Seeing arguments that claim there is a trade-off between giving people 1st/2nd doses and giving people a booster shot.

That is EXTREMELY dubious in the US where we are awash in vaccines and have already ordered enough additional vax to cover boosters + kids <12 + some left over.
Is there a trade off with vaccines for other counties? I don't know, but as a matter of theory, basic economics would suggest that increased demand will increase supply. And as a matter of practice, elected officials are going to look to protect their own citizens first.
A related bad argument I'm seeing lately is that e.g. "the US is "becoming too reliant on one tool, vaccines".

Well, that's because vaccines are BY FAR the best tool. They go MUCH FURTHER than others toward allowing us to resume normal life while GREATLY reducing COVID harms.
One could very reasonably argue that vaccines pass a cost-benefit test while other interventions don't.

(Personally I'm moderately in favor of mask mandates too under some circumstances in the short run, but not in the long run.)

The sample size is this non peer reviewed study is 79 vaccinated people (corrected, misread as 83 before) and completely lacks the statistical power to differentiate between vaccinated and unvaccinanted people.
Also as in the Provincetown study it's a convenience sample, meaning people who chose to be tested, and not a random sample of all infections. That likely biases the sample toward more severe infections since people with more severe symptoms are more likely to seek out testing.
Another big statistical issue in these studies (at least the Wisconsin one) is that they have truncated samples. People with high Ct values (higher Ct = harder to find virus) are eliminated from the comparison because it's not clear they can be considered "infected".

The news is *not* that "vaccinated people easily spread the Delta variant". That reflects a gross misunderstanding of the CDC's evidence, abetted by imprecise and innumerate media coverage. See this thread below.

Vaccinated people are much less likely to become infected with COVID. *Conditional upon becoming infected*, there is some evidence to suggest they carry similar viral loads, but this evidence is quite uncertain, and viral loads do not necessarily equate 1:1 to transmission.
Of course it doesn't help when The New York Times takes some new (not yet public or peer-reviewed FWIW) study that says what I wrote above and frames it as some "harrowing new twist that upends everything we know about the coronavirus" or whatever.

There were ~240,000 reported Delta cases in the US last week (and probably another ~2 million unreported Delta infections) but yeah let's keep those Delta-carrying Europeans out!
People from Slovenia are currently banned from entering the US whereas people from Malaysia are allowed, even though Malaysia currently has >10x as many cases per capita.
You could argue that it would be too much work for the US to constantly update the list of countries based on current conditions except the State Department already does *exactly that* for Americans traveling *to* those countries.…

I think you'll see some places reimpose mask mandates and I think you'll see some fierce debates about school reopenings, but I'd be somewhat surprised if you see many COVID-related restrictions return in the US beyond that. (No idea about other countries.)
For one thing, it's not clear who the constituency for these restrictions would be. Vaccinated people are pretty safe and don't necessarily *need* them while unvaccinated people largely won't *want* them and may not abide by them.
For another, we're dealing with far different circumstances than earlier phases of the pandemic & I don't expect nearly as much consensus among public health experts on the desirability of restrictions. Even "Zero COVID" folks are now somewhat resigned.… Image

This article is confusing. Experts make a great case that J&J recipients should get a booster.

But then it's said a new study—so far described only in a J&J press release!—addressed "some of those concerns". Weak basis for concluding no booster needed.… ImageImage
Another example of the logic I find confusing.

Sure, one-shot J&J may provide decent protection against Delta and better-than-decent against severe illness from Delta. But why wouldn't you want the VERY good protection you might get from an mRNA booster?… Image
One consistent lesson from COVID is you should trust the experts' evidence (e.g. studies that show mRNA boosters really boost protection in people who got the AZ vaccine) more than their proscriptive advice (e.g. "I wouldn't get a booster) when the two are in conflict.

Kinda seems like Yang's endorsement of Garcia as his #2 mattered here. She gains a lot of ground and overtakes Wiley when Yang is eliminated.

Note that these results are preliminary; does not include absentee ballots. ImageImage
This is another key observation. About 25% of ballots were exhausted. Always fill out all your choices when participating in a ranked-choice election.
Another question: Given that Garcia barely edged out Wiley in the penultimate round before nearly catching Adams, does that mean Wiley has a path *too* once absentees are added?

My guess is Wiley has a path, but it's pretty unlikely one (see next tweet).
