we were on a path to that until Omicron.
The problem we face is too many people have this attitude of "well nothing works 100% so why bother trying anything". Circumstances change and instead of understanding that they just say "Well they don't know what they are talking about... one minute they say this, another they say that" People had this belief that the doctors and scientists knew everything there was to know about the virus, including future variants, in February 2020 and all of this changing is due to them being bumbling idiots.
That said, the CDC has done a horrible job at messaging. Not everyone reads twitter all day for information from people who research this stuff.
