Influenza vaccination is one of the most important strategies for preventing influenza. However, the influenza vaccination rate in China remains low. During the COVID-19 pandemic, people held different attitudes toward the COVID-19 vaccine. In the post-pandemic era, do the varying attitudes toward the COVID-19 vaccine affect the intention to receive influenza vaccination?
Based on the influence of presumed influence (IPI) model and spillover effects, this study employed structural equation modeling for multi-group comparison to analyze questionnaires from 613 participants, using instruments such as the Perceived Media Influence on Others Scale (PMIO), the Susceptibility to Influenza Scale (SI), and the Attitude toward Influenza Vaccine Scale (AIV).
The key findings are as follows: (1) Information exposure to the influenza vaccine significantly influences perceived media influence on others. (2) Perceived media influence on others does not directly impact the intention to receive influenza vaccination but rather affects it through attitude toward the influenza vaccine. (3) Moreover, multi-group analyses revealed differences in the IPI model among audiences with different attitudes toward the COVID-19 vaccine. These differences demonstrated that prior attitudes toward the COVID-19 vaccine can influence attitudes toward similar influenza vaccines, thus demonstrating the existence of spillover effects.
Attitude toward the COVID-19 vaccine can influence the intention to receive the influenza vaccination. Those with a negative attitude toward the COVID-19 vaccine are significantly influenced by susceptibility to influenza. Perceived media influence affects the intention to receive the influenza vaccination among those with a positive attitude toward the COVID-19 vaccine.
流感疫苗接种是预防流感的最重要策略之一。然而，中国的流感疫苗接种率仍然很低。在 COVID-19 大流行期间，人们对 COVID-19 疫苗持有不同的态度。在后疫情时代，对 COVID-19 疫苗的不同态度是否会影响接种流感疫苗的意愿？
本研究基于假定影响（IPI）模型和溢出效应，采用结构方程模型进行多组比较，对 613 名参与者的问卷进行分析，使用了感知媒体对他人影响量表（PMIO）、流感易感性量表（SI）和流感疫苗态度量表（AIV）等工具。
主要发现如下：（1）对流感疫苗的信息暴露显著影响对他人的感知媒体影响。（2）感知媒体对他人的影响不会直接影响接种流感疫苗的意愿，而是通过对流感疫苗的态度影响它。（3）此外，多组分析显示，不同 COVID-19 疫苗态度群体的 IPI 模型存在差异。这些差异表明，对 COVID-19 疫苗的先前态度可以影响对类似流感疫苗的态度，从而表明存在溢出效应。
对 COVID-19 疫苗的态度会影响接种流感疫苗的意愿。对 COVID-19 疫苗持负面态度的人对流感的易感性影响显著。对 COVID-19 疫苗持积极态度的人，感知媒体影响会影响接种流感疫苗的意愿。
