Worked Solution & Example Answer:Why are polio vaccinations effective? (A) They cause an inflammation response resulting in the production of antibodies that engulf the polio virus if it enters the body - HSC - SSCE Biology - Question 5 - 2008 - Paper 1
Step 1
They cause an immune response resulting in the production of memory B cells that provide a rapid response if infected by the polio virus.
Answer
The correct answer is (C). Polio vaccinations are designed to stimulate an immune response in the body that leads to the production of memory B cells. These memory B cells remain in the body long after vaccination and enable a swift and effective response if the individual encounters the polio virus in the future. This rapid response is crucial in preventing the virus from causing illness. In contrast, options (A), (B), and (D) do not effectively explain the primary mechanism of action for polio vaccinations.
