Clinical Trial Summary

The clinical presentation of the ongoing coronavirus disease-19 (COVID-19) pandemic in pregnant women is unique with more asymptomatic infection, higher morbidity when symptomatic, yet without a difference in mortality rate. This is strikingly different from the high mortality observed during the past influenza A pandemics. Though both influenza A virus (IAV) and SARS-CoV-2 are single-stranded RNA viruses, the exquisite vulnerability of pregnant women to influenza A but not COVID-19 remains a mystery. Our objective, therefore, is to determine the mechanisms that predispose pregnant women to severe influenza A but confer protection against SARS-CoV-2 infection by examining the viral entry factors and innate immune response mechanisms in the nasal epithelium of pregnant vs. non-pregnant age-matched women.
