There is mounting evidence that vaccine protection diminishes over the course of a single season since getting the flu shot, meaning an individual vaccinated in early September may be more vulnerable than someone vaccinated in late October when flu season hits.

A recent study published in Clinical Infectious Diseases found that an eight-week delay in vaccination might prevent about nine flu cases for every 1000 persons vaccinated during an average season. These findings backup previous research, including a 2017 study by CDC scientists that found vaccine effectiveness for strains of H1N1 declined up to 11 percent each month after administration.
