Adam Castillejo from London has now been cured from HIV for over 30 months, making him the second patient cured from the virus. In 2011 Timothy Brown was declared cured after three and a half years of not having the virus following similar treatment. Both men received stem-cell treatment transplants that worked by replacing the patient’s immune cells with the HIV-resistant donor ones. However, this therapy was used to primarily target the cancer the patients had, not the HIV, meaning the treatment won’t be available to HIV patients any time soon. Current HIV drugs are effective in allowing the patient to still live a healthy and long life as if they didn’t have the virus.
