Assignment Prompt & Instructions

The World Health Organization (WHO) defines vaccine hesitancy as the, “Delay in acceptance or refusal of vaccines despite availability of vaccination services.” It has been reported in more than 90% of countries in the world.” In many areas, immunization for measles, a vaccine-preventable disease that was largely eliminated following widespread use of the measles-mumps-rubella (MMR) vaccine, has decreased to less than the threshold set by WHO as that required for herd immunity.

Based on the current public health epidemic of vaccine hesitancy, please respond to the following prompts:

1.  Are vaccinations a type of active or passive immunity? Why so? (3 points)

Vaccinations are a type of **active immunity** because they stimulate the immune system to produce a response, including memory cells, which provide long-term protection against a specific pathogen.

2.  The MMR vaccine is classified as what type of vaccination? What makes this vaccine unique compared to other categories of vaccines? (2 points)

The MMR vaccine is a live attenuated vaccine, meaning it contains weakened forms of the measles, mumps, and rubella viruses. This type of vaccine produces a strong and long-lasting immune response compared to inactivated vaccines.

3.  What is the body’s physiological response after receiving an MMR vaccine? Please give a minimum of 4-5 sentences to fully describe the immune response. (5 points)

4.  The WHO mentioned that in some parts of the world, we have decreased to less than the threshold set by WHO as that required for herd immunity. Using your best research skills, please find the threshold (percentage) needed for herd immunity formeasles, and also explain why it’s important to stay above this threshold. Please be sure to include the website/resource you used to find the threshold percentage for measles. Why do different pathogens have different thresholds? (5 points)

The patient is a 3-year-old male who presented with a 4-day history of fevers. He became acutely ill and vomited during lunch. Over the next 4 days he developed fevers as high as 104 degrees F that were controlled by Tylenol. He also developed a cough, runny nose, and conjunctivitis. He was very sleepy. He also displayed slight swelling in his feet. Other pertinent info: He attended daycare which his parents reported as being “full of sick children” and has a 1-year-old sibling who just started experiencing some wheezing and a productive cough. His respiratory examination was normal. findings from his bloodwork were all normal, but he tested positive for RSV and Influenza A.

1.  Where did this child likely become infected with both RSV and Influenza A? (1 point)

2.  What is the usual outcome of the flu in a young child? What patient populations are particularly prone to infections with this agent? (5 points)

3.  Briefly describe the vaccine available for the flu. Is this vaccine required? (2 points)

4.  Considering the vaccine described above, give 2 reasons why some people refuse to give their children vaccination for preventable illnesses? (3 points)

5.  True or False: Herd immunity is important in protecting those individuals in the population who cannot be vaccinated due to other health concerns. (1 Point)

6.  Describe the treatment available for each of these viruses. (3 points).

A 24-year-old woman reports to her health care professional with complaints of a yellow discoloration of her skin, loss of appetite, and a feeling of upper gastric discomfort. She denies use of intravenous drugs and has not received blood products. She cannot recall eating uncooked shellfish or drinking water that might have been contaminated. She has a daughter who attends daycare. What tests can be done to confirm a diagnosis of Hepatitis A? (3 points)

1.  What is the most common mode of transmission for HepA? (1 point)

2.  It is suggested that the source might be through the day care center that her daughter attends. Please explain. (3 points)

3.  What methods could be used to protect other family members from getting the disease? (4 points)

4.  Describe the geographical distribution of HepA along with some prevention and intervention methods that can be incorporated in a) low/middle income countries and b) high income countries. (4 points)

A mid-sized city in the U.S. is experiencing a surge in opioid use, leading to increased rates of hepatitis B and HIV. In response, the city health department is considering implementing a safety needle exchange program to reduce harm among intravenous drug users. However, the proposal has sparked a heated public debate. Some stakeholders argue that the program will promote public health and reduce infectious disease transmission, while others worry about ethical concerns, legal issues, financial costs, and potential unintended consequences.

Based on this case, answer the following questions:

1.  What are the main public health benefits of a safety needle exchange program? Provide at least two supporting statistics or real-world examples. (3 points)

2.  What are the main concerns raised by opponents of safety needle exchange programs? Provide at least two supporting arguments. (3 points)

3.  What role do harm reduction strategies play in public health, and how do they apply to needle exchange programs? (3 points)

4.  If you were a public health policy advisor, how would you address concerns from community members who oppose the program? (3 points)

5.  What are some possible compromise solutions that could balance the concerns of both supporters and opponents? (3 points)
