Basic vaccine chemistry – help for science deniers

If you read almost any anti-vaccine screed, and if you have even a minimal chemistry background, you will assume that the anti-science vaccine deniers are also chemistry deniers. Therefore, I thought I would create a quick list of basic vaccine chemistry for those who have to deal with the vaccine deniers.

About a year ago, the website, The Logic of Science, published an article about five simple chemistry facts. I thought I’d take their list and apply it to an article about basic vaccine chemistry.

I know that we are oversimplifying chemistry. But I think most of us, who focus on the overwhelming evidence that vaccines are safe and effective, know that there are fundamental principles of chemistry that are the basis of biomedical science.

Without further ado, let’s look at basic vaccine chemistry.

Simple math – the dose makes the poison

If you spend any amount of time on the internet researching science and pseudoscience, you’ll find alarming claims about toxic or poisonous substances in our foods, vaccines, air, water, and so much else. And then you’ll find a lot of people (myself included) who try to present science-based evidence that these substances are neither toxic nor poisonous.

Generally, the pseudoscience argument proceeds along the lines of “this unpronounceable chemical is going to cause cancer.” And the science (read scientific skeptic) side says “wrong!” Or something like that.

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 can consume or breathe is potentially toxic, but what is the most overriding principle must be the dose.Read More »Simple math – the dose makes the poison
