a. you aren't mandated to get the flu shot every year
b. people aren't masked up, social distancing isn't imposed, and business aren't restricted during the flu season.
c. about only 45% of the population gets their annual flu shot.
d. people still get (and die) from the flu.
The Israeli/Gottlieb approach is based on continuing protections (though lower grade than lockdowns) until enough of the population receives the booster so some semblance of herd immunity is reached. The English version just acknowledges, as Campbell said, "everyone is going to get it" so lift the restrictions now and natural immunity will serve as a booster (now maybe modified with, boosters for the vulnerable, if they want it). If you go with the Israeli/Gottlieb, things like masks and other restrictions make sense because you are trying to minimize disease in the present). If you go with the UK, you open it up all now (and/or you force people to get their first shot and then open it up).
