The Salk Vaccine

Question

The Salk vaccine
A)contains live attenuated virus.
B)contains inactivated virus.
C)contains a portion of the polio virus.
D)occasionally causes disease.

Accepted Answer

The Salk vaccine contains inactivated virus, which means the virus is no longer able to cause disease. This is different from a live attenuated vaccine, which contains a weakened form of the virus that is still able to replicate and stimulate an immune response. The Salk vaccine is an important tool in the eradication of polio, as it has been shown to be highly effective in preventing the disease.
