Vhich of the following enables almost all cells of the body to be recognized by an individual's immune system as "self"? O The presence of class II MHC molecules on cell surfaces O The presence of ABO antigenic markers on cell surfaces O The presence of Ig D molecules on cell surfaces O The presence of class I MHC molecules on cell surfaces QUESTION 2 In a vaccine preparation, the term "attenuated" means that the agent does NOT replicate. O True O False QUESTION 3 Opsonizing protein must attached be against O protein O phagocytic O internal O surface components if they are to effectively stimulate phagocytosis.

From: "Towards a universal flu vaccine" Researchers are trying to create a universal influenza vaccine - one that can confer immunity to all, or nearly all, strains of influenza virus. The universal vaccine will target a stable antigen that is present on all influenza viruses that does not readily mutate to different forms. The target researchers are focusing on as a universal stable antigen is on the... The H spike head. O H spike neck ON spike O Viral envelope

Which of the four major structural proteins, namely spike (S), membrane (M), and envelope (E), is the main target for the coronavirus vaccines? What factors influence the durability of vaccines? How frequently do you think a coronavirus vaccine may need to be administered?

Why is creating a vaccine to SARS CoV2 challenging?  What is herd immunity and how can a vaccine help us to achieve it?

Which of the following apply to MHCII molecules? Found on the surface of all human cellis Found on the surface of red blood cells Function to present (display) antigen for Tc cells None of the above apply O Found on the surface of antigen presenting cells (APCS) OFunction to present (display) antigen for B cells

Why is it important to characterize the type of immune response elicited by a vaccine during vaccine development?

A 5 year old patient is presenting in a clinic. She has received a C1 complement deficiency diagnosis. What could have lead the diagnostic team to conclude this? Select one: a. B and T cells were not properly responding and functioning b. immune system has rejected her tissues and organs C. excess of phagocytic cells d. immune system has developed allergic reactions to some of her tissues immune system is correctly distinguishes pathogen-associated molecular patterns (PAMPS) e.

T-cell receptor diversity is controlled by O b. O c. 1 O d. e. DNA recombination during mitosis in T-cells DNA recombination during prophase of meiosis II DNA recombination during prophase of meiosis l proteasomal degradation of viral proteins proteasomal degradation of host proteins

that causes the rapid reproduction of a specific ( Select] [ Select ] Antigenic cell B cell I cell Macrophage Eosinophil Vaccines work by stimulating a(n) [Select ] that produces an antibody that is specific for the antigen in the vaccine. This creates a pool of memory cells that will be available if the person is ever infect nicrobe.

The universal vaccine will target a stable antigen that is present on all influenza viruses that does not readily mutate to different forms. The target researchers are focusing on as a universal stable antigen is on the... The H spike head. O H spike neck N spike O Viral envelope
