China needs to manufacture pediatric HIV drugs for its tens of thousands of children suffering from the disease, an AIDS activist said, adding that the state was not giving enough help to the most vulnerable.
Antiretroviral drugs help prevent HIV replication and prolong the lives of people with the disease. But pediatric formulations are not widely produced as they are not regarded as commercially viable, because rich nations are very successful in preventing mother-to-child transmission of the virus.
Chinese companies began producing at least three generic ARVs in 2002, which sharply reduced the cost of caring for its citizens living with the disease, but does not manufacture dosages for children.
