The US Department of Health and Human Services has a stated goal for the seasonal influenza vaccine of vaccinating 80% of healthy (i.e., low-risk) individuals. This vaccine is formulated each year from the serotypes of influenza likely to be circulating in the population during the coming flu season. The reason this goal is not 100% of individuals is because:
A) It is not feasible to expect 100% of healthy individuals to get the flu vaccine every year.
B) Individuals who had the flu vaccine the year before will already be protected.
C) Individuals who are healthy need not be too concerned about getting infected with flu.
D) Healthy individuals are unlikely to spread the virus to others.
E) Unvaccinated individuals are protected when 80% of people around them are vaccinated.
