    1. Dowdy, D. (2021, September 21). On the J&J booster news, keep in mind: 1. Median follow-up since 2nd dose was just 36 days, 2. Efficacy vs moderate COVID was 75% globally, and 3. Total number of cases in the US was 15. Please don’t take this to mean that a 2nd dose provides long-term increase in protection.

    1. Carl T. Bergstrom. (2021, August 18). 1. There has been lots of talk about recent data from Israel that seem to suggest a decline in vaccine efficacy against severe disease due to Delta, waning protection, or both. This may have even been a motivation for Biden’s announcement that the US would be adopting boosters. [Tweet]. @CT_Bergstrom. https://twitter.com/CT_Bergstrom/status/1427767356600688646

    1. Hilda Bastian, PhD. (2021, February 6). Unofficial unnamed AstraZeneca insider says they are doing the interim analysis for the US trial of the Oxford vaccine.

    1. (((Howard Forman))). (2021, June 28). There are few more compelling graphics to demonstrate how effective vaccines are: 80+% reduction in hospital admissions for the group most vaccinated. <40% reduction in admissions for the group least likely to be vaccinated.

    1. Marc Lipsitch. (2021, July 20). At the risk of boiling down too much and certainly losing some detail, one way to summarize this wonderful thread is that when we think about vaccine effectiveness, we should think of 4 key variables: 1 which vaccine, 2 age of the person, 3 how long after vax, 4 vs what outcome.

    1. CDC. (2022, February 4). A new @CDCMMWR study shows that people who reported always wearing masks or respirators in indoor public settings in California were less likely to test positive for #COVID19 compared with those who reported not wearing a face covering.

    1. ReconfigBehSci. (2021, July 19). this is how the failure to understand what efficacy means and how it relates to outcomes will be seized on over and over again.

    1. John Burn-Murdoch. (2021, August 23).

    1. ReconfigBehSci. (2021, July 20). No it doesn’t- it reflects the statistics of what, mathematically, has to happen as more and more people are vaccinated with a vaccine of less than 100% efficacy (as all vaccines are) [Tweet]. @SciBeh. https://twitter.com/SciBeh/status/1417520720960131073

    1. Carl T. Bergstrom. (2021, May 27). An update on the B.1.617.2 lineage. I’m concerned. Not because of reduced vaccine efficacy, but simply because a further increase in transmissibility above B.1.1.7 would be quite bad news for countries where vaccination is low and for hopes of near-elimination everywhere.
