This is from the CDC:

The rapid growth rate in Omicron infections is believed to result from a combination of increased transmissibility and the ability to evade immunity conferred by past infection or vaccination (i.e., immune evasion)
4; 5. Data from laboratory experiments and epidemiologic investigations suggest a greater role for immune evasion than increased transmissibility; immunity conferred by prior infection or vaccination is likely to be reduced compared with Delta but not completely overcome
6; 7; 8. Data also show that vaccinated people who either receive a booster dose or who were also previously infected are likely to have stronger protection against Omicron
9; 10; 11 .
Now I fully admit i've become ignorant as i've stopped paying attention because it just seems never ending, but to me this seems like the vaccines are not nearly as good against Omicron as it was the previous variants. We have updated with Booster shots, but from what I know booster shots are just another of the same right?
My point tothis is i'm wondering why new vaccine variants haven't been developed, or a new vaccine to have a better rate of protection against Omicron and future variants? Don't we update our flu shots every season to accommodate the new flu variant?
On the side, I also want to point out that my browser, this post section, is telling me the words transmissibility & epidemiologic were mispelled by the CDC. I just cant trust anything anymore! Either the CDC cant spell or my spellchecker is a liar.
That's why I don't put more effort into fixing typos. I'm not writing a paper for Oxford in here, lol.
