3. You are a medical researcher working for Pfizer, which has developed a new meningococcal vaccine. Over a five year period, you tested the effectiveness of the vaccine to monkeys and then challenging the monkeys with meningitis bacteria. Without the vaccine, meningitis is fatal in 15% of the population (the 15% was determined from the monkeys who received a placebo- you can check this from the data). The following data results from the vaccine trials. Use the data from those monkey's receiving the vaccine (the middle column) to calculate a Chi-Square value and evaluate the null and experimental hypothesis. (Follow the steps as in problem #1 on a separate sheet of paper.) Number of Monkeys Surviving and Dying with and without the Meningitis vaccine Number of Monkeys Number of Monkeys Receiving Vaccine Receiving a Placebo 234 41 Monkeys who survived Monkeys who died 293 21

Do you think it is important in a clinical trial to have Moderna vaccine and placebo be similar? Why or why not?
1. A vaccine is a biological preparation that provides active acquired immunity to a particular infectious disease. Itstimulates your immune system to produce antibodies, exactly like it would if you were exposed to the disease. Unlike most medicines, which treat or cure diseases, vaccines prevent them. If you are given a mission of creating a vaccine, for what viral disease will it be? Why? 2. SARS-CoV 2 is the virus responsible for Covid-19. With the current situation in the Philippines, the number of positive Covid-19 cases are slowly declining but it’s not over yet. What do you think are the factors that contributed to the easy spread of this virus? 3. What can you do, as a student, in preventing the spread of Covid-19?
In the 1960s when polio vaccines were first administered in the United States the oral polio vaccine (OPV) was used. Explain why since 2000 the CDC now recommends the use of the injected polio vaccine (IPV) instead of the OPV.
12. Breaking the Chain of Transmission of Infection Messaging about how to contain Covid-19 and reduce the spread of SARS-CoV-2 has changed dramatically since the first appearance of the disease in January of this year. Misinformation is rampant and the general public is often confused about the best way to proceed. Using your knowledge as a biologist, write an essay that explains to your friends and family how disease is spread and how each step promoted by the Centers for Disease Control helps to break the chain of transmission and flatten the curve. Include how each of the following techniques a) breaks the chain of transmission of disease, especially COVID-19; and b) the consequences to an individual and to society at large of failing to implement the technique. Wash your hands often, for at least 20 seconds. Don’t touch your face. Clean and disinfect surfaces. Wear a face covering in public Stay at least 6 feet from others. Stay at home.
4. You seed a 10cm tissue culture plate with a 4x10^6 HeLa cells. HeLa fells have a doubling time of 24h. At 9am on Tuesday you wish to infect the cells with poliovirus at an MOI of 10. Your poliovirus stock is at a concentration of 4x10^7 pfu/ml. What volume of your poliovirus stock do you need to add to your plate of cells?
The Ro of Ebola has been estimated to be somewhere between 1.5 and 2. See graphic below. The number of people that one sick person will infect (on average) is called R₂. Here are the maximum R, values for a few viruses. more contagious R₂- Hepatitis C (2) Ebola (2) HIV (4) SARS (4) Mumps (10) Measles (18) **** What percentage of the population would have to be vaccinated to stop the spread of Ebola if it were to be introduced to a new continent? a. 33-50% O b. >99% C. 75-99% d. 66-75% e. <33%
A new vaccine is about to be launch anytime soon for HIV as prophylaxis using mRNA Moderna technology used in the development of Covid vaccine. If this will be successful , it will be a great breakthrough in the field of Pharmacology to help humanity fight this dreadful HIV virus. Give your thoughts about it.
Epidemiology 1. True or False: A screening test with 99% specificity and 99% sensitivity will necessarily have higher predictive values than a screening test with 50% specificity and 50% sensitivity. 2. True or False: If it's found that participants in a screening program were much less likely to die from the disease screened for after 20 years of follow-up compared to non-participants, then the screening program must have been the reason for the reduced mortality.

You are working in a pathology lab studying the virus Examinaria in mice. You collect the following information about two competing Examinaria strains, Aggressive and Mild: 1. Aggressive always out-competes Mild within a mouse for a payoff of 1. 2. Mild co-exists with Mild in a host for a payoff of 12. 3. Mild always loses to Aggressive for a payoff of 0. 4. Aggressive competing with Aggressive in a host leads to early death of the mouse and a payoff of only 14. Make a payoff matrix to solve this game. Based on the payoff matrix, is there one best Evolutionarily Stable Strategy (ESS) in this game? Yes, Aggressive is the ESS Yes, Mild is the ESS No, Mixed ESS
This is question is from my micro biology class. 2. Some RNA-dependent RNA-polymerase enzymes make a lot of mistakes. Why would this work to the advantage of a virus in terms of how effective a vaccine might be?
At a recent trip to the drug store, your pharmacist informs you that the flu vaccines are in. You fear the risk of getting the flu because you've had it before and it wasn't a pleasant experience. You proceed to get the vaccinated for the flu. Which of the following statements regarding your recent vaccination is true? O The vaccine you received protects you from every strain of the flu. O The vaccine you received protects you from the strain of bacteria which scientists believe will be common in the upcoming "flu season". O The vaccine you received protects you from the virus which scientists believe will be common in the upcoming "flu season". O The vaccine won't be effective because you've had the flu in the past and are immune to it.
