Is anyone aware of research on the susceptibility to the Delta variant of people who had a natural infection of #COVID19 (seropositive) and then got fully vaccinated with an mRNA vaccine on top of that?

Asking for a friend.
Cc’ing @florian_krammer @DrTomFrieden @VirusesImmunity @apoorva_nyc who have been insightful in the past.
3/ Just went to @nyulangone to give blood for a research study I joined back in March 2020, when I was hospitalized there. I go there every few months to donate.
4/ I asked if they have had any subjects who got #COVID19, got vaccinated, and got reinfected with #COVID19; they have not. Their research shows robust immune response (but note that this isn’t about Delta specifically).
5/ Thanks for all the great responses, everyone! They fall into several categories.

First, comments that based on earlier research, prior infection plus vaccination seems to confer robust immunity that should cover Delta. E.g.,

6/ Second, comments citing studies showing that in general, the mRNA vaccines seem to be effective against the current known variants, including Delta.
7/ Third, a study showing that prior infection + vaccination seems to work well against Delta (thanks, @MaxKennerly):

8/ Fourth, some anecdotal accounts of folks who had Covid, got vaccinated, got Delta, and experienced mild illness.
9/ Fifth, a very small number of anecdotal accounts of folks who had Covid, got vaccinated, got Delta, and experienced serious illness.
10/ Bottom line: those of us who had #COVID19 and then got #vaccinated with two shots of an mRNA vaccine are unlikely to get reinfected, even with Delta, or experience serious illness in the event of reinfection with Delta.
11/ All that said, it's never a bad idea to take reasonable precautions, especially if they are not a big deal or burden.

Thanks again to everyone for the helpful information and responses!

1/ An important update regarding the hiring as a #SCOTUS clerk of Jessica (Jessie) Garland, daughter of Attorney General Merrick Garland, by Justice Kagan.

From Patricia McCabe of the Supreme Court Public Information Office:
2/ I appended this to the end of my earlier thread, but since I really can't make heads or tails of why Twitter displays some of my tweets widely and others not at all, I'm tweeting it out this way too.
3/ The key points:

(a) Justice Kagan hired Jessica Garland BEFORE #MerrickGarland was AG (and before @JoeBiden was elected president.

(b) Jessie Garland won't clerk for Justice Kagan at #SCOTUS during Merrick Garland's tenure as AG.

1/ Before my critical case of Covid-19, I had a resolution to walk or run at least 25 miles a week, which averages out to around 3.5 miles a day. And I generally adhered to it.
2/ From 2015-2019, I basically managed to keep this resolution. Here are the years and my average daily walking/running totals (per the handy Health app in my iPhone).

2015: 4.2
2016: 3.7
2017: 4.3
2018: 3.8
2019: 3.9
3/ In 2020, thanks to Covid, I averaged just 2.4 miles a day. I did hardly any walking in March, much of which I spent in the hospital, and April, the first month of my recovery (when I could barely walk across the house or up a single flight of stairs).

1/ Everyone keeps assuming that Justice Stephen Breyer will retire from #SCOTUS either this year or, as is looking more likely right now, next year.

But what is the basis for this assumption? Might Justice Breyer stick around for several more years?
2/ In his recent interview with @JoanBiskupic of @CNN, all Justice Breyer said was that (a) he hasn't decided on when to retire and (b) he would consider his health and the needs of #SCOTUS in deciding.

What do those factors say right now about retirement?
3/ Justice Breyer seems active and healthy, and he's still making meaningful contributions at #SCOTUS.

This past Term, he wrote opinions for the Court in such major cases as CA v. TX (the big ACA case), Mahanoy v. BL (student free speech), Google v. Oracle.

1/ THREAD. Today marks the seventh anniversary of the murder of law professor Dan Markel.

He touched so many lives, as reflected in these recollections from those of us who were lucky enough to know him.
2/ Seven years later, not everyone involved in this horrific crime has been brought to justice.

Here is a statement just issued by Dan's parents, Ruth and Phil Markel, through their lawyers, Orin Snyder and Matt Benjamin of @GibsonDunn.
3/ Here is a video version of the Markel family's statement, posted on the “Justice for Dan” Facebook page.

1/ THREAD. Some of the coverage connecting the departure of John Demers as head of the Justice Department’s National Security Division to the uproar over the DOJ leak investigations is a bit misleading.
2/ Look at all of these headlines, which imply that John Demers’s departure was prompted by the furor over the leak investigations, Apple/Google subpoenas, etc.
3/ But then read this @nytimes by @ktbenner, which has the right facts (even if the headline and sad-face photo, which Benner isn’t responsible for, reinforce the narrative that John Demers’s departure is tied to the scandal).

1/ THREAD. I'm conducting a poll for my newsletter/blog, Original Jurisdiction (if you're not familiar with the subject, read the rest of this thread):

Did you like Judge Kenneth Lee's opinion in Briseño v. Henderson (9th Cir.)? #appellatetwitter
2/ Here's a link to Judge Lee's opinion in Briseño v. Henderson, so you can check it out for yourself before reading the commentary:
