The study conducted in Morocco focused on addressing the challenges posed by canine parvovirus (CPV-2) through comprehensive research, vaccine development, and efficacy assessment. Through real-time PCR screening and genotyping, CPV-2 variants were identified circulating in the region. An inactivated vaccine, derived from a CPV-2 strain isolated from a symptomatic dog, was produced and evaluated for safety and efficacy. The vaccine, from the strain named “CaPV M/3-2022”, demonstrated safety in vaccinated puppies, with no adverse reactions observed during the trial period. Efficacy trials showed that vaccinated puppies remained healthy and exhibited lower viral excretion post-challenge compared to unvaccinated controls. These results indicate that the vaccine effectively protects against illness related to CPV-2 and reduces viral shedding. The study provides valuable insights into CPV-2 epidemiology in Morocco, offers a promising vaccine solution, and underscores the importance of vaccination in controlling CPV-2 outbreaks and protecting canine health.
