How does one interpret the susceptibility results from figure 3? What characteristics does this organism possess which account for these results?

What are the immune responses to viral infections? What is the difference between epidemic and pandemic? The “Spanish Flu” in 1918 was caused by the H1N1 influenza virus. What do the “H” and “N” stand for?

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.

The vaccine for Haemophilus influenzae type b is called a conjugate vaccine. It is composed of the tetanus toxoid protein conjugated to the capsular polysaccharide of the H. influenzae type b bacteria. When used to vaccinate infants, the antibody response generated by this vaccine would include 0 0 0 0 antibodies that bind only to the protein-polysaccharide conjugate in the vaccine. antibodies to the tetanus toxoid only. antibodies to the bacterial polysaccharide and the tetanus toxoid. antibodies to the bacterial polysaccharide only.

Two newly developed vaccine candidates (A and B) are tested in mice for their ability to elicit high concentrations of anti-meningococcal antibodies that would provide mucosal as well as bloodstream protection. Also, the ideal candidate vaccine should also provide long-lasting immunity to the infection.  The figure below shows the responses to a primary, followed by a secondary immunization to each of the two candidate vaccines. a) Which candidate vaccine elicits the preferred response? What are the three aspects of the preferred response that make it the candidate vaccine of choice?  b) What is the likely composition of each vaccine and what evidence from the information above are used to lead to your conclusions? c) To confirm the choice of the preferred candidate vaccine, what type of additional information from the vaccine trials in mice shown above would support this conclusion? Name two additional features of the secondary antibody response to each candidate vaccine that could be…

Madison Tavistock, a healthy 2-year-old living in Cincinnati, had attended the Wee Folks Daycare Facility for a year. Her parents joined an anti-vaccination group when she was 9 months old, 3 months before the recommended immunization schedule for the MMR vaccine, but after Madison had already been vaccinated with DTP. They strongly believe that the unsubstantiated risk of autism reported for MMR vaccination outweighs the benefits, and consequently have opted not to have their daughter immunized. The best explanation for why Madison has not contracted measles even though she has regular contact with other children in a large city is that _____. a. Madison is tolerant to measles antigens. b. The measles virus may have infected Madison but is dormant. c. The DTP vaccine provides cross-protective immunity against measles. d. The other children in the daycare center have been vaccinated and she has herd immunity. e. The attenuated measles virus in the MMR vaccine received by…

Each year the Centers for Disease Control and Prevention publish a schedule of recommended vaccinations for infants, children, adolescents, and adults. Parents may refuse recommended vaccinations for their infant, child, or adolescent based on religious or philosophical beliefs or fears regarding the safety of vaccines. What ethical principles need to be considered when dealing with patients and their families who refuse recommended vaccines? How would you approach a parent who refuses the recommended vaccines for their 2-month old infant due to the fear that vaccines can cause autism?

Why is creating a vaccine to SARS CoV2 challenging?  What is herd immunity and how can a vaccine help us to achieve it?

A pathogenesis function f(t)t(t-21)(t + 1) is used to model the development of the disease, where t is measured in days and f(t) represents the number of infected cells per mL of plasma. What is the peak infection time for this virus? (Round your answer to one decimal place.) t= Need Help? X days Read It

All of the following are true concerning the Alere HIV test except: a)this test can detect infection 10 days post exposure b)the presence of three lines on the test indicates a positive reaction for anitgen and antibody against HIV c)unlike Oraquick the test is run with blood sample only and not oral fluid d)the presence of a single line indicates that a person has antibodies but no antigen for HIV  e)this is a test that is considered both a direct and indirect test for HIV diagnosis
