Viruses and Vaccines
Viruses are very small, but they can cause some of the most serious diseases on Earth. These diseases can impact human health as well as threaten the food supply by impacting livestock and crops. In this Discussion Board, you will see the role of science in creating vaccines to prevent some of the most serious viral infections facing mankind. Select 1 of the following vaccines to be the subject of your Discussion Board this week:
• Influenza vaccine
• Smallpox vaccine
• Polio vaccine
• Tetanus vaccine
• Chickenpox vaccine
Write 400–500 words that respond to the following questions with your research. This will be the foundation for future discussions by your classmates. Be substantive and clear, and use examples to reinforce your ideas.
• Provide a brief history of the vaccine that you selected. How was it invented and how is it produced?
• How often must a person receive your vaccine to be protected against the disease?
• What role do you think vaccines play in preventing the spread of disease?
