30mcg 是疫苗总有效剂量。200kda 是突出蛋白的size .
.Dalton (Da) is an alternate name for the atomic mass unit, and kilodalton (kDa) is 1,000 daltons. Thus a protein with a mass of 64kDa has a molecular weight of 64,000 grams per mole
疫苗除了mRNA 还有载体的等其他成分。
另外: Approximately 360,000 mRNA molecules are present in a single mammalian cell, made up of approximately 12,000 different transcripts with a typical length of around 2 kb.
37.2 trillion cells. This is not a final number, but it's a very good start. While it's true that people may vary in size–and thus vary in their number of cells–adult humans don't vary by orders of magnitude except in the movies
