Predicting Human Papillomavirus Vaccination Uptake in Saudi Arabia: Analyzing Health Belief Model Constructs, Vaccine Hesitancy, and Pap Smear Uptake

Background: Cervical cancer is among the most common cancers affecting women worldwide, with high morbidity and mortality in low- and middle-income countries. In Saudi Arabia, most cases are diagnosed at a late stage despite the availability of free HPV vaccination and screening. Objectives: To identify Saudi women’s perceptions of the HPV vaccine using the Health Belief Model, estimate willingness to receive the HPV vaccine and the factors influencing it, assess uptake of Pap smear and HPV vaccine, and define barriers to both practices. Methodology: A cross-sectional study of a convenience sample of 1334 Saudi women aged 16 to 65 years, from all regions of Saudi Arabia, was conducted. Data were collected via an online questionnaire that included sociodemographic characteristics, beliefs about the HPV vaccine based on the Health Belief Model, vaccine hesitancy, and HPV vaccine and Pap smear uptake. Data were analyzed using SPSS version 29. Results: Only 6% completed their vaccination series or received at least one dose; 37.3% planned to get vaccinated; and 56.7% stated they do not intend to get vaccinated. The main reasons for vaccine refusal were lack of trust (41.8%) and fear of side effects (32.3%). Only 21% had undergone Pap smear testing, with barriers including embarrassment and fear. Among the HBM constructs, perceived susceptibility, benefits, and barriers remained statistically significant predictors of HPV vaccination. Increased perceived susceptibility and benefits raise the likelihood of accepting the HPV vaccine, while higher perceived barriers lessen it. Vaccine hesitancy had a significant negative effect on willingness to receive the HPV vaccine (OR = 0.78, 95% CI 0.69–0.90, p < 0.01). Additionally, Pap smear uptake was an independent predictor of the intent to get the HPV vaccine (OR = 1.78, 95% CI 1.25–2.54, p < 0.01). The independent factors influencing HPV vaccine uptake were largely similar to those affecting the willingness to receive the vaccine, except for age, perceived benefits, and Pap smear uptake. Conclusions: There is a gap between Saudi women’s intention to get HPV vaccinated and actual vaccination. Women who saw a high risk of HPV-related cancer, believed in vaccine efficacy, had a Pap smear, and were open to vaccination were more likely to vaccinate. Hesitant women and those perceiving barriers were less likely to vaccinate or consider it. The main gaps for future campaigns are perceptions of HPV severity and cultural factors influencing decision-making. Emphasizing HPV as a cancer-related virus rather than a sexually transmitted infection can reduce barriers and highlight its severity.
