Yeah it means quarantining old sick people. Their own space not in an institution. They will die and the rest of us won’t if exposed to covid19.
In fact to get herd immunity 60% of the healthy need to be exposed. This SiP crap for the healthy just delays the inevitable.
There is no vaccine and there won’t be an effective one in 4 years maybe.
Everyone needs to be exposed. Quarantine the sick and vulnerable. The rest will be exposed. It is going to happen even if all those hoping for a vaccine hold their breath and hide at home for the next 4 years.
