中国疾控中心发布流感疫苗接种指南 建议8类人群优先接种

中国疾控中心于9月2日发布了《中国流感疫苗预防接种技术指南(2026-2027)》，明确建议医务人员、60岁及以上老年人、慢性病患者、养老机构人员、6月龄至5岁儿童、6月龄以下婴儿的家庭成员、托幼机构和中小学校人群、孕妇等8类人群优先接种流感疫苗1。

指南强调流感冬春季高发，建议在9—10月完成接种以获得冬季保护1。接种后2—4周即可产生具有保护水平的抗体1。疫苗类型包括三价灭活疫苗(IIV3)和三价减毒活疫苗(LAIV3)1。针对儿童接种，首次接种灭活疫苗的6月龄至9岁儿童需要接种2剂次，间隔≥4周；既往已接种过流感疫苗的儿童则只需1剂次1。

The Chinese Centers for Disease Control and Prevention released the "Technical Guide for Influenza Vaccine Immunization in China (2026-2027)" on September 2, outlining vaccination priorities for the upcoming flu season 1. The guidance identifies eight population groups recommended to receive flu vaccines as a matter of priority: healthcare workers, adults aged 60 and older, individuals with chronic diseases, staff at nursing homes and welfare facilities, children aged 6 months to 5 years, household members of infants under 6 months, people in schools and detention facilities, and pregnant women 1.

The CDC emphasized that influenza typically peaks during winter and spring months, making timely vaccination essential for winter protection 1. It recommends completing vaccinations between September and October, though vaccination remains advisable throughout the entire flu season 1. The available vaccine options include inactivated trivalent vaccine (IIV3) and live attenuated trivalent vaccine (LAIV3) 1. Children aged 6 months to 9 years receiving inactivated vaccine for the first time require two doses spaced at least four weeks apart; those with prior vaccination history need only one dose 1. Protective antibodies typically develop within two to four weeks after vaccination 1.
