Thank you again for the great podcast. Just a note: it looks like link in the notes titled “Effect of spike changes on protection of mice (mBio)” is linked to the wrong paper.
Thank you again for all you folks do.
As I recall Jason said in TWiV714 that in although the RNA vaccines did leave the S1/S2 furin cleavage in place they made some addition changes close to it in addition to the prolines around S2′.
