With the voting window closed, we have a tie with 2 votes each for mattrom 12 and darla 33. With no other way to break the tie (likes or votes for other clues), I must pick a winner. Nothing wrong with either clue, but if I had a vote I would have cast it for mattrom's clue.
So mattrom 12 takes the gold with the reverse butt-crostic:
Getting flu jab in every bottom upended virus (3)
Congrats mattrom, tough luck darla, and thanks to all for playing.
