Sorry, if there’s no long lived immunity, there also can’t be a vaccine.

  They are hoping the immunity lasts 12 months. Then you would take a booster in your annual flu shot. I could live with that.

  That is not necessarily true. It's possible for a vaccine to elicit a stronger or longer lasting immune response than the pathogen itself. For example by adding adjuvants https://en.m.wikipedia.org/wiki/Immunologic_adjuvant https://en.m.wikipedia.org/wiki/Immunologic_adjuvant

    I don't see where in that article it says what you are describing. Only that adjuvants may improve the response to a vaccine. The response to the pathogen is not considered.

  That doesn't sound right. Perhaps there could be a stream of vaccines rather than a one-off. Also, if you can get enough people vaccinated at one time to provide herd immunity, perhaps it wouldn't be necessary to have long-term immunity, as the pandemic could be ended there and then.
