Brad receives a viral vector coronavirus vaccine that uses a specific adenovirus and your immune system mounts a strong immune response. Luis receives an RNA coronavirus vaccine and also has a strong immune response. One year later a new coronavirus variant emerges and neither of the original vaccines protects people from this new variant. A new viral vector vaccine is developed to the variant using the same adenovirus as before. In clinical trials, it is found that the new vaccine protects people that originally received the RNA coronavirus vaccine that Luis had but does not protect people that originally received the viral vector coronavirus vaccine that Brad had. Can you think of an explanation for why the new vaccine didn't protect Brad but did protect Luis?

A report from the U.S. National Academy of Sciencesand the National Academy of Medicine is recommendingthat germ-line therapy trials only be consideredfor serious conditions for which there is no reasonablealternative treatment option, and where both the risk–benefit options and broad oversight are available. Is thiskind of procedure ethical?

It is said that a vaccine does not prevent infection; rather, it primes theimmune system to undergo an immediate response to prevent aninfection from spreading. Explain what is meant by this statement, and outline what is happening at the cellular/molecular level from the timeof vaccination until subsequent contact with the infectious agentactually occurs.
Why are vaccines made ofthe own disease agent or offragments of it?
Julia has a new baby and has received the vaccination schedule from the GP whichincludes the MMR. Julia is nervous about giving her new infant the vaccination as it makes use ofattenuated forms of the three viruses and asks the GP whether it is essential. Explain to Julia whythe MMR is important and evaluate the effectiveness of the vaccine.
Antigenic shifts in influenza viruses are represented by dra-matic changes in the viral antigens. It is likely they arise fromrare events in which:(a) Two different influenza viruses infect a cell at the sametime(b) Two separate viruses undergo lysogenic conversion(c) Two viruses conjugate(d) Mutations accumulate(e) All of the above
e) Bats have been implicated as the source of many viruses against which humans have a difficult time mounting an effective immune response. Interestingly, flight plays an important role. i) Describe and explain i) the role that flight plays in creating these kinds of viruses, ii) how the viruses cross over into humans, and iii) why our immune response has a more difficult time mounting an effective response against them

Let’s say there are two closely related viruses, let’s call them Guernsey virus and Micro virus. These two viruses only infect epithelial cells. Their surface antigens are sufficiently similar that there are a number of shared epitopes between the two viruses. Choose one of the following: A) If you get infected and successfully recover from one virus, it’s quite possible that you’ll have neutralizing antibodies against the other. B) If you get infected and successfully recover from one virus, you’ll still be susceptible to the other one because the antigens aren’t exactly the same. C) If you get infected and successfully recover from one virus, it’s likely that getting infected with the other virus will be worse because of the common phenomena of antibody-dependent enhancement. D) Not enough information has been given.
