Limited data exists on the temporal trend of the Sars-CoV-2 immunologic response and duration of protection following natural infection. We sought to investigate the presence and duration of Sars-CoV-2 serum antibodies in obstetrical healthcare workers (HCW) on serial assessments over a 6-month period, and to assess rates of vaccine acceptance and reported vaccine side effects among this cohort.

关于 Sars-CoV-2 免疫反应的时间趋势和自然感染后的保护持续时间的数据有限。我们试图通过为期 6 个月的系列评估调查产科医护人员 (HCW) 中 Sars-CoV-2 血清抗体的存在和持续时间，并评估该队列中的疫苗接受率和报告的疫苗副作用。
