Why are these visits necessary? a. The baby is being vaccinated. b. The visits verify that the baby has a normal inflammatory response. c. The baby must have an unusual immune deficit that must be monitored. d. The baby’s blood is being filtered to remove foreign antigen.
Suppose a person recovers normally from viral infections, but then gets the same viral infections over and over again- unlike the rest of us.

B. Should this person be at a higher risk of cancer than the rest of us?
C. Should this person be able to lyse bacterial cells as well as the rest of us?

- Vaccines are given to provide protection against pathogen causing infections. Which of the following statements best describes how vaccines work? a Fever and swelling develop which is the first response in killing a pathogen b. Antibodies in the vaccine provide the body with nonspecific immunity to an antigen. c. An inactivated or killed virus stimulates the body to develop specific immunity to that type of virus. d. Heathy bacteria causes the body to release toxins which will protect the body if later exposed to different type of bacteria.arrow_forwardExplain why each choice (a-d) is correct or incorrect. Allergens differ from antigens because a. Allergens produce an abnormally large immune response to what is an otherwise harmless particle. b. Allergens do not involve the leucocytes, they simple stimulate the inflammatory response. c. Allergens are only active seasonally and are generally harmless to the body. d. Allergens are primarily plant derived while antigens are bacterial or viral in nature.arrow_forwardAntibodies against a specific antigen can be injected into a person to provide passive immunity. For which reason is this NOT as effective as the process of vaccination with that antigen? Select one: a. Injection of antibodies may cause allergic reactions, while vaccination never causes allergic reactions. b. Injection of antibodies does not provide long-lasting immunity, and vaccination with antigens triggers a clonal selection of B cells and cytotoxic T cells. c. Vaccination with antigens triggers a clonal selection of B cells and cytotoxic T cells. d. Injection of antibodies does not provide long-lasting immunity. e. Injection of antibodies does not provide long-lasting immunity and may cause allergic reactions, while vaccination never causes allergic reactions.arrow_forward
