(a)
Interpretation: The validation of the given statement about viruses and vaccines has to be stated.
Concept introduction: The particle that has either RNA or DNA surrounded by a layer of protein is called virus. It cannot reproduce without the help of the host cell. The preparation that contains an inactive form of virus or bacterium is called vaccine.

- Antigenic drift refers to: A.The reassortment of genomic segments from different viruses B.Cytotoxic T cells identifying viral infected host cells C.The accumulation of mutations in the viral genome due to an error prone polymerase D.Antigen presenting cells failure to recognize the influenza virusarrow_forward( Notes ... 1. Describe what class of virus SARS-CoV-2 belongs to and why. 2. Compare the terms SARS- CoV-2 and COVID-19. 3. Briefly describe the life cycle of the virus in mammalian cells, paying special attention to the role of RNA. 4. Describe the mechanism by which the Pfizer and Moderna vaccines work, paying special attention to the central dogma of biology. 5. Discuss what you have learned about the vaccines' efficacy and safety. 6. Share any concerns you have either about the vaccine itself or about public perception and acceptance of the vaccine.arrow_forwardHow vaccines are prepared targetting Different types of viruses? Explain with examples. explain at your own wordsarrow_forward
- You have been hired by a major pharmaceutical company to develop a new vaccine toprevent COVID-19 infection and spread.a. What is a virus? Describe the viral life cycle. (3 marks)b. Describe the difference between an antiviral drug and a vaccine. (1 mark)c. What are three qualities you would prioritize when developing this new vaccine forCOVID-19 that you would want in the end-product? (6 marks) Note: Qualities should be overarching characteristics of the developed drug, not specifics regarding various molecular mechanisms of actionarrow_forwardDescribe how the antigenic components of current viral vaccines are produced and describe the process that may be followed to prepare a vaccine for the “novel Coronavirus”.arrow_forwardWhich of the following is true? a. conjugated vaccines are always those in which there is more than one vaccine anigen b. prevnar is conjugated vaccine c. conjugation involves ttaching a polysaccharide antigen to a carbohydrate carrier d. Conjugated vaccines tend to induce a poorer immune response than polysaccharide vaccine e. Pneumovax is a conjugated vaccine thank you!!!arrow_forward
- What are the techniques of prepared vaccines targetting Different types of viruses? explain at your own wordsarrow_forwardWhich of the following is a commonality between coxsackievirus A16 infection and a varicella zoster infection?Choose one: A. Both infections are caused by viruses in the herpes family. B. Each disease is usually mild and self-limiting in children but is more severe in adults. C. Both viruses can cause a spotted rash to appear on the palms of the hands and soles of the feet. D. There is a vaccine available for both viruses.arrow_forwardA live vaccine (aka attenuated vaccine) contains A.) antibodies. B.) a pathogen that does not cause an immune response. C.) a pathogen that causes mild, if any, symptoms. D.) a pathogen that does not contain recognizable epitopes.arrow_forward
- Suppose you are designing a study to determine whether a vaccine is effective. You recruit volunteers and then assign them into two groups. Which of the following is a better way to determine if the vaccine works in a wide variety of people? (a) Recruit people from a variety of backgrounds: different ethnicities, ages, sexes, etc... and then randomly form two groups. (b) Recruit people for the study who are very similar to one another, such as married nonsmoker female nurses in their forties who don't drink with no health problems and good incomes, then randomly form two groupsarrow_forwardThis is a hypothetical scenario. A recently emerged virus has been transmitting and mutating rapidly in humans throughout the world. If a vaccine that stops transmission of all current circulating variants of the virus in humans is utilized and herd immunity is achieved throughout the world, would this essentially stop 1) further transmission of the virus; 2) further mutation of the virus, respectively? Why/why not? Please answer the question succinctly and in bullet points!arrow_forwardExplain the role and importance of a viral vaccine.arrow_forward
