Detailed investigation of B cell populations following vaccination and infection with severe acute respiratory syndrome coronavirus-2 during pregnancy
To enhance the comprehension of the immunological consequences of vaccination and/or infection during pregnancy, focusing on alterations in B cell populations in women at term, which is crucial for maternal and fetal health.
Approach:
Key Findings:
Serum levels of APRIL, IL-4, IL-6, TNF-α, and sCD40L varied based on vaccination and infection status.
Vaccination altered the frequency of plasma blasts, plasma cells, and B memory cells.
Infected patients showed increased IL-10+ B cells and decreased IL-6+ B cells compared to vaccinated women.
Infection induced CD40 expression in B cells, while vaccination enhanced PD-1, FasL, and CD86 expression.
Interpretation:
SARS-CoV-2 infection and vaccination during pregnancy significantly shift the balance between pro- and anti-inflammatory B cell populations and modify costimulatory molecule expression.
Limitations:
The study does not address the long-term consequences of altered B cell populations.
Limited demographic data on the participants may affect generalizability, and potential biases in sample selection or measurement methods were not discussed.
Conclusion:
Further investigation is needed into the long-term consequences of maternal SARS-CoV-2 immunity for both mothers and offspring, emphasizing the importance of these findings for future research and clinical practice.
