This is not in anyway true and I’m not sure why you’re suggesting it is. Dr. Deborah Birx has said expressly that we don’t know the duration of immunity and initial reviews suggest immunity might not last as long as we’d hoped: https://www.technologyreview.com/2020/04/27/1000569/how-long-are-people-immune-to-covid-19/ https://www.technologyreview.com/2020/04/27/1000569/how-long...

This article is discussing the hope that immunity lasts forever, and I agree there's no reason to believe that. The important question is whether it's shorter than a year or two - we're developing other strategies to handle the virus on timescales beyond that.

  > This article is discussing the hope that immunity lasts forever Nowhere is this stated or suggested. Why are you saying that it is? The only point it makes (contrary to all your claims) is we don’t know the duration of immunity and the situation is unpredictable, based on what we know of other coronaviruses. From the article: >What I have been telling everyone—and no one believes me, but it’s true—is we get coronaviruses every winter even though we’re seroconverted,” says Matthew Frieman, who studies the virus family at the University of Maryland. That is, even though most people have previously developed antibodies to them, they get the viruses again. “We really don’t understand whether it is a change in the virus over time or antibodies that don’t protect from infection,” he says. > After testing different scenarios, the Harvard group concluded that their projections of how many people end up getting covid-19 in the coming years depended “most crucially” on “the extent of population immunity, whether immunity wanes, and at what rate.” In other words, the critical factor in projecting the path of the outbreak is also a total unknown.
