Vaccines are the most effective strategy to control the spread of coronavirus disease-2019 (COVID-19). Data on COVID-19 among healthcare workers (HCW) pre- and postvaccination are limited. This study aims to evaluate the clinical characteristics and outcomes of HCW with COVID-19 pre- and postvaccination. Retrospective cohort study. All HCWs with suspected COVID-19 were included. Demographic data, occupation, symptoms, work in COVID-19 area, and vaccination status were collected. There were 22 267 HCW visits for suspected COVID-19; 7879 (35.4%) tested positive, and 14 388 (64.6%) tested negative. Fever, cough, fatigue, and dyspnea were positive predictors of COVID-19, and sore throat, headache, coryza, work in a COVID-19 area, and COVID-19 vaccination were negative predictors. Of the total number of visits, 41.2% were from vaccinated HCW and 58.8% were from unvaccinated HCW. Among HCWs with COVID-19, 84 (1.1%) required hospitalization, 11 (0.1%) in an intensive care unit (ICU), with three (0.04%) deaths. Six hospitalizations occurred in vaccinated HCWs, being of short duration, with no need for ICU admission and no deaths. SARS-CoV-2 infection prevalence was high among HCW, and vaccinated HCW had fewer hospitalizations, need for ICU, and deaths. Therefore, vaccines may attenuate COVID-19 severity, and efforts must be concentrated to ensure adequate vaccination for HCW.

Serological studies uniquely strengthen infectious disease surveillance, expanding prevalence estimates to encompass asymptomatic infections, and revealing the otherwise inapparent landscape of immunity, including who is and is not susceptible to infection. They are thus a powerful complement to often incomplete epidemiological and public health measures (administrative measures of vaccination coverage, incidence estimates, etc.).

Background: Despite advancements in understanding the interplay between systemic lupus erythematosus (SLE), cardiovascular disease and COVID-19, challenges and knowledge gaps persist. This study aimed to characterize the cardiovascular profiles of SLE patients hospitalized with COVID-19 and to evaluate the influence of SLE on the development of cardiovascular complications.
Methods: This was a multicentre, nationwide observational study in which data were sourced from the SEMI-COVID-19 Registry between March 1, 2020, and March 31, 2021, involving 150 Spanish hospitals.

Single nucleotide variations (SNVs) and polymorphisms (SNPs) are characteristic biomarkers in various biological contexts, including pathogen drug resistances and human diseases. Tools that lower the implementation barrier of molecular SNV detection methods would provide greater leverage of the expanding SNP/SNV database. The oligonucleotide ligation assay (OLA) is a highly specific means for detection of known SNVs and is especially powerful when coupled with polymerase chain reaction (PCR).
