MSG in vaccines are not dangerous – debunking more anti-vax nonsense

vaccines MSG

There are so many random claims from the anti-vaccine activists about evil chemicals in your child’s vaccines – now, MSG in vaccines. Of course, MSG isn’t the only evil chemical that causes anti-vaxxers to scream loudly.

Aluminum in vaccines is dangerous? Actually, no. Mercury in vaccines? No again. Formaldehyde in vaccines is killing our kids? Nope. Of course, MSG in vaccines is causing something. Anything.

Of course, many of you have heard about MSG in our food. It’s up there on the evil food chemical list along with aspartame, high fructose corn syrup, GMO‘s, and whatever else is the food danger of the day. But MSG certainly has been on the top of the “avoid” list for decades.

I’ve been refuting nonsense about chemicals for at least 25 years on the internet (back before we had social media, yeah I’m an old dinosaur). From my perspective, I think that 50% of the issues with “chemicals” are their long complex names. And the other 50% is because of the appeal to nature logical fallacy, which is the argument that natural substances are somehow superior to “chemicals.” 

Ironically, everything in nature is a chemical, and unless you think everything in the universe is designed for human health (ridiculous), a “natural” chemical is not even close to being superior to a “man-made” chemical. 

But let’s get back to MSG – how many times have you seen “No MSG” in a sign Chinese restaurant? So if we don’t want to put MSG in our kung pao chicken, then why would we want MSG in vaccines? 

What we’re going to show in this article is that MSG dangers are a myth. And the dangers of MSG in vaccines are a bigger myth.

The facts about vaccine chemicals – debunking more pseudoscience

If you spend any amount of time on the internet researching science and pseudoscience, you’ll find alarming claims about toxic vaccine chemicals – you know, aluminum, mercury, formaldehyde, and whatever unpronounceable molecule are all the rage for the anti-vaccine crowd. Of course, we obsess over substances not only in our vaccines, but also in our foods, air, water, and coffee. Many of us try to present scientific evidence about those toxic vaccine chemicals. It can be frustrating and time-consuming.

Generally, the pseudoscience argument proceeds along the lines of “these unpronounceable chemicals are going to cause cancer.” Followed by a new trope or meme that something in vaccines does something, often without a picogram of evidence. 

But what the vaccine deniers are pushing about vaccines is based on a lack of knowledge about how toxicology – the study of the adverse effects of chemicals on living organisms, determines what is or isn’t toxic.

Paracelsus, a 16th-century Swiss-German physician, alchemist, astrologer, is traditionally thought to have founded the discipline of toxicology, an important branch of medicine, physiology, and pharmacology. Paracelsus wrote one of the most important principles of toxicology:

All things are poisons, for there is nothing without poisonous qualities. It is only the dose which makes a thing poison.

In other words, if you’re speaking about substances in foods or vaccines or anything, the most important principle is that the dose makes the poison (or toxin). Everything that we consume or breathe is potentially toxic but most important, the overriding principle must be the dose.

So, I’m going to do a disservice to the whole field of toxicology, which takes a lifetime of research and study, and I will attempt to digest it down to a few paragraphs, especially as it relates to those vaccine chemicals.
