Abstract
After eradication and containment of wild poliovirus (PV) and cessation of oral polio vaccinations, it is critical to minimize the risk of reintroducing PV into PV-free communities via facilities that handle the virus. The potential risk of unintentional PV propagation through unidentified contaminated materials is a serious issue. This study reports the generation of HeLa and RD-A cells deficient in functional CD155 gene (∆PVR cells); these cells are not susceptible to PV but remain susceptible to other picornaviruses. These ∆PVR cells will minimize the risk of unintentional transmission of PV and support performing the experiments more safely.
