No this was 2 family members, and both were symptomatic again. Both had high antibody titers after initial infection.

No second infection is likely dead virus being expelled from the lungs. Some symptoms are from the immune response which is still active.

Negative.. these were genotyped. These are new infections and transmission has been traced.

so was there any evidence of partial immunity from prior infection with the first strain?

Because if there wasn’t, I’d think that would bode poorly for EVER getting an effective vaccine.

True enough.

Also ironic that the same people that dismiss the concept of herd immunity are the same people saying our only chance of salvation is a vaccine. Um, vaccination is medically induced herd immunity....

Is it though? Herd immunity would take years to get to and kill millions along the way. A vaccine won't.

It's ironic you think that's ironic.

You underestimate the power of exponential growth.

Then these are the first two because every time this has come up before it has been dead virus. I would have thought this would have made bigger news.

In that vein of thought, why not just stop messing around waiting for nature and start injecting people with live viruses? Sure millions may die, but hey, it'll get the economy back on track!

I'm pointing out a mathematical principle, you think I'm advocating a position, I didn't, but you want to project the most extreme position you can think of. This thought process is why we are so divided.
