parentologist:

This study was to determine and compare antibody response to first dose of Pfizer vaccine in healthcare workers who hadn’t already had Covid, vs those who had recovered from real Covid infection. Incidentally, they reported nice antibody response in the Covid-naive workers 3 weeks after that first dose.

Based on the image included in that study:

It looks like (in the bottom section of the image) one dose of vaccine in those with no history of infection resulted in highly variable “Blocking of Binding of Receptor-Binding Domain to ACE2”, similar to history of infection before vaccination. However, previously infected people who got one dose of vaccine had uniformly high blocking of binding, except for one unlucky person.
