Without a new policy including vaccines, the government will continue to slaughter every flock with a bird flu infection to limit the spread of the disease. Those deaths have totaled over 166 million birds in the U.S. since 2022.

The existing vaccines don't match the current strain, and both the U.S. and E.U. have rules on imported birds that are vaccinated.

Manx Care is set to offer the flu vaccine to people who work with poultry following a reported increase in avian flu in the UK. The health body is set to invite those who work with or handle poultry, but have not yet had a seasonal flu vaccine for winter, to book a vaccination before the end of this month.
