Interesting opinion article. The term 'durable immunity' has not been explicitly defined anywhere in the text though and it might have been useful for readers to know what exactly is being implied by the author in this regard. Also, the statement "If immunity to SARS-CoV-2 and seasonal CoVs are similar.." doesn't sound like an apt one. I wonder why immunity to SARS-CoV-2 isn't being compared here to that of SARS-CoV especially since both of the viruses belong to the same species? Curiously, MERS-CoV fails to find a single mention in the article.
