My take—I personally think the Oxford AstraZeneza #COVID19 vaccine at 90% efficacy (with its half-then-full dose regimen) simple refrigeration vaccine that costs $2.5-4/dose is superior. Cheaper + much easier to ship https://abs.twimg.com/emoji/v2/... draggable="false" alt="➡️" title="Pfeil nach rechts" aria-label="Emoji: Pfeil nach rechts"> means save more lives worldwide.

2) For the record, we need to stop quoting the 70% efficacy number. It’s a mix of regimen 1&2, which is not possible in the real world. You only take either 1 or 2, not both. Thus it’s either 90% or 62%. Many new outlets made this error, which I myself at first read. 90% folks!

3) Eventually, I think all 3 vaccines might be in the 90% ballpark for efficacy once more data comes out. Also Oxford vaccine reported also asymptomatic infections. While Pfizer did not—only symptomatic. Because asymptomatic can also spread it, I think that is key.

4) And it’s not a little cheaper. Oxford vaccine is like 8-12x cheaper than the other Moderna and Pfizer vaccines. That price difference means millions or even billions can get the vaccine sooner and faster. Speed saves lives.
