Cancer usually requires a determination of whether or not the New Crown vaccine can be given based on the specific condition, rather than by the specific type of cancer. For cancer patients who are in a stable stage of recovery and are not receiving radiotherapy or chemotherapy, and who do not have adverse factors such as contraindications to the New Crown vaccination, they are usually able to receive the New Crown vaccine. For cancer patients whose conditions are not stabilized and whose own immunity is relatively poor, they may not be able to produce antibodies after receiving the New Crown vaccine, which may easily lead to vaccination failure. Moreover, the vaccination of cancer patients in this situation may lead to a further decline in the body’s immune function, thus causing aggravation of the disease. Therefore, this condition is not allowed to take the New Crown Vaccine. Before receiving New Crown vaccine, cancer patients are advised to consult a professional doctor and actively listen to the doctor’s advice in the light of their own conditions. Meanwhile, they need to do a good job of personal protection and wear a good mask when going out.
