The U.S. government (NIH) refuses any funding of an AIDS vaccine which utilizes the viral RNA itself under the false pretext that the vaccine might infect people.
But if richer nations were willing to donate anti-viral drugs and guarantee a supply of any vaccine that becomes available, poorer nations might be willing to reach agreements over surveillance and preparedness.
The first study - involving more than 68, 000 infants aged six to 12 weeks - found a vaccine called Rotateq being developed by the pharmaceutical company Merck could safely prevent 98% of severe cases of viral diarrhoea and vomiting.
