Start of an HIV vaccine:

This is a really exciting article to read:

"A vaccine to prevent HIV infection, the virus that leads to AIDS, has shown modest results for the first time, researchers have found, raising hopes that a disease that kills millions every year may someday be beaten."

The vaccine trial took place in Thailand and included more than 16,000 HIV negative participants. Half were given a placebo and the other half were given the real vaccine. After a 6-month period:

"Fifty-one people in the vaccine group eventually contracted HIV, compared with 74 in the placebo group."

The HIV booster was shown to possibly reduce the risk of HIV contraction by 31 %

This is one of the most important articles I have come across this year. It will have so much potential to prevent such a huge problem the world faces.
