Trust in HPV Vaccine Effectiveness and Safety and Willingness to Initiate HPV Vaccination Among Unvaccinated Female College Students Recruited Through University-Based Online Networks in China: A Cross-Sectional Study
A cross-sectional study of unvaccinated female college students in China found that higher trust in the effectiveness and safety of HPV vaccines, including both domestic and imported varieties, is significantly associated with a greater willingness to initiate vaccination.

Cervical cancer remains one of the most significant threats to women's health globally, yet it is largely preventable. The root cause of most cases is a persistent infection with a specific virus known as human papillomavirus, or HPV. Just as a shield can stop a projectile, a vaccine designed against this virus can prevent the infection and the dangerous cellular changes that follow. However, the success of any vaccination campaign depends less on the science of the shot itself and more on the people who are asked to take it. For young women, particularly those in college, the decision to get vaccinated is a complex negotiation. It involves weighing the promise of future protection against immediate concerns about cost, access, and, perhaps most critically, trust. When a person does not trust that a medicine will work or that it is safe to take, the most effective medical intervention in the world will sit unused on a shelf.
In a recent study, researchers set out to understand exactly how these feelings of trust shape the willingness of young women in China to receive the HPV vaccine. They focused on a specific group: female college students who had not yet been vaccinated. The researchers recognized that trust is not a single, monolithic feeling. A student might believe a vaccine is highly effective at preventing disease but still harbor deep fears about its safety. Conversely, another might feel the vaccine is safe but doubt its necessity or power. Furthermore, in the Chinese market, vaccines come from different sources: some are produced domestically, while others are imported. The study aimed to see if trust in the effectiveness of the vaccine, trust in the safety of locally made versions, and trust in the safety of imported versions each played a unique role in a student's decision to get vaccinated.
To find the answers, the team conducted a large online survey between January 2025 and March 2026. They reached out to students at twenty-four universities across twelve different provinces and regions in China, including areas as diverse as Shandong, Guangdong, and Tibet. The recruitment happened through university health centers, student offices, and online networks, gathering a total of 2,215 responses from students who confirmed they had never received an HPV shot. The survey asked these students to rate their willingness to get vaccinated on a scale from very unwilling to very willing. Crucially, it also asked them to rate their trust in three specific areas: the vaccine's ability to prevent cancer, the safety of vaccines made in China, and the safety of vaccines made abroad. The researchers then used statistical methods to see how these ratings of trust lined up with the students' stated willingness to get the shot, while carefully accounting for other factors like age, where they lived, their field of study, and how much they followed news about vaccine side effects.
The results painted a clear picture of the relationship between belief and action. Among the students surveyed, only about 37 percent reported being highly willing to get the vaccine. However, this willingness was not evenly distributed; it rose dramatically as trust increased. For students who expressed very little trust in the vaccine's ability to prevent cervical cancer, only a tiny fraction, roughly 7 percent, said they were willing to get vaccinated. In stark contrast, among those who expressed very high trust in the vaccine's effectiveness, nearly 80 percent said they were willing to receive it. This pattern held true for safety concerns as well. Students who were very distrustful of the safety of domestically produced vaccines showed low willingness, while those who were very trustful showed much higher willingness. The same trend appeared for imported vaccines.
When the researchers adjusted their analysis to account for other variables, such as the students' age, their major, and whether they had seen news reports about adverse vaccine events, the connection between trust and willingness remained strong. The data showed that students who were very trustful of the vaccine's effectiveness were more than five times as likely to report high willingness compared to those who were very distrustful. Similarly, high trust in the safety of imported vaccines was associated with a fivefold increase in willingness, while high trust in the safety of domestic vaccines was associated with a threefold increase. These numbers suggest that while trust in effectiveness is a powerful driver, trust in safety—whether for local or foreign products—also plays a substantial and independent role in the decision-making process.
The study also explored how students viewed the cost of the vaccine. Interestingly, the relationship between price and willingness was not a simple line. Students who said they could only afford a very low price were not necessarily the most willing to get vaccinated, nor were those willing to pay more automatically more eager. The researchers noted that the price a student is willing to pay might reflect more than just their budget; it could also signal their preference for a specific type of vaccine, their confidence in the value they are getting, or their uncertainty about the entire process. Because the study was a snapshot in time, it could not prove that changing a student's mind about safety would automatically lead them to get vaccinated, but it did establish a very strong link between what they believe and what they say they are ready to do.
Ultimately, the research highlights that for unvaccinated college women in China, the path to vaccination is paved with confidence. The findings suggest that public health efforts cannot rely on a single message. To increase uptake, communication strategies may need to address effectiveness and safety as distinct concerns, and they may need to acknowledge that students hold different levels of trust for vaccines depending on where they are made. While the study used a convenience sample and cannot represent every student in the country, the consistency of the results across different regions and university types offers a compelling insight: when young women trust that a vaccine works and trust that it is safe, they are far more likely to take the step to protect their health.
