The aims of this study were to assess healthcare workers' intention to receive the booster dose of COVID-19 vaccine and to identify predictive factors among healthcare workers. A cross-sectional study was conducted among healthcare workers selected in two provinces, Kasai Oriental, and Haut-Lomami. Data were collected using a questionnaire administered through structured face-to-face interviews, with respondents using a pre-tested questionnaire set up on the Open Data Kit (ODK Collect). All data were analyzed using SPSS v26.0 (IBM Corporation, Armonk, NY, USA). Vaccination coverage for COVID-19, considering declarations by health workers, is around 85.9% for the province of Kasai Oriental and 85.8% for Haut-Lomami. A total of 975 responses were collected, 71.4% of health workers at Kasai Oriental and 66.4% from Haut-Lomami declared a definite willingness to receive a COVID-19 vaccine booster. The duration of protection was the main reason for accepting a booster COVID-19 dose for 64.6% of the respondents. Logistic regression analysis showed that having chronic diseases (aOR = 2.95 [1.65-5.28]), having already received one of the COVID-19 vaccines (aOR = 2.72 [1.43-5. 19]); the belief that only high-risk individuals, such as healthcare professionals and elderly people suffering from other illnesses, needed a booster dose (aOR = 1.75 [1.10-2.81]). Considering the burden of COVID-19, a high acceptance rate for booster doses could be essential to control the pandemic.

Primary care professionals (PCPs) can increase coverage by using presumptive recommendations to introduce HPV vaccination in a way that assumes parents want to vaccinate. Through semi-structured interviews, we explored PCPs' experiences and perceptions of using presumptive recommendations in rural- and non-rural-serving primary care clinics in North Carolina. Thematic analysis revealed that most PCPs in rural and non-rural contexts used presumptive recommendations and felt the strategy was an effective and concise way to introduce the topic of HPV vaccination to parents. At the same time, some PCPs raised concerns about presumptive recommendations potentially straining relationships with certain parents, including those who had previously declined HPV vaccine or who distrust medical authority due to their past experiences with the healthcare system. PCPs dealt with these challenges by using a more open-ended approach when introducing HPV vaccination to parents. In conclusion, our findings suggest that PCPs in both rural and non-rural settings see value in using presumptive recommendations to introduce HPV vaccination, but to adequately address concerns and ensure increased HPV vaccine uptake, PCPs can use simple and culturally sensitive language to ensure fully informed consent and to maintain parental trust. And to further strengthen HPV vaccine discussions, PCPs can utilize other effective HPV communication techniques, like the Announcement Approach, in discussing HPV vaccinations with hesitant parents.</p>","PeriodicalId":49067,"journal":{"name":"Human Vaccines & Immunotherapeutics","volume":null,"pages":null},"PeriodicalIF":4.1,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11085946/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140872327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A reduction in CIN2+ recurrences by 90% (95% confidence interval: 12-99%) was documented in 9vHPV-vaccinated participants compared to women undergoing only surgical excision. Moreover, vaccinated women with a positive cone margin showed a 42% (though non-significant) reduction in relapse (<i>p</i> = .661). Full post-conization vaccination with the 9vHPV contributed to an additional reduction in the risk of CIN2+ recurrence.
