Antibodies are immunoglobulins produced by B lymphocytes during their differentiation into plasma cells that bind specifically to the corresponding antigen. Antibodies can be divided into five major classes (IgG, IgA, IgM, IgD, IgE), which have a protective effect on the organism. Antibody mRNAs don't require nuclear localisation to mediate protein translation, but can be translated directly into target proteins or immunogenic activation of the immune response in vivo by using genetic sequence of the virus.https://mrna.creative-biolabs.com/category-antibody-mrna-479.htm
