It's the flu season and the best way to protect yourself is with a flu shot.

Those interested in getting the vaccine should get it as soon as it’s available.

Officials say it takes about two weeks after vaccination for antibodies to develop in the body and provide protection against the flu, and then the benefits last for up to a year.

The flu vaccine is needed every year because flu viruses are constantly changing. It’s not unusual for new flu viruses to appear each year.

The flu vaccine is formulated each year to keep up with the flu viruses as they change.
