\n“Flu season” is the time of year that flu viruses are most common. In the northern hemisphere, ideally, everyone should be vaccinated by the end of October. If a person is unable to get vaccinated until November or later, vaccination is still recommended because flu most commonly peaks in February and significant activity can continue into May.3

\nAnnual vaccination is the best way to protect against flu and reduce disease severity and complications. The CDC estimates that flu vaccination during the 2019-2020 flu season helped prevent an estimated 7.5 million illnesses, 3.7 million flu-related medical visits, and 105,000 flu-related hospitalizations.7 How effective the flu vaccination is can depend on several factors and vary from season to season.7
\nToday’s flu vaccines are made in chicken eggs, cell culture or through recombinant protein expression. Globally, egg-based manufacturing has been used for over 70 years and is the most common flu vaccine manufacturing process.8
