Plain-English summary
A group of dogs received an experimental oral vaccine designed to protect against canine parvovirus (CPV), a serious virus that can cause severe gastrointestinal issues. After vaccination, the dogs showed a strong immune response, producing specific antibodies that can help fight off CPV. This study suggests that this new oral vaccine could be a promising option for vaccinating dogs against this dangerous virus.

Abstract
A Sindbis virus replicon-based DNA vaccine containing VP2 gene of canine parvovirus (CPV) was delivered by Escherichia coli to elicit immune responses. The orally immunized dogs developed CPV-specific serum IgG and virus neutralizing antibody responses. The cellular immune responses analyzed using lymphocyte proliferation test and flow cytometry indicated CPV-specific sensitization of both CD3+CD4+ and CD3+CD8+ lymphocytes. This study demonstrated that the oral CPV DNA vaccine delivered by E. coli can be considered as a promising approach for vaccination of dogs against CPV.
