Letter to the editor: Remember the red bus?

Happy that I have finally published this work at @epljournal.bsky.social which calculates the distribution of pandemic extinction times using only NPIs (yes lockdowns) & predicts that the covid pandemic could have been eliminated in a time of order months! iopscience.iop.org/article/10.1...
