Seasonal Influenza Vaccine & Total Doses Distributed

This figure and table reflects the cumulative weekly total number of seasonal influenza vaccine doses distributed in the US as reported to CDC by influenza vaccine manufacturers and selected distributors. Updated distribution numbers will be posted when CDC receives them. In most cases, these updates will be posted on Fridays. Please check this page frequently for the most up-to-date information regarding flu vaccine distribution for the 2014-2015 season.

As of mid-October, seven influenza vaccine manufacturers are projecting that as many as 151 million to 156 million doses of influenza vaccine will be available for use in the United States during the 2014-2015 influenza season.

During September, some manufacturers, including those who develop flu vaccines approved for children in the United States, reported delays in shipments that were originally anticipated for early fall. Despite these early season shipping delays, however, approximately 85% of the total doses projected for the season were distributed by the end of October. Flu vaccine doses have continued to be distributed since the end of October.
