I think that's a bit misleading. Essentially, he said that they didn't study that as it was not what the initial clinical trial was designed to test. Regardless, if the vaccine protects against severe disease only, that's still infinitely better than where we are now.
I did see that the DOD is rolling out "Vaccination kits with ID cards". I wouldn't be surprised for these to be required, at least for a year or two once things do start back up.

Lastly, I spoke with someone in healthcare here in Alabama who stated that the ADPH (Dept. of Public Health) has the initial numbers and locations of Pfizer vaccine ready to go (apparently, the state's 6 largest hospitals will have the cold storage capacity to store vaccine) as soon as FDA issues an EUA. They said, at least here, they would follow the CDC guidelines issued by ACIP earlier this week. Apparently, we will receive something like 40,000 doses on day 1, with supplies ramping up weekly (whatever that means). As a point of clarification, I mentioned to the person I spoke with that that would only allow 20,000 people to be vaccinated, however, they pointed out that no, 40,000 would be vaccinated that first week as they wouldn't be getting the next dosage until 21 days later. Not sure why I hadn't processed that in my head, but it makes perfect sense... Also, as an aside, they mentioned that providers are being enrolled into a vaccine distribution system now (though the public has not seen who these providers will be - I assume that will go out if and when an EUA is issued).
On a related note, they also mentioned that they were seeing very good results with the Eli Lilly Monoclonal Antibody, so don't forget about that line of treatment as well (though, apparently, this is most effective prior to one needing hospitalization...)
