A recent study by Emory University researchers provides new insights into why the mRNA vaccines developed to fight COVID-19 in 2021 are less effective in patients with autoimmune diseases. By providing insights into the cellular processes behind that lessened protection, the new study published in Nature Immunology, highlights that lupus patients may require tailored vaccination strategies to enhance protection against COVID-19. The findings could also offer insights into the potential and limits of alternative ways to create immunity to COVID-19 through vaccines.
The study provides the first evidence that vaccine-induced responses generate a novel type of memory B cell. These newly discovered cells could contribute to booster responses and infection protection. However, their role in ensuring long-term…
