    1. John Burn-Murdoch. (2021, August 23). NEW: in the last couple of weeks there have a lot of new studies out assessing vaccine efficacy, many of which have touched on the question of waning immunity.

    1. Carl T. Bergstrom. (2021, January 31). A somewhat technical thread about measuring vaccine efficacy.
