Poliovirus replication competent recombinant Sabin type 1 strain

摘要

A replication-competent recombinant Sabin type 1 poliovirus vector containing a sequence coding for multiple cloning site and 3C-protease cleavage site is provided. This vector makes it easy to introduce various vaccine genes from infectious viruses to the Sabin 1 poliovirus, and facilitates to produce chimeric Sabin 1 polioviruses that are expected to be powerful oral mucosal vaccines against several infectious viral diseases.
