Prof. Jeong's mRNA Vaccine Design, First Steps I

Designing a vaccine
for a disease nobody has had

BtHKU5-CoV-2, reported from bats in March 2025, uses human ACE2 โ€” the same receptor SARS-CoV-2 used. Not one human case has been reported.
This paper designed a vaccine candidate for it without a single experiment and submitted five months later. This volume follows the first half of that pipeline: choosing a target and screening down to twenty epitopes.
We do not only follow. We recount the paper's own tables and find several facts the paper's text does not state.
Python runs right inside this page. There is nothing to install.

How you'll learn

๐Ÿฆ‡Start with why it was urgent

A bat virus that uses human ACE2. Human cases so far: zero.

โ›๏ธRun the funnel yourself

Seven tools, six thresholds. Move a threshold and the vaccine changes.

๐Ÿ“Recount the tables

That twenty epitopes sit in eleven loci is not in the paper. We count it.

๐ŸงพWrite down what was not done

Every number here is a prediction. Lesson 20 draws the line.
