new polio vaccine recommendations
There's bound to be some confusion over the new polio vaccine recommendations.
Starting in '97, the CDC recommends using the INJECTABLE inactivated polio vaccine (IPV) for the first 2 doses...followed by 2 doses of the oral polio vaccine (OPV).
This is to reduce the risk of paralytic polio in susceptible children or their contacts. The injectable vaccine doesn't contain live virus so it can't cause polio.
