Scientists at the University of Nebraska-Lincoln have engineered an on/off switch on to a weakened strain of HIV. A weakened virus is generally preferred by scientists because it has the potential to produce a stronger and longer-lasting immunity in patients. Researchers have said humanity is "one step closer" to a vaccine for HIV after the latest breakthrough. However, weakened viruses – as opposed to deactivated viruses – still possess the ability to replicate and spread disease instead of an immunity. This would allow them to spread the virus throughout someone's body, before deactivating the strain after it has immunised the host.
Criminal law out of step on HIV
The law has become more draconian even as HIV has become more manageable and as transmission risks decrease. People living with HIV who have access to sustained treatment have more or less the same life expectancy as those who are HIV-negative. Knowledge of prevention strategies is also better than ever, and it is much harder to transmit HIV than generally supposed. For more than seven years, the Ontario Working Group on Criminal Law and HIV Exposure has attempted to engage in meaningful dialogue with the provincial Ministry of the Attorney General in order to ensure that allegations of HIV non-disclosure are handled by Crown prosecutors in a manner that is consistent with current science, human rights principles and the public health response to HIV. While there remains no cure for HIV, available medications are effective at managing the virus.collected by :Lucy William
