To assess the effectiveness of the vaccine against SARS-CoV-2 (BNT162b2) in healthcare personnel of a health department.
Test-negative case̶control study. Healthcare personnel with suspected COVID-19 and healthcare personnel close contacts of COVID-19 cases were included between January 27th and June 6th, 2021. They were PCR tested for SARS-CoV-2; those with positive PCR were considered cases and those with negative PCR were considered controls. The adjusted vaccine effectiveness (aVE) to prevent COVID-19 cases and their 95% confidence interval (95%CI) were calculated using the formula VE=(1-odds ratio)×100.
624 healthcare personnel were included, of which 43 (6.9%) were considered cases and 581 (93.8%) controls. The aVE of the complete regimen was 96.3% (95%CI: 82.5̶99.2). The aVE of the incomplete pattern was 68.0% (95%CI: 30.0̶85.4).
The administration of the complete pattern of BNT162b2 vaccine against SARS-CoV-2 is effective for the prevention of cases of COVID-19 in healthcare personnel.
评估针对严重急性呼吸综合征冠状病毒2(SARS-CoV-2)的疫苗(BNT162b2)在某卫生部门医护人员中的有效性。
检测阴性病例对照研究。纳入2021年1月27日至6月6日期间疑似新型冠状病毒肺炎(COVID-19)的医护人员以及COVID-19病例的医护密切接触者。对他们进行SARS-CoV-2的聚合酶链反应(PCR)检测;PCR结果呈阳性者被视为病例,PCR结果呈阴性者被视为对照。使用公式VE =(1 - 比值比)×100计算预防COVID-19病例的调整后疫苗效力(aVE)及其95%置信区间(95%CI)。
纳入624名医护人员,其中43名(6.9%)被视为病例,581名(93.8%)为对照。完整接种方案的aVE为96.3%(95%CI:82.5 - 99.2)。不完整接种模式的aVE为68.0%(95%CI:30.0 - 85.4)。
接种完整模式的针对SARS-CoV-2的BNT162b2疫苗对预防医护人员中的COVID-19病例有效。
