If surviving Covid-19 doesn't confer immunity what does that say about the possibility of a vaccine doing so?https://twitter.com/VirusesImmunity/status/1299342270177726464 …
It says little. Antibody presence and efficacy are not the same. The antibodies may be enough to make a second infection much milder. Rarely it can make a second infection worse. So far the second infection is much milder. So a vaccine isn't out of the question.

If the desired outcome is reduction of severe disease and not no disease at all, this is also good and could mean more efficient use in only high risk groups. None of this can be rushed though.

Did you read the thread Jon? In this case the second infection doesn't seem to have been milder than the first.

It is a worse infection thats worrying. That would make rushing a vaccine very dangerous. Antibody directed enhancement is real.
