Measles immune suppression – Tetyana Obukhanych cherry-picking

Recently, I wrote an article about measles immune suppression, a serious complication of the disease, and one of the great reasons to get the measles vaccine. According to two peer-reviewed articles, one published in the prestigious journal Science and the other article in a sister journal Science Immunology, researchers described that measles infections destroyed some immune memory cells, causing the individual to lose protection to some diseases.

Of course, the anti-vaccine zealots’ favorite false authority, Tetyana Obukhanych, decided to deny the solid scientific articles that established one of the well-known complications of measles. It’s not like anyone should take her babbling pseudoscience seriously, but just in case someone does, it’s important that we point out that Obukhanych is wrong once again.

Measles damages the immune system – more reasons for MMR vaccine

measles damages the immune system

It’s been well known for years that measles damages the immune system, one of the many dangerous complications of the disease. That’s one of the many reasons why we are so strongly in favor of the MMR vaccine and so strongly against measles outbreaks.

Of course, the anti-vaccine zealots will continue to believe that “natural” measles infections will confer some super-immunity to their children. Many deliberately try to infect their kids with the disease.

However, this scientific research, published in one of the most prestigious peer-reviewed scientific journals on this planet, provides convincing evidence that measles damages the immune system. And we should make sure our children don’t contract this dangerous disease. Continue reading “Measles damages the immune system – more reasons for MMR vaccine”

Lyme disease vaccine in clinical trials – good news for everyone

lyme disease vaccine

Even though dogs have access to a Lyme disease vaccine, there has not been a vaccine available for humans for 18 years. But that’s about to change, considering how much the tick responsible for the disease has spread.

Just to be clear, vaccine manufacturers do not value dogs more than humans for a Lyme disease vaccine. In reality, the blame for why there isn’t a Lyme disease vaccine can be placed right where some of you expect it to be – loud-mouthed, misinformed anti-vaccine zealots who lacked any scientific evidence supporting their claims.

Of course, the issues with the original Lyme disease vaccine happened in the mid-1990s, and the internet was in its infancy (hello AltaVista). But there were people pushing the same narrative that we hear about the cancer-preventing HPV vaccine – they claimed, without any scientific evidence, that the Lyme disease vaccine was actually worse than the disease itself.

That certainly sounds familiar!

But a new Lyme disease vaccine might be on its way fairly soon. That means adults and children can run in the grass, go hiking, and generally enjoy the outdoors without worrying about this debilitating disease.

Measles infections prevent heart disease – an anti-vaccine trope

measles infections prevent heart disease

Here we go again, another anti-vaccine trope based on one paper without adequate scientific criticism of the said paper. What is this trope? Mumps and measles infections prevent heart disease and stroke. Let me jump right to the conclusion – wrong.

Although I’ve seen this story before, like most zombie tropes in the anti-vaccine world, this one has come back from the dead. In the pseudoscientific website, Health Impact Newsthe author writes:

By my calculations, natural infection with the measles and mumps will prevent millions of heart attacks and strokes. Why is this information not all over the TV and internet? I will tell you why. Because mainstream media is in bed with Big Pharma who pay their bills. The politicians are slaves to their corporate masters. Our children should be exposed to every virus and bacteria for which a vaccine exists.

The author’s shrill claim is based on a 2015 article published in the lower impact factor journalAtherosclerosis. The authors concluded that “measles and mumps, especially in case of both infections, were associated with lower risks of mortality from atherosclerotic CVD (cardiovascular disease).”

Now, it’s time to turn a critical and skeptical eye towards that article. Continue reading “Measles infections prevent heart disease – an anti-vaccine trope”

SSPE – a dangerous complication from not getting the measles vaccine

One of the tropes of the anti-vaccine religion is that childhood diseases, like measles or whooping cough, are not dangerous. But real science tells us that measles complications, like SSPE (subacute sclerosing panencephalitis) and death, are not innocuous. The ignorance about measles puts our children at risk.

Sadly, some of these vaccine-denying parents have set up “pox parties” to deliberately expose their children to these diseases, because they believe that natural immunity is better than vaccine-induced immunity. Not only is that an appeal to nature fallacy, but it shows ignorance on how immunity works.  Continue reading “SSPE – a dangerous complication from not getting the measles vaccine”

Chronic Lyme disease – is there any scientific evidence supporting it?

chronic lyme disease

Chronic Lyme disease (CLD) is a generally unrecognized medical diagnosis that contains a broad number of disorders or symptoms that are supposedly related to a Lyme disease infection. There is no reproducible or convincing scientific evidence of any relationship between the symptoms and Lyme disease. There is no evidence that chronic Lyme disease is caused by a persistent Lyme disease infection. In fact, there’s little evidence that CLD “patients” ever had Lyme disease itself.

