Active vs Passive vaccination, which is false: A. Passive vaccination: involves infusion of another person's activated B cells resulting in immediately available antibodies. B. Active immunity provides long term protection C. Passive immunity produces short term protection from the specific virus D. Attentuated live vaccines, subunit vaccines including empty capsids, and recombinate vaccines are example of active vaccination.

Explain why each choice (a-d) is correct or incorrect. A vaccine is effective because a. The vaccine contains the antibodies necessary to fight infection. b. The vaccine contains the lymphocytes necessary to fight infection. c. The secondary response of the adaptive immunity is faster and more efficient than the primary response. d. B lymphocytes are unable to mount an immune response the first time they are exposed to a new pathogen.
Antibodies 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.
Which of the following should be the same inidentical twins?(A) the set of antibodies produced(B) the set of MHC molecules produced(C) the set of T cell antigen receptors produced(D) the set of immune cells eliminated as self-reactive
The four characteristics of adaptive immunity include all of the following except a. activation by a specific antigen. b. memory. c. production of clones of cells that have the same TCR or BCR. d. effective against a wide array of pathogens.
Which of the following best describes the impacts of antigenic variation? Mark all that apply. A. requires clonal selection of B cells B. causes a primary immune response C. involves T-independent immune responses D. memory cells are stimulated by the antigen variants
Which one of the following most correctly describes vaccines containing live, attenuated pathogens? A.They are administered by injection. B.They provide little cell-mediated immunity. C.There is no possibility for reversion to pathogenic form. D.Pathogen does not multiply in human hosts E.They provide extended, sometimes life-long immunity.
Which of the following statement(s) about DNA vaccines is(are) NOT true? Check all that apply. A.) DNA vaccines are an example of "ex vivo" vaccination; cells are removed from the body, transfected with DNA expressing the antigen(s) of interest, and then the cells are returned to the body. B.) DNA vaccines can be used to immunize with multiple different antigens. C.) DNA vaccines only stimulate B cell responses. D.) DNA vaccines only stimulate T cell responses. DNA vaccines alone often result in poor immunogenicity
Compare and contrast live attenuated vaccines, inactivatedvaccines, and toxoids. Which of these has the greatest potentialto cause active disease in the recipient? Which typically providesthe longest-lasting immunity?
Which of the following statement regarding the whole-pathogen vaccine is/are correct (B) Live attenuated whole-pathogen vaccines are more effective to elicit a robust immune response, and often a single dose is sufficient. A and B are correct (A) Inactivated whole-pathogen vaccines are usually less immunogenic and often require booster doses/s A and C are correct (C) Inactivated whole-pathogen vaccines never cause disease but live attenuated vaccines always cause a mild disease.
It is said that a vaccine does not prevent infection; rather, it primes theimmune system to undergo an immediate response to prevent aninfection from spreading. Explain what is meant by this statement, and outline what is happening at the cellular/molecular level from the timeof vaccination until subsequent contact with the infectious agentactually occurs.
True or false a. The immune system normally produces "self-antibodies" to recognize self cells b. Vaccines work by showing the immune system a "preview" of a virus or other pathogen. c. Viruses cannot evolve because they are not alive. d. We can stop vaccinating for a disease once no more cases are being reported. Choose one of the FALSE statements from the previous question and explain why it is false.
