There's a world of difference between "not 100% effective" and "somewhat effective". Their implications are almost the exact opposite And because she is in charge of the CDC which is spreading this false info OP said only unintelligent people are saying and is also the one to create the vaccine schedule it makes sense to link the two.
So we both agree the CDC is unintelligent
The CDC has has similar text us since before Omicron, and COVID seems to be evolving to evade vaccines faster than the vaccines themselves evolve. The BA.1 bivalent never made it to market and the BA.4/BA.5 bivalent that just hit the market is gonna get blindsided by the scrabble variants that will be dominant in the US sometime this winter.
Your point about the CDC is a fair one, but if that was the Tweeters’ point than he should have said it or he’s as guilty as the CDC as painting with a broad brush and not adjusting the rhetoric/perspective from 12+ months ago.
