Chris is expanding this article into a book, due out in May 2006. Follow his continuing coverage of the subject on The Long Tail blog. In 1988, a British mountain climber named Joe Simpson wrote a book called Touching the Void, a harrowing account of near death in the Peruvian Andes.
"La longue traîne [...] est une théorie qui décrit cette structure particulière du marché à l'ère d'internet, dans un grand nombre de secteurs. Le modèle économique ne repose plus sur une offre limitée d'articles produits à grande échelle, mais sur une offre très variée d'articles produits à peu d'exemplaires."
With this, we now know the exact mRNA contents of the BNT162b2 vaccine, and for most parts we understand why they are there:
The CAP to make sure the RNA looks like regular mRNA
A known successful and optimized 5' untranslated region (UTR)
A codon optimized signal peptide to send the Spike protein to the right place (copied 100% from the original virus)
A codon optimized version of the original spike, with two 'Proline' substitutions to make sure the protein appears in the right form
A known successful and optimized 3' untranslated region
A slightly mysterious poly-A tail with an unexplained 'linker' in there
The codon optimization adds a lot of G and C to the mRNA. Meanwhile, using Ψ (1-methyl-3'-pseudouridylyl) instead of U helps evade our immune system, so the mRNA stays around long enough so we can actually help train the immune system.
