Dr. Son's mRNA Vaccine Design, First Steps III

29,620 epitopes
are not a vaccine

Part II found the epitopes. This part filters and ties them.
One cutoff โ€” percentile rank ≤ 1.6 โ€” cuts 29,620 down to 1,443; experimental evidence and three safety screens cut 1,443 down to 5. The survivors are tied with four linkers (EAAAK, GPGPG, AAY, KK) into a 309-residue construct.
You will run the internal checks yourself, such as 309 × 3 = 927. Python runs right inside this page. There is nothing to install.

How you'll learn

โฌThree numbers to remember

29,620 → 1,443 → 5. This funnel is the spine of the course; every lesson tells you where in it you are.

๐Ÿ“Each ruler measures one thing

Rank measures binding, assay counts measure record, coverage measures HLA frequency. We always name what each cannot measure.

๐ŸชขPick the knot, then tie

EAAAK, GPGPG, AAY and KK each do a different job. Choosing a linker is choosing a presentation pathway.

๐ŸšงWrite down what cannot be said

Every number in this paper is a prediction. Lessons 17, 18 and 20 draw that boundary.
