This week is National Influenza Vaccination Week in the U.S. Established by the Center for Disease Control and Prevention (CDC) in 2005, this week highlights the importance of continuing flu vaccination through the holidays and beyond. Vaccines against the flu are the best defense against the virus and developing flu-related complications.
The CDC holds National Influenza Vaccination Week in December as vaccinations tend to drop quickly after the end of November, leaving many vulnerable during the holiday season. Going on vacation or having relatives visiting from afar can expose people to different strains of the flu than what they have built a immune response to, which can spread illness for those unprotected. The flu vaccine protects against multiple strains of the flu viruses. Yearly vaccinations are recommended because flu viruses are always changing, and each year the vaccine is updated to better match circulating influenza strains.
The CDC recommends everyone over the age of 6 months to get a flu vaccine
