There's no evidence of that. The evidence says that the Delta variant's significant changes to the S, N, and M proteins make antibodies created to fight previous versions of SARS-CoV-2 less effective. That's why more COVID-19 reinfections are being observed. There is no evidence that people who got vaccinated 6 months ago have any less effective immunity against the wild type virus or the April 2020 variant.
I made a slide to show why covid vax “95% effective” was deceitful. They only started counting cases beginning at 2w after dose2. This is when Ab titers were highest, so diff was greatest between them & placebo. They stopped counting cases at 2m after dose2, before Ab dropped. pic.twitter.com/AoON2wPn3R— AMM, MD (@AMcA32449832) August 11, 2021
