Vaccination may provide less protection against influenza in patients older than 65 years. In an effort to improve the immunogenicity of influenza virus vaccine in elderly adults, a high-dose trivalent inactivated influenza vaccine (Fluzone High-Dose) was been developed. In a multicenter, randomized, double-blind controlled trial involving elderly adults (≥65 years), those who received the high-dose vaccine exhibited a statistically significantly higher seroconversion rate than those who received the standard-dose vaccine.
