Abstract Mucosa-associated invariant T (MAIT) cells are unconventional T cells with innate-like capacity to rapidly respond to microbial infection via MR1-restricted antigen recognition. Emerging evidence indicate that they can also act as rapid sensors of viral infection via innate cytokine activation. However. their possible role in the immune response to mRNA vaccination is unknown. https://www.roneverhart.com/SAAB-9-3-I-98-02-Frontlykt-Hoyre/
