重阳时节长者健康：CDC 对65岁以上长者优先推荐三款流感疫苗 9至10月为理想接种期
亚特兰大——重阳节前后正值北半球流感季开始。美国疾病控制与预防中心（Centers for Disease Control and Prevention，CDC）2026年9月2日发布的临床考量显示，对65岁以上长者，CDC 优先推荐三款流感疫苗：高剂量灭活疫苗 Fluzone High-Dose、重组疫苗 Flublok 与佐剂灭活疫苗 Fluad。CDC 同时表示，若上述优先疫苗无货，不应推迟接种，应改用其他适龄流感疫苗。
据 Immunize.org 对 CDC 指引的汇总（2026年10月11日复核），美国家庭医师学会（AAFP）将同样三款疫苗列为65岁以上长者的优先选项，并另纳入 mFlusiva——一款2026年8月获批用于50岁以上人群的 mRNA 流感疫苗；CDC 9月2日的临床考量未包含该产品信息。CDC 与医学学会建议，只需接种一剂流感疫苗的人群，理想接种时间为9月或10月；流感病毒仍在传播且疫苗未过期时，10月之后应继续接种。
数据方面，CDC 估计，近年来65岁以上人群约占季节性流感相关死亡的70%至85%、占流感相关住院的50%至70%，是流感重症负担最重的年龄段。全国老龄委员会（National Council on Aging，NCOA）的长者流感疫苗指南与 CDC 口径一致，同样列明上述三款优先疫苗，并提醒长者与医疗提供者商量适合自己的疫苗。

Senior Health in Chongyang Season: CDC Preferentially Recommends Three Flu Vaccines for Adults 65 and Older, With September–October the Ideal Window
ATLANTA — The Double Ninth Festival arrives as flu season begins in the Northern Hemisphere. In clinical considerations published September 2, 2026, the Centers for Disease Control and Prevention (CDC) preferentially recommends three influenza vaccines for adults age 65 and older: Fluzone High-Dose, Flublok (recombinant) and Fluad (adjuvanted). The CDC also states that if none of the preferentially recommended vaccines is available, another age-appropriate flu vaccine should be given rather than delaying vaccination.
According to Immunize.org's summary of CDC guidance, last reviewed October 11, 2026, the American Academy of Family Physicians (AAFP) includes the same three products as preferred options for adults 65 and older, and also includes mFlusiva, an mRNA flu vaccine licensed in August 2026 for adults age 50 and older; the CDC's September 2 clinical considerations did not include information on mFlusiva. The CDC and medical societies recommend that most people who need only one dose of flu vaccine be vaccinated ideally in September or October, and that vaccination continue after October as long as influenza viruses are circulating and unexpired vaccine is available.
The CDC estimates that in recent years, people 65 and older have accounted for roughly 70% to 85% of seasonal flu-related deaths and 50% to 70% of seasonal flu-related hospitalizations, the greatest burden of severe flu disease of any age group. The National Council on Aging's (NCOA) flu vaccine guide for older adults echoes the CDC's three preferred vaccines and advises older adults to talk with a healthcare provider about which vaccine is right for them.
