WASHINGTON (Reuters) - The first U.S. roll-out of vaccines against the new swine flu virus will be 3.4 million doses of MedImmune's nose spray, the Centers for Disease Control and Prevention said on Friday.
The CDC's Dr Jay Butler said the vaccines would be distributed the first week of October.
"Initially we anticipate that 3.4 million doses of vaccine will be available," Butler told a telephone briefing.
"We anticipate being able to start receiving orders for the vaccine by early October," Butler added. The U.S. government is providing the H1N1 vaccine for free to about 90,000 distributors, including doctor's offices, retail chains and state health departments.
"We estimate that the amount of vaccine that will be available will increase through October," Butler said, adding that eventually delivery would rise to about 20 million doses a week.
