“No, I can’t provide a link, it’s just my own pessimistic prediction,“
However, you could look at the past history of pandemics and observe the fact that they eventually disappear as the virus that caused them mutates until it eventually ceases to be a public health treat and/or disappears.
But of course that would not fit your predilection to ‘pessimistic prediction’ and certainly undermines your ‘endless booster’ doom
mongering.
