- 1."What protein structural features are involved in the antigenic nature of epitopes? 2.What steps occur in the immune response following the primary infection of a vertebrate by a virus? 3.Assume you know that for a particular non‐enveloped virus, gene A codes for a transcriptional activator, gene B for an origin binding protein, and gene C for a capsid protein. Following a normal infection in an animal, what would most likely generate a neutralizing antibody?"Efforts to produce an HIV vaccine have met with limited success. What aspects of the virus and its replicative strategy make it difficult to produce a vaccine against HIV? What other kind of virus might be similarly different to vaccinate against? What similarities and differences exist between the two types of virus that account for the differences in vaccine production?2. Does SARS-CoV-2 conform to the central dogma of molecular biology that was coined by Francis Crick? 3. Retroviruses, like the HIV, contain an enzyme called reverse transcriptase. Explain the flow of genetic information in HIV. 4. COVID-19 vaccines such as Moderna (MRNA-1273) and Pfizer (BNT16262) make use of mRNA that produces SARS-CoV-2 spike protein. Would the effectiveness of these vaccines be affected by the emerging SARS-CoV-2 variants with mutated spike protein?
- The world has been greatly affected by the pandemic caused by COVID-19. Countries all over the world are in constant roll-out for vaccines to be administered to its people. Between vaccines and people, what is limited and what is in excess? How can we lessen the number of excess?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? Please answer with 500 wordsAccording to the article which was written before the COVID-19 vaccine was created, when do people turn to magic? How can this tendency, which happens across cultures and throughout history, contribute to the current spread of the novel coronavirus and its variants?
- Viruses can easily mutate exchange genetic material, mechanisms referred to as antigenic drift and antigenic shift. These changes allow the virus to evade the immune system defenses. Match each term with the correct definition Antigenic drift [ Choose ] [Choose ] Different strains of a virus or strain of different viruses, combine and form a new strain that now has a mixture of the surface antigens Antigenic shift The virus changes genetically by accumulating mutations within the genes that code for antibody-binding sites1. A vaccine is a biological preparation that provides active acquired immunity to a particular infectious disease. Itstimulates your immune system to produce antibodies, exactly like it would if you were exposed to the disease. Unlike most medicines, which treat or cure diseases, vaccines prevent them. If you are given a mission of creating a vaccine, for what viral disease will it be? Why? 2. SARS-CoV 2 is the virus responsible for Covid-19. With the current situation in the Philippines, the number of positive Covid-19 cases are slowly declining but it’s not over yet. What do you think are the factors that contributed to the easy spread of this virus? 3. What can you do, as a student, in preventing the spread of Covid-19?A new vaccine is about to be launch anytime soon for HIV as prophylaxis using mRNA Moderna technology used in the development of Covid vaccine. If this will be successful , it will be a great breakthrough in the field of Pharmacology to help humanity fight this dreadful HIV virus. Give your thoughts about it.
- Choose all the true statements regarding coronavirus proteins. Vaccine preventable diseases include COVID-19. For coronaviruses, it is more likely to find evolving mutations in the portion of the spike protein than the nucleocapsid protein. Mutations in the genetic code for the spike protein will produce 3D changes that are more likely to affect vaccine efficacy than changes to the nucleocapsid protein code. The nucleocapsid protein interacts with viral nucleic acid specifically whereas the spike protein interacts with the host protein non-specifically.1) a. Why does the immunity offered by COvid vaccines last only for about 2-3 months maximum (compared to other vaccines)? b. Are vaccines the only or the best treatment for Covid? Do the type of vaccines matter? WIll it help for us (public) to learn in an easily accessible manner the side effects (and the frequency of occurrence) of the Covid vaccine? c. Should it be mandatory for all members of the population to take vaccines, assuming that it is readily available? d. Should there be clinical trails performed by agents (institutions) outside the very drug companies that manufacture them? Currently that option is not is not available readily.D) RNA polymerase 29. In lecture, we discussed some of the new platforms for COVID-19 vaccines. Adenovirus-vector vaccines and mRNA vaccines both involve the introduction of pieces of DNA or RNA, respectively. In both cases, the objective is to ... A) enable the human body to produce the SARS-coV-2 genome. B) enable the human body to produce the SARS-coV-2 spike protein. C) inhibit viral polymerase. D) inhibit neuraminidase. E) inhibit reverse transcriptase.
