I think efficacy is usually defined as preventing symptoms, a higher bar than preventing hospitalizations. I believe most vaccines were extremely successful at preventing hospitalizations.

Edit: Pfizer's primary endpoint was efficacy against lab-confirmed Covid-19 [1].

This is pure anecdata, but I’m hearing nearly daily from a friend in Indonesia about someone he knows dying of Covid. They’ve all had their sinovac shots.
