Delaying herd immunity is costing lives

Considering these numbers, people above 60 must be better protected, while restrictions should be loosened on those below 50. Older people who are vulnerable should stay at home. Food should be delivered and they should receive no visitors. Nursing homes should be isolated together with some of the staff until other staff who have acquired immunity can take over. Younger people should go back to work and school without older coworkers and teachers at their sides.

While the appropriate magnitude of countermeasures depends on time and place as it is necessary to avoid hospital overload, the measures should still be age-dependent. This is how we can minimise the number of deaths by the time this terrible pandemic is over.

Among anti-herders, it is popular to compare the current number of Covid-19 deaths by country and as a proportion of the population. Such comparisons are misleading, as they ignore the existence of herd immunity. A country much closer to herd immunity will ultimately do better even if their current death count is somewhat higher. The key statistic is instead the number of deaths per infected. Those data are still elusive, but comparisons and strategies should not be based on misleading data just because the relevant data are unavailable.
