The flu affects between 5 and 20 percent of the U.S. population each year. An annual flu vaccine is the best way to reduce your risk of getting sick and spreading it to others. This benefit allows members to receive the flu shot for a $0 copayment. Members can take advantage of this benefit at a network pharmacy. Coverage includes the full cost of the vaccine and administration fee if the member receives the shot in a network doctor’s office. Any associated office visit charges follow regular Plan coverage rules.
