How is the DTaP/IPV/Hib vaccine different from the previous primary vaccinations?
• The polio vaccine does not contain a live virus, so it no longer carries the slight risk of causing vaccine-associated paralytic polio. The vaccine uses inactivated polio vaccine (IPV) instead of live oral vaccine. ‘Inactivated’ means that the viruses contained in the vaccine have been killed, so that they can’t harm you.
