There are many opinions on the need and/or importance of vaccines in preventing the spread of disease. Our children are required to get vaccinations before entering school, and health care workers must have them when working in environments where they can encounter bloodborne pathogens. Human immunodeficiency virus ( HIV) and Hepatitis C ( HCV) are the two more prominent concerns for medical staff and for the worldwide community. Despite precautions, these diseases are both considered emerging infections. Neither of them have had vaccines developed that are effective at preventing the contraction of the disease. For your initial post, research the two diseases HIV and HCV. Based on your research, discuss whether you think that a vaccine will be developed for either of these diseases within the next ten years. Why or why not? For your reply post, expand your peer’s ideas by sharing examples from your own experience or readings, suggesting outside resources to support the topic, and/or asking furthering questions to dig deeper into the topic.

(2 points) what is a biopsy? 3. how was a biopsy performed on harold? 4. differentiate between gastric and duodenal ulcers by location. 5. what role does h. pylori play in the formation of peptic ulcers? 6. define occult and frank blood.
