The most recent FluView report shows increasing flu activity in the United States. Ongoing flu activity is expected for several weeks.

CDC reports this season’s flu vaccine is nearly 60 percent effective against all circulating viruses. It is not too late to get your flu vaccine this season.

CDC recommends a yearly flu vaccine for everyone 6 months and older. Vaccination can reduce flu illnesses, doctors' visits, and missed work and school due to flu, as well as prevent flu-related hospitalizations. More than 146.4 million doses of flu vaccine have been distributed in the United States.

With several weeks of flu activity still to come, getting vaccinated now can still offer protection. Find a Vaccine.
