NCT05313074

Brief Summary

Our study highlights a low degree of neutralization-afforded protection mounted by CoronaVac in cancer patients when compared with healthy volunteers, especially patients who received chemotherapy. Further booster doses, beyond the conventional two-dose regimen might be needed for recipients of CoronaVac to maintain a long-term anamnestic response.
