# Sanofi Patient Connection Patient Guide: How to Get Flublok Quadrivalent (Influenza Vaccine (Recombinant, Quadrivalent)) at Low or No Cost Flublok Quadrivalent is a recombinant influenza vaccine manufactured by Sanofi Pasteur, Inc., designed to protect against flu strains in people aged 9 and older, and eligible patients may access it at no cost through the **Sanofi Patient Connection** program.[1][3][4] ## About Flublok Quadrivalent **Flublok Quadrivalent** is a flu vaccine indicated for active immunization to prevent disease caused by influenza A and B strains matching the antigens in the vaccine.[4] It's approved for individuals **9 years of age and older**, making it suitable for children, teens, adults, and seniors.[4][6] Unlike traditional egg-based flu shots, Flublok uses **recombinant protein-based technology**, ensuring an exact match to FDA-selected flu strains without using live virus in production.[4] Key benefits include: - **3x more antigen** than standard flu shots, potentially offering stronger protection.[4][6] - In adults 50+, it showed **30% better protection** against flu compared to a standard-dose vaccine like Fluarix Quadrivalent.[4] - Real-world data indicated **31% fewer flu-related hospitalizations** versus cell- or egg-based shots in people 18+.[4] Common side effects are mild, such as injection-site pain, headache, fatigue, muscle pain, and malaise, which are similar to other flu vaccines but may be slightly more frequent in some groups.[6] Always consult your healthcare provider to see if Flublok is right for you, especially if you have allergies or comorbidities like heart disease or diabetes.[4] ## Who Qualifies for Sanofi Patient Connection?
