Aspects of the invention relate to methods for producing an antigen-specific immune response to human cytomegalovirus (hCMV) in a subject by administering mRNA vaccines comprising hCMV antigenic polypeptides gH, gL, UL128, UL130, UL131 A and gB formulated in lipid nanoparticles, wherein the antigen-specific immune response to hCMV results in neutralizing antibodies that have i) a geometric mean titer of at least 3-fold against epithelial cell infection or ii) a geometric mean ratio of 9-41 against epithelial cell infection or iii) a geometric mean ratio of 4-8-fold against fibroblast infection.

Provided herein are, inter alia, compositions including recombinant oncolytic herpes simplex viruses that express SARS-CoV spike (S) protein and viral vectors including nucleic acid sequences encoding SARS-CoV S protein. The compositions are useful for eliciting antibodies to SARS-CoV. The compositions are contemplated to be particularly useful for methods of treating and preventing SARS coronavirus infections in cancer patients.
