💉Vaccines mimic viral infection to trigger an immune response.
🔬Influenza vaccines contain inactivated viral particles.
👥Macrophages, T cells, and B cells are involved in the immune response.
🧪Vaccines stimulate the production of antibodies and memory B cells.
🔒Hemagglutinin antibodies block viral attachment to host cells.
How do vaccines trigger an immune response?
—Vaccines mimic viral infection, stimulating the immune system to produce a response to protect against future infections.
What are the key components of influenza vaccines?
—Influenza vaccines contain inactivated or killed viral particles.
Which cells are involved in the immune response triggered by vaccines?
—Macrophages, T cells, and B cells play crucial roles in the immune response triggered by vaccines.
What is the role of antibodies in the immune response?
—Antibodies, produced in response to vaccines, help to neutralize pathogens and prevent their entry into host cells.
How do hemagglutinin antibodies work?
—Hemagglutinin antibodies block viral attachment to host cells, reducing the severity of the disease.
