People over 65 will be able to get the flu shot starting October 26. This year, they will be able to benefit from a “high dose” vaccine, Efluelda, which prevents 24% more flu.

Its effectiveness was evaluated there in 32,000 people aged 65 and over during two influenza seasons. Compared to the standard dose vaccine, the high dose vaccine prevented 24.2% more cases of influenza.
This HD vaccine is available for the 2021 vaccination campaign which will start on October 26. The vaccine is 100% reimbursable by Health Insurance for all so-called “at-risk” people who have received a care voucher.
