This week an elderly UK woman became the first person outside of a trial to get the newly approved vaccine developed by Pfizer and BioNTech, and the US could greenlight the same inoculation as soon as Thursday, December Reading the ingredient list is like looking at the side of a cereal box, except that you need a degree in organic chemistry to understand it.

We got help from various scientists and biotech entrepreneurs to understand what each of the ingredients does and make some educated guesses about others. Imagine an mRNA as a long ticker tape carrying instructions. On its own, without the rest of the virus, the spike is pretty harmless. But your body still reacts to it.

This is what leaves you immunized and ready to repel the real virus if it turns up. But Pfizer is holding back a little. The spike gene sequence can be tweaked in small ways for better performance, by means that include swapping letters. The nanoparticles are, basically, tiny greasy spheres that protect the mRNA and help it slide inside cells.

These particles are probably around nanometers across. It's also a component that can cause side-effects or allergic reactions. The Pfizer vaccine contains four salts, one of which is ordinary table salt. Substances with the wrong acidity can injure cells or get quickly degraded. The vaccine includes plain old sugar, also called sucrose.

Before injection, the vaccine is mixed with water containing sodium chloride, or ordinary salt, just as many intravenously delivered drugs are. Again, the idea is that the injection should more or less match the salt content of the blood. The US Centers for Disease Control says thimerosal is safe; despite that, its use is being phased out. There is no thimerosal—or any other preservative—in the Pfizer vaccine. No microchips, either. Salts The Pfizer vaccine contains four salts, one of which is ordinary table salt.
