Objective: A relevance of fear and concerns about vaccine development and its side effects are suggested to explain COVID-19 vaccine hesitancy. However, evidence supporting the phobic origin hypothesis of hesitancy for COVID-19 and other vaccinations remains indirect and elusive.
Method: We addressed this issue by investigating the existence of a relationship between fear conditioning, extinction, and the respective vaccination hesitancy and anxiety scores in a group of 25 individuals.
Results: Overall, we show that the general mechanism of fear extinction learning is impaired in individuals with high vaccine hesitancy. State and trait anxiety scores do not account for this result.
Conclusions: These findings suggest that attitudes against vaccination could be linked to an altered inhibitory learning process.

Recent surges in COVID-19 cases demonstrate the unabated transmissibility of this disease. Despite the ongoing threat of contagion, however, uptake of the COVID-19 vaccines, especially as booster doses, remains suboptimal among eligible adults and children in the United States, as reported by the World Health Organization (WHO). Public attitudes toward these vaccines remain balkanized, with some groups harboring ambivalence or even opposition to receiving inoculation.

Purpose Of Review: Development of vaccines that protect against sexually transmitted infections (STIs), including for chlamydia, gonorrhea, and syphilis, has progressed greatly over the past decade. However, little research has been conducted to examine STI vaccine acceptance and hesitancy and how these factors may impact future uptake. This review examines literature that could provide additional insights into factors that would impact STI vaccine acceptance and hesitancy.
