An HIV Vaccine?!

 
I know that this is not directly related to vaccinations and autism, but I thought this article was very interesting. It discusses how they now trying to develop a vaccine for HIV. Currently, 25 million people are infected with HIV. This year alone, 5 million people were diagnosed, and that number has been on the rise. This article seemed so interesting to me because we all know that HIV is a sexually transmitted disease, and for some reason, I never thought that scientists and researchers would like to find a way to prevent it. I only believed that they were on a mission to cure it, but like many other diseases, HIV also takes many lives and can be seen as an epidemic.
To make a successful vaccination against HIV, there are a few factors that need to be involved. They include mucosal immunity, antibodies present in your cells, cellular immune responses, and the overall response and reactivity of the immune system. Because live pathogens are typically better in vaccines, it is very difficult to handle HIV. When tested on animals, AIDS was developed, which is not what we would want.
I think it would be interesting to see if the HIV vaccine could be successful. Like every other disease that we make a vaccine for, it is always extremely beneficial. However, I am intrigued in seeing if curing the disease will lead to other side effects or coincidences like in the vaccine and autism battle today.
