COVID-19 Vaccination in Patients with Cancer

Simple Summary Patients with cancer are concerned about the effects of the COVID-19 vaccination while authorities search for ways to encourage vaccination; however, many points are still unclear. To remedy this situation, we conducted an online survey of 1182 female patients with cancer. The results showed that 768 were concerned about the vaccine, and 726 consulted with their attending physicians about the vaccination. The results also showed significantly higher vaccination rates among the patients who had consulted with their physicians. We found that consulting with attending physicians appeared to be linked to reduced anxiety, decisions about the timing of the vaccination, and higher vaccination rates. This was corroborated by the result of the cross-analysis of vaccination status and information sources about the vaccination. Therefore, we concluded that consulting with a physician about vaccination alleviates the concerns of patients with cancer and encourages them to get vaccinated. Patients with cancer are concerned about the effects of the COVID-19 vaccination. We conducted an online survey on the COVID-19 vaccination status and side effects among patients with cancer in Japan between 8 and 14 August 2021. We included 1182 female patients with cancer aged 20-70 years and registered on an online patient website. Of the patients, 944 had breast cancer, 216 had gynecological cancer, 798 were undergoing drug/radiation therapy, and 370 were in follow-up. At the time of the survey, 885 patients had already received at least one dose. Of these, 580 had also received their second dose. The incidence rate of side effects was equivalent to previous reports. In patients with breast cancer, problems such as the onset or worsening of lymphedema or axillary lymphadenopathy metastasis requiring differential diagnosis were encountered following vaccination. A total of 768 patients were concerned about the vaccine at some point, and 726 consulted with their attending physicians about the timing or side effects of the vaccination. Of the 110 patients undergoing chemotherapy or radiation therapy, 75 adjusted the timing of the vaccination based on their therapy. The cross-analysis revealed that 81% of those who consulted their physician had received at least one dose of the COVID-19 vaccination compared with 65% of those who had not consulted their physician. Consulting with a physician about the COVID-19 vaccination was found to alleviate the concerns of patients with cancer and encourage them to get vaccinated.
