And at the time, that was true because we were dealing with the original strain.
Nothing else you said is untrue either. The vaccine drastically reduced the spread of the virus. I'm not sure what you're getting at besides spreading more disinformation.
edit: i've replied several times below but everyone needs to keep in mind WHEN things were said. When the CDC said you wouldn't catch the virus in early 2021 - they were basically fully accurate because we were dealing with the original strain. Delta did not exist yet. The original vaccines were INCREDIBLY effective against the original strain - beyond anyone's wildest expectations. 100% effectiveness against death and severe hospitalization. 95% effectiveness against symptoms entirely. These levels of protection were amazing. Yes, things changed when Delta arrived, and even moreso with omicron and future subvariants, but you can't go back with hindsight and discredit what was said _at the time_.
