Lawyers for the South African government yesterday in Constitutional Court argued that universal access to nevirapine is unnecessary because on average, pregnant women transmit the virus to their infants only 30% of the time, the South African Press Association reports. "You are giving a drug to 70% who do not need it. And you are introducing a drug of which you do not know the long-term effects," government attorney Marumo Moerane told the court during the first day of testimony in the government's appeal of a lower court order that it make the drug available to all HIV-positive pregnant women through the public health system.
