WASHINGTON, Aug. 6 - Government scientists say they have successfully tested in people a vaccine that they believe can protect against the strain of avian influenza that is spreading in birds through Asia and Russia.
Health officials have been racing to develop a vaccine because they worry that if that strain mutated and combined with a human influenza virus to create a new virus, it could spread rapidly through the world. (The vaccine cannot lead to such a situation because it is made from killed virus.)
The director of the National Institute of Allergy and Infectious Diseases, Dr. Anthony S. Fauci, said that although the vaccine that had undergone preliminary tests could be used on an emergency basis if a pandemic developed, it would still be several months before that vaccine was tested further and, if licensed, offered to the public.
But he cautioned: "We don't have all the vaccine we need to meet the possible demand. The critical issue now is, can we make enough vaccine, given the well-known inability of the vaccine industry to make enough vaccine?"
