流感季官方宣传启动：CDC呼吁6个月以上人群在10月底前完成流感疫苗接种
亚特兰大10月5日——据美国疾病控制与预防中心（CDC）流感季公开宣传口径，随着2026—27流感季临近，CDC年度流感疫苗宣传正式启动：建议所有6个月及以上人群接种本季流感疫苗，并尽量在10月底前完成——此时流感活动通常开始爬升，而疫苗产生保护力需要约两周。
CDC指出，65岁以上老人、慢性病患者、孕妇与5岁以下儿童是流感重症高风险人群，优先接种的意义在于降低住院与死亡风险。对65岁以上人群，CDC优先推荐三种「优选」疫苗：高剂量灭活疫苗、佐剂疫苗与重组疫苗。多数保险计划（含Medicare B部分）全额覆盖年度流感疫苗；无保险者可在县卫生局与连锁药房查询低价或免费接种点。
宣传材料同时回应两类常见误解：流感疫苗不会引起流感（注射剂为灭活或重组产品）；去年得过流感或接种过疫苗，不代表今年免种——流感病毒株逐年变化，疫苗配方按年更新。本站医疗频道10月9日另有流感季接种提醒稿，两篇分别依据CDC宣传口径与当季监测情况，内容不重复。
接种地点与时段方面，连锁药房（CVS、Walgreens等）与超市药房通常提供免预约接种，县卫生局网站可查社区接种点。赴诊时携带保险卡与既往接种记录即可；如对鸡蛋或疫苗成分有严重过敏史，应提前告知接种人员并在接种后按要求留观。

Flu Season Campaign Opens: CDC Urges Everyone 6 Months and Older to Get Vaccinated by End of October
ATLANTA, Oct. 5 — The CDC's annual flu vaccination campaign is under way as the 2026-27 season approaches, according to the agency's public flu-season guidance: everyone 6 months and older should get this season's flu vaccine, ideally by the end of October, because flu activity typically begins to climb afterward and protection takes about two weeks to build.
Adults 65 and older, people with chronic conditions, pregnant women and children under 5 face the highest risk of severe flu, and vaccination is aimed at cutting hospitalizations and deaths. For those 65 and older, the CDC preferentially recommends three options: high-dose inactivated, adjuvanted, and recombinant vaccines. Most insurance plans, including Medicare Part B, cover the annual flu shot in full; the uninsured can check county health departments and pharmacy chains for low-cost or free clinics.
Campaign materials answer two common misconceptions: flu vaccines cannot cause flu (the shots are inactivated or recombinant products), and having had flu or a shot last year does not substitute for this year's dose, because circulating strains change and the formula is updated annually. GSM's Health channel followed on Oct. 9 from a surveillance angle; the two items use different material.
On access: chain pharmacies such as CVS and Walgreens and supermarket pharmacies generally offer walk-in flu shots, and county health department sites list community clinics. Bring an insurance card and any prior vaccination record; anyone with a history of severe allergy to eggs or vaccine components should tell the vaccinator in advance and remain for the observation period afterward.
