Document Summary
Independent study outcomes: the general mechanisms by which vaccines protect against diseases. Create a cache of weapons that you can deploy when needed. Modify a pathogen, to help you fend off something you don"t have natural immunity to: why developing a vaccine against hiv is relatively challenging, compared to other diseases. Increased genetic variation, mutates furiously, hides itself in your genome: why people are encouraged to get a flu vaccine each year (as opposed to one time only). Vaccine protects you against a few of the most common predicted strands each year. Lecture outcomes: general global distribution of hiv infections. Almost 60% of hiv infected individuals live in south sub-saharan. Africa: general temporal trends in hiv infection rates. Number of people living with hiv continue to increase. Death is beginning to plateau due to anti-viral therapies: factors that explain why no cure or universal vaccine has been developed for hiv/aids.
