Question

The Salk Vaccine. In Exercise 1.17 on page 8, we discussed the Salk vaccine experiment. The experiment utilized a technique called double-blinding because neither the children nor the doctors involved knew which children had been given the vaccine and which had been given placebo. Explain the advantages of using double-blinding in the Salk vaccine experiment.

Short answer

• lowers the chance of a doctor's biased diagnosis.
• Help doctors maintain track of such a large number of grade school children.

Step-by-step solution

Step 1. Given information.

The given statement is:

In Exercise 1.17 on page 8, we discussed the Salk vaccine experiment. The experiment utilized a technique called double-blinding because neither the children nor the doctors involved knew which children had been given the vaccine and which had been given a placebo.

Step 2. Advantages of using double-blinding in the Salk vaccine experiment.

The benefits of utilizing double-blinding in the Calk vaccination study are as follows:

1. Such a process aids in entirely randomizing grade-school students, as well as lowering the chance of a doctor's biased diagnosis.
2. Because the evaluation center is in charge of keeping a track of such a large number of grade school children, such a technique would also lessen the work required by doctors to maintain track of such a large number of them.
