Hepatitis B virus causes cancer – yes, the vaccine can prevent it

hepatitis b virus

A recent study provides more evidence that the hepatitis B virus (HBV) is linked to a variety of cancers – that’s not surprising to most of us. We also know that the HBV vaccine can prevent the infection, thereby preventing a wide range of cancers. 

Despite the facts supporting the dangers of the hepatitis B virus, the anti-vaccine zealots absolutely despise the vaccine, especially since it’s usually given to newborns (with a second dose recommended at 1-2 months along with a third dose at about 12-18 months) to prevent HBV infections passed from the mother.

Let’s take a look at the hepatitis B virus and this new peer-reviewed paper that discusses the link between HBV and a number of cancers. Continue reading “Hepatitis B virus causes cancer – yes, the vaccine can prevent it”

Chinese vaccine scandal – not a concern for USA and many other countries

Chinese vaccine scandal

Recently, a Chinese vaccine scandal has been reported in many news sources. According to these reports, a Chinese vaccine manufacturer produced and marketed “low-quality” vaccines for infants. Moreover, they falsified production and inspection data on a rabies vaccine – as I’ve written before, rabies is a deadly disease, with almost 100% mortality after symptoms appear,  and the vaccine is the only choice to save lives.

This is an appalling story on so many levels. Authorities in the country had lax enforcement and regulation of their vaccine industry – the government was attacked on social media about the situation, a rarity in a communist country where free speech is strictly limited. As a result, the Chinese government will begin regulating their vaccine manufacturers more closely, although it may be too little and too late.

On the other hand, Hong Kong utilizes mostly “Western” manufactured vaccines, which has led to many Chinese citizens going to that autonomous region to get their children vaccinated. There are websites devoted to showing how parents can avoid Chinese vaccines and get the “good stuff.”

These kinds of outrageous ethical lapses generally do not happen in the USA, Europe, Japan, Canada, Australia, and many other countries. Falsifying data can lead to severe criminal prosecution and civil penalties, something that is far beyond the response from Chinese authorities to this scandal.

Of course, this has led to one of the most ridiculous myths of the anti-vaccine world – our vaccines are dangerous because they were manufactured in China. Under most circumstances, this would be a laughable myth, but with this Chinese vaccine scandal, it’s important that we know where our vaccines are manufactured – spoiler alert, they are made in the USA, Europe, Canada, and Japan, all of which have strict regulation of the pharmaceutical industry.

Vaccines made in China – another ridiculous anti-vax myth

Vaccines made in China

One of the most ridiculous myths of the anti-vaccine world is that vaccines made in China dominate the US market. I took a look at every vaccine licensed for use in America to determine where they are manufactured. Spoiler alert – none are made in China.

I didn’t even know this was an anti-vaccine myth until recently. But once I looked into the topic, it was clearly prevalent in the anti-vaccine world. Many vaccines are manufactured in the USA, but the remainder are made in Canada, Japan and Europe.

Here’s a list of the most important vaccines licensed in the United States with their location of manufacture. Continue reading “Vaccines made in China – another ridiculous anti-vax myth”

Medical exemption abuse – hurting California’s vaccine uptake

Medical exemption abuse

Since the enactment of California’s SB277, which prevents parents from using religious or personal beliefs to excuse their children from vaccinations, has lead to much higher vaccine uptake rates in California schools. The law still allows medical exemptions, which are medically-related reasons for not vaccinating, such as allergies to ingredients in the vaccine. Unfortunately, this had led to medical exemption abuse in many schools in California.

In California, medical exemptions require a form signed by their doctor stating a valid medical reason for any child to not receive vaccines. Generally, less than 2-3% of children would have medical reasons to not be vaccinated. Moreover, most of these children would only be exempt from a few vaccines, not all of them.

Traditional Chinese medicine kills dolphins

Traditional Chinese Medicine kills dolphins

I am not a fan of Traditional Chinese medicine (TCM). Very few of its medical claims ever amount to anything. Most of it isn’t very traditional and doesn’t work, like acupuncture. Worse yet, TCM is involved in the destruction of rare animals like the African rhino and other endangered animals. Now, we find that Traditional Chinese Medicine kills dolphins – just to push a “medicine” that has no evidence supporting its use.

Let’s look at this recent story where purveyors of TCM have indirectly lead to the collapse and near extinction of a beautiful ocean going mammal. Per usual with TCM, it’s a tale of greed and junk medicine.  Continue reading “Traditional Chinese medicine kills dolphins”

Water fluoridation myths – just another blog article

When I was a kid (probably 6 or 7), there was a big controversy in our community whether the water would be fluoridated or not. Now, I was just becoming fascinated by science, medicine, health, and sports at that time, so I tried to figure out what was happening.

To my ears and adolescent brain, the argument boiled down to no fluoridation (which meant cavities and visits to the dentist) vs. fluoridation (which was a communist conspiracy). Scary choices. Though Nazi dentists were also plenty scary.

But I grew up, and fluoridation became more common, as communities accepted the evidence that fluoridate water was safe, and improved the health of the community’s teeth. Water systems are mostly fluoridated (unless you drink bottled water).

And fluoride is in toothpaste and various mouthwashes. I thought the fluoridation controversy had passed into history with rotary phones, the Soviet Union, and the slide rule. My younger readers probably have never seen any of those three in their native states.

Now it’s time to look at those water fluoridation myths that can be found in many corners of the internet. Continue reading “Water fluoridation myths – just another blog article”

Water fluoridation-an update

fluoride smile

This is an update of an article from 30 January 2013 to include recent studies about the efficacy of fluoridation. 

Water fluoridation is a controversy that just doesn’t seem to go away, despite the overwhelming evidence of successfully reducing the rate of cavities in children (and adults), while also having little or weak evidence that there are any risks. When I was a kid, I remember controversies about fluoridating water. But I just hated dentists, so to my young, immature scientific mind, if fluoridation kept me from the dentist, that was a good thing!

Today, fluoridated water has become ubiquitous in the USA and many other countries. Unless you drink bottled or filtered water, or avoid fluoride toothpastes (or mouthwashes), most children and adults get an adequate level of fluoride to maintain good dental health. I actually thought that the fluoridation controversy had passed into history with rotary phones, the Soviet Union, and the slide rule. 

Yes, there are groups that still fight against water fluoridation, and there are many people who think that fluoridation is bad.

The John Birch Society, a right wing conspiracy group that I thought had passed into history, still considers water fluoridation to be mass medicine and once thought of it as a communist plot to poison Americans (see Schneider & Lilienfeld, 2011). Ironically, on the opposed side of the political spectrum, leftists, like the UK’s Green Party, are opposed to fluoridation because of the mass medicine idea, a concern occasionally expressed by antivaccine proponents. So it’s really not a right or left political issue. It seems to be, like many medical issues (for example, vaccinations), a matter of good science versus bad science (or even no science).
