A Representation of the PIV5 Virus |
The ride-along pathogen is destroyed--but now our bodies recognize it and can clobber it if it shows up again.
That's the theory, anyway. The idea of using a virus as a delivery mechanism for a vaccine isn't new--but with most viruses, our bodies destroy the virus and its ride-along pathogen so quickly that we don't gain any immunity.
PIV5 seems to be different from the viruses that have been previously tried. Scientists at the University of Georgia have been experimenting with it for 15 years and have achieved promising results with mice. Immunity to the virus does not seem to limit its effectiveness in either mice or humans.
