Both immunizations are injectable flu shots and protect against seasonal influenza. But, Fluzone® High-Dose contains four times the amount of antigen as the normal flu shot. The means seniors who receive the vaccine will have extra protection against the flu.

Two flu strains, peaking at different times At the start of the 2018-2019 flu season, the dominant circulating strain of virus was A(H1N1), and the flu vaccine was well matched to it. The more virulent strain, A(H3N2), was present at a low level until mid-January, when its incidence started sharply increasing.

The adjuvanted vaccine is still recommended for this age group in the 2019-20 season. It is not understood why flu vaccines do not work so well in older adults. However, this reinforces the importance of vaccinating children and healthcare workers, both of whom can help to stop the spread of flu to older adults.
