长者冬季疫苗怎么打：疾控中心建议75岁以上接种一剂RSV疫苗、流感疫苗6个月以上人人打
美国疾病控制与预防中心（CDC）在其呼吸道病毒接种数据页上重申本季接种口径：呼吸道合胞病毒（RSV）疫苗建议75岁及以上成年人接种一剂，50至74岁、重症风险较高的人也建议接种；流感疫苗建议6个月以上所有人每个季度接种；新冠疫苗建议18岁及以上成年人接种。
CDC 说，RSV 通常只引起类似感冒的轻症，但对婴儿与长者可能特别严重，可引发支气管炎、肺炎等肺部感染。美国食品药品管理局已于2026年8月批准用于2026至2027年秋冬病毒季的新冠疫苗。
进入冬季，长者可对照自己的年龄与健康状况，把流感、RSV 与新冠三件事一次问清：RSV 疫苗目前是一剂制、不是每年打；流感疫苗则要每个流感季重新接种。婴幼儿的 RSV 防护另有母体接种或婴儿抗体针两条路线，由儿科医生按 CDC 口径判断。（来源：美国疾病控制与预防中心）
Winter Vaccines for Older Adults: CDC Recommends One RSV Dose for Everyone 75 and Older, Flu Shots From 6 Months Up
The U.S. Centers for Disease Control and Prevention (CDC) restates this season's guidance on its respiratory virus vaccination page: a single dose of RSV vaccine is recommended for all adults ages 75 and older, and for adults ages 50 to 74 who are at increased risk of severe RSV; a seasonal flu vaccine is recommended for everyone aged 6 months and older; and COVID-19 vaccination is recommended for all adults ages 18 and older.
The CDC says RSV usually causes mild, cold-like symptoms but can be especially serious for infants and older adults, leading to lung infections such as bronchitis or pneumonia. The Food and Drug Administration approved the COVID-19 vaccines for the 2026-27 fall and winter virus season in August 2026.
As winter approaches, older adults can sort out all three shots in one conversation with their clinician: the RSV vaccine is currently a one-time dose rather than a yearly shot, while the flu vaccine is renewed each season. Protection for infants follows a separate path, through maternal vaccination or an infant antibody shot, as the CDC describes. (Source: U.S. Centers for Disease Control and Prevention)
