About FLUCELVAX TRIVALENT (2024/2025)

Flucelvax Trivalent (2024/2025) is a medication aligned to the HCPCS CPT Drug Code: 90661 for billing, pricing, and reimbursement purposes in the United States. Classified under Vaccine, it is administered via the intramuscular route and manufactured by Seqirus.

According to CMS Drug Use Information: This vaccine is used to help prevent influenza ("flu") in people 6 months and older. Influenza can cause serious (rarely fatal) illness, especially in people at high risk from the infection (such as young children, older adults, people with chronic health problems). This vaccine is also called the seasonal flu shot. It works by increasing the body's natural defense (immunity) against the virus. Vaccination is the best way to protect against this infection. It can help prevent the infection or decrease the seriousness of the illness if you become infected. Since different types of flu viruses cause infection every flu season, a new vaccine is made and given every year. Vaccines may not fully protect everyone who receives them. The flu vaccine does not cause the flu.
