> If you peer deeper, you’ll generally find this: The vaccinated remain substantially protected against serious illness or death, but the unvaccinated are entering the hospital and dying at very high rates indeed, as if to compensate .... If this is just Delta being more dangerous, then we would expect countries with lower vaccination rates to be enduring truly staggering mortality right now, but they are not. In heavily vaccinated countries, Delta is raging with a rare fury among the unvaccinated, but in lesser-vaccinated countries it is doing nothing unusual. This means that the efficacy statistics are broadly unreliable. The exact reasons don’t really matter: Either the vaccines have the power to change the whole picture, or they don’t.
