What to know
Flu vaccines are produced by private manufacturers, so supply depends on manufacturers. For the 2020-2021 season, manufacturers projected they would provide as many as 194 to 198 million doses of flu vaccine for the U.S. market.
Manufacturers distributed flu vaccines with no significant delays reported. Because of the record number of doses produced during the 2020-2021 season, production and distribution occurred over a longer period.
