RESUMO
(1) Background: Vaccine hesitancy and rejection are major threats to controlling coronavirus disease 2019 (COVID-19). There is a paucity of information about the attitudes of cancer patients towards vaccinations and the role of clinical oncologists in influencing vaccination acceptance. (2) Methods: Cancer patients and caregivers were invited to participate in a webinar and two surveys (pre- and post-webinar) assessing intention and thought processes associated with receiving COVID-19 vaccines. (3) Results: Two hundred and sixty-four participants participated in the webinar and registered to take at least one survey. Participants reported receiving most of their COVID-19 vaccine information from their doctor, clinic, or hospital. Before the webinar, 71% of participants reported the intention to receive a COVID-19 vaccine, 24% were unsure, and 5% had no intention of receiving a vaccine. The strongest predictors of vaccine enthusiasm were (a) planning to encourage the vaccination of family, friends, co-workers, and community, and (b) physician recommendation. The chief reason for vaccine hesitancy was a fear of side effects. After the webinar, 82.5% reported the intention to receive a vaccine, 15.4% were still unsure, and 2% stated that they had no intention of receiving a vaccine. The webinar shifted the attitude towards vaccine enthusiasm, despite an already vaccine-enthusiastic population. Communicating about vaccines using positive framing is associated with greater vaccine enthusiasm. (4) Conclusions: Patient education programs co-hosted by multiple stakeholders and delivered by oncologists can increase cancer patient enthusiasm for COVID-19 vaccination.
