Virtually all messaging I've seen has been "We lack evidence to say how immunity works" with a dose of "there's some initial evidence suggesting immunity" and "we aren't sure about how long it lasts". It's interesting to read "it's extremely infectious" and "more lethal than influenza" followed by "that's all", not to mention the missing bit about not having a vaccine! If we saw a massive outbreak of influenza things would be extremely different. We have treatments for influenza (tamiflu), we have vaccines, we have understanding, and a large portion of the population that is already immune. The similarities are... they are both viruses. Not sure why anyone would compare the two except to try to explain how different they are.
