Unless they lockdown forever it's literally not going to matter. Additionally the longer they delay the acquisition of natural immunity the worse it will eventually be. The best course of action in the begining would have been to encourage only the vulnerable to isolate. Natural immunity is much better than the vaccines. COVID currently is worse for vaccinated people than it was for unvaccinated a year ago. The rate of severe infection with Delta among vaccinated is higher than the rate of severe infection of the general population a year ago with Original COVID. Natural immunity has less than 1% reinfection rate vs a nearly 40% infection rate for fully vaccinated. We talk about how all the current deaths of unvaccinated people could be prevented with vaccines, but skip that they could have also been prevented in 99% of cases by them simply catching COVID last year. Im all for vaccines and vaccine + COVID infection is currently the best protection, but that is an actually riskier proposition than simply having caught COVID in the begining for normal healthy people.
