Hannah Melchinger, from the Peter O'Donnell Jr. School of Public Health at UT Southwestern Medical Center in Dallas, and colleagues conducted two distinct, cross-sectional surveys assessing influenza vaccine uptake among U.S. adults.

达拉斯UT西南医学中心彼得·奥唐奈公共卫生学院的汉娜·梅尔辛格及其同事进行了两项不同的横断面调查，评估了美国成年人的流感疫苗接种情况。

The researchers found that from 2020 to 2024, overall flu vaccine uptake decreased, with more than 60 percent of U.S. adults surveyed in May 2020 indicating that they either received the influenza vaccine recently or intended to receive it in the coming months; this compared with 54 percent of U.S. adults surveyed in October 2024.

研究人员发现，从2020年到2024年，流感疫苗的整体接种率下降了。2020年5月调查的美国成年人中，超过60%表示他们最近已经接种了流感疫苗或打算在接下来的几个月内接种；相比之下，2024年10月调查的美国成年人中，这一比例为54%。

Significant declines were seen among demographic groups usually associated with higher vaccine uptake. People who were older than 35 years (11 percent decrease), male (13 percent), White (7 percent), non-Hispanic (5 percent), or more educated (16 percent) were significantly less likely to receive the influenza vaccine in 2024 versus 2022.

通常与较高疫苗接种率相关的人口群体中出现了显著下降。2024年与2022年相比，年龄超过35岁（减少11%）、男性（减少13%）、白人（减少7%）、非西班牙裔（减少5%）或受教育程度较高（减少16%）的人群接种流感疫苗的可能性显著降低。

'Changes in attitudes and intentions towards vaccination during and since the COVID-19 pandemic have been associated with several factors, including changes in perceived risk and the rise of vaccine-related mis- and disinformation,' the authors write.

“在新冠疫情期间及之后，对疫苗接种的态度和意图的变化与多种因素相关，包括感知风险的变化以及与疫苗相关的错误和虚假信息的增加，”作者写道。
