“ Low levels of the virus remained in the mice that received the antibody, but those levels didn't increase and signs of rabies did not immediately return, the results showed.” I’m a little troubled by this outcome. Having the virus linger longer in a living host — is there chance it could mutate or exchange genetic material with another virus like an airborne one? I don’t know how we would even measure when a human is truly cleared the virus; in mice they know because of an autopsy.
