The Salk vaccine was a _KILLED_ virus vaccine, created by Jonas Salk. Several years later, Albert Sabin created a weakened _LIVE_ virus vaccine, called, not surprisingly, the Sabin vaccine. Its purpose was not to spread to "non-vaccinated" people. It was designed neither to spread not to make people sick; just to do a better job of getting the immune system to create antibodies to polio than did the Salk vaccine. Being a killed virus, and barring an error in the creation of the killed virus vaccine, the Salk vaccine could neither spread nor make anyone sick. (With both vaccines, and indeed with almost any vaccine, it is possible that the manufacture of the vaccine might be defective, leaving live unweakened virus. _VERY UNLIKELY_. It is further possible, and more likely but still unlikely, that any particular person can have an allergic reaction to a vaccine, and get sick, sometimes very sick.)

You're right, of course. I always have trouble keeping these two straight. >Several years later, Albert Sabin created a weakened _LIVE_ virus >vaccine, called, not surprisingly, the Sabin vaccine.

I am afraid you need to do a little more research on this. The government policy pushing the live-virus vaccine (Sabin) in favor of the killed- virus vaccine emphasizes the ability of the live-virus vaccine to spread to non-vaccinated children, spreading the benefits. There have been several popular accounts of this as well, including one episode on Nova (PBS). If you wish to discuss this further. let us move it to email or sci.medicine.
