By the way, just a reminder that there's still considerable doubt about how long Covid antibodies will provide immunity. Some studies have shown they drop rapidly from their initial levels. Just more reasons why I'm doubtful they're going to know anytime soon as to how effective any vaccines are.
I'm thinking the more we learn, the vaccine seems like a long shot, unless we just completely ignore how we normally do approvals. You're talking about a virus where 40% of the people infected don't have any symptoms, something like 90% have flu like symptoms and don't require hospitalization, and something like .3% of infected die from. That would have to be an incredibly safe vaccine with more or less non-existent side effects. Maybe you could just give it to the vulnerable, but a lot of the vulnerable tend to not respond as well to vaccines.

If we find out that we get the infection a second time and it tends to be worse, then that would help. But I assume that would mean developing an effective vaccine will be even harder.
