- Research on HIV vaccines is progressing, but success to date has been limited to vaccines that are of limited effectiveness against a few strains of the HIV virus. However, flu vaccines are similar in their limitations. Why are ‘limited effectiveness flu vaccines released, but not HIV vaccines? Answer:Vaccines have effectively prevented many viral diseases. Attempts over many years to develop an effective vaccine against HIV disease and AIDS, however, have so far met with little success. Why is this so?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?
- 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 groupsDespite 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 wordsThe 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?
- As conversations about vaccines goes on around the various social media platforms,why would scientists want to study these conversations and what might they may be able to learn from these social networks?This 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!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... O The H spike head. O H spike neck O N spike O Viral envelope
- It used to be that our only method of creating vaccines was to use dead or weakened pathogens. That is no longer the case - what are some newer options that are available to researchers?Why might an HIV/AIDS vaccine actually give some people a false sense of security?Effective vaccines have been developed against diseases such as hepatitis B,smallpox, polio, tetanus, influenza, and the measles. But what about AIDS?
