I'd like to start giving people the option of commenting on shorter Cold Takes pieces (which I don't cross-post here or provide audio for). I'm going to use this post for that: I will generally leave a comment for each piece, and people can leave their comments as replies to that.
Thanks for this post- I forwarded it to a Oxford bioethicist and nudged him to write about it and they just published a thoughtful piece on it in the BMJ: 'Regulating strain-specific vaccines – speed, rigour and challenge trials'.
