Maternal-fetal interface yields intriguing clues to how it battles SARS-CoV-2

Scientists have hypothesized that the number of immune cells and the amount of cytokines produced in response to SARS-CoV-2 infection in pregnant women change in accordance with the timing of maternal infection in pregnancy. This study is available on the bioRxiv* preprint server.

Limited immune responses three months after Pfizer-BioNTech vaccination among elderly

In this study, published on the medRxiv* preprint server, the humoral response to SARS-CoV-2 was assessed before and after three months of administration of the BNT162b2 mRNA COVID-19 vaccination (Pfizer-BioNTech). In addition, elders' humoral responses were compared to those of a younger group, and a functional neutralization experiment against the Wuhan-Hu-1 (WH1) virus and the Delta variant was carried out.
