It does feel a little soon, since there are still big unknown in terms of variants and how effective it is for people with weakened immune systems, and how long the effective protection lasts. That said, I think what people miss is that CDC is not making recommendations for you not to catch Covid, it's making recommendations in the aggregate of what seems like acceptable risk for the pandemic. So that means some vaccinated might still get Covid, but most won't or will with minor symptoms that is not life threatening. In that regard they probably want to encourage people to go back and stimulate the economy.
