Claims 90% efficacy with half-dose than full-dose a month later, but only 60% if done with two full doses a month apart. No need for subzero storage, regular pharmacy refrigerators will be fine.

Could anyone explain "This is the only western vaccine in such late stage without a stabilized Spike in the pre-fusion conformation." to me?

So less is more? And they thought to do the trial that way. Would be good to understand why.

Phase 2 trials often are ‘multiple ascending dose’ since they’re trying to balance safety and efficacy, which are presumed to be a trade off, and neither of which are known with much confidence going in.
What gets me is the lighter dose being more effective. Want to know their n and that it wasn’t just noise.

I take my vaccines like I take my women.
Extra cold and double dosed.

I’m not the only one curious about this.

At this point, 538 would not be my go-to for statistical anything...

Wait, this wasn’t a ‘multiple ascending dose’ P2. It was p3 and the light dosing was an accident. Fairly low n of 3k. They’re going to have some explaining to do.
