it's very good. better than expected. we still need to wait for more results to come in but it's going to be effective enough to give us a chance to eradicate this virus. while 50% efficacy would've still been useful, 90% effective helps on so many fronts. even if it ends up being 80%, it's still great. given both mrna vaccines have similar numbers, it seems to be real and not some statistical fluke.
I want to know if the dozen or so people who got the vaccine and then got infected had a more mild course as well, and/or were they less infectious.
I also want to know how long the immunity lasts. months? years?
it's incredible to think that we could have a vaccine deployed by spring or even winter. that's faster than even the more optimistic estimates from this past March.
