The concern is they have had a recent surge in cases despite having a high % of the population being vaccinated (close to 80%). And 85-90% of those with severe cases requiring hospitalization were vaccinated individuals.
This is what you get when the efficacy studies done on these vaccines only look at the first 2 months. And we now have very good data showing the reliability and strength of natural immunity built against Covid.
I have even heard (though admittedly I haven't read up on it much as I just heard about this) that there is a worry that vaccination of those who have obtained natural immunity could actually reduce that individuals protection. I have to see and read more on that.
There were people almost a year ago now saying we could not vaccinate our way out of this and that mass vaccinations could have severe unintended consequences. But it has all fallen on deaf ears.
It is worth noting from the FL DOH the most recent numbers show that the Case Fatality Rate (which is always higher than the Infectious Fatality Rate which would be the actual fatality rate) is incredibly low for individuals under the age of 50.
40-49: 0.3% CFR
30-39: 0.1% CFR
16-29: 0.0% CFR
15-under: 0.0% CFR
These are population groups that especially if they are healthy, they really don't need to get vaccinated.
