About This Trial

Patients with cancer are considered vulnerable to severe acute respiratory syndrome coronavirus 2 infection and have been prioritized in the vaccination process in several countries, including Taiwan. In addition, international oncological societies favored COVID-19 vaccination for cancer patients on the basis of risk and benefits evaluation of all available data. However, patients with cancer were excluded from severe acute respiratory syndrome coronavirus 2 vaccines registrational trials and the investigators lack data regarding the safety and efficacy of vaccination in this population. Under this perspective, the investigators undertook a large prospective study enrolling patients with solid cancers, hematologic malignancies as well as healthy volunteers for the kinetics of anti-severe acute respiratory syndrome coronavirus 2 antibodies after COVID-19 vaccination on different anticancer therapy. Major inclusion criteria for this cohort of the study included: (1) age above 20 years; (2) presence of solid organ malignancies treated with immunotherapy, chemotherapy, Targeted therapy irrespective of the treatment phase; and (3) eligibility for vaccination.

Who May Be Eligible (Plain English)

Who May Qualify: 1. adults \>20 years old; 2. cancer patients under active anti-cancer therapy, including chemotherapy (n=80), targeted therapy (n=80) and immunotherapy (n=80); and cancer patients have been disease-free for ≥ 6 months (n=80) 3. cancer patients who were full vaccinated with any brand of vaccines or cancer patients who were unvaccinated agree to complete full vaccination later. 4. patients who agreed with the content of willing to sign a consent form of the study protocol. Who Should NOT Join This Trial: 1. Patients who refused the protocol of N-antibody test and Out-Patient Departments follow-up. 2. The investigators suggest to withdraw. 3. Patient asked to withdraw from the trial at any timepoints. Always talk to your doctor about whether this trial is right for you.
