Imagine you are preparing for the upcoming flu season. What is the primary function of getting a flu vaccine?

• To cause the flu

• To fight against the flu by building immunity

• To weaken the immune system

• To replace flu medications

Answer explanation

Vaccines work by fighting against infections and building immunity, not by causing disease, weakening the immune system, or replacing antibiotics.

How do vaccines work to protect us from diseases?

• By causing the diseases they aim to prevent

• By introducing weakened or dead pathogens to stimulate an immune response

• By providing a permanent cure for diseases

• By suppressing the immune system

Answer explanation

Vaccines work by introducing weakened or dead pathogens to stimulate an immune response, helping the body develop immunity without causing the disease.

Imagine you've previously caught the flu, and the next year, the same strain tries to infect you again. What role do memory cells play in this scenario within your immune system?

• They directly attack the flu virus

• They weaken over time and forget the previous flu infection

• They are only active in children and not in adults

• They remember the flu infection and quickly coordinate an immune response upon re-exposure

Answer explanation

Memory cells in the immune system remember past infections, allowing for a quicker and more coordinated immune response upon re-exposure to the same pathogen.

Why are vaccines important for children?

• Children have a naturally strong immunity against diseases

• Vaccines cause more diseases in children than they prevent

• Children's immune systems are still developing and vaccines help build their immunity

• Vaccines are only effective in adult populations

Answer explanation

Children's immune systems are still developing and vaccines help build their immunity

In the context of a global pandemic, what does herd immunity refer to?

• The immunity one gets from being in a crowd during a large event

• A form of immunity that occurs when a significant portion of a population becomes immune to a disease, thereby providing a measure of protection for individuals who are not immune

• A condition where individuals are immune to diseases commonly found in herd animals

• A type of vaccine designed for widespread use in a population

Answer explanation

Herd immunity is a form of immunity that occurs when a significant portion of a population becomes immune to a disease.
