The focus is on Cape Cod because it was used by the CDC to determine that there a a large risk of fully vaccinated people spreading the Delta variant to other fully vaccinated people. The spread in FL (at least based on information from Orange County) is over 96% being spread to unvaccinated people.
Conditions like whatever activities were going on at the Cape Cod gathering might be necessary for Delta to spread so efficiently between fully vaccinated people. As I said in an earlier post, they also need to investigate things like were these people taking medications that they had in common or illegal substances which may have reduced vaccine efficacy.
The CDC said that they changed guidance to "fully vaccinated should wear masks indoors" based on a study in India where people are vaccinated by a different vaccine and the Cape Cod cluster. I think it's time to focus more on Cape Cod, not less.
There are so many variables, it's really difficult to pinpoint, short of complete isolation and complete reporting of a population of significant size.
The best example seems to be the general description of "vaccinated". Not all are vaccinated with the same products, though the efficacy numbers for each of J&J, Pfizer and Moderna were published right at the outset with what was available information at the time. We're all being lumped into that group, though not all are equal.
Mask usage, quality of masks, hand washing ( 10 seconds. 20, 30? Soap? I've seen those who splash their hands and walk out as well as worse), distancing, someone coughing, etc. are all factors that are not being taken into account because of the complexity of gathering that data. How many of those infected by Delta now were ever infected with Alpha?
I'm vaccinated, but to date, I was never tested for Covid. I kept low, still not sick
at all with anything since before the beginning of 2019, yet I may have caught it and gotten through it with absolutely no effects other than unknowingly passing it to someone in the supermarket pre-March of 2019.
Focusing on Cape Cod is not bad per say, it's just on the more convenient side.
People like simple answers to what is not a simple problem.
I bet some of you have had a contractor in mind to do something and you ask how much something will be.
"It depends."
