Understanding the Immune System and Vaccines

What is the primary function of antibodies in the immune system?

• To mark antigens for destruction

• To produce antigens

• To destroy viruses directly

• To replicate viruses

How do traditional vaccines help the immune system?

• By directly attacking viruses

• By exposing the immune system to antigens

• By increasing the number of white blood cells

• By reducing the number of antigens

What do some vaccines contain to stimulate the immune response?

• Antibodies

• Weakened or dead viruses

• Active viruses

• White blood cells

What is the role of mRNA in mRNA vaccines?

• To destroy antigens

• To instruct cells to produce specific protein antigens

• To replicate viruses

• To increase white blood cell count

What is the fundamental idea behind all vaccines?

• To directly destroy viruses

• To decrease the number of white blood cells

• To increase the number of antigens

• To expose the immune system to an antigen
