COVID vaccine result was a fluke

Larry, Moe and Curly would be proud.

AstraZeneca’s best COVID vaccine result was a fluke. Experts have questions

... the COVID-19 vaccine they developed together appeared up to 90 percent effective at preventing disease. But in the days since, that exciting news melted into a pool of confusion after it became clear that the 90 percent figure came about from a complete accident.

AstraZeneca and Oxford have been mum about how that error occurred exactly. Meanwhile, outside experts have raised doubt about whether the 90 percent efficacy with the half-dose/full-dose is even real, given the smaller number of participants.

They could at least tell us the effectiveness of the "full dose" trial if they remove the older participants from the count. I suspect it would zoom up from the published 62% figure. Maybe even higher than the 90% for the half-dose/full-dose!

the 90% figure. So I'll just hold off getting excited about it for right now.

And "serendipity" should be read as "we weren't looking for this, we don't even know if it's real. We should take a closer look."
