临床研究正在进行中,以评估现有疫苗是否可以通过训练免疫力提供对SARS-CoV-2感染的保护。在这项探索性研究中,我们分析了137,037名接受SARS-CoV-2 PCR检测的个人的免疫记录。我们发现脊髓灰质炎、B型流感嗜血杆菌(HIB)、麻疹-腮腺炎-风疹(MMR)、水痘、肺炎球菌结合物(PCV 13)、老年流感和甲型/乙型肝炎在过去的1年,2年和5年中接种的HepA-HepB疫苗与SARS-CoV-2感染率降低相关,即使在调整了SARS-CoV-2的地理发病率和检测率,人口统计学,合并症,其他疫苗的数量。此外,年龄、人种/种族和血型分层分析显示,接种PCV 13疫苗的黑人个体的SARS-CoV-2发病率显著较低,5年时间范围内的相对风险为0.45(n:653,95%CI(0.32,0.64),p值:6.9e−05)。总的来说,这项研究确定了现有的获批疫苗,这些疫苗可能是对抗COVID-19的临床前研究和随机临床试验的有希望的候选疫苗。
Clinical studies are ongoing to assess whether existing vaccines may afford protection against SARS-CoV-2 infection through trained immunity. In this exploratory study, we analyze immunization records from 137,037 individuals who received SARS-CoV-2 PCR tests. We find that polio, Haemophilus influenzae type-B (HIB), measles-mumps-rubella (MMR), Varicella, pneumococcal conjugate (PCV13), Geriatric Flu, and hepatitis A/hepatitis B (HepA–HepB) vaccines administered in the past 1, 2, and 5 years are associated with decreased SARS-CoV-2 infection rates, even after adjusting for geographic SARS-CoV-2 incidence and testing rates, demographics, comorbidities, and number of other vaccinations. Furthermore, age, race/ethnicity, and blood group stratified analyses reveal significantly lower SARS-CoV-2 rate among black individuals who have taken the PCV13 vaccine, with relative risk of 0.45 at the 5 year time horizon (n: 653, 95% CI (0.32, 0.64), p-value: 6.9e−05). Overall, this study identifies existing approved vaccines which can be promising candidates for pre-clinical research and Randomized Clinical Trials towards combating COVID-19.
