Understanding the Immune System and Vaccines

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

• To replicate viruses

• To destroy viruses directly

• To mark antigens for destruction

• To produce antigens

How do traditional vaccines help the immune system?

• By directly destroying pathogens

• By causing a mild form of the disease

• By exposing the immune system to antigens

• By increasing the number of white blood cells

What do some vaccines contain to stimulate the immune system?

• Weakened or dead viruses

• Live bacteria

• Antibiotics

• Active viruses

What is the role of mRNA in mRNA vaccines?

• To instruct cells to produce a specific protein antigen

• To directly attack viruses

• To increase the number of white blood cells

• To replicate the virus

How do muscle cells respond to mRNA in vaccines?

• They replicate the mRNA

• They destroy the mRNA

• They ignore the mRNA

• They read the mRNA and produce a viral protein
