Re: Red (# 2)

Lipids are fats or oils. Their inclusion in the formulation is as a coating to keep the mRNA stable. Even so low temperature storage is needed for stability.

As to the specific chemicals, this is complicated chemistry that cannot be easily explained to anyone without a background in chemistry. I'm a chemical engineer who studied a fair amount of chemistry but I am not an organic chemist and cannot tell you the what and why of all these components.

Lastly, I suggest you trust the vaccine scientists and not question the details of the chemistry.
