that's not the feeling I have

if it was I feel like it would have stopped the spread and really reduced the number of cases

Yeah, well let's ask the "experts": https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8548286/

Basically says effective against OG, Alpha, and somewhat more limited effectiveness against Delta. It makes sense that as the virus mutates, and the vaccine was based upon earlier variants, it's harder for the body to recognize the changed/mutated strains. 

Of course, Delta was FAR more transmissible than OG or Alpha. So that made it a lot harder...

The original strain of COVID-19 had a R0 value of 2 and the Alpha, or U.K., variant had a R0 of about 2 to 3.10 The delta variant had a R0 value of 5.11 One source has the omicron variant’s R0 value as 9.12

Something can be effective individually but still not work that well at a population level. The vaccines were hitting the bulk of population coverage (in the US anyway) in the summer of 2021, which was when Delta appeared. 

And then we got to Omicron, which the vaccine is basically useless against when it comes to preventing infection/spread. 

so, it was ineffective at preventing COVID and the spread
so they switched the story and told us it was good at lessening symptoms

You might be slightly unfair

The original vac was not designed for Omicron

Folks kept taking the original vac but still got omicron

fortunately omicron saved our ass cause even though everybody could get it several times over it was much weaker

so, by the time the vaccine came out, the virus had evolved enough that the vaccine was inefficient at prevention

I understand that wasn't the vaccine's fault.
I understand it may have been effective at lessening symptoms.

That's just not the messaging we got.  until later after most folks had taken two shots

You're missing points of the timeline. 

• The vaccine came out at the very end of 2020 / start of 2021
• Rollout was slow, starting with healthcare providers / at-risk groups
• Rollout ramped up in the spring and by about the end of summer 2021, coverage was pretty high
• Delta hit the US in summer 2021, not "at the same time" the vaccine came out, but about half a year later and after most people already had gotten their two shots

I recall summer 2021, after my wife and I both had our vaccines and the world was starting to reopen and we took our first air travel since the start of the pandemic, going to Seattle in July 2021. It was a few weeks after we got back, IIRC, that Delta started spiking hard. 

I recall folks being pretty upfront that the immunity was dropping and the new variants were resistant.  There was a lot of nonmedically accurate crap being foisted by TV personalities back when.  Still is.
