Question 16-18 Which of the following is a reason why people need to get a new and different flu shot (vaccine) every year to remain protected from influenza? Influenza virus continuously evolves and as such evades immune recognition via antigenic drift. All vaccines need to be administered yearly to be effective. Scientists still have not found a good influenza vaccine, so they are trying out different vaccine types each year. Currently known influenza virus vaccines are not able to lead to immunological memory against any influenza virus strain. Question 17 Which of the following is FALSE in regards to adaptive immunity and the evolutionary arms race between parasites and pathogens? Microbes have a shorter generation time, so they will always win the pathogen-host arms race. After infection, lymphocyte replication and mutation rates are amplified. Vertebrates don't have to evolve as quickly as microbes at the population level. Rapid adaptive change can take place inside of one individual. Question 18 When you determine the Sequence of the MHC class I B gene, also called HLA-B, is it possible to find four different DNA sequences in two different persons? Through somatic recombination, HLA-B gene sequences will differ between people. There are many different HLA-B alleles circulating in the human population, and many people are heterozygous in this gene. There are many different splicing variants of HLA-B protein. This is actually not possible. The sequence in different individuals' HLA gene will always have the same DNA.
