What’s in Merck and Moderna’s cancer vaccine algorithm?

Moderna is raising $2 billion in convertible debt following the success of its personalized cancer vaccine developed with Merck. The vaccine uses an algorithm to analyze tumor mutations and create a bespoke mRNA treatment. Some investors question the necessity of personalization. Meanwhile, a U.S. biotech crackdown on China could benefit European companies, and a rival drug failure may impact Alnylam's ATTR-CM franchise.
