Merck HIV Vaccine

Merck’s HIV vaccine was canceled because it didn’t work. At least, that’s what the pharmaceutical gian told us. Now, it seems that the vaccine may actually make some people more susceptible to the virus. Merck had boasted that the vaccine was the greatest hope yet in preventing HIV before it was canceled in September. The vaccine couldn’t give a patient the HIV virus. However, it could render one’s immune system more vulnerable to the deadly virus.
