Materials Map under construction

The Materials Map is still under development. In its current state, it is only based on one single data source and, thus, incomplete and contains duplicates. We are working on incorporating new open data sources like ORCID to improve the quality and the timeliness of our data. We will update Materials Map as soon as possible and kindly ask for your patience.

Abstract

<jats:title>A<jats:sc>BSTRACT</jats:sc></jats:title><jats:sec><jats:title>Context:</jats:title><jats:p>The COVID-19 vaccination drive globally was supposedly a game-changing event. However, the emerging variants of the virus and waning immunity over time posed new challenges for breakthrough infections. Standing at the frontline of defense against COVID-19, healthcare personnel (HCP) were vulnerable to such infections.</jats:p></jats:sec><jats:sec><jats:title>Aims:</jats:title><jats:p>This study estimates i) the vaccine breakthrough infections (VBI) among HCP following exposure to COVID-19 cases, and ii) the mean interval between the second dose of vaccine and laboratory-confirmed SARS-CoV-2 infection</jats:p></jats:sec><jats:sec><jats:title>Materials and Methods:</jats:title><jats:p>A cross-sectional study was conducted including 385 HCP with a history of exposure to COVID-19 cases during January and February 2022. Demographic details and clinical and vaccination history were collected from the test forms and the Web-based hospital management system. Laboratory testing of COVID-19 was carried out by real-time RT-PCR test.</jats:p></jats:sec><jats:sec><jats:title>Results:</jats:title><jats:p>The majority of the HCP were males (262; 68.05%) and nurses (180; 46.75%) by occupation. Two doses of vaccines were received by 278 (87.7%) HCP. VBI was confirmed in 185 (66.55%) HCP. No significant difference in VBI between the COVAXIN and COVISHIELD recipients (<jats:italic toggle="yes">P</jats:italic> = 0.69) was observed. The interval between the second dose and confirmed SARS-CoV-2 infection was significantly higher (<jats:italic toggle="yes">P</jats:italic> &lt; 0.00001) in COVAXIN recipients (median 228 days) than in COVISHIELD recipients (median 95 days).</jats:p></jats:sec><jats:sec><jats:title>Conclusions:</jats:title><jats:p>The incidence of VBI was very high among the HCP, but not statistically different among the COVAXIN and COVISHIELD-recipients. Waning immunity over time suggests boosting immunity with a third dose because of emerging variants.</jats:p></jats:sec>
