LOL, do you promise you're leaving this time? Seem kind of upset. I thought just trolls launched ad homs. I guess not, huh?
Your statement, and this study, are SPECIFIC to people who were infected with Delta between May and November in California and New York. That's it. There is no need for me to disprove your statement, because it is not PROVEN by this study.

Yes, what you do IS my business, because you are prolonging the pandemic by spreading false information. In other words, by lying. That's what liars do.
Do these conflict with the CDC study? No. They are simply far less targeted or they target a different time frame. You lose. Again.
