I care about the effectiveness and approval of Pfizer's treatment, but I don't care to be informed about every single new piece of information that comes out about it. In this case the news was that Pfizer released additional data that's consistent with the interim report it released a little over a month ago. If the final analysis contradicted its original report, or if their emergency use authorization were approved or denied, that's something I'd want to see. It's still the most newsworthy item on the list IMO, and I wouldn't be upset if it slipped into my feed.
It's not news. You can read the trials yourself from months (year?) ago and know this. Important, yes, but not news.
It's buried in a mountain of spam. You might just miss it.
