Last year 68 year old Juana received her influenza vaccination and two days later she showed all the signs and symptoms of having contracted influenza.

(Please answer all parts, thank you!) 1) Mature red blood cells contain hemoglobin for transporting oxygen but contain little else. They lack a nucleus and most organelles. Are red blood cells more or less likely to be infected by a virus? a) More likely b) Less likely 2) How does SARS-COV-2 genetic material get replicated? a) Host cell DNA polymerase b) Host cell RNA polymerase c) RNA polymerase encoded for by viral genome and built in the host cell d) RNA polymerase encoded for by viral genome and originated from the virus 3) How does SARS-COV-2 proteins get built? a) The host cell's ribosome b) Ribosome encoded for by viral genome and built in host cell
you need a flu shot every year/season because (HA-haemoagglutinin; NA-neuroaminidase) A) the virus can change its HA and NA every year, so a new shot is needed to teach your immune system how to recognize the changed HA and NA B) flu virus gets rid of its HA and NA and replace them with completely new ones every year C) your immune system weakens after a year-so you have to get another shot to get the system strong enough to attack the virus D)antigen shift occurs every year
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.
When the patient's mother expresses concern about his sister being reinfected with chickenpox, what is the most appropriate response? A) Your concerns are valid, but his sister developed an active natural immunity to chickenpox because she has already been infected. B) Your concerns are valid and there is a high likelihood that his sister will become infected again. We should probably administer the vaccine. C) Your concerns are valid and there is no way to protect his sister from becoming reinfected except to keep her at least 15 feet from your son at all times. D) Your concerns are valid and if his sister is reinfected, her symptoms will be less severe than her initial chickenpox infection.
During a routine checkup, a 72-year-old patient is advised to receive an influenza vaccine injection. He questions this, saying, “I had one last year. Why do I need another one?” What is an appropriate response from the nurse? a )“The effectiveness of the vaccine wears off after 6 months.”b) “Each year a new vaccine is developed based on the flu strains that are likely to be in circulation.”c )“When you reach 65 years of age, you need boosters on an annual basis.”d) “Taking the flu vaccine each year allows you to build your immunity to a higher level each time.”
Which link in the chain of infection is the intervention described below meant to break? "N95 respirators reduce the wearer's exposure to airborne particles, from small particle aerosols to large droplets. N95 respirators are tight-fitting respirators that filter out at least 95% of particles in the air, including large and small particles." (https://www.cdc.gov/coronavirus/2019- ncov/hcp/respirator-use-faq.html) Portal of entry Means of transmission O Infectious agent Susceptible host

Your friend and you go to Central America for spring break where you have a great time (from what you can remember) except that you both get bitten by mosquitos constantly. Your poor friend comes down with malaria, has to take chloroquine, and is ill for weeks. You experience no health problems at all. You tell your friend, “Sickle-cell anemia runs in my family. That’s probably why I didn’t get malaria, too.” Your friend is not a super smart scientist like you so is utterly confused at your remark. Explain to him what you mean.
