This is nonsense as there were breakthrough cases during the Phase 3 trials as the reported Phase 3 results had an efficacy of 95%. Go read the Phase 3 trial reports from Pfizer/BioNTech and Moderna. The CDC was monitoring breakthrough cases from Jan 1, 2021 to April 31, 2021, before the Delta variant caught hold.

Yes, I guess I was looking more at international data. CDC tends to mostly look at US cases. And I think the term ‘breakthrough’ was used after the Delta variant became significant.
