Where are the citations for any of this?

Where are the citations for any of this? I have been following delta closely and have heard basically none of this. Almost none of your claims about the size and scope of this new wave are cited. This is a terrifying moment to be sure, but the hospitalization and death rates are far lower this time because of the vaccines. Spreading uncited alarmism that implies vaccines arent effective in protecting people against this variant is beyond irresponsible.
