'No evidence' that recovering from Covid-19 gives people immunity, WHO says

There was no evidence of human-to-human transmission early on, too.

“No evidence” is not “evidence against immunity”. It means we don’t know yet.

I have two comments about that:

1) Like somebody else said, if you don't look, you won't find evidence, even if it's there.

2) Wuhan officials were incentivized to say it wasn't contagious, ergo, no lockdown needed.

However, it clearly was being transmitted to non-wet market patients in late Nov./early Dec., and Disneyworld Shanghai was closed Jan. 24, so you have to be wilfully blind to say it's not contagious.

Yes, the WHO is not a spy organization. They rely in large part on cooperation from member nations.

Sometimes that’s an issue, but it doesn’t mean they were lying when they said they didn’t have the evidence yet.

There's no evidence, but should we expect evidence? Has anyone looked?

The Bayesian prior that they should have some level of immunity is pretty high, seems to me. Exactly how long and how strong such immunity is a good question, but it would be really unlikely if there was no immunity.
