Question

If parents in the United States decline or delay vaccinations for their children because they fear the refuted claim of a link between vaccinations and autism, which of the following is a possible result?
a. A decrease in diagnosis of autism with a decrease of vaccinations
b. An increase in diagnosis of autism with an increase of vaccinations
c. An increase in the administration of subunit vaccines
d. A decrease in herd immunity
e. An increase in public demand for inactivated vaccines

Accepted Answer

Step 1: Understand the context of the problem, which involves parents declining or delaying vaccinations due to fear of a disproven link between vaccines and autism. Step 2: Recall that vaccines protect the population by creating herd immunity, which occurs when a high percentage of individuals are immunized, reducing the spread of contagious diseases. Step 3: Recognize that if vaccination rates decline, herd immunity weakens because fewer individuals are protected, increasing the risk of disease outbreaks. Step 4: Evaluate each answer choice in relation to the effect of declining vaccination rates: a decrease in autism diagnosis is unrelated to vaccination rates; an increase in autism diagnosis with more vaccinations is based on a refuted claim; increased use of subunit or inactivated vaccines is not a direct consequence of declining vaccination rates; a decrease in herd immunity logically follows from fewer vaccinations. Step 5: Conclude that the most scientifically supported result of declining vaccination rates is a decrease in herd immunity, which can lead to increased vulnerability to infectious diseases.
