I want to see more studies, but:

Study shows prior exposure to #SARSCoV2 does not guarantee high level of antibodies, nor does it guarantee robust antibody response to first vaccine dose.

The findings support vaccination (& 2 doses), even for people who have previously been infected.https://t.co/SikXnjAeAx
