The evaluation of breakthrough infection and humoral immunity responses are important outcomes for vaccination policy healthcare staff. This prospective cohort study collected blood samples at 5-time points; before primary vaccine doses, 2, 10 24 weeks after BNT162b2 from 551 HCWs, between March October 2021. We investigated the association anti-spike-1 protein receptor-binding domain (anti-S1-RBD) antibody geometric mean titre (GMT) infections. Two post-vaccination, GMT anti-S1-RBD...
Asymptomatic severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infections are well documented. Healthcare workers (HCW) at increased risk of infection due to occupational exposure infected patients. We aim determine the prevalence SARS-CoV-2 antibodies among HCW who did not come medical attention.We prospectively recruited 400 from National Public Health Laboratory and two COVID-19 designated public hospitals in Klang Valley, Malaysia between 13/4/2020 12/5/2020. Quota sampling...
Abstract IntroductionHealthcare workers (HCW) are presumed to be at increased risk of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection due occupational exposure infected patients. We aim determine the prevalence anti-SARS-CoV-2 antibodies among asymptomatic HCW.MethodsWe prospectively recruited HCW from National Public Health Laboratory and two COVID-19 designated public hospitals in Klang Valley, Malaysia between April 13th May 12th, 2020. Quota sampling was applied...
ObjectivesTo study the incidence of Omicron infections in Malaysia and exposures that could reduce hazard attaining infection.MethodsWe used a multicenter, prospective cohort to 482 healthcare workers vaccinated with two three doses BNT162b2 for SARS-CoV-2 infection during Omicron-dominant period Malaysia.ResultsBetween January 31 July 31, 2022, cumulative was 44.6% (95% CI 40.2-49.1%), rate 3.33 2.91-3.80) per 1000 person-days. Our found protection against significantly higher persons...
Abstract This study assessed the association between COVID-19 vaccines, SARS-CoV-2 infection and risk of thrombocytopenia venous thromboembolism (VTE). self-controlled case series used hospital records 1st February 2021 28th 2022 linked to national immunisation registry surveillance data in Malaysia. Conditional Poisson regression was estimate incidence rate ratios (IRR) events period (day 1–21 post-exposure) relative control with corresponding 95% confidence interval (CI) adjusted for...
