In fact, there isn't enough data to even know how long immunity is. And let's not get started with T cell immunity, which seems to play a role with this virus and is not touched by such a study.
Yet this doesn't mean anything as they didn't study T-cell response, and many other things.
It is absolutely ridiculous fearmongering, and clickbait, by a top university + the press.
As far as I know there has been 1 reinfection case in the entire US, and that was questionable as the guy tested positive the second time a few days after testing negative, so its possible it was a false positive. 1 case, in the ENTIRE US. It is ridiculous to suggest there isn't some sort of immunity. The virus has been around for 9 months now.
Rather on par with the coverage so far as far as I can tell. The media has been going on about "cases" (i.e. positive) tests and comparing absolute numbers between countries which do not have the same absolute numbers of people.
Wait until a new paper mentioning Quantum Teleportation is published to see how bad things can really get.
Then you'd catalogue symptoms shown by those people held in quarantine, with different innoculum doses given including placebo.
Somewhat similar to a phase 3 trial of a vaccine too, you can do it at the same time.
That's not actually true. You can get a database of people who've had it and follow up on them to see how they get on in terms of reinfection etc.
I'm kind of curious in my own case - I had it in Apr, had a positive antibody test in Jul - if I'm getting further exposure and antibody top ups. Probably I am as a public transport user in London but there's a limited access to test labs and the like.

The mood over there has been cautiously upbeat for a while now, at least in comparison to the tone often set by the mainstream media.

Also antibody-based immunity should not fade that quick (less than a month for the elderly that died) so those are fringe cases and nothing else, and trying to make some sort of rule for reinfection less than a year before the patient 0 was even infected for the first time is a bad idea.
Wait, really? A recent article in the Dutch news [1] mentioned the first death by reinfection, and also mentioned that there were at the time 23 other reinfections were known worldwide. Seems odd that there'd be just a single American in there, given the number of infections in the US.

Bad news sells unfortunately.
Scientist: "My findings are meaningless if taken out of context." Media: Scientist claims "Findings are meaningless."
I think it is clear that there is some connection though; not straightforward, but there is a link. On the other hand (as the scientist on the radio mentioned) apparently vaccines often work differently and it may be that they offer longer immunity.
Still, it's perfectly normal for antibodies to wane after an infection. I'm unsure in general what to make of this study, maybe the number just drops under the limited sensitivity of their test. This study [1] finds that antibodies are stably produced for months after the infection
