40 Questions
Which of the following best describes herd immunity?
Resistance of a group to a disease due to the immunity of a large proportion of its members
What is the purpose of vaccinating a portion of the population?
To provide economic benefits to society
What does vaccine efficacy predict?
The percentage reduction in disease occurrence in a vaccinated group compared to an unvaccinated one
Why is it challenging to reveal the vaccine efficacy for diseases with low incidence rates?
Because clinical trials require a massive number of incidence rates
What would be required for vaccine evaluation in clinical trials?
A placebo control group and multiple trial arms
What contributes to the effectiveness of vaccines?
Individuals' immune response
What happens when a large proportion of a population is vaccinated?
The pathogens find it difficult to find a host to infect
What is the relationship between vaccination and herd immunity?
Vaccination is necessary to achieve herd immunity
What does vaccine efficacy help decide?
Whether a vaccine provides protective immunity within an individual and a community
Why may administering vaccines to large communities take a long time?
Because it requires organizing vaccination campaigns
Which diseases have vaccines significantly curtailed since their introduction?
Smallpox, diphtheria, and polio
What is the primary goal of vaccines?
To develop a longer-lasting immune response
What is the role of antigen-presenting cells (APCs) in the immune response to vaccines?
To process vaccine particles internally
What occurs when the cells of the body's immune system recognize epitopes or moieties associated with the vaccine antigen?
The immune response is initiated
What is the purpose of T cell-dependent or protein antigen maturation of B cells?
To develop a humoral immune response
What is herd immunity or herd protection?
A strategy to enhance the significance of vaccines for the community
What is the role of vaccines in reducing the burden associated with diseases?
To prevent diseases caused by pathogens
What happens to the antigens within vaccines after they are injected into a patient?
They are recognized by the body's immune system
What is the function of the body's adaptive immune system in response to vaccines?
To develop a humoral immune response
What is the significance of vaccines for the community?
To prevent the spread of diseases
True or false: Vaccines have played a significant role in preventing diseases throughout history?
True
True or false: Vaccines only target deadly diseases and do not treat them as they occur?
True
True or false: Antigen-presenting cells (APCs) recognize and process vaccine particles internally?

True or false: Vaccine efficacy predicts the effectiveness of vaccines in preventing diseases?
True
True or false: Administering vaccines to large communities can be a time-consuming process?
True
True or false: The immune response to vaccines involves the recognition of antigens by the body's immune system cells?
True
True or false: The resistance of a group attacked by a disease is due to the immunity of a small proportion of the members.
False
True or false: Vaccinating a portion of the population can provide protection to the unvaccinated population.
True
True or false: Pathogens can transmit themselves to infect the vulnerable population even if there are no available hosts.
False
True or false: Vaccines can provide substantial economic benefits and protect society from severe virus infections.
True
True or false: The efficacy of vaccines predicts the percentage reduction in disease occurrence in a vaccinated group compared to an unvaccinated one.
True
True or false: Revealing the vaccine efficacy requires a massive number of incidence rates of the disease.
True
True or false: Clinical trials to validate vaccine efficacy against viruses are not affected by the incidence rate of the disease.
False

False
True or false: Vaccinating a portion of the population has no impact on the vaccines' effectiveness.
False
