The study found that after their first dose, only 29 percent of the cancer patients tested positive for Covid antibodies.

In the group of cancer patients who were antibody-negative, 74 percent were going through chemotherapy, a treatment known for weakening a person’s immune systems.

The researchers suggest that more work is needed to identify specific types of chemotherapy that may be more likely to inhibit antibody production.
The results indicate that cancer patients may build up immunity more slowly after vaccination, wrote the researchers.
