Can't see GP's comment (flagged, like 7/11 OP ITT) so I don't know if I'm on-topic or not. After Bourla's appearance on Lex's podcast and the latter's mention of a 100% claim on the blue bird app which the former denied (w.r.t. infection I believe), searching his account I came up with these. They're from March 31st (1) and April 1st (2 & 3, quoting 4), third would be most eye-brow lifting today. It is arguably misleading, or odd, to just mention 100% in a tweet on 95% CI with 53.5-100.0 brackets in the study.
1: 100% efficacy against COVID-19 disease for 12-15 year olds in phase 3
2: 100% efficacy against severe COVID-19 as defined by CDC
3: 100% efficacy in preventing COVID-19 cases in South Africa
