The Center for Disease Control provides the following updates on the 2017 flu season:
- As of early November 2017, only about 2 out of every 5 persons 6 months and older in the United States had received a flu vaccination.
- People not yet vaccinated this season should get a flu vaccination as soon as possible.
- The nasal spray flu vaccine (live attenuated influenza vaccine or LAIV) should not be used for the 2017–18 season. Parents who previously got their child vaccinated with the nasal spray vaccine should get their child vaccinated with an injectable vaccine this season rather than having their child stay unprotected this flu season.
