Brunhilde virus: Type 1 rel=dict poliovirus. Named after a female chimpanzee from which it was first isolated. There are two other strains of poliovirus: Type 2 (known as the rel=dict Lansing virus) and Type 3 (known as the rel=dict Leon virus). Immunity to one strain does not provide protection against the other two. All three strains are therefore included in the poliovirus vaccine.
