Some countries, such as the United States, Brazil and France, have agreed to make 10 percent of their national vaccine stockpile available to developing countries. Manufacturers have also donated about 150 million doses of vaccine.

that "We are just plain lucky ... This has been the case with the A/ H1N1 influenza pandemic... The virus did not mutate to a more lethal form. Cases of resistance to oseltamivir remained few and isolated. The vaccine closely matched circulating viruses and showed an excellent safety record," Chan said. "Emergency wards and intensive care units were often strained, few health systems were overwhelmed ... Schools closed, but borders remained open, and disruptions to travel and trade were far less severe than feared," she told delegates from the agency's 193 member states. "Had things gone wrong in any of these areas, we would have a very different agenda before us today," she added."

"Pandemics are unpredictable and prone to deliver surprises," Dr. Chan noted.
