The problem with herd immunity is that for this particular virus, there is no science to back up this strategy. Plenty of experts are saying that herd immunity comes from vaccines, not from an active pandemic. Herd immunity was essentially the only recourse during times of plague etc and that didn’t work out too well. The only way to save lives is to stamp it out by stopping the spread, meaning that it’s disappeared for good. It’s a mutated illness, one that usually is only found in animals. If we can stamp it out across the human population with a worldwide effort, and change practices on working with animal products, then in theory it’s gone for good. Herd immunity on this tiny island, when nobody else is doing this is, quite frankly - bollocks.
