Getting vaccinated after successful recovery even improves immunity against Covid-19 reinfection. So there is a medical benefit in vaccinating the recovered. Also, it is extremely hard to scientifically and politically account for recovery as proof of vaccination. In some European countries, it sort of works, when you have good standards on how exactly to determine and track infection and recovery. Even then there are tradeoffs, because the immunity after vaccination is much better studied and much more predictable.
