Scientist say developing an HIV vaccine has been as challenging as developing one for malaria.
Rick King from International AIDS Vaccine Iniatiative says due to the complexity and diversity of
the HI Virus it's been impossible to design a broad vaccine that will match up to HIV. 

It's taken over 20 years for researchers and scientist to try to develop an HIV vaccine.
King was speaking to journalists ahead of the AIDS Vaccine Conference in Bangkok in Thailand.
It's expected that details of tests following the Thai Vaccine Trial will be made public today at the conference.
King says complex vaccine regimens are required to tackle HIV head on.

People living with HIV in Thailand are subjected to compulsory HIV tests by potential employers and if
found to be positive they do not get the job

People living with HIV in Thailand are subjected to compulsory HIV tests by potential employers and if found
to be positive they do not get the job. This was revealed by Jintanat Anan-wora-nich, the Deputy Director in
Scientific Affairs at the Thai Red Cross AIDS Research Centre. She was addressing journalists ahead of the AIDS
Vaccine Conference which will begin in the Thai capital, Bangkok, today.

Anan-wora-nich says the practice has been going on for years but there is very little government can do to stop it.
It's not a choice, they test everyone for HIV before accepting them into the workplace and after that some companies
check every year. The companies refuse to employ people who are HIV positive even though this is illegal.
It is illegal to discriminate against people based on their HIV status but this is what is common.
It has been difficult to challenge this practise because people who are affected by the virus don't want to come
out and complain because they don't want to show that they have HIV.
