Injected/killed: The live weakened oral polio vaccine was the USA standard from the late early 60's until the early 90's. There was a low, but real risk of polio (1/1-2 million doses) with the oral vaccine that was not present with the enhanced injected vaccine. By the late 90's, the oral polio vaccine was not available to most physicians and the injected became the standard.
