Patients with benign breast disease and breast cancer need more COVID-19 vaccines

Albeit the efficacy of COVID-19 vaccines in immunocompromised patients is undermined, it is still found beneficial. Patients with cancer have a much lower COVID-19 vaccination rate globally, and the vaccination coverage in breast cancer patients in China remains elusive. A total of 23029 patients with benign breast diseases and breast cancers were included in the study, and the vaccination rates of patients with benign breast tumors and other benign breast diseases, nonmetastatic and metastatic breast cancer were 44.0%, 54.7%, 19.2% and 9.6%, respectively. Breast cancer in situ patients had a similar vaccination rate with patients with benign breast tumors (45.9% vs 44.0%) while those with invasive breast cancer had much lower vaccination rates. The overall vaccination rate remains meager in breast cancer patients, and gap was found in patients with lower clinical stage. Hence vaccination should be further promoted among patients with benign breast diseases and breast cancer.