Despite this lack of scientific, medical and clinical evidence, a whole cottage industry has arisen to promote the myth of chronic Lyme disease along with selling expensive treatments that have shown little or no clinical efficacy. Furthermore, a whole activist movement that argues that CLD is a real disease, and they can be a vociferous and radical as your every day anti-vaccine activist. In fact, a lot of the arguments are similar between the CLD and anti-vaccine groups – over-reliance on anecdotes, cherry-picking scientific articles, and claims of some sort of conspiracy.

But we’re going to ignore all of that. This article will take a look at the best scientific evidence that has examined the claims about chronic Lyme disease. Because the only thing that matters is scientific evidence. Continue reading “Chronic Lyme disease – is there any scientific evidence supporting it?”

What causes autism? Maybe infections during pregnancy but not vaccines

causes autism

Despite the rigid beliefs of the anti-vaccine religion, the science is settled – vaccines are not causally linked to autism or any other neurodevelopmental issue. Arguing about this is a waste of time, if not for the fact that some parents might resist vaccinating their children because they heard these unfounded claims. But that doesn’t mean scientific research has quit looking for what causes autism.

Scientific research has focused on genetics as the underlying cause of autism spectrum disorder (ASD) (see Note 1). But often, environmental triggers could induce the upregulation of genes, which may lead to ASD.

During this search for what causes autism, scientists have uncovered a potential link between infections during pregnancy and autism. In fact, this new data may be evidence for pregnant women to be fully vaccinated before and during pregnancy to reduce the risk of those infections. Continue reading “What causes autism? Maybe infections during pregnancy but not vaccines”

Whooping cough outbreak – science and simple math

whooping cough outbreak

I have written extensively about several whooping cough (Bordetella pertussis) outbreaks which had reached epidemic levels in areas like the Washington state, which had been considered one of the worst outbreaks in the USA during the past several decades. This whooping cough outbreak has lead to several deaths here in the USA and in other countries such as the UK.

Of course, these outbreaks and epidemics have lead to the “blame game” from the antivaccination cult, because they have claimed that since A) most kids are vaccinated, and B) we’re having this outbreak, then C) either the vaccines are useless or are actually the cause of the outbreak. Seriously. They blame the vaccines.

There have been numerous reports about a whooping cough outbreak in the Reno County, KS area, with about 70 cases of the disease being reported. The report indicates that most of the kids who have the disease were vaccinated. It is unclear who said this, and what are the actual statistics. But for now, we’ll take this at face value.

Since this outbreak will undoubtedly lead to the typical antivaccine rhetoric about the whooping cough vaccines, DTaP or Tdap (which also protect against tetanus and diphtheria), I decided to search the internet to find the most popular vaccine denialist arguments regarding pertussis vaccinations–then debunk them. Hopefully, this will be useful for those who are observing what’s going on in Reno.

HPV vaccine safety – another massive scientific study (UPDATED)

HPV vaccine safety

In a 2013 study of over 1 million girls, the overall HPV vaccine safety for teenage girls was reaffirmed. There appear to be no links between serious adverse events and the HPV vaccines. This is in line with numerous other large size epidemiological studies of HPV vaccines.

Let’s take a look at the HPV vaccine safety that is supported by this trial.

Chronic Lyme disease treatments – unproven and dangerous

Chronic Lyme disease treatments

More and more people are being misdiagnosed with “chronic Lyme disease,” a medically unrecognized condition that encompasses (pdf) “a broad array of illnesses or symptom complexes for which there is no reproducible or convincing scientific evidence of any relationship to B. burgdorferi infection.” A whole industry of chronic Lyme disease treatments have arisen over the past few years to treat this pseudomedical condition.

There is no evidence that the symptoms of “chronic Lyme disease” are caused by a persistent and hidden B. burgdorferi infection. According to the eloquent Orac, it is simply a “fake disease.”

On the other hand, post-treatment Lyme disease syndrome (PTLDS) describes a set of persistent symptoms that arise after successful treatment of the Lyme disease. The symptoms of “chronic Lyme” are generic and non-specific “symptoms of life.”

Chronic Lyme disease treatments include mostly alternative medicine therapies, especially controversial and harmful long-term antibiotic therapy, particularly intravenous antibiotics. The CDC specifically disputes the effectiveness of long-term use of antibiotics to treat Lyme disease.

A new report from the CDC examined chronic Lyme disease treatments, and found that they are expensive, that they don’t work, and that they can be dangerous. Let’s take a look at that study. Continue reading “Chronic Lyme disease treatments – unproven and dangerous”
