From: "Towards a universal flu vaccine" Each year, the flu vaccine includes antigens from two strains of Influenza A and two strains of Influenza B. These antigens are from the head of the H spikes - an area that sticks out from the virus and so, is very easy for human immune cells to detect. However, the problem with using the head of the H spike as an antigen is.. • The H spike head mutates very rapidly, so quickly changes to forms not recognized by human immune cells. O The H spike head is exposed on the surface of the virus for only a short period of time. Viruses quickly pull the H spikes back inside the virus, shielding them from human immune cells. O The H spike head is often too big for the human immune cells to attack. The H spike head is often too small for the human immune cells to bind to.

The Adaptive Immune Response Is a Specific Defense Against Infection In cystic fibrosis gene therapy, scientists propose the use of viral vectors to deliver normal genes to cells in the lungs. What immunological risks are involved in this procedure?
The Adaptive Immune Response Is a Specific Defense Against Infection Researchers have been having a difficult time developing a vaccine against a certain pathogenic virus as a result of the lack of a weakened strain. They turn to you because of your wide knowledge of recombinant DNA technology and the immune system. How could you vaccinate someone against the virus, using a cloned gene from the virus that encodes a cell-surface protein?
Several cell culture lines of epithelial cells, called “Cell Line A, B, or C,” are incubated with 104 infectious particles of influenza virus, and viral titers in the culture media are measured 2 days later. Looking at the results of this experiment, it is apparent that the three lines do not all show the same response to the virus. To investigate these differences, mixing experiments are performed, where cells from two different cell lines are mixed together at a 1:1 ratio before the Influenza infection. Based on the results shown in the figure below, propose an explanation for these data.
Please help me answer all parts of this question: (A)What strategy/type of vaccine would you pursue with the hopes of developing a vaccine to a new pandemic Coronavirus, attenuated virus vaccine or an inactivated virus vaccine? Compare how the two are produced, the limitations or advantages, and justify why you have picked one over the other. (B) Now, compare the above vaccines to mRNA vaccines. How are mRNA vaccines delivered? Are they better than the vaccines from part (A)?
a) What is “washing” in immunology? What types of interactions doeswashing interfere with? What molecules are used for effective“washing” in the immunology lab?b) Blocking is also a common feature of immunological assays. Why isblocking required?i. A student forgot to block their Western blot membrane beforeadding the secondary antibody. They continue and block themembrane after the secondary antibody step, assuming itdoesn’t matter which order the steps are completed in. Howwould this affect the results seen?ii. A student blocked their ELISA plate with 50 microlitres ofblocking buffer, although their coating, binding and detectionsteps were at 100 microlitres. How would this affect the resultsseen?
Despite our advancement in Science and Technology, thanks to the invention of the early scientists Robert Hooke and Antonie Philips van Leeuwenhoek that paved the way to the discovery of cells and the cure of many diseases, why is it that there are still many who are hesitant to have themselves immunized by COVID-19 vaccines?

Historically , vaccinations have prevented the spread of certain diseases chicken pox or meningitis. What type of externality takes place with th consumption of such vaccines. Explain with words and a graph.
Explain why you agree or disagree with each of thefollowing statements:a. We should not worry much about exposure totoxic chemicals because almost any chemical, at alarge enough dosage, can cause some harm.b. We should not worry much about exposureto toxic chemicals because, through geneticadaptation, we can develop immunities to suchchemicals.c. We should not worry much about exposureto toxic chemicals because we can use geneticengineering to reduce our susceptibility to theireffects.d. We should not worry about exposure to a chemical such as bisphenol A (BPA) because it has notbeen absolutely proven scientifically that BPA haskilled anyone.
An experiment was performed in mice. Wild-type bone marrow is used to reconstitute lethally irradiated Cr2-/- mice (wt®Cr2-/-), or vice versa (Cr2-/-®wt). As controls, Cr2-/- bone marrow is used to reconstitute Cr2-/- recipients (Cr2-/-®Cr2-/-), and wild-type bone marrow used to reconstitute wild-type recipients (wt®wt). These mice are then inoculated with the HSV-rd virus at 106 PFU, once at day 0 and then a second time at day 28, and the anti-HSV IgG responses are measured every 7 days, as shown in figure below. a) From the data shown above, on which cell type is the expression of the complement receptor most important for humoral immunity? b) For each of the cell types expressing the complement receptor encoded by Cr2, what is the explanation for their importance in humoral immunity to HSV inoculation?
Hybridoma technology allows one to generatemonoclonal antibodies to virtually any protein. Why isit, then, that genetically tagging proteins with epitopes issuch a commonly used technique, especially since an epi-tope tag has the potential to interfere with the function ofthe protein?
Regarding the production of monoclonal antibodies, it is CORRECT to state that: * A) Hybridomas are cells generated from the fusion of myeloma cells and cells from animals challenged with the antigen of interest that have the ability to produce antibodies and limited cell proliferation. B) All hybrid cells generated from the fusion of cells from the challenged animal and cells of the myeloma lineage will have the ability to produce antibodies reactive against the antigen of interest. C) The HAT selection medium contains aminopterin, which is an efficient inhibitor of the thymidine kinase metabolic pathway, thus eliminating myeloma cells that are not fused or fused with other cells of the same kind. D) The HAT selection medium contains hypoxanthine, which is an efficient inhibitor of the nucleotide synthesis salvage pathway, thus eliminating cells from the challenged animal that are not fused or fused with other identical cells. E) Hybridomas will produce antibodies with the…
