Next-gen Vaccine Doesn't Contain Live Virus

November 13, 2014 2:00 pm | by The Univ. of Queensland | News | Comments

A polio inoculation in use since the 1950s has all-but eradicated the crippling disease in the developed world, but “wild polio” strains are running rampant in some poorer countries. Now, vaccine technology being developed by a team could hold the key to completely eradicating polio by removing live virus from the vaccine production process.
