Hello docs, i'm a physician assistant student and did hernia checks on boys today. caught covid in december of 2019 and recovered. confirmed antibodies. i was wearing n95, face shield, and surgical mask. any data on chance of reinfection?

If your statement is accurate in timeline, Dec 2019, did you contract Covid-19 in China? Or it's a typo, you meant Dec 2020. Reinfection is rare and likely not severe, especially you had confirmed antibodies because of the memory in your immune system (B and T cells). By the recent literature, you will need only one dose of Pfizer or Moderna and you can mount a 50 time higher in antibody response.

Probably not. I would have the vaccines if possible., not just relying on your Covid 19 experience.
