Which of the following is true of the Sabin vaccine against the polio virus?

Question

Quizplus · Accepted Answer

The Sabin vaccine contains a mutated form of the polio virus which is temperature sensitive, meaning it can only replicate at cooler temperatures in the gut but not in the warmer temperatures of the spinal cord. This makes the vaccine safer than the Salk vaccine, which contains inactivated virus, because there is no risk of the weakened live virus in the Sabin vaccine causing the disease itself. Option A is incorrect because the Salk vaccine is the one which contains inactivated virus. Option C is incorrect because the Sabin vaccine contains a weakened form of the virus rather than a small amount of the natural virus.
