Detailed immune monitoring of a pregnant woman with critical Covid-19.

ABSTRACT: A primigravid woman with Covid-19 related respiratory insufficiency was admitted into a tertiary Intensive Care Unit at 23 3/7 weeks' gestation. Highly sensitive flow cytometry of peripheral leukocytes indicated significantly suppressed naïve T- and B-cell compartments. The suppressed immune cell responses led us keep the initially started administration of corticosteroids for fetal and maternal indication at a low dose. After three weeks her B-cell response peaked, SARS-CoV-2 was cleared and clinical improvement ensued a week later. At 28 weeks' gestation, a son of 1570 g was born by cesarean section. She was extubated two days postpartum and discharged from hospital 5.5 weeks postpartum.

Project description:The COVID-19 pandemic has prompted vaccine development efforts on an unprecedented scale. Vaccines based on mRNA technology have emerged as particularly attractive due to their high efficacy and short development timelines. However, relatively little is known about the factors contributing to the development of protective immunity by this new class of vaccines. We employed a high-temporal-resolution transcriptome profiling approach to investigate responses to COVID-19 mRNA vaccination. A cohort of 23 subjects was recruited and changes in blood transcript abundance were measured daily for 9 days post-priming and post-booster vaccination via RNA sequencing. Antibody responses were measured on days 7 and 14 post-vaccination using a custom multiplex assay. Marked differences were observed between responses to the priming and booster doses, with the latter inducing widespread changes in blood transcript abundance consistent with those found in patients with acute viral respiratory infections. The delineation of interferon responses at a high-temporal frequency also suggested that the priming and booster doses elicited distinct types of responses that peaked on day 2 post-priming dose and day 1 post-booster dose. The booster dose also induced inflammation on day 1 and erythroid cell signatures as well as an atypical plasmablast signature on day 4. Notably, this plasmablast signature, together with the post-booster interferon response signature, correlated with the antibody response levels induced on day 14 after the booster dose. Taken together, this work provides a detailed map of the antibody and transcriptional responses to the first and second doses of a new class of vaccine and yields important insights into the mechanisms underlying their immunogenicity. Furthermore, our results suggest that implementing high-temporal-frequency immune profiling protocols may provide an opportunity to better resolve the immune responses elicited by the growing number of available COVID-19 vaccines.
