exposed to someone else with pertussis. While that might be a good reason to develop a new and better pertussis vaccine, it certainly isn’t a reason to skip or delay your child’s vaccines now.

Remember that even with our current outbreaks, rates of pertussis were much higher in the pre-vaccine era.

What to Know About Vaccines and Asymptomatic Carriers of Pertussis

The role of asymptomatic carriers and pertussis is controversial, but it certainly isn’t a reason to skip or delay your child’s vaccines.
