Adolescent receptiveness to dentist involvement in COVID-19 and HPV vaccination

Human papillomavirus (HPV) and COVID-19 can be prevented and mitigated by vaccines. Few studies have focused on dentists' role in vaccine decision making, and even fewer have explored adolescent perspectives; a target population for both vaccinations. This study aimed to address this gap with a focus on whether opinions vary between diseases.

We administered a validated cross-sectional survey to adolescent patients (11-19 years) in an orthodontic clinic in Vancouver, British Columbia from July-August 2023. The survey included questions pertaining to patient background, vaccine history and knowledge, and dentists' roles in vaccination education, discussion, and administration. Responses were compiled and analyzed to determine differences between vaccines and across demographic groups.

Adolescents surveyed (n=93) overall agreed with dentist involvement in COVID-19 and HPV vaccines, with variability according to disease and dentist role. Comfort with dentist-administered vaccines was higher for COVID-19 (60 %) than HPV (37 %, p<0.05). There was a significant knowledge difference, with 85 % aware that the COVID-19 vaccine can prevent severe illness, but only 22 % aware that the HPV vaccine can prevent oropharyngeal cancer (p<0.05). Patients showed overall willingness to discuss COVID-19/HPV vaccines with dentists (58 % and 49 %) and less agreement that dentists were qualified to educate about COVID-19/HPV vaccines (43 % and 37 %).

Findings indicate mixed adolescent perception of including dentists in vaccinations, with higher comfort around COVID-19 over HPV vaccines. Openness to discussion may present an opportunity for dentists to expand scope of practice into additional education, particularly around HPV and its connection with oropharyngeal cancer.
